Tyre Contract For Sale – Spirit Cosworth 101D

Leave a Reply

There is no room for sentimentality in sport even if one has designed a triple Indy 500 winning Indy Car and a car that has secured one constructors World Championship and two world drivers championships after 4 year of steady decline to the bottom of the top ten one must expect ones sponsors to either walk or agree a merger with an up and coming team.

Such was the situation Gordon Coppuck found himself in at McLaren at the end of the 1980 season when sponsors Phillip Morris agreed to fund a merger between the upstart Project Four hither to Formula Two team headed by former Brabham mechanic Ron Dennis and McLaren who had not won a race since the Japanese Grand Prix in 1977.

Part of the deal would include Ron hiring John Barnard to design a new car with a fully composite chassis leaving Gordon little alternative to seek employment else where. Gordon joined his former colleague and McLaren employee Robin Herd at March for 1982 and after a year there became a founding member of a new Formula 2 team with March Formula 2 team manager John Wickham which was funded by Philip Morris and was to be powered by potent 2 litre Honda V6 engines with Belgian Thierry Boutsen and Swede Stefan Johansson as drivers.

Thierry won three races and finished third in the 1982 F2 championship behind March BMW drivers Corrado Fabi and Johnny Cecotto but more importantly for the Spirit team they had outscored the similarly powered Ralts of Kenny Acheson and Dr Jonathon Palmer so that when Honda was deciding on which team to partner in their planned for 1983 entry into Formula One it was easy to go with Spirit.

Withdrawing completely from Formula 2, having won the championship with Geoff Lees in 1981, Honda developed it’s turbocharged 1.5 litre V6 engine while Spirit adapted one of it’s Formula 2 chassis to take the engine while simultaneously working on today’s featured design the 101 from scratch.

Spirit entered a limited programme of six races mid way through the 1983 season and Stefan Johansson managed to qualify the adapted Formula 2 201 and later 201C for all the races entered retiring from three of them and finishing a season best 7th in Holland. The 101 was ready for the last two of this programme but was left unraced.

For 1984 the team had hoped to retain the Honda Engines and attract 1972 and 1974 World Champion Emerson Fittipaldi out of retirement, but Honda decided to go with the more established Williams team who had the slightly younger 1982 World Champion Keke Rosberg already on their books.

Wickham and Coppuck wasted little time and did a deal to run the 4 cylinder turbocharged Hart 415T engines, that had hitherto been developed exclusively with Toleman since 1980 and Spirit adapted the unraced 101 in time for Emerson to test before the season got underway.

Emerson decided that this was not what he really wanted and so Mauro Baldi was entered for the first six races of the season scoring 8th places finishes in South Africa and San Marino before Huub Rothengatter was entered for the next eight races. With Hart motors in short supply Huub failed to qualify with a Cosworth DFV installed in Detroit but finished a best 8th in the Italian Grand Prix at Monza on his final start in the car.

Mauro returned to the seat for the final two races of the 1984 season finishing 8th in the European Grand Prix at Brands Hatch.

For 1985 Mauro was retained to drive the 101, now in D spec with longer side pods, as was a supply of Hart engines and Pirelli tyres, which would become significant because fellow Hart powered team Toleman had switched from Pirelli to Michelin part way through the 1984 season and when Michelin withdrew from Formula One at the end of 1981 neither Goodyear or Pirelli were prepared to step in and supply tyres to the team.

Without tyres Toleman had to withdraw from the first three races of the 1985 season while Mauro could do no better than qualify 24th for the first two races of the season, after qualifying last at San Marino nearly 10 seconds off the pace and posting it’s third consecutive retirement Spirit decided to call it a day and sold their contract for a supply of Pirelli Tyres to Toleman who could do no better than post one 12th and one 14th place finish all season though Teo Fabi did qualify on pole in Germany which helped secure the teams take over by sponsor Benetton at the end of the season.

Mark Williams is seen at the wheel of the 101D powered by a Cosworth DFV motor at Silverstone Classic a couple of years ago.

