monaco 1958

Quite a stunning 1960 Monaco vista…

I was trawling the internet, as I do, looking for photos which inspire the articles I write, one of the reasons why this blog is so nuttily diverse is to do with that approach.

I found this shot, unattributed as most of them are, but identified as ‘Monaco 1966’ which it most definitely is not!

Its one of those the more you look, the more you see shots; the steam train, four nurses sitting together, the working port, none of your fancy-schmancy big yachts of today and of course the car itself!

That’s the tricky bit. It’s not sharp in focus but I thought it might, just might be, Luigi Musso’s #34 Ferrari Dino 246 in the 1958 race.

After I posted this shot, reader Grant Perkins did some research and confirmed the photo as Richie Ginther at Monaco in 1960 in the Ferrari Dino 246P…

Stirling Moss won the race in Rob Walker’s Lotus 18 Climax – Colin Chapman’s first championship win as a manufacturer – from Bruce McLaren’s Cooper T53 Climax and Phil Hill’s Ferrari Dino 246.

The shot is historically significant. Ginther made his GP debut that weekend and his mount, the Ferrari 246P, the Scuderia’s first mid-engined racing car, competed for the first time.

Monaco that year is also significant for the long awaited, but far too late appearance of Lance Reventlow’s Scarabs. These superbly engineered, but heavy, unwieldy front-engined cars entered GP racing just as Ferrari, the last team by then racing a front-engined car experimented with its mid-engined replacement. A tangent too far for this article, but see here; Better Late than Never… | primotipo….

scarab

Ferrari built the 246P in secret. It was tested at Modena by Hill, Ginther and factory tester Martino Severi on 22 May. The design was perceived by its drivers to have too much weight at the rear causing excessive nose lift under acceleration.

Despite Stirling Moss’ Cooper win in the 1958 Argentine GP Grand Prix, and Jack Brabham’s Cooper win in the 1959 World Championship – firsts mid-engined cars – Carlo Chiti had to fight hard to build a mid-engined Ferrari prototype.

The Scuderia’s conservatism was proven time and again over the years. They were not often innovators or early adopters. Examples include the change from drum to disc brakes, wire wheels to alloys, carburettors to fuel injection, ladder frame to spaceframe chassis, spaceframe chassis to monocoques and so on.

Fortunately 246-0008 showed enough promise to race at Monaco on 29 May. By the end of the year the chassis had morphed from a prototype 2.5-litre F1 car into a 1960 1.5-litre F2 156. It then morphed into an an F1 156 with the GP rule change from 2.5 to 1.5-litre engines with effect 1 January 1961.

0008 became Giancarlo Baghetti’s race chassis for 1961, part of the amazing start to his F1 career. The Italian famously won his first three GPs; Syracuse, Naples and finally the French GP. In so doing Giancarlo became the only man to ever win his first championship GP.

So, 0008 won the first of many GPs the 156 design took in 1961 on the way to dual world titles; the drivers for Phil Hill, and manufacturers for Ferrari in 1961.

There wasn’t a happy ending for the chassis though. Giancarlo spun out of the wet British GP at Aintree a week after his Reims win doing enough damage to 0008 that it was scrapped. Mind you, Ferrari famously destroyed all of the 156s at the end of 1962 when the cars were as uncompetitive as they had been fast the year before.

From mid-engined 2.5-litre F1 prototype at Monaco on May 6 1960 to 1.5-litre F1 winner at Syracusa on 25 April 1961, 0008’s story is a short but historically significant, interesting one.

1960 Monaco Grand Prix…

Ginther qualified the new car ninth, between the front engined Dinos of Von Trips eighth, and Phil Hill 10th. In the race Hill was third, Richie sixth with Von Trips eighth but not running at the finish.

Ginther’s new prototype mid-engined Ferrari Dino 246P-0008 #34 beside the conventional front-engined, third placed Dino 246 of Phil Hill at Monaco in 1960. The difference in size is not that great at this stage. Some sources say Ferrari acquired a Cooper to understand that car’s packaging and suspension geometry tricks (unattributed)

The team then took the 246P to Zandvoort for the following Dutch GP, however, the engine, which had not been rebuilt was burning and blowing so much oil that it was unraced.

