Surtees, Matra MS5 Cosworth SCA, Rouen 1966 (LAT)

Lordy knows how many different bikes and cars the great John Surtees drove in his lengthy career at elite level, on two and four wheels?!…

His brief Matra F2 phase was a new one on me until tripping over some of these photographs whilst researching an article on Matras.

‘Big John’ did two races for Ken Tyrrells ‘Tyrrell Racing Organisation’ in France in July 1966.

Of course he was a man who was contract free after a series of confrontations with his Scuderia Ferrari employers, which, on the balance of probability, cost the pair the 1966 F1 titles and then caused his departure from the team with whom he was champion in 1964. I wrote a feature about Surtees  a while back which covers all of that and a whole lot more.

Surtees on his way to winning the notorious 1966 Belgian GP at Spa. The first lap deluge decimated the field, the supremely brave, stupid cine-cameramen are capturing footage for ‘Grand Prix’. Surtees Ferrari 312 won from Rindt and Bandini- Cooper T81 Maser and Ferrari Dino 246 (LAT)

 

Toto Roche moves out of the way at the start of the 1966 French GP- Bandini’s Ferrari 312 is on pole with Surtees Cooper T81 Maserati alongside and out of shot to the right is Parkes in the other works Ferrari. Brabham won from Parkes and Hulme, Brabham BT20 Repco. Surtees and Bandini both DNF.

Surtees’ last race with Ferrari was the Belgian Grand Prix at Spa on 12 June- he won it. His first with Cooper, was the French Grand Prix at Reims on 3 July.

There his Cooper T81 Maserati failed to finish with problems, (a small shaft driving the mechanical fuel pump sheared on the first lap but he ‘shoved it right up’ Ferrari by popping the unfamiliar and undoubtedly less competitive car second on the grid- behind Bandini’s Ferrari 312 on pole.

In fact, as Denis Jenkinson reported in MotorSport, the time ‘was artificial and could not last, for unaided a Cooper Maserati did not seem likely to break 2:10 seconds’- the time was recorded by way of the slipstreaming efforts of Rindt and Surtees, slotting John in behind the Bandini Ferrari and getting a decent tow before the ruse was picked up by Lorenzo.

Jack Brabham won the race of course and became the first dude to win a GP in a car bearing his own name and of his own (Ron Tauranac and Jack’s Motor Racing Developments) construction.

In addition to his Ferrari F1 and Sportscar commitments Surtees successfully attacked the 1966 Can-Am championship taking the title with three wins at St Jovite, Riverside and Las Vegas aboard a Team Surtees, Lola T70 Mk2 Chev.

But apart from that, the first Can-Am round at Mont Tremblant wasn’t until 11 September, he could take on rides as he saw fit- a couple of F2 races a week apart in France suited him very nicely indeed.

Surtees was offered the ride as Jackie Stewart was badly injured in his BRM P261, Belgian GP shunt, this accident well covered here; https://primotipo.com/2015/02/13/jackie-stewart-at-surfers-paradise-speed-week-1966-brabham-bt11a-climax-and-ferrari-250lm/

Ken Tyrrell ran Coopers in F2 in 1965 (Stewart and Frank Gardner/John Surtees/Bob Bondurant/Chris Amon/Ludovico Scarfiotti- how is that for a variety of drivers in the second car! in Cooper T75 BRM P80’s) and switched to the nascent Matra marque in 1966 when he ran Jacky Ickx and Jackie Stewart as the ‘primary drivers’ in Matra MS5 Cosworth SCA 1 litre machines. That year, out of interest, the drivers when either of the above were unavailable included Surtees, Scarfiotti, Mike Spence and Hubert Hahne.

Tyrrell and Stewart surfed the Matra wave to great effect and mutual benefit of course, winning the 1969 driver and manufacturer titles in the MS80 Ford- an F1 car Stewart rated as one of the best he ever raced. That story is told here;

1966 was the year the Brabham Hondas blitzed the Euro F2 title, Jack and Denny won most of blue-riband events with the best of the Cosworth SCA’s nibbling at their Goodyears- usually the Jochen Rindt driven, Roy Winkelmann entered Brabham. The Brabham Honda story is here; https://primotipo.com/2015/07/30/xxxii-grand-prix-de-reims-f2-july-1966-1-litre-brabham-hondas/

Right from the start the Matras were regarded as jewels of cars deploying the latest in aeronautical technology applied to automotive engineering.

Surtees had at least one test at Silverstone before journeying to France, given the engineer/racers knowledge of chassis dynamics his view of the car at the time would be interesting if any of you have any first hand accounts of his view of the car?

The twenty-second GP de Reims was run over 37 laps, 307 km on the same 3 July weekend as the French F1 GP and was predictably, on this power circuit, won by Jack Brabham’s Brabham BT18 Honda from Alan Rees in a Winkelmann Brabham BT18 Cosworth SCA and then Jean-Pierre Beltoise in a works MS5 SCA.