’73 Chassis ’74 Body ’75 Paint – Brabham Cosworth BT42 #BT42/3

Leave a Reply

Today’s featured Brabham BT42 chassis #BT42/3 was completed in time for Carlos Reutemann to compete in the 1973 Spanish Grand Prix where he retired with drive shaft failure.

During the remainder of the 1973 season Carlos drove #BT42/3 to two season high 3rd place finishes in France and the United States which with four other points paying finishes helped him secure 7th in the final Championship standings.

Brabham Cosworth BT42, Goodwood Festival of Speed,

After finishing 4th in the 1973 constructors championship Gordon Murray set out to improve on his Brabham BT42 design with a new car, the BT44, that kept the same overall dimensions but was built with a strengthened chassis, more sophisticated rising rate front suspension and tidier bodywork.

Carlos Reutemann nearly won the 1974 season opening Argentinian Grand Prix retiring out of fuel from the lead on the the BT44’s debut, he also briefly led the Brazilian Grand Prix before winning the South African Grand Prix and latter adding victories in Austria and the United States, where team mate Carlos Pace finished second, to secure 6th in the drivers championship while Brabham rose to 5th in the constructors championship.

Meanwhile #BT42/3 was retained as a spare by Brabham for the opening two races of 1974 before appearing at non championship Race of Champions and International Trophy covered in the newer BT44 body work for the teams second driver rookie Richard Robarts to drive.

Richard who had already failed to impress team owner Bernie Ecclestone with his speed in Argentina and Brazil finished the two non championship events in 12th and 15th places respectively before being fired in favour of Liechtenstein’s Rikky von Opel of the car manufacturing dynasty.

At the 1974 Belgian Grand Prix Brabham ran #BT42/3 for Teddy Pilette who finished his one off race with the team 18th from 27th on the grid.

Ricky like Richard also failed to impress Brabham’s management with his speed in five races leading up to the 1974 French Grand Prix the second event in which he had failed to qualify his Brabham BT44.

John Goldie Racing decided run #BT42/3 for Surtees refugee Carlos Pace in France, Carlos also failed to qualify, but made enough of an impression to be promoted to the Brabham works second seat for the remainder of the season while Ricky called time on his brief Formula One career.

Two weeks later Lella Lombardi unsuccessfully attempted to qualify #BT42/3 for the British Grand Prix while at the end of the season Canadian Eppie Weitzes completed 33 laps of the Canadian Grand Prix from 26th on the grid before retiring with an engine problem on the cars final in period appearance.

Brabham Cosworth BT42, Manfredo Rossi di Montelera, Silverstone Classic,

For 1975 Martini sponsored the Brabham team which ran B spec BT44’s and despite the Carlos’s each only winning one race, Pace in Brazil and Reutemann in Germany, improved reliability meant Reutemann finished 3rd in the drivers Championship, while Brabham rose to 2nd in the Constructors Championship.

The self effacing Manfredo Rossi di Montelera, of the Martini & Rossi dynasty, is seen driving #BT42/3 at a couple of recent Silverstone Classic events in these photographs, the most recent of which can be seen from an on board camera on this linked video clip.

Increased Unsprung Weight – Tyrrell Cosworth 007

Leave a Reply

With the retirement of Jackie Stewart and the untimely death of his team mate Francois Cevert the Tyrrell Racing Organisation started the 1974 with two new drivers Patrick Depailler who had made two starts for the team as a third driver in 1972 and Jody Scheckter, who took the seat originally destined for Gerry Birrell and then Roger Williamson both of whom were killed after Jackie Stewart had told Ken Tyrrell of his decision to retire early in 1973.

With two relatively inexperienced drivers coming into the team Derek Gardner opted to design a much simpler car with a longer wheel base, all round inboard brakes and a chisel nose than the Tyrrell 006 with which Jackie and Francoise had so much success in 1973.