Ginther therefore ran a conventional front-engined Dino as did his teammates. They were comprehensively blown off by large numbers of Lotuses and Coopers. Ginther’s 12th was the quickest Ferrari qualifier, with Von Trips fifth, Ginther sixth, while Phil Hill retired with engine failure on lap 13.

The race was won by Jack Brabham’s Cooper T53 Climax on the way to his second title on the trot.

(George Phillips)

Chassis Tipo 543, of welded tubular steel was described as Cooper in style if not in the quality of the welding! Borrani wire wheels were 15-inches diameter, Dunlop tyres 5.25/6.5 inches wide front/rear. The wheelbase was 2300mm and track 1200mm front and rear. Fuel capacity 150-litres, while the car’s weight, wet was 452kg.

Engine Tipo 171 was derived from the Tipo 134 65-degree, all alloy, DOHC, two valve V6. Bore/stroke 85 X 71mm, capacity 2,417cc. three Weber 42 DCN carburettors with twin plugs fired by Marelli magneto. Dry sumped, the unit developed a claimed 265bhp @ 8,300rpm.

rear sus

246-0008’s rear suspension comprised upper and lower wishbones, coil spring/Koni dampers and roll bar. The Tipo 543 transaxle had five speed and reverse and an LSD. Note also the clutch location at the back of the ‘box, you can just see the top of the inboard brake rotor beside the chassis member.

Development of the 246P and its evolution into the 156…

Ferrari decided to abandon further development of the 246P as a 2.5-litre GP car. They focused their attention on the front-engined Dinos for the balance of the season, and the future 1.5 Litre GP car for the new Formula 1.

The basis of the new 1.5-litre F1 engine was the Vittorio Jano designed 1.5-litre Dino V6 already used in Ferrari’s front engined F2 cars which first raced in 1957. Von Trips won the 1960 F2 season opening Syracuse GP in March aboard one of these cars ahead of two Coopers.

syracuse

Chiti progressively modified the engine, initially retaining the 65-degree angle but then changed it to 120 degrees.

The wide Vee angle has/had the benefit of a very low centre of gravity and rear bodywork which was as much a styling signature of the 1961 156 as its Sharknose. Definitive-spec 1961 156s raced with the 120 degree engine, but the 65 degree was also used; 0008 was always fitted with the 65-degree spec unit.

solitude

The test bed for the new engine was the 246P 0008

After the car was fitted with a revised bodywork and 1.5-litre V6, it was tested at Modena and then entered at the Tenth Solitude F2 GP, Germany on 24 July. There, Taffy von Trips belted the Porsche 718/2s, a great F2 car, on their home ground, the aristocrat lead home Hans Hermann, Jo Bonnier, Graham Hill and Dan Gurney, all aboard factory Porsches.

Further testing and development of 0008 followed. With many of the British teams punting on the Intercontinental Formula for 1961, Ferrari were developing a formidable weapon for the new 1.5 F1, the implementation of which was confirmed, much to the Brits chagrin, as they wouldn’t have competititive engines until 1962.

At the Italian Grand Prix at Monza in September, Ferrari raced 0008 in what was getting close to the 156’s definitive 1961 specification.

0008 in 1.5 litre F2 form was raced by Taffy Von Trips to fifth place fitted with an auxiliary fuel tank among the 2.5-litre GP cars.

At the Italian GP in September 1960 Ferrari ran Taffy von Trips in 246P/156 0008. Both this and the shot below show how much more svelte the car became compared its May Monaco spec. It was not as small as the best of the British cars mind you, but in 1961 the Brits were hamstrung by lack of suitable, competitive engines (Archie Smith)

Von Trips had the 1.5-litre F2 class to himself outrunning Hermann’s Porsche 718/2 by a full lap. Phil Hill won the race, it was the final GP victory for a front-engined car but it was somewhat of a hollow one.

The sneaky Italians decided race on the combined Monza road course and banking to maximise the chances of the old-tech Ferraris winning. Power was Ferrari’s only advantage over the four cylinder Coventry Climax FPF and BRM engined cars. The Brits then told the organisers to jam-it on safety grounds with most boycotting the event.

VI Gran Premio di Modena F2 1960…

0008’s final 1960 race was Ferrari’s home event at Modena on 2 October.

In the same way that Ferrari beat the Porsche’s at Solitude in July, so it was that Jo Bonnier’s Porsche beat Richie Ginther in the front-engined 156 from Taffy von Trips in the new 156 suffering from fading brakes.

