John Surtees struggles to restart his stalled Lola T70 Mk3 Aston Martin at the commencement of the Nurburgring 1000 Km, 28 May 1967…

Alongside him , slightly obscured, poleman Phil Hill in the sensational Chaparral 2F Chev is also slow away, meanwhile a gaggle of Porsche 910’s sprint away, likely culprits the works cars of Rolf Stommelen, Gerhard Mitter and Jo Siffert.

A happy confluence of events was the construction of Aston Martin’s new V8 engine and racer/entrant Jackie Epstein’s approach to Eric Broadley to build a coupe variant of the 1966 Can Am Championship winning Lola T70 Spyder Group 7 machine. John Surtees of course won the very first Can Am series in a T70 Mk2 Chev. Eric Broadley and Surtees formed Lola Racing Ltd as a works development and racing arm, Surtees honed the T70, he outlined his philosophy in developing the car in a MotorSport interview in August 2003.

‘With a long distance car you can’t have something that rides on a knife edge like a top F1 car…You are trying to get consistency, you don’t want an unpredictable and volatile character. By the time the T70’s got some running in them they were very driveable, very predictable cars which you could drive up to the limit and perhaps a little bit over. This gave the driver confidence’.

Surtees in ‘SL73/101’ at the Nurburgring upon the Lola Astons race debut. The sensational body of the Mark 3 was designed by New Zealander Jim Clark for Specialised Mouldings to make. It was the first racing car to use carbon-fibre reinforced bodywork. Tony Southgate, then at Lola, spent many hours in the Imperial College wind tunnel to give both low drag and some downforce front and rear. The cars side windows were made of Perspex and had small diagonal flaps which could be set open to aid cockpit ventilation, as here (Schlegelmilch)

Surely one of the swoopiest, voluptuous and sexiest racers ever- the Lola T70 Mk3 Coupe ‘SL73/101’ was the first Lola Aston built and was shown to rapturous crowd approval at the annual Racing Car Show at London’s Olympia in January 1967. Tadek Marek’s new Aston Martin ‘DP218’ V8 engine also made its first public appearance at the show on the Surtees Racing stand, the announcement of the relationship between the concerns- Lola, Astons and Surtees was made at the show.

On the face of it the association had every chance of success.

The combination of one of sportscar racings best chassis, a lightweight, powerful engine which promised to provide the Lola with better balance than the Chev engined T70’s and John Surtees track testing ability and sheer speed promised much. Aston Martin chief David Brown was of the view that ‘racing improves the breed’ whilst his chief engineer Tadek Marek was not especially enamoured of the a high risk strategy. After all, his new engine was designed as a road car motor not a race engine.

Undaunted David Brown proceeded and Aston Martin Lagonda supplied special versions of Marek’s design with a capacity of 5008.5cc- bore/stroke of 98x83mm. The all aluminium, duplex chain driven quad cam, 2 valve, dry-sumped, Lucas fuel injected V8 was quoted by Astons as producing 450bhp @ 6750rpm and 413 lb/ft of torque at Le Mans 1967.

Note the shape of the aluminium monocoque chassis, high pressure fuel pumps, note that the engine is now Lucas injected compared with the Webers used at the Le Mans test weekend. DOHC, but 2 valve and chain driven cams. The two suspension radius rods are clear as is the top of the coil spring and roll bar. Ditto the ‘luggage box’ (Schlegelmilch)

‘DP218 was first tested in a T70 Spyder in Autumn 1966. At that first development stage, using a compression ratio of 11:1 and fitted with four Weber 48IDA carburettors the engine was quoted as giving 421bhp @ 6500rpm and 386 lb/ft of torque. Testing showed there were many problems with the engine most notably the motor popped a rod through the side of its aluminium block due to oil starvation. Eventually a much developed engine, one of a batch of ten that had been delivered, with attention to the dry sump system, was installed in March 1967 into the new Coupe for Team Surtees to run. The most obvious problems in testing were a bad vibration and an inability to rev beyond 6100 rpm.

The big, booming car was the third fastest machine present in the dry and fastest in the wet at the Le Mans test days on April 8 and 9…

The car was fast through the corners but was unable to top 186mph as a consequence of not being able to pull more than 6000rpm on the Mulsanne. Aston’s were convinced that Lucas fuel injection, which was shortly to be installed would cure the problem. The quickest cars were the works Ferrari P4’s of Bandini, Amon, Scarfiotti and Parkes with Bandini at the end of the day the quickest. The two Fords driven by McLaren and Donohue ‘rumbled ominously but did not press the button’. Mind you the Mark 4 was timed at 205mph and Ferrari 198 on the Mulsanne.

The MotorSport report of the test weekend wryly observes ‘…the two giants (Ford and Ferrari) kept an eye on Lola, Ford knowing that their whole racing effort was born of the brain of Eric Broadley and Ferrari knowing that Surtees can never be underrated’… ‘Although on paper Ferrari left Le Mans as top dog, no one was being fooled by the freak circumstances, for had it been dry on Sunday it might have been a different story and both teams were very impressed with the Lola Aston Martin efforts, remembering their own experiences when running a brand new design for the first time. It seems that Ford did not want to run in the rain for fear of a repetition of the accident to Hansgen last year…’

So, in short, Lola Astons peers were impressed by the car and the threat it potentially represented.