Tyrrell Cosworth 007, Donington Park Museum

Jody drove the #007/1 to two victories in Sweden, where Patrick was a season high second and at Brands Hatch in 1974.

Jody had an outside shot at the title at the beginning of the season finale 1974 US Grand Prix where he retired with a fuel system issue having secured third place in the championship.

Tyrrell Cosworth 007, Donington Park Museum

For 1975 the design of the 007 was revised with the radiators being angled back on the vertical plane dispensing with the need for side pods to house them and with outboard front brakes being adopted which adversely affected the unsprung weight of the car.

By now Ferrari were really hitting their stride and Jody managed just the one win at his home South African grand prix which when backed up with a second place finish in Belgium, third in Britain and 6th at Watkins Glen added up to a disappointing distant 7th in the championship.

Tyrrell Cosworth 007, Donington Park Museum

On the plus side while the performance and reliability of the 007’s was tanking Derek Gardener was working on one of Formula Ones more spectacular curiosities for the 1976 season.

At the time of writing I am not sure which of two possible 007’s today’s featured car seen at the Donington Park Museum, is. I believe it is, or was, owned by American Jeffrey Lewis, it is possible that it is either #007/7 which was unraced in period or #007/4, which was built in 1974 for Patrick and converted to the 1975 spec by TRO for Patrick to race in 1975, both of which appear to presently belong to Americans.

Having seen a 007 a few years ago in the Scuderia Gulf Rondini colours for whom Alessandro Pesenti-Rossi drove #007/4 in 1976 I suspect today’s featured car is most likely #007/7, if you know different please do not hesitate to chime in below.

Pole Sitter & Sister – Shadow Cosworth DN5 #DN5/1A #DN5/2A

1 Reply

Things were looking up for reigning Can Am Champions Don Nichols Shadow team in 1975, the Can Am series folded, but the team kept a strong US presence with a Dodge powered DN6 Formula 5000 team which used a similar Tony Southgate designed chassis to today’s featured DN5 design.

Following the dominant trend in F1 design the DN5 was built around a slimmer lower monocoque, than the previous years DN3, but with a longer and wider wheel base and track than many.

Shadow DN5, Silverstone Classic,

Jean Pierre Jarier put the DN5 #DN5/1A, seen here in the first third and sixth photographs at Silverstone Classic 2013, on pole on the cars debut in Argentina, but the car never started having stripped the crown wheel and pinion in the gearbox on the warm up lap.

Jumper was on pole again at the 1975 Brazilian Grand Prix, but retired seven laps short of the finish after the fuel metering unit failed.

Shadow DN5, Donington Park Museum,

The non championship Race of Champions at Brands Hatch saw the DN5’s run with a new TV test card like colour scheme and Tom qualified the sister #DN5/2A, seen in the close ups at Donington Park Museum, on pole and then ran away with the race while Jean Pierre finished 4 laps down from 3rd on the grid classified 8th with a fuel pump issue.

Further highlights of the season came in Spain where JPJ finished a season high 4th from 10th on the grid and at Monaco where still driving the two original chassis Tom and JPJ qualified 2nd and 3rd respectively, but both retired with accident damage which would be the final appearance of JPJ’s #DN5 1A.

At the British Grand Prix run at Silverstone Tom won his only career championship pole but retired after an opening lap accident, by now having scored two 6th place finishes in Belgium and Holland.

Shadow DN5, Silverstone Classic,

In Germany Tom still driving #DN5/2A converted 16th on the grid to a fourth place finish.

Meanwhile keen to find another engine supplier the similar Shadow DN7 with a V12 Matra engine, which I looked at a couple of weeks ago, had been built up for JPJ to drive in Austria and Italy.

Shadow DN5, Donington Park Museum,

While the Matra proved not to be quite the fillip to the team’s fortunes that were anticipated Tom drove #DN5/2A to the teams season high 3rd place finish in Austria from 15th on the grid.

At the non championship Swiss Grand Prix run at Dijon in France JPJ was once again on pole with the Cosworth powered #DN5/4A, Jumper looked like he was going to break his F1 duck, until the 34th lap from 60 when the transmission broke and he retired from the lead.