Hans Hermann was fourth and Edgar Barth fifth, both also driving 718/2 Porsches.

1961 Beckons…

All of this development work on the new-fangled mid-engined concept was very successful, the 156 was the dominant GP car of 1961.

It took the Constructors Championship for Ferrari and Drivers title for Phil Hill. Let’s not forget the role 246P/156 0008 and Chiti’s development skills and prodigious work output made in that remarkable transition from the back to the front of the grid in less than 12 months.

He qualified his Jordan EJ11 Honda very well in 5th, but a lapse of judgement on Sunday, he passed a red light whilst leaving the pitlane resulted in his disqualification, seems understandable in all the circumstances.

I struggle a bit with ‘the age of adornment’ one of my sons has a ‘sleeve’ which is suboptimal as a parent but i must confess to finding little to complain about in the discretely placed butterfly in this particular case!

Eddie Jordan really added a lot of ‘fizz’ to F1 in so many ways did he not!?

Teammate Ayron Senna qualified 4th and lost 3rd when his car failed on the last lap, he was classified 4th. The race win was taken by Alain Prost in a Williams FW15C Renault.

Bob Anderson blats his Brabham BT11 past the watching crowd, its little 1.5 litre Coventry Climax V8 echoing off the Monaco buildings on his way to a very good 9th place in his self-run car…

Anderson was born in Hendon, North London to a well-to-do family on 19 May 1931.

He made his name in the 1950s as a motorcycle racer, by 1959 he was a front running competitor in the 350cc World Championship against the stars of the day including John Surtees, Mike Hailwood and Geoff Duke. He nearly won the 1958 Swedish GP, finishing inches behind Duke but he never came so close to GP victory again.

ando bike mallory

He switched to car racing aged 30 in 1961. Anderson raced a Jim Russell Lola Mk2 Ford in some early season UK Formula Junior races before doing some events in Europe in a Lotus 20 Ford entered by Henry Taylor. His results weren’t sensational but he moved to Lotus’ factory FJ team in 1962.

His best result that year was a second place in the 1962 Coupe de Salon at Monthlery behind teammate Peter Arundell, both in Lotus 22 Fords. He was also third in the 1962 Monaco FJ event also Lotus 22 Ford mounted, the race again won by Arundell. It was a first class result, on the grid that year were Mike Spence, Jo Schlesser, Alan Rees, Richard Attwood, Frank Gardner and John Love amongst dozens of other hopefuls!

Arundell pretty much won everything in FJ that year, rocketing into a Team Lotus, ’25’ GP car in 1963.

Anderson felt it was time to progess, at the start of 1963 Bob he acquired an ex-Bowmaker Team F1 Lola Mk4 Climax. He began racing as a Formula 1 privateer ‘DW Racing Enterprises’, based at Haynes, Bedfordshire comprised Bob and his French wife Marie-Edmee! Close friends David Stanbridge and Alan Brodie were important to his success and most critically George Copeland, his fulltime mechanic.

In those far away days a living could be made, sort of, with some trade support, from start and prize money as part of the European F1 Circus participating in a mix of Championship and Non-Championship (NC) Grands Prix.

Bob’s aims in his first year were to ‘cut his GP teeth’ by mainly competing in NC events taking in some Championship GP’s later in the season.

In 1963 there were 14 NC meetings, 13 of them in UK/Europe. These events were well supported by factory teams so he had his chance to ‘strut his stuff’ in fields made up of folks like him as well as seasoned professionals.

ando lola

Anderson contesting the IX Kanonloppet at Karlskoga, 1 August 1963. The Lola was 8th on aggregate off grid 6. Jim Clark won in a Lotus 25 Climax (Bruce Anderson)

He did well in the Italian events in ’63; victory at the GP of Rome at Vallelunga, admittedly in not the strongest grid of the season, 3rd in the Imola GP, 4th at Syracuse and was 6th in the ‘II GP del Mediterraneo’ at Enna-Pergusa. He was also 8th at the Solitude GP in Stuttgart.

In addition the ex-factory Lola Mk4 ‘#BRGP43’ contested UK NC meetings at Snetterton and Oulton Park. He also travelled to France to race in the Pau GP on the northern edge of the Pyrenees and to Sweden to take the grid in in the ‘9th Kanonloppet’ at Karlskoga. His transporter did plenty of miles that year!