Lola Astons first race appearance was at the Nurburgring 1000 Km on May 28…

It was planned to race the car at Spa but it was not ready in time so the beautiful beast made its race debut at the daunting Nurburgring. Lucas fuel injection was amongst the latest refinements to DP218.

On the face of it the car was far from the most nimble present, nor was the Phil Hill/Mike Spence Chaparral 2F Chev on pole, but Surtees popped ‘101’ second on the grid, he shared the drive with David Hobbs. Porsche 910’s were the next quickest group of cars.

Surtees stalled the unfamiliar car at the start but was soon up to 7th place by lap seven when a rear wishbone broke going down through the Fuchsrohre. Surtees managed to stop the car without damage to either the machinery or the driver, but that was the end of the meeting- and of useful testing miles. Udo Schutz and Joe Buzzetta won the race in a 910.

Great contrasting shot of the ‘standard’ T70 rear bodywork at left and ‘more streamlined’ aluminium body at right. #12 Irwin/de Klerk ‘SL73/101 and #11 Surtees/Hobbs ‘SL73/121’. Note mandatory ‘spare’ mounted atop the ‘box. The T70 standard rear bodywork was aerodynamically groundbreaking at the time by rejecting the usual fastback and ‘Ferrari ridge spoiler for a flat rear deck with a slot down the middle to provide visibility for the pilot and largely undisturbed air for the engines injection trumpets. Porsche/John Wyer famously adopted a similar configuration in evolving the 917 from its original far from satisfactory ’69 rear body to its race-winning 1970/71 configuration (Friedman)

At Le Mans the team had both ‘101’ and a new chassis ‘SL73/121’ which was fitted with a longer tail made of aluminium, the standard cars body was in fibreglass made by Specialised Mouldings. The new car was to be driven by Surtees/Hobbs, the other by Chris Irwin and Peter de Klerk.

Both cars had problems in practice caused by overheating, with the Lola mechanics looking after chassis setup claiming the engines ignition timing to be 180 degrees out. Some sources have it that the overheating was caused by the different aerodynamics of the longer tail which enclosed the engine. In addition, against Aston’s advice, Surtees negotiated a sponsorship agreement to use Marchal spark-plugs. The stage was set for the disastrous events which followed.

Before the off, Le Mans ’67. Surtees/Hobbs car in shot with the sister car behind- well down the grid after dramas in practice. Another angle on the unique for Le Mans rear body of chassis ‘SL73/121’ (Friedman)

Poor Surtees started the classic from grid 13 and then only covered 3 laps when ‘121’ was outed by a burned piston. ‘101’, the car started by Chris Irwin was back on grid 25. The drivers struggled with the car for 2.5 hours during which time the mechanics replaced a broken camshaft driveshaft, the engine lost oil pressure, overheated and finally broke a crankshaft damper.

The race was won by the Shelby American entered Ford GT Mk4 driven by the all-American crew of Dan Gurney and AJ Foyt.

Post race the Lola Astons were were returned to Slough, the ‘DP218’ engines removed and both cars re-engined with Chevrolet pushrod V8’s, the Aston experiment was over. It was clear the short term prospects of getting the engine race worthy were slim.

When the race engines were returned to AML and stripped it was found that the blocks had twisted and cracks were found in the main bearing housing. The engine went through a major redesign to strengthen the motors bottom end which prevented the launch of the Aston Martin DBS V8 road car until 1969, initially 6 cylinder variants were sold.

Surtees had this to say about the Lola Aston Martin program…

‘The Aston V8 could have achieved so much but was a total disaster. We didn’t expect to compete on out and out speed- we were hoping to a degree that weather would play a hand. If it rained a bit as it did at the Nuburgring and the Le Mans practice we were very competitive. Before Le Mans we did a long test at Goodwood, ten or twelve hours, but in the race we only lasted a few laps because Aston Martin had changed the design of the head gaskets! As soon as we got the cars back from Le Mans we took the Aston engines out and that was the end of that’.

In addition Surtees felt the T70 Mk3 chassis was inferior to his Can Am T70 Mk2 ‘I didn’t like the Mk3. The front suspension was altered and i hadn’t done any development or testing on the changes. I didn’t like the effect on the character of the car, it lacked the positiveness of the original and didn’t suit my style of driving. I didn’t mind a car being a little loose at times, but i couldn’t stand something which you couldn’t point where you wanted. Some people tried to compensate by playing with the aerodynamics, but i just stopped using the Mk3. Luckily the previous years car was still in America so we dragged that out of retirement’.

In the same MotorSport article Surtees notes the contribution of Firestone tyres to the package. He did most of the Firestone testing in the UK, with a lot of work done on springs and dampers, and working closely with Koni to keep pace with tyre development, a spin-off of the Firestone/Goodyear war of the time. ‘That brought its problems too, because as you improve the tyres you put greater stress through everything, but the car retained its user-friendly character’.