Shadow DN5, Donington Park Museum,

At the Italian Grand Prix Tom once again drove through the field coming home 6th from 14th on the grid.

#DN5/2A’s final appearance came at the 1975 US Grand Prix where Tom qualified 7th but finished unclassified 7 laps down.

Shadow DN5, Silverstone Classic,

Having failed to convince Matra of their suitability as a partner for the 1976 season Shadow also lost their sponsor UOP meaning Tony Southgates new Shadow DN8 was put on hold while the team continued running the DN5’s in B spec, which I shall look at next year, that was introduced to meet new regulations from the Spanish Grand Prix.

Pursuing The Unfair Advantage – Penske Cosworth PC3

Leave a Reply

After Mark Donohue drove his Penske PC1 to a 5th place finish in the 1975 Swedish Grand Prix Roger Penske, forever pursuing an unfair advantage, gave Geoff Ferris the go ahead to build a new car and ordered a March 751 for Mark to drive in the interim.

Penske PC3, Silverstone Classic

Mark finished 5th from 15th on the grid in the March on it’s debut at the 1975 British Grand Prix, retired with a damaged tyre on lap 1 of the German Grand Prix and then succumbed to injuries received from an accident during practice for the Austrian Grand Prix.

Penske PC3, Silverstone Classic

Skipping the Italian Grand Prix Penske returned to the fray at the 1975 United States with today’s featured car the Penske PC3 chassis #PC3/01 and John Watson as his new driver.

Penske PC3, Chris Drake, Silverstone Classic

With it’s shovel nose the 3 litre / 183 cui Cosworth V8 powered PC3 bears some resemblance to the March 751 which Mark crashed in Austria however it retained the rear suspension layout of the PC1, and was, aside from it’s tall airbox, fully compliant with new regulations that would be mandated from May 1976.

Penske PC3, Silverstone Classic, Press Day,

John qualified 12th for the 1975 US Grand Prix, but after a misfire was detected swapped over to take the start of the race in the older PC1 in which he finished 9th.

Penske PC3, Silverstone Classic, Press Day,

#PC3/01 was raced on four occasions in 1976 with John scoring the models best finish in South Africa with a fifth place finish from 3rd on the grid.

Penske PC3, Silverstone Classic

But even as the team was celebrating it’s improved qualifying form Geoff was working away on the new PC4 which made it’s debut at the 1976 Swedish Grand Prix.

Unlike #PC3/01 the second PC3 #PC3/02, in which John retired from each of his three starts, was immediately sold on and had a second career in the 1976 and 1977 British Shellsport Group 8 Championships, Derek Bell drove the car to a win at Oulton Park in April 1977.

Today’s featured car is seen at a recent Silverstone Classic meeting with Chris Drake at the wheel.

Not Quite A GT – Ligier Cosworth JS2 #2379 72 03

Leave a Reply

In 1970 former international rugby player and construction magnate Guy Ligier set about founding a sports car manufacturing company bearing his own name.

The original production model was to be the JS2 with a chassis designed by Michel Tetu, who would later be part of the Renault Le Mans and Formula One campaigns and a body designed by Pietro Frua.

The JS2 was originally intended to be powered by a 2.6 litre / 158 cui Ford Cologne V6 but that had to be changed to the 3 litre / 183 cui Maserati V6 as used in the Merak and Citroën SM, when Ford thought it might build a rival in the form of the Ford GT70.

Ligier JS2, Goodwood, Festival of Speed,

Production of the JS2 never reached sufficient numbers for the sporting authorities to consider the car for GT racing so instead racing versions were run as prototypes.

The racing JS2’s were built with aluminium chassis and raced with Maserati V6 engines which proved a tad underpowered and unreliable, although the teams perseverance was rewarded with a victory in the 1974 Le Mans 4 hour race for Guy Chasseuil and in the 1974 Tour de France Automobile where Gérard Larrousse, Jean-Pierre Nicolas and Johnny Rives drove the winning JS2.