His Championship events were at home at Brands Hatch where he was 12th having qualified 16th of 23 and at Monza where he was again 12th having qualified 18th of 28 entries.

By any objective assessment it was a strong start to GP racing. The Lola was a good choice, maybe not the fastest ‘tool in the shed’ even in 1962, but John Surtees placed second twice in it in 1962.

For 1964 he was looking for a more competitive mount.

Most of the fancied runners went out with mechanical trouble caused by the incredible bumps on the runways of the circuit, but it was a very strong performance all the same.

The Ron Tauranac designed and built Brabham spaceframe customer cars of all formulae were popular with customers in the 1960’s. Perhaps, statistically the most successful customer single seaters of that decade.

It was therefore an easy choice for Anderson to make when he needed a more competitive mount to buy one of the five BT11’s built. Three were sold to customers and 2 retained for use by the factory ‘Brabham Racing Organisation’ team. The BT11 was an evolution of the BT7 with which Dan Gurney won 2 GP’s in 1963.

So Bob had a very competitive tool for the final year’s of the 1.5 litre formula. The Lotus 25/33 was the dominant car of 1964/5, Jim Clark took his second world title in it in 1965, but the BT11 was a good, fast, reliable, robust, easy to maintain customer car.

Gurney used his BT7 during 1965 with three 3rds and two seconds to finish the title in third place. Jack changed from his BT7 to a BT11 in Germany, it was not his best season, third at Watkins Glen his best result, better was to come for him in 1966!

Heart of the matter is the ubiquitous Coventry Climax FWMV 1496cc 90 degree V8 engine. In Mk4 spec the 2 valve, DOHC, Lucas fuel injected, all alloy motor produced circa 200bhp@9750rpm. Trick 32 valve engines available to some of the factory teams in 1965 developed more but the engine was an excellent customer choice.

The gearbox was Mike Hewlands HD5, 5 speed transaxle. The cars rear suspension, typical of the period comprised a single upper link, inverted lower wishbone, coil spring/damper unit and two radius rods providing fore and aft location. Adjustable roll bars were fitted front and rear.

In 1965 Anderson’s Championship results had too many DNF’s. Highlights were qualifying 12th for the South African GP, finishing and qualifying 9th at Monaco and finishing 9th in the French GP at Clermont Ferrand.

In ’65 NC events he was 6th at Syracuse with again too many DNF’s; at Silverstone, Goodwood and Brands Hatch.

For 1966 Grand Prix racing had a new formula based around engines of no greater than 3 litres capacity, this presented a big problem for most entrants as Coventry Climax, suppliers of engines to the British teams since the late 1950’s withdrew from F1.

My detailed account of the 1966 season and related engine issues can be read by clicking on this link, rather than repeating it all again here;

Winning the 1966 World F1 Championships: Brabham BT19 Repco…

Anderson’s solution was to use the old Coventry Climax 4 cylinder FPF engine, dominant in the last years of the 2.5 GP formula in 1959 and 1960. This engine had ongoing use and development in Australasia where it was essentially the engine of choice in the Tasman Championship, an annual series of 8 races, 4 each in New Zealand and Australia in January and February.

Bob was in good company, Dan Gurney also used the 2.7 litre ‘Indy’ Climax FPF in his new for ’66, Eagle T1G until his Weslake built V12 engine was raceworthy, that engines first GP at Monza in September. In fact Anderson outqualified Dan at Reims in the ‘battle of the FPF’s, Gurney in front elsewhere the drivers met.

The conversion of his BT11 from Coventry Climax V8 to 4 cylinder FPF specification was relatively easy as Ron Tauranac built a variant of the BT11, you guessed it, the BT11A for Tasman use, selling 5 such cars in the Antipodes, competitive tools until late in the decade.

Given all of the foregoing, remember his car was already 2 years old at the start of the season, his results in this year of transition were impressive. He qualified 8th at Monaco for DNF, 10th at Brands for the British GP DNF, finished 6th at Monza having qualified 15th and qualified 14th on the Nurburgring, half way down the big grid in his little old car, again DNF.

Bob never fully left motor-cycle racing, he contested the Dutch 250 GP at Assen in June 1966, an interesting interlude in mid-season!