There are some contradictions in the quotes above, Surtees was a tough character, after all, despite the Lola’s shortcomings he was off the front of the grid at the Nurburgring so the chassis cannot have been too bad!

In the end the Lola Aston Martin program was one of unfulfilled promise, but David Brown was right- racing did indeed improve the breed. The rigours of competition identified design shortfalls in the original DP218 engine which were not apparent during road testing. As a consequence the modified production V8 proved to be a strong, reliable unit- and the basis of a good race engine in the decades to follow!

From Surtees perspective he had bigger fish to fry. He was juggling multiple race programs on both sides of the Atlantic with the Lola/Honda F1 exercise, Lola T100 Ford FVA F2 car and in the Can Am where Lola’s dominance was being overtaken by the ‘papaya menace’- Bruce McLaren’s M6 McLaren Chevs. John’s endurance T70 program was best advanced by bolting Chevy’s into the back of the cars in place of the Aston engines. Only a week after Le Mans Surtees ran at the front of the pack so engined at the Reims 12 Hour…before popping his Chevy engine. Unfortunately the Chevs rarely provided the reliability the T70 needed for endurance success in the blue riband events. But what a car all the same!…

1967 Endurance Season…

I wrote an article a while back about the Ferrari P4 which also profiled the main protagonists of sportscar racing in ’67- Ford Mk4, Ferrari P4 and Chaparral 2F Chev which may be of interest. The article also has photos of the Lola Astons at Le Mans.

John Surtees cruising his Lola Mk4A Climax around the Lakeside paddock during the 1963 Australian summer…

No doubt he is on the way to or from scrutineering, the Lola devoid of its usual slinky ‘Specialised Mouldings’ fibreglass body. These cars were designed by Eric Broadley as F1 machines, they were the front line weapons of the Bowmaker Racing Team during the 1962 season.

Strong results at championship level were skinny even when the too flexible spaceframe Mk4 chassis was braced with aluminium to become the ‘semi-monocoque’ Mk4A. The last of the Mk4’s was modified in this manner and is the car Surtees raced in Australasia in the summer of ’63- chassis ‘BRGP44′. The chassis made its debut in the non-championship Kanonloppet at Karlskoga in Surtees hands on 12 August 1962 and was then raced in the GP’s of Danske and Italy before being converted for Surtees’ use in the South Pacific.

The Mk4’s were fitted with both the Coventry Climax FWMV 1.5 litre V8 for F1 use and the 2.5 or 2.7 litre Coventry Climax FPF engine for the Intercontinental Formula and for Formula Libre as the Australasian summer races then were.

The global stock of FPF’s found a ready home in Australasia after the commencement of the 1.5 litre F1 as the ‘engine de jour’ in our Formula Libre, Gold Star and Tasman races until 1966 when ‘multi-cylinder’ engines arrived. The BRM P261 V8 won the Tasman in 1966 in Jackie Stewart’s hands, soon the Tasman was awash with interesting engines from BRM, Repco, Ferrari and Ford. Mind you, the good ‘ole FPF was still a contender in Gold Star events with Spencer Martin and Kevin Bartlett consistently knocking off Repco V8’s in domestic Australian events into 1967.

Surtees was on the cusp of four-wheel greatness of course. In 1964 he won the World F1 Drivers Championship for Ferrari in a Tipo 158, an additional title to match those already won on bikes.

Bowmaker Racing entered cars for John and Tony Maggs that season in Australasia achieving a good measure of success. Competition was stiff too. That year the internationals included Jack Brabham, Bruce McLaren, Graham Hill (Ferguson P99) and coming-man Chris Amon. In addition Australian and New Zealand Champions included Bib Stillwell, Lex Davison, John Youl, David McKay and Jim Palmer- not all of these blokes did the whole series mind you.

The Lakeside International was held in blistering Queensland summer heat with Surtees taking a fine win from Graham Hill and Bib Stillwell. He was first in the NZ GP at Pukekohe early in January too, having gearbox dramas at Levin and Wigram and a distant 9th at Teretonga with undisclosed problems. He then contested the Australian events at Warwick Farm, finishing 2nd in the AGP at Warwick Farm, took the win at Lakeside and then jetted home to the UK and testing duties with Ferrari. The rest, as they say is history…

Lola Mk4A ‘BRGP44’ raced on into 1963. The car was converted back into an F1 machine, the 2.7 FPF was lifted out after its sojurn in Australasia and an FWMV Coventry Climax V8 re-fitted back at Lola in Bromley. Chris Amon was allocated the car for the ’63 F1 season, although Maurice Trintignant raced it at Monaco. The cars best result that year was funnily enough Amon’s first race in it- 5th in the Glover Trophy at Goodwood.

Surtees in his big Ferrari 312, a new F1 car built to the 3 litre formula introduced that year leads Jackie Stewart in his light, nimble BRM P261, a 1.5 litre F1 car bored to around 2.1 litres and shortly to be victorious over ‘Big Johns’ heavy and not so powerful Ferrari.