A second place finish for today’s featured chassis #2379 72 03 driven by Bernard Darniche and Jacques Jaubert emphasised the team’s mastery of the 1974 mixed discipline event.

Ligier JS2, Goodwood, Festival of Speed,

With new sponsorship from Gitanes for 1975 Ligier exploited the Prototype regulations more fully by producing a silhouette JS2 body and fitting more powerful Ford Cosworth DFV motors to two of his three JS2 racing cars including today’s featured chassis.

The two DFV powered JS2s were sent to Mugello and Dijon netting a 7th for Jean-Pierre Beltoise and Jean-Pierre Jarier at the former and 6th for François Migault and Jean-Pierre Jarier at the latter.

Perhaps mindful of wanting to preserve their machinery for Le Mans only single car entries were sent to Monza and Spa where Beltoise and Jarrier finished 21st from 7th on the grid and François Migault and Jean-Louis Lafosse finished 12th from 5th on the grid respectively.

Ligier JS2, Goodwood, Festival of Speed,

At Le Mans the two DFV powered JS2’s were joined by a third Maserati powered JS2 the latter to be driven by Beltoise and Jarier.

Unsurprisingly the Maserati was slowest of the three starting from 9th it was also the first of the three to retire after an accident.

Today’s featured car driven by Henri Pescarolo and François Migault qualified 5th but retired later in the race with a puncture.

The second DFV powered JS2 driven by Jean-Louis Lafosse and Guy Chasseuil qualified an impressive 3rd and survived to finish second only one lap down behind the Gulf GR8 shared by Derek Bell and Jacky Ickx.

After Le Mans 1975 Ligier retired from sports car racing in preparation for it Gitanes sponsored appearance in Formula One the following season.

Spare Smallman Embassy – Lola T370 #HU3

Leave a Reply

At the end of his relatively unsuccessful, season high 9th place finish in Belgium, 1973 season at the wheel of his privately entered Embassy Shadow DN1, Graham Hill hooked up with Lola, who’s car he had driven to win the 1966 Indy 500, for a two car attack on the 1974 World Drivers Championship.

Lola T370, Haynes International Motor Museum

Embassy sponsored the building of the Lola T370 which was designed by Andy Smallman. Unlike Lola T330 and T332 Formula A/5000 cars with rear mounted side radiators the T370 had the radiators mounted directly behind the front wheels, as would appear on Lola 1975 T400 Formula A/5000 car.

The most remarkable thing about the T370 when it first appeared was the outsize tall airbox which gave the car the appearance of a sail boat, much larger than the one seen in today’s photo as can be seen in this link.

Graham’s efforts with the T370 were rewarded by a 6th place finish in the Swedish Grand Prix, but apart from that the over weight if reliable T370 was not particularly competitive as drivers of the second car; Guy Edwards, Rolf Stommelen, Peter Gethin and Vern Schuppan found out.

Guy Edwards scored a best 7th behind his team mate in the 1974 Swedish Grand Prix and German Rolf Stommelen repeated the feat in the 1975 South African Grand Prix.

Today’s featured chassis HU3, seen at the Haynes International Motor Museum, first appeared as a spare car at the 1974 Spanish Grand Prix a role it remained in for 11 of the 14 events to which it was taken.

The car was first raced by Peter Gethin in the 1974 British Grand Prix where he qualified 21st on the grid but retired with a puncture. Rolf Stommelen then drove the car in the 1975 Argentine and Brazilian Grand Prix where he started 19th and 23rd on the grid respectively and finished 13th and 14th respectively.

HU3’s final appearance was again with Rolf at the wheel during practice for the 1975 Italian Grand Prix at Monza.

The T370 was superseded by a single T371 chassis in 1975 but as it dawned on Graham it was time to retire he decided to follow the lead of 3 time World Champion Jack Brabham and 2 time race winner Bruce McLaren to become a Formula One constructor.