He was hired as a ‘safe pair of hands ‘ to provide feedback as an experienced rider to Yamaha who were developing their new 4 cylinder engined bike, the Yamaha RD05.

Anderson’s assistance was around the bikes handling, he rode to 5th, only Hailwood, Phil Read, Jim Redman and Derek Wood were head of him. Not bad for a current F1 driver and someone who had been away from bikes for a bit!

I wonder if he is the only driver/rider to race in F1 and motor-cycle GP’s in the same year? Not sure if John Surtees raced his MV and for Lotus in the same season?

Dutch GP, 24 July 1966. Anderson’s 2.7 litre Coventry Climax FPF engined Brabham BT11 with old FJ Lotus Teammate Peter Arundell on his outside in the factory Lotus 33 BRM 2 litre. Anderson qualified 14th, 1 slot ahead of Arundell, both struggling with engines well short of 3 litres. Both DNF in the race won by Jack Brabham’s Brabham BT19 Repco.

Anderson contested the French GP at Reims straight after Assen qualifing his old car 12th and finishing a fine 7th in the first race won by Jack Brabhams 3 litre Repco Brabham V8, on his way to the title that year.

In 1966 non-championship events he was 7th in the International Trophy at Silverstone and won the Rhodesian GP at Kumalo on December4.

Looked at objectively, his results deserved a factory drive, if not in F1 then certainly in sportscars. Perhaps one of you can explain why he seems to have been overlooked?

He started 1967 well having left his Brabham in South Africa that summer. He was 2nd in the Cape South Easter GP on 1 January, John Love took the win in the Cooper T79 Climax he acquired from Bruce McLaren, that car having won the Australian GP at Longford in early 1965.

Even better was 5th place in the South African GP, that year a championship round. In April he was 8th at Silverstone’s International Trophy.

Sadly, Silverstone was the Brits last race, he qualified 17th and retired on lap 67 with engine failure, Clark won the GP in a dominant performance.

Anderson missed the following German GP but was testing in the Brabham in the wet at Silverstone on 14 August prior to the Canadian Grand Prix. The car slid off the circuit and collided with a marshal’s post. He suffered serious chest and neck injuries and died later in Northampton General Hospital.

It was a sad end to a fine rider and driver with strong engineering/mechanical skills, somebody i was aware of but did not know much about. A driver who deserved a ride in a factory car methinks!?

The ‘Old Majestic circuits’ still afford talented photographers a great canvas on which to display their talent…

Spa is one of them. Sure the backgrounds aren’t as good; trees are more distant, stone walls, chateaux and so on lacking but then driver safety is paramount. The ‘snappers’ can’t get as close either, again this is a good thing as occasionally, i remember a poor bloke at Albert Park, photographers have been killed as well.

Daniel Ricciardo won this race, his third and last win in a year in which he comprehensively blew-off Sebastian Vettel. Daniel extracted the most from the complex new generation cars with their energy recovery systems incorporated in the 1.6 litre turbo-V6 mix. Petite Prix rather than Grand Prix cars?…

brabham life 2

This 1967 Life magazine was staring at me, waiting for me to pick it up in my favourite bric-a-brac store in Chapel Street, Windsor. I  was more than happy to give it a good home. It celebrates the Brabham F1 team achievements in 1967…

Articles on motor racing have never been mainstream in such global publications, of course the article has a lot of general rather than specific enthusiast interest stuff. But I thought the photos worth posting and a little of the contents.

Jack Brabham pondering setup changes. US GP 1967 (Life)

All of these photos were taken during the US Grand Prix weekend, held on 1 October at Watkins Glen.

By that stage of the season the new Lotus 49s had the consistency as well as the speed they demonstrated from debut at Zandvoort in May. Clark and Hill finished 1-2 at the Glen in the Ford Cosworth DFV engined cars.

Denny Hulme was fourth and Jack fifth. Denny won the 1967 Drivers title and Brabham the Constructors, for the second year on the trot.

Those spaceframe BT24s powered by 3-litre Repco ‘740 Series’ SOHC, between the Vee exhaust V8s were chuckable, fast, successful cars. They were still quick in Jochen Rindt’s hands early in 1968 against even more formidable opposition, despite having only 320bhp or so.

Jack was a busy boy indeed! I think at that stage he was still ‘ghosting’ a magazine column or two as well in addition to managing the relationship with engine partner Repco.