It may have been different if he had driven the light, nimble Ferrari Dino 246 allocated to teammate Bandini, but that was not to be and so the pressures mounted which lead to Surtees departure from the Scuderia shortly thereafter. And with it any chance Ferrari had of winning the title that year. Brabhams year of course.

John Surtees races his North American Racing Team Ferrari 158 to second place at Watkins Glen on October 4, keeping alive his ultimately successful 1964 title chances…

Enzo Ferrari was in a spat with the Italian governing body at the time over its refusal, Ferrari having failed to build the minimum number of cars, to homologate the sports/racer Ferrari 250LM as a Sportscar. The result of which forced entrants to race it as a Prototype, a category in which it was not competitive and not designed for; putting aside the lucky, outright 250LM Le Mans win for Masten Gregory and Jochen Rindt in 1965!

Not that the Italian autocrat was going to let principle, as he saw it, get in the way of practicality. There were Grand Prix World Championships to win so rather than race in traditional racing red he ‘relinquished his entrants licence’, the cars, works cars in every way, shape and form being entered by Ferrari’s concessionaire in the US, Luigi Chinetti’s N.A.R.T at both the final two 1964 championship rounds at Watkins Glen, New York State and in Mexico City.

Surtees 2nd placings in both races gave him the Drivers title and Ferrari the Manufacturers from Graham Hill’s BRM P261 by 9 points.

‘Honour’ and title won the Ferrari’s raced on in Italian Racing Red and the 250LM as a prototype, much to its private entrants chagrin…

Barry Sheene laps Brands Hatch in a 1976/7 Surtees TS19 Ford in his first F1 drive on 25 April 1978…

It would have been interesting if Bazz gave cars a ‘red-hot’ go from about then, born in 1950 he was 28 and had already won the 1973 Formula 750 and 1976/7 500cc World Titles for Suzuki.

Not too many motor-cyclists have made the transition from bikes to cars successfully at elite level. Three spring to mind; John Surtees, Mike Hailwood and less obviously Johnny Cecotto. His speed and race wins on bikes flowed into F2 drives, badly broken legs in his Toleman Hart during 1984 British GP practice, he had already banged himself about on bikes, ended an F1 career of great promise.

image

Buckle up. At the time the Surtees TS19’s were being raced in the British F1 Series, so were ‘still current’

Sheene still had unfinished business on bikes though; always a threat when on a decent machine, he raced on in 500’s, his battles against Kenny Roberts the stuff of legend, his last win the 1981 Swedish GP.

An accident at Silverstone during 1982 British GP practice was one too many. He hit a fallen competitors obscured bike at around 160mph, slid for 150 metres, breaking both legs again, and an arm. Undimished, Sheene had enormous courage and resilience, he raced on into 1983 on a semi-works Suzuki even finishing 8th in the British GP 12 months after the awful accident. Unsurprisingly, his ultimate edge was dulled, he retired from bikes in 1984.

Barry did race touring Cars and trucks prior to emigrating from the UK to Oz in the late 1980’s, he left his beloved Britain in search of sun to help ease arthritis partially caused by his many race prangs down the years.

An immensely likable character, he was soon as popular here as in Europe mixing property development, motorsport TV coverage and commentary with product endorsements. He and Oz Touring Car Legend Dick Johnson did a series of TV ads for Shell for years which both polished its brand and were iconic in terms of their laconic humor. Sadly lost to cancer at the all-too-young age of 53 in 2003.

The much anticipated switch of the British multiple bike champion to four wheels took place when he contested the Formula Junior races at the ‘BARC Members Meeting’ at Goodwood on 19 March 1960.

Ken Tyrrell entered him in a Cooper T52 BMC, the ‘novice’ raced into second between the Team Lotus duo of Jim Clark and Trevor Taylor both mounted in Lotus 18 Fords, more competitive cars. The field also included other later GP drivers Peter Arundell and Mike Spence.

It was a great debut so why not jump into the deep end?

The Non-Championship F1 ‘Oulton Park Trophy’ took place at the Cheshire circuit on 2 April, with limited testing the talented Brit took on a field of some depth, starting the race from pole and again finishing second. Innes Ireland took the win in a Team Lotus 18 Climax with the very experienced Roy Salvadori third in another Cooper T51 Climax. The field also included Harry Schell and Chris Bristow.

The CanAm Championship morphed out of a series of professional level sports car races which had taken place for over a decade. In 1965 this comprised 4 events, 3 won by the Chaparral 2 and 1 by a Lola T70.

The first CanAm series held in 1966 was won by John Surtees in a quasi-works Lola T70; ‘Big John’ won 3 races, Dan Gurney and Mark Donohue 1 apiece in Lola T70’s as well with Phil Hill taking a race in a Chaparral 2E.

Whilst Colin Chapman designed the first ‘modern monocoque’ single-seater, the Lotus 25, which made its debut at Zandvoort in 1962, it was Eric Broadley who first applied the new construction technique to a sports-racer with his 1963 Lola Mk6 Ford.