There were a large number of MS5’s in the race, John Coomb’s BRM engined car raced by Graham Hill to eleventh, Ickx and Schlesser were non-classified in their Tyrrell Racing Organisation BRM P80 and works SCA engined cars. Rodriguez was a DNF in his works car, also BRM engined with the Surtees SCA powered car out after completing 10 laps with piston failure.

At the end of the weekend the circus decamped from Reims in the Grand Est region, the ‘unofficial capital’ of the Champagne wine growing region, to Rouen, to the West, in Upper Normandy a distance of about 285 Km.

The entry was a little smaller than the week before- 21 cars started rather than 24 cars, the Matra marque represented by five cars- works entries for Schlesser and JPB, Tyrrell cars for Ickx and Surtees and the Coombs entry for Hill.

Surtees started on row two with Graham Hill- the two Matras together, with Brabham, Hulme and Rindt up front.

JPB hit Rindt up the clacker going into the Nouveau Monde hairpin on the first lap and spread-eagled the field. Denny worked his way up to second behind Jack whilst Beltoise, sans nose, Rindt and Rees also sought to make up lost ground but JPB retired with a leaking radiator and Rindt with a wrecked Hewland.

‘With six laps to go Brabham (in the lead) failed to appear, his Honda engine having blown up, though he said his gear-lever had broke! (Crankshaft was more like it)…Hulme was just behind so he was able to take over the lead…Rodriguez had been running steadily in the Ron Harris Lotus and gaining places as the faster drivers ran into trouble and he passed Hill and Surtees to take third as the ex-Ferrari driver’s Matra-Cosworth expired and the BRM ex-World Champion struggled along in a sick Matra BRM’ wrote Denis Jenkinson.

Denny Hulme won the 46 lap 301 km race from Alan Rees’ Brabham, Pedro Rodriguez in the Ron Harris-Team Lotus, SCA engined Lotus 44, Hill who was fifth, Trevor Blokdyk in the other Harris entry Lotus 44 SCA sixth- Surtees was classified seventh falling one lap short of the distance with differential failure.

Surtees raced a Lola for the Midland Racing Partnership once in 1966 and ran a full F2 campaign in a Lola T100 Ford FVA with the change to the 1.6 litre formula from 1 January 1967.

Matra’s relentless march to F1 continued- and they achieved Formula 2 success with many race wins and Euro F2 titles for Jacky Ickx in 1967 aboard MS5 and MS7 Ford FVA, Jean-Pierre Beltoise in 1968, MS7 FVA and Johnny Servoz-Gavin in 1969 MS7 FVA.

Jackie Stewart at Silverstone during the ‘BARC 200′ Wills Trophy Euro F2 round on March 27 1967. He raced his Tyrrell MS5 Ford FVA 1.6 to 5th behind the two Winkelmann Brabham BT23 FVA’s of Rindt and Alan Rees, Surtees’ Lola T100 FVA and Bruce McLaren’s McLaren M4A FVA. The Lotus 48’s were non-classified. There was lots of depth in the 1967 F2 fields. JPB gave the new Matra MS7 its race debut at Rouen on 9 July- Ickx used both MS5 and MS7 chassis to win the Euro F2 Championship that year from Frank Gardner’s Brabham BT23 and BT23C FVA and JPB. ‘Graded driver’, Jochen Rindt did most of the winning but was not eligible for championship points

The Early Matras…

Writing about Surtees in 1966 sort of begs the question of what went before that, context is all!

Treat this as nothing more than a summary- I am just skimming the tops of the waves, this is not anything of depth but rather a bit of a teaser for a more comprehensive piece in the future on the early cars built by Matra.

 

Whilst in French, you can probably get the gist of the car specifications from the drawing above.

Matra enthusiast Gerard Gamand on The Nostalgia Forum provides useful information on the production numbers of these early Matras.

He cites 4 cars built in 1965, two each of MS1 and MS2.

The car was designed by Paul Carillo and was based on the Rene Bonnett F2 design- Matra took over the ailing concern, which became Matra Sports.

Most of you would know the Matra monocoque chassis, drawing upon aerospace techniques was fabricated in such a tight and accurate manner, ‘that fuel bag-tanks were not required as the tub was leak proof. This technique meant that lateral bracing to the tub was possible giving it a very high degree of stiffness’ f3.history.co.uk report.

Matra MS5 chassis (G Gamand)

The chassis above is identified as an MS5- the one below an F3/F2 tub bit i am not sure which. Regardless the in-build shot is interesting.

The MS2 was a ‘long chassis’ development of the MS1.

MS1 was an immediate success with most of the teams focus naturally enough on French events in 1965.

Jean-Pierre Jaussaud was first entered for the Prix de Paris at Montlhery on 23 May 1965 in an MS1, but did not arrive.

The cars baptism of fire was at the biggest international event of the year- the 29 May Monaco F3 GP won by Peter Revson’s Ron Harris entered Lotus 35 Ford Holbay.

MS1’s were entered for JPJ and Eric Offenstadt- Eric DNF’d his heat so missed the final, whilst Jaussaud was tenth in his heat and fifteenth in the final.

Jean-Pierre Beltoise took the first marque win at Reims on July 4- the ‘Coupe Internationale de Vitesse de Formula 3’ support race for the Reims F2 GP.