On 27 February 2005 Mark Webber did ’10 laps’ of Sydney Harbour Bridge in his Williams FW26B BMW F1 car…

Webber had just joined Williams from Jaguar and much was expected of his shift to a top team. The Harbour Bridge run promotion was part of the build up to that years AGP held at Albert Park on 6 March.

The Bridge, a critical part of Sydney’s traffic flow was closed for 5 hours for the sortie which itself took only 10 minutes, he was flagged away by New South Wales Premier, Bob Carr.

The 2004 spec, V10 engined car was based at the City end of the Bridge and went backwards and forwards between the CBD and Kirribilli, Mark flicking the car to make the ‘tight u turns’ required. The FW26, a race winning car in Juan Pablo-Montoya’s hands in 2004, was fitted with wets in deference to Sydney’s ‘moody weather’ on the day.

Webber’s two seasons with Williams were not especially successful ones although 2005, 10th in the Drivers Championship, 3rd place at Monaco his best was better than 2006 when he was 14th in the standings. The move to the nascent Red Bull team the following year was the critical move to get into an ultimately race-winning team/car. And some celebrated duels with ‘enfant-terrible’ teammate Sebastian Vettel!

Giancarlo Fisichella won the 2005 AGP, confirming the renaissance of Renault as a team, teammate Fernando Alonso won the first of his World Championships in 2005 in the 3 litre V10 Renault R25. Mark Webber qualified 3rd and finished 5th at Albert Park in a good start to the season.

Happy chappy prior to the start of the 2005 season. I always thought Williams and Webber could have and should have achieved more, the problem was the team not MW, Williams having a fall-off in competitiveness at the time. A pity. Sydneysiders may know this spot, photo taken from the Rotunda at Observatory Hill Park looking North. Webbo would have had to elbow aside a couple of wedding groups which are booked solidly back to back for ‘happy snaps’ in the warmer months. Its my old neighbourhood, i lived there for 9 years,.The Rocks, Millers Point, Barangaroo, Observatory Hill and Sydney Observatory itself all worth a good look on foot.

Jean won the race from Eugenio Castellotti in a Lancia D50 and teammate Roberto Mieres in third. de Portago was 8th and the best placed Ferrari, no factory cars were entered by the Scuderia after a poor showing at Turin a fortnight before.

Ascari had the race in hand after a great dice with Behra early but with 20 laps to go had braking problems, the Lancia mechanics did a work around which gave him brakes on the front and allowed him to finish, Jean taking a lucky win.

John Surtees Ferrari 158 leads Jo Siffert and Jim Clark, Brabham BT11 BRM and Lotus 33 Climax at the start of the 1965 Syracuse GP, Sicily April 4 1965…

Clark won the race from Surtees and Lorenzo Bandini in another Ferrari 158. A solid entry contested this non-championship GP including Mike Spence Lotus 33 Climax, Masten Gregory BRM P57 and Mike Hailwood and Innes Ireland in Lotus 25 BRM’s. What a fabulous track this must have been.

Clark was well into his very successful 1965 season, he finished a successful Australasian summer in March winning the Tasman Series in a Lotus 32B Climax, took the ‘Indy 500 in the Lotus 38 Ford in May and won the world title, his second in the Lotus 33…apart from whatever F2, touring car and sports car victories he took that year!

The event was held on a road course in Syracuse, right in the corner of the southeast of Sicily. The GP was first and last held in 1951 and 1967, the events won by Ferraris’; Luigi Villoresi’s Ferrari 375 in 1951 and Mike Parkes AND Ludovico Scarfiotti’s Ferrari 312’s dead-heating in honor of their recently killed teammate Lorenzo Bandini, who died at Monaco in 1967.

Those 400bhp cars must have been awfully quick around that track in 1967…

Mercedes Benz’ 1937 Grand Prix car was famously the most powerful racing car until the 7-8 litre Can Am aluminium Chev V8’s deployed in the early 1970’s finally exceeded its output of circa 645 bhp. It took the 1.5 litre turbo-cars of the late 1970’s for a Grand Prix car to best those numbers of 1937…

The 750 Kg formula of 1934 to 1937 created an ‘unlimited formula’ of the type only replicated by the Can Am Series of the mid-sixties to mid-seventies. The class was minimum weight based which meant the German teams of Auto Union and Mercedes Benz, bouyed by Government subsidies and rapidly advancing military technology were able to build very light and powerful cars…far more powerful than the regulators had imagined or intended!