Chapman was convinced the backbone chassis which worked so well in his Elan road would migrate to sports-racing success but the Lotus 30/40 chassis were as floppy as a centenarians todger with results reflecting same. Even Jim Clark could not make those cars sing.

So impressed were Ford with Eric’s Mk6 he was famously contracted to lead the design team of its GT40, a car with a steel tub.

The aluminium tubbed T70 was one of his first designs after his ‘Ford sabbatical’, that design process useful in terms of evolving the car Eric thought Ford should have built in the first place!

In all it’s variants the T70 remained a ‘competitive tool’ in both Group 7 (CanAm) and Group 5 World Sports Car Championship events into the dawn of the 1970’s, Teddy Pilette qualified his Team VDS Mk3B 19th at Le Mans in 1971, not bad for an old car with a pushrod OHV V8 against the might of the 5 litre, 12 cylinder Porsche 917 and Ferrari 512!

In endurance racing the T70 was really only held back by a suitable engine, the 12/24 hour longevity or lack thereof of the Chev engines usually chosen to power it. The small block Chev not having the benefit of factory investment in its development in the same way Ford’s Le Mans winning small block ‘Windsor’ V8 did.

Jim Hall made it tough for himself  in ’66/7 by chasing championships in both Europe and the US, Chaparral sought titles in both the World Sporscar Championship and the CanAm. They were always a threat with their unique blend of factory Chev engines and stunning chassis and aerodynamic innovation and quasi General Motors support.

But Bruce McLaren was the ‘dark horse’ challenger.

McLaren had been racing in US sportscar events since his Cooper days, he became more serious with the acquisition of Roger Penske’s Cooper/Zerex Special, click here for an article on that car;

https://primotipo.com/2015/03/19/roger-penske-zerex-special/

The Zerex became a test-bed for his own cars, the M1 which he raced in both the UK and US through until 1966. These spaceframe cars handled well and were very light but the aluminium Oldsmobile V8’s which provided the cars weight advantage and balance were also limited by their power; the blocks ‘maxxed out’ at about 4.5 litres so the cars gave away plenty of mumbo to those running 6 litre engines.

McLaren and Chris Amon ran Chevs in their factory M1B’s in 1966 so Bruce had clarity about the big engine and its packaging needs, the Kiwi had a clear fix on what was needed to win in the CanAm. He couldn’t match Jim Hall in terms of innovation but he could with sound design, engineering and construction of a monocoque car with a 6 litre Chev engine and simple aerodynamics, all key elements the T70 possessed and which also needed to be improved.

In essence this was the design brief McLaren gave to Robin Herd, the M6 McLaren the ’67 factory car the result. M6 started the ‘Bruce and Denny Show’ with 5 wins and Bruce deservedly taking the championship.

The dominance of the McLaren was a function of several elements. The design and execution of simple well engineered cars which arrived for the CanAm having been shaken down in the UK by Bruce and were race-ready when the short season began was key. The team comprised 2 cars and world class drivers every year. The team had a US base in Livonia, Detroit and it’s own engine program,  it’s 6 litre Chevs built by George Bartz and tuned and assembled in-house under Gary Knutsen’s supervision. Finally the team had adequate sponsorship to do things properly.

The 1968 McLaren M8 was a ‘clean sheet’ design built from the learnings of the M6; the M8B, M8D and M8F works cars of 1969/70/71 evolutions of the M8A with sufficient change to ‘stay ahead of the pack’.

The dominance of McLaren was enhanced by ex-works cars passing into the hands of the best drivers at the end of each season and customer cars available to whoever wanted one; last years works-car became this years customer car, such bolides built by Trojan Industries so the works team didn’t have to worry about pesky customers! By the end of 1968 at least, Lola’s dominance in terms of grid numbers was over.

Such was the challenge Lola, Chaparral, John Surtees, Dan Gurney and the other best team owners faced.

Eric Broadley updated the T70 into the Mk3B for 1967, Surtees and Donohue were 3rd and 4th in the Championship with John taking a win at Las Vegas at the seasons end.

The T160, Lola’s new car for 1968 was in essence a development of the T70. Surtees only raced in several rounds of the championship. Sam Posey was the best placed Lola T160 driver, finishing 9th in the drivers championship.

For Surtees it was time to do his own thing, his first customer car was the Surtees  TS5 F5000 car for 1969, in terms of the Can Am he jumped ‘out of the fat and into the flames’ Jim Hall’s 1969 Chaparral 2H not his best car. Surtees did get a taste of the M8 McLaren when Hall realised he had built a ‘clunker’ and bought an M12 customer car for John to drive whilst the team sorted the 2H, Surtees revelling in the car on the few occasions he raced it!

Commercially for Broadley the appointment of Carl Haas as the Lola importer in 1967 was an astute move and provided the base for both firms success for decades with Haas having some of the attributes above to take on the papaya McLarens in the short term.