(Matra)

By the end of the season, JPB had taken another win at Cognac on 25 July and JPJ wins in the Coupe de Paris at Monthlery on 17 September and the Coupe de Vitesse at Albi a week later.

Together with points scored for their placings Beltoise and Jaussaud were first and second in the 1965 French F3 Championship- the nascent marque was away…

Whilst the F3 campaign continued, as Rene Bonnett was absorbed by Matra, their Djet (Jet) evolved into a Matra Djet with Matra boss Jean-Luc Lagarde hiring Bernard Boyer- French FJ Champion in 1961, to develop a prototype rallycar for the Tour de Corse, which now can perhaps be seen as the precursor of the sports prototypes which followed.

The resultant MS3/M610 was a Lotus-Ford twin-cam engined closed sportscar which used the Djet as a base but incorporated a new chassis designed by Boyer. Its frst outing was the 1965 26/27 November Criterium des Cevennes Rally driven by Phillipe Farjon and Johnny Servoz-Gavin.

These forays into Rallying continued before the 1966 racing program got underway wrote Ed McDonough in ‘Matra Sports Cars’.

The MS4/M620 was a 1966 sports prototype powered by a BRM P60 2 litre V8, the gearbox a ZF, 5-speed transaxle- a later variant was powered by a 4.7 litre Ford pushrod V8.

Designed by Jean Hebert it used a spaceframe chassis rather than the now familiar type of Matra monocoque- the BRM engine required a new clutch and 40 amp alternator. The new car was ready by November 1965 but first made its public appearance at the 1966 Le Mans test weekend in April.

For the 1966 season 12 MS5 chassis were made- 6 each to F3 and F2 specifications.

The build for 1967 totalled 6 cars. Three each MS6 F3 and  MS7 F2. The MS6 was a modified version of the MS5 with wheel and suspension geometry changes to take advantage of the latest in tyre developments

In 1968 a further four MS7’s were built, all were F2 cars built to accept the ‘class standard’ 1.6 litre 210bhp Ford Cosworth FVA engine.

The MS8/M630 was a 1967 BRM V8 engined Group 6 sports-racer coupe.

Many of the cars mentioned in this listing were raced by Johnny Servoz-Gavin, so check out my article on him for photographs; https://primotipo.com/2016/09/02/johnnys-talbot/

Stewart, Clark, Rindt, Surtees Kyalami 1968. Matra MS9 Ford, Lotus 49 Ford, Brabham BT24 Repco and Honda RA300. Its somehat poignant in its majesty- if that is the right word to describe the busy scene of South African enthusiasts thronging this magnificent, challenging racetrack. Clark took his last championship GP win that weekend, his very last was the Tasman Formula, Australian Grand Prix at Sandown Park on 25 February aboard a Lotus 49 Ford DFW 2.5- he won a ripper of a race of 105 miles prevailing over Chris Amon’s Ferrari Dino 246T by one tenth of a second. Clark won in South Africa from teammate Hill and Rindt. Stewart retired after completing 43 laps with conrod failure from grid 3 (LAT)

It may be a tangent too far, but the first F1 Matra, the 1968 Ford Cosworth engined MS9 raced by Tyrrell/Jackie Stewart as a ‘whoosh-bonk’, to use the Bruce McLaren words to describe a quick lash-up, stop-gap early 1968 car used a modified F2 MS7 chassis- with suspension from the MS630 sportscar and a Hewland DG300 gearbox. That car, in brief, is covered in the Matra MS80 article linked above.

For the sake of completeness I also wrote a couple of articles about the MS120 F1 cars here; https://primotipo.com/2014/07/06/venetia-day-and-the-1970-matra-ms120/

Keith Duckworth on his Cosworth SCA 1 litre F2 engine…

Lets get back to where we started, the Matra MS5- in particular the engine which powered the Surtees chassis.

‘It might not have been right, but we had to make it work. It won the F2 Championships of 1964 and 1965…and…until the Honda engine of 1966 with four valves and twin overhead camshafts, tungsten carbide rockers and torsion bar valve springs appeared in Jack Brabham’s cars. We’d run out of breathing at 11,000 rpm so we obviously needed more valve area. That’s what started me thinking about 4-valve heads’.

‘Mike Costin  and I exercised great ingenuity- we had ports that curved around, we had the piston of the week with every kind of shape, dint and odd hole- but the combustion was not good, the mixture never burned properly’.

All the same, the dominant F2 engine of 1964 and 1965 did rather well producing between 115 bhp @ 8700 rpm in its original Weber 40 IDF carburettor form and in ultimate 1966 spec, Lucas injected form, 143 bhp.

Good ole Ford 5 bearing 116E block. Single, (train of seven gears) gear driven overhead camshaft, two valves per cylinder , Cosworth rods and pistons, Laystall steel crank. 997cc- 81mm x 48.35mm bore-stroke.

SCB variant 1498cc 175 bhp – 3 engines only built including the Brabham BT21B raced by ex-Brabham mechanic Bob Ilich in Western Australia

SCC variant 1098cc 135 bhp for North American sportscar racing