The mid-engined, radical Auto Union ‘P wagen’ was launched in late 1933 to critical acclaim. Mercedes approach was more conventional, the W25 a front-engined car powered by a DOHC supercharged straight-eight which initially developed circa 315bhp @ 5800rpm. Suspension was all independent by wishbones and coil springs at the front and swing axles and reversed quarter elliptic springs at the rear. Hydraulic drum brakes were used. The cars won 4 Grands’ Prix and 2 Hillclimbs in 1934.

In 1935 the W25 was further developed, Rudy Caracciola won the reinstated European Championship. Tazio Nuvolari’s famous 1935 German GP win aboard his Alfa Romeo P3 the only non-German car to win a Championship GP from 1935 to 1939.

The capacity of the W25, initially 3.4 litres increased to over 4 litres developing over 400bhp. The M25 straight-8 became unreliable when enlarged to 4.7 litres and 490bhp. A 5.6 litre, 600bhp V12 was tested but the cars, the chassis shortened (becoming so small Caracciola couldn’t fit comfortably in it) and lightened became uncompetitive with reliability, engine and handling dramas, Auto Union winning many races.

After the 1936 German Grand Prix, a catastrophic home race for the team, the best placed Mercedes-Benz in 5th position, it was clear that radical changes had to be made to the Mercedes sporting organization.

Management started by looking at the structure of their racing departments, the same issues of lack of nimbleness, communication and decisiveness which have dogged bigger companies such as Ferrari and Renault in recent decades are not new.

The organization used by Mercedes in 1936 had its roots before the First World War. After the death of Hans Nibel in 1934 the central design office was managed by ex-driver Max Sailer. Under him Albert Heess and Otto Schilling were engine design chiefs with Max Wagner the chassis supremo.

Construction, assembly and testing of the cars were handled by the experimental department led by Fritz Nallinger. Jacob Krauss managed chassis construction and Otto Weber engine assembly while George Scheerer, in charge of the dynamometer section, was responsible for engine testing.

Over the years communication between the experimental department and the sporting department led by Alfred Neubauer had begun to fail. ‘Too many cooks’ springs to mind…

bob

A new technical department between the design office and the racing team was created in 1936. The Rennabteilung (racing department) took over the assembly and testing of the racing cars from the experimental department. In charge of the new department was gifted young engineer, Rudolf Uhlenhaut. He was born in London on 15 July 1906, (died 8 May 1989) his father German, his mother English. He joined Mercedes Benz in 1931 as a Munich University graduate, until 1936 Uhlenhaut had worked on passenger cars not on any of the racers.

uhlenhaut

Rudy Uhlenhaut testing a Mercedes W154 GP car at Monza in early 1938. Uhlenhaut was a race fast, analytical driver. He was entered as potential relief driver in the Le Mans campaign of 1955. W154 in early form, radiator treatment different on the cars as raced and obviously sans bonnet here. 1938 was a 3 litre supercharged/4.5 litre unsupercharged formula. Chassis essentially an SWB version of the W125 frame made possible by the use of the smaller/shorter 3 litre supercharged DOHC, 4 valve V12. Power 425-475bhp. Car dominant in 1938, Caracciola again European Champion. (Mercedes Benz)

On 12th of August 1936 the Rennabteilung tested one rebuilt 1935 car and two 1936 cars at the Nurburgring with Caracciola and Manfred von Brauchitsch the drivers. Tests included different tyres and shock absorbers. A 60kg lead weight was placed over the front suspension in an attempt to get more front grip. After two days the drivers decamped and Uhlenhaut drove the cars himself.

Rudy had never driven a racer before, even though he was used to testing road cars at high speed on the famous circuit. However, he soon settled in and proved to be an exceptionally gifted driver. Famously it has been rumoured that Uhlenhaut once went faster than Fangio at the ‘Ring during a test in the mid 50s. Whatever the case, Rudy was a talented tester and potentially a gifted racer had he the chance to strut his stuff, his wife and corporate commitments barriers to a racing career.