1970 was one of the great years of the CanAm, the sound conservative engineering of the McLaren M8D juxtaposed by Jim Halls outrageous Chaparral 2J Chev, one of the most stunning, original, innovative, epic racing cars ever built. The 2 stroke engines which created the vacuum for its ground effects were its weak link and the cause of too many retirements but the car was stunningly fast whilst it lasted in Jackie Stewart’s and Vic Elfords hands.

‘The Establishment’ had it banned at the end of the season of course; ‘movable aerodynamic devices illegal’ but the CanAm lost its soul and it’s ‘unlimited nature’ in making that decision, Hall telling the organisers to ‘go jam it’ and with it the CanAm lost its biggest draw if not its most successful team.

Haas convinced Eric Broadley to design a new Lola for the 1970 season and signed Peter Revson, just peaking as a world class driver, to get the best from it.

The gorgeous, swoopy T220 was the result. The car had a very short 88 inch wheelbase which made it difficult to drive, a tyre failure at 180mph at Road Atlanta destroyed the car, but fortunately not Revson. It was a blessing in disguise as the replacement T222 had an additional 10 inches added to its wheelbase and made it a much more competitive car.

t220

Revson’s T220 at Road Atlanta and destroyed that weekend. ‘Fence’ an addition from original body spec. (Jim Hayes)

Having said that the T220 was fast if unreliable; Revvie qualified it 2nd at Road America, 3rd at Mid Ohio and 4th at Watkins Glen and Mosport, his best finish 2nd to Hulme at Mid Ohio.

With the longer wheelbase T222 he immediately banged the car on pole at Donnybrooke, finishing 3rd behind the 2 McLarens and qualified 3rd at both Laguna Seca and the final Riverside round for a 3rd and DNF respectively.

So, by the end of the year the Lola car/driver combination was close to the McLarens, Hulme took the 1970 title, Revson finished 6th.

Revson was off to McLaren for 1971, all Lola/Haas had to build was a better car, building on the base of the T222 and hire a driver of the required calibre.

Part 2: The Lola T260…

Having had a taste of the Can Am in 1970 and earlier years Jackie Stewart was keen to return, the professionalism of the Carl Haas team and Lola, a marque familiar to him having raced a T90 successfully at Indy together with Graham Hill in 1966 had appeal. He could fit the series into his 1971 F1 program with Tyrrell, or so he thought. Click here for an article on the Lola T90 and the 1966 Indy 500;

https://primotipo.com/2015/06/12/graham-hills-american-red-ball-spl-lola-t90-ford-indy-winner-1966-2/

Lola’s mount for Stewart was designated the the T260, the car was designed by Bob Marston with Eric Broadley’s guidance.

Lola Heritage; ‘The chassis was a…Lola full monocoque in L72 and NS4 light alloys bonded and riveted together with the fuel bags in either side of the tub with a total capacity of 60 gallons. The oil tank was contained in the rear of the left-hand fuel section. The rear of the monocoque extended to the back of the engine which was sandwiched between two bulkheads, a bell-housing supported the gearbox and absorbed suspension loads.

Cooling was via two brass-finned Serck radiators mounted behind the driver’s shoulder level and fed by two large NACA ducts on the top of the bodywork, the radiators vented through large louvres in the rear bodywork. Two oil coolers were mounted behind the water radiators and used the same ducts, an additional transmission cooler lay flat over the gearbox.

The bodywork was evolved following extensive tests in the Specialised Mouldings wind tunnel and featured a short, bluff nosecone with gauze-covered holes on the top to equalise pressure. At the base of the nose were two air ducts to feed air to the front discs, at the rear two ram pipes on the top of the rear body section collected the cooling air for the rear discs’.

Pete Lyons described the cars aerodynamic approach ‘The T260…was built to an aerodynamic theory already embodied in a few small-bore sports cars of the day. The intent was a shape that would bullet through the air on the straights and also remain stable as the car’s pitch attitude, ride height and positioning behind other cars changed everywhere else. In particular…a more conventional downforce-producing wedge nose, such as McLaren’s…could abruptly change from downforce to lift under certain conditions…’

t 260 aero

The front suspension on the T260 comprised unequal length wishbones, the upper ones were triangulated to form bell-cranks that operated Bilstein dampers and coil springs which lay almost horizontally across the front of the tub. The unusual spring-medium location freed space for the front brakes to be mounted inboard. Eric Broadley’s intention was to reduce the unsprung weight of the front wheels by moving the brakes inboard from their conventional hub location. This would have permitted the lighter wheel assemblies to ride better over the often bumpy CanAm circuits. Jackie Stewart was adamantly opposed to inboard brakes after the death of his close friend Jochen Rindt due to the failure of an inboard-brake driveshaft on his GP Lotus 72 at Monza in September 1970. Conventional outboard brake mountings were used on the finalized T260 instead.

A tangent is the fact that later JYS was comfortable enough with Engineer Derek Gardner’s approach to inboard front brakes, his 1973 Championship winning Tyrrell 006 being so equipped.

Rack and pinion steering was ahead of the front suspension.

Lola Heritage; ‘At the rear there was a short top link and a long radius arm attaching to the front engine bulkhead, a lower member extended rearwards to a cross-member bolted to the rear face of the gearbox. The springs and dampers fixed to the lower member and transmitted their load to tubular outriggers on the gearbox bell-housing.

Lola-made centre-lock, peg-drive magnesium wheels were fitted, their diameter 15 inches with 10.5 inch front and 17 inch wide rear Goodyears’. The battery was mounted in the nose and a Graviner onboard fire extinguisher was fitted behind the dashboard’.

Two cars were built for Haas, chassis ‘HU1’ was Stewart’s race chassis, ‘HU2’ was an unused spare  in 1971.

The engine was a 496 cu in (8.1 litres) V8 Chevrolet tuned by George Foltz, it produced circa 700 bhp and 618 lb-ft of torque, Lucas fuel injection was fitted with a Scintilla Vertex magneto and a Hewland LG600 4-speed gearbox transmitted the power.

When completed the car was tested by Lola racer/tester/development engineer Frank Gardner who was also turning his mind and skills into getting more speed from Lola’s F5000 T190/2, no doubt the F5000 was a ‘kiddy car’ compared to its 8 litre big brother!

Stewart drove the car in a rain soaked run at Silverstone prior to the cars shipping to canada for the season opening CanAm round at Mosport, Canada.

Rounds 2 and 3: St Jovite, Quebec Canada 27 June and Road Atlanta, Georgia, 11 July
The second round was at St Jovite. Stewart put the T260 on the front row next to pole sitter Hulme’s McLaren M8F. Denny led from the start but Stewart sat in second until lap 52 when Hulme, tiring from a stomach bug had to slow due to exhaustion. Stewart won the race from Denny and Revson.

Stewart recalled in an interview with Gordon Kirby ‘St Jovite was a good win because with that car, that track was hard work! The other race where we did quite well was at Road Atlanta. We led the race then had a puncture and a whole series of other problems but still turned the fastest lap of the race, quicker than Hulme’s pole time’.  Revson won the race from Hulme and Motschenbacher.

Round 4: Watkins Glen, New York, 25 July
The T260’s speed was not in doubt, it was back on pole again with Hulme and Revson right behind. Stewart got the drop putting the T260 into the lead from Revson, the Lola and McLaren diced until Stewart pitted with another puncture losing a lap while the wheel was changed.

Stewart returned to the race and began to fly setting the fastest lap but on the 56th he retired the car after detecting vibrations which proved to be a failing transmission. Revson won from Hulme and Jo Siffert in the factory Porsche 917/10.

Round 5: Mid Ohio, 22 August
Stewart, famously a successful campaigner for better circuit safety was unhappy with the track; its surface excessively bumpy and the presence of trees and telegraph poles surrounding the course meant mistakes would be punished severely.

Much overnight work was carried out to remove some of the trees and poles and add straw bales where possible but after looking at the result Stewart declared he would ‘run but he wouldn’t race’. Stewart’s position could be appreciated after the bumpy track caused 3 rear suspension failures to the T260 during qualifying.

Stewart qualified 3rd and was 2nd behind Revson at the end of lap 1 but the McLaren drew away as Stewart drove well within himself. On lap 72 Revson’s driveshaft universal joint failed (the same problem had sidelined Denny Hulme) and Stewart took the lead and race win from Siffert’s Porsche and Tony Adamowicz’ ’69 ex-works McLaren M8B Chev.

From this point on the continual development of the McLarens told whilst the Lola effort didn’t improve enough. McLaren were a well drilled team and both drivers were  experienced campaigners with whatever changes needing to be made could be done quickly in their Livonia, Detroit workshop or back at Colnbrook if necessary.

Whilst the T260 was effectively a works effort run by the marques US importer, Lola were at their core a manufacturer of customer racing cars with many customers, not a race team with only one focus.

Jackie Stewart on driving the T26o and stresses of two major campaigns, F1 with Tyrrell and the CanAm Lola in 1971…

Stewart related to Gordon Kirby and Adam Cooper in separate MotorSport magazine interview’s; ‘There were no wind tunnels in those days and Eric (Broadley) would suddenly arrive and under his arm was a new front wing. There was one we called ‘the cowcatcher’. It was hung out front of the car and what it was doing i just don’t know’

‘The car was very short wheelbase and very difficult to drive. In comparison to the McLarens, (Stewart was approached to drive for them in 1972 and actually signed to do so but withdrew when the extent of his health problems were clear) the car was just a monster to drive and we were just trying to keep up’.

‘I tested the McLaren and it was just like a passenger car compared to the incredibly nervous, pointy, short wheelbase Lola where you were a millisecond from an accident all the time.’

Stewart said the Lola T260 was the most physically demanding car he raced in his career ‘On the very fast circuits like Riverside it was awfully tricky because you never knew where you were going’. In order to make up for its shortcomings ‘I sweated more. It was just a difficult car to drive. There are some cars which are easy to drive and others not and that was one of the ones that was not’.