Uhlenhaut concluded as follows in relation to the W25’s he drove; toe-in changes caused by the old steering geometry were too big whilst suspension travel was too little making the springs bottom. The chassis was bending during braking. The experimental department had tried to solve the problems by using both hydraulic and friction dampers and harder and harder springs exacerbating the handling problems and violent kickback to the steering wheel. At the rear the attachment point for the De Dion axle could bend as much as 7-10cm during braking. Because the suspension was so stiff the wheels couldn’t follow the road. Again, famously, once during Uhlenhaut’s tests a wheel came off at high speed yet the car continued on three wheels as if nothing had happened.

After the 1936 Swiss GP ended in emphatic victory for Auto Union Uhlenhaut suggested further racing that year was pointless. So Mercedes retired from the season to focus their efforts on the 1937 car, the W125.

Uhlenhaut’s assessment of the changes required resulted in a long wheelbase car with reduced polar moment of inertia. The chassis frame was much stiffer. The front suspension was new with greater travel and much softer springs. The car had hydraulic dampers only. The gearbox was changed to a constant mesh type improving reliabilty. During the season a new suction-type supercharger that proved superior to its precursor was also fitted.

The W125 was the first of the MB GP cars to have a tubular frame; of oval section nickel chrome-molybdenum steel of 1.5mm section. 5 cross tubes braced the frame.

The independent front suspension was again by way of unequal length wishbones, 8.45 inches and 10.59 inches in size upper and lower. Coil springs were used. Both hydraulic and friction shocks were used at the front, sometimes hydraulic shocks only.

Rear suspension was De Dion tube, the 2 end halves forged and machined from a single piece of nickel chrome-molybdenum steel. Two channel section radius rods provided fore and aft location with torsion bars, 33.2 inches long and 0.67 inch wide, providing the spring medium.

Lockheed hydraulic brakes were used, they were of 2 leading shoe type, had Iurid linings with alloy shoes and drums, the latter had steel liners shrunk in.

It is perhaps indicative of preoccupations of the time with engines that about half the ‘Australian Motor Sports’ article which provided the basis of the cars technical specifications, is about the M125 straight-eight engine!

The engine, in typical MB practice was made up of 2 blocks of 4 cylinders, with a bore and stroke of 94x102mm, the engine undersquare, as was the practice of the time, giving a total capacity of 5662cc. The engine developed 645bhp at 5800rpm, the supercharger ran at twice engine speed and was pressurised at 12-14lb per inch.

In terms of the cars detailed engine design and construction;

The blocks comprised steel forged cylinders with water jackets and ports welded thereto in sheet steel. The cylinders were spigotted into the alloy, barrell shaped crankcase. The crank ran in 9 main bearings of split roller type made by SKF. Big ends were also of this type.

Pistons were provided by Mahle, conrods fully machined ‘H section’ made of nickel-chrome steel and had plain bronze bush gudgeon pins. Lubrication was by way of dry sump with a battery of gear type oil pumps and a front mounted oil radiator.

The cylinder head featured hemispherical combustion chambers with 2 inlet and 2 exhaust valves per cylinder at an included angle of 60 degrees. The exhaust valves were mercury filled for cooling. Two gear driven overhead camshafts were used, 1 plug per cylinder was fired by magneto. The heads were not detachable.

A Roots type supercharger originally blew air, in established Mercedes fashion into the carburettor but later in 1937, the blower was reconfigured to deliver the mixture in the more usual way. A twin-choke carb was used, the fuel mix a heady brew of 86% methyl alcohol, 4.4% nitro-benzol, 8.8% acetone and 0.8% sulphuric ether…who said fuel alchemy started in the 1980’s!?

A single plate dry clutch was mounted to the engine flywheel, the 4 speed gearbox, with ZF ‘slippery diff’ and final drive unit mounted to the rear crossmember.

The cars wheelbase was 9ft 2 ins and track 4ft 10ins, the W125 weighed 16.4 cwt.

The W125 proved a winner, Caracciola victorious at the German, Swiss, Italian and Hungarian Grands’ Prix giving him his second European Championship whilst Herman Lang won at Tripoli and von Brauchitsch at Monaco. The W125 was put to one side at the end of 1937, in an attempt to slow the cars down, there is nothing new in this!, the authorities mandated a 3 litre supercharged/4.5 litre unsupercharged formula for 1938/9. The chassis of the W125 evolved into that of the 1938 season W154, that car powered by a 3 litre supercharged V12 and similarly dominant.