In a contest for the worst car he ever drove; ‘The Lola T260 CanAm car would probably make that one…the H16 BRM runs it a close second’.

The main problem was dire understeer in addition to ultimate twitchiness at speed. The Lola’s blunt nose was dotted with mesh covered holes through which the underbody air could pass. In theory this helped provide some downforce. In its initial guise the shape of the front didn’t seem to have any obvious way of providing grip. Broadley deliberately opted not to have a fashionable chisel nose. But the lack of downforce at the front was borne out by the position of the giant rear , which was usually far forward, just behind the injection trumpets  in an attempt to achieve some sort of balance.

A combination of racing around the world in 2 series and lots of promotional work gave Stewart mononucleosis. ‘I was flying back and forth from Europe to do F1, i won the world championship that year and 2 CanAm races, but i also got mononucleosis (glandular fever), a really debilitating disease that took your energy away. You couldn’t sleep and yet you were overly tired. So it was a tough year, a really exhausting year’.

stew montjuic

Its interesting to reflect on Jackie’s comments on the differences between the two cars; in fact both the T260, which retained the same wheelbase as the T222 and the ’71 McLaren M8F had 98 inch wheelbases.

The front/rear track of the Lola was 58 inches, of the M8F 60/57.75 inches. The overall length of the Lola was 139 inches compared with the much longer M8F’s 167 inches.

The aero treatment was radically different of course, a lack of downforce something the team chased progressively throughout the season.

Round 7: Donnybrooke, Minnesota
T260 had revised rear suspension but the McLarens were continually being developed as well, Stewart’s 3rd fastest time 2 seconds adrift of the factory M8F’s.

Stewart got away well and led for 2 laps until Revson found a way past, Hulme was unable to pass Jackie as the McLaren was losing grip in the Lola’s slipstream. The positions remained until lap 22 when Stewart felt something amiss and pitted, nothing could be found, he resumed in 10th a lap and a half down.

The Scot raced the T260 back to 4th but another puncture saw Stewart back in the pits, the T260 finished 6th, two laps down. Revson again won from Hulme and Gregg Young’s McLaren M8D/E Chev 3rd.

Round 8: Edmonton, Alberta Canada, 26 September
The T260 featured a revised nose shape designed to give more downforce, the rear wing was moved back to balance the new nose.

Stewart qualified 3rd again. Jackie had a great start on the wet track and led. The T260 was handling well in the rain, the Scot extended his lead over Jackie Oliver’s Shadow and Hulme’s McLaren. Stewart was still leading at half distance but a trip onto the grass when lapping Motschenbacher’s M8D lost the Lola’s handling balance.

Gradually Hulme closed the gap and he suddenly found himself in the lead with 13 laps remaining, the deteriorating handling caught Stewart out and he spun. The T260 resumed in second but with it’s competitiveness lost Stewart settled for a safe 2nd. Jackie Oliver finally got the Shadow Mk2 into the points in 3rd.

cow catcher

Round 9: Laguna Seca, California, 17 October
At Laguna Seca the T260 had lost its high downforce nose from Edmonton and now featured a huge, front ‘cow-catcher’ wing projecting out in front of the nosecone.

Stewart managed 4th on the grid behind the McLarens and David Hobbs in the Ti22 Chev.

Stewart soon passed Hobbs, David raced the Carl Haas ‘factory’ Lola T310 in 1972, and after 10 laps passed Hulme who had some broken valve springs.

Revson seemed secure 25 seconds ahead of Stewart but a collision with a backmarker required a pit stop to secure a loose door. Stewart was now 9 seconds behind. Revson started to pull away again but with 20 laps to go Revvies engine lost power, he nursed it over the remaining laps but with 2 to go the M8F was puffing blue smoke.

He drove the last two laps cautiously to win and but Stewart who took the chequered flag as Revson had been shown a black flag, Revson claimed he hadn’t seen it.

The Carl Haas team protested Revson and the results were pending for some hours but eventually Revson got the win but received a $250 fine. Hulme was 3rd.

Round 10: Riverside, California, 31 October
The series final round was at Riverside on October 30, only 3 1/2 short months since the series commenced in mid-June.

Stewart again qualified 3rd, the T260 now having bigger sideplates on its rear wing.

Hulme took the lead at the start but Stewart got up to 2nd as Revson, looking for points to clinch the Championship didn’t make it difficult. Unable to challenge Hulme Stewart was running happily in second until a piston failed in the big aluminium Chevy on lap 27.

Hulme won from Revson and Howden Ganley in the BRM P167 Chev.

The end of the 1971 Can-Am Championship resulted in Peter Revson as champion with 5 wins to Revsons 3, Stewart finished an honourable third to the two McLarens…

As Lola Heritage puts it ‘He had been their only consistent competitor over the ten rounds and there was a certain ‘what may have been’ feeling over the whole series, if only reliability had been better and punctures had been less’.

In addition to that its a shame the car hadn’t been finished earlier and tested extensively at Goodwood and Silverstone prior to crossing the Atlantic, but it wasn’t and the dominant McLaren’s reaped the rewards.
