3 Replies

After the disappointments of the Ford Indy derived V8 and Serenissima V8 used in the 1966 McLaren M2B, the interim BRM V8 Formula 2 based McLaren M4B and BRM V12 powered M5A of 1967 Bruce Mclaren bought 5 Ford Cosworth DFV motors for the 1968 season which were used as in the integral structure of the McLaren M7A designed by Robin Herd, Gordon Coppuck and Bruce himself.

The M7A’s and 3 derivatives, M7B, M7C, and Alfa Romeo powered M7D were entered by the works team from 1968 to 1970. For 1968 the works Formula One McLaren’s were sponsored  by Shell while the McLaren Can Am Cars were sponsored by Gulf.

Reigning World Champion Denny Hulme left Brabham to join McLaren in 1968 and on the M7A’s debut at the non Championship Race of Champions at Brands Hatch Bruce came first and team mate Denny Third. The M7A’s came in first and second at the non Championship International Trophy at Silverstone with Denny Hulme came edging the team founder.

On their third championship appearance, after Spain and Monaco, Bruce McLaren became the second man to win a Grand Prix bearing his own name crossing the line first to win the 1968 Belgian Grand Prix. It would prove to be his forth and final Grand Prix victory.

Denny Hulme won the Italian and Canadian Grand Prix towards the end of the season and finished third in the World Drivers Championship behind Graham Hill and Jackie Stewart, Bruce finished fifth in points standings. McLaren finished second in the constructors Championship behind Lotus but ahead of the Ken Tyrrell entered Matra driven by Jackie Stewart all three constructors used Ford Cosworth DFV motors.

In 1969 Bruce only drove an M7A in South Africa where he finished fifth before focusing on the M7C, which will be the subject of a future blog, which featured a more substantial monocoque. Denny meanwhile continued driving the M7A throughout the 1969 season winning the season finale in Mexico. Denny finished the season 6th in points with Bruce 3rd, the Mclaren team finished 4th and last of the Ford Cosworth DFV powered teams in the constructors championship.

The M7B fitted with outrigged panier fuel tanks made only one works championship appearance at the 1969 South African Grand Prix where Bruce Mclaren finished 5th. He later sold the car to Colin Crabbe who’s Antique Automobiles team entered it in four races for Vic Elford who finished a best fifth in the 1969 Dutch Grand Prix.

In 1970 McLaren adapted an M7 to take a non stressed Alfa Romeo V8 which became known as the M7D the car recorded three DNQ’s, did not qualify, a not classified finish in France and a DNS, did not start, in the 1970 British Grand Prix. After the first four events Nanni Galli took over the M7D from Andrea de Adamich, recording the cars third DNQ at the Italian Grand Prix.

Privately entered M7A were driven in three races by Dan Gurney for All American Racers in 1968, best finish forth in the US Grand Prix, and Basil van Rooyen for Team Lawson in the 1969 South African Grand Prix where he retired with brake problems after completing 12 laps.

06/07/13 Errata as Tim has pointed out below Bruce finished the 1960 season second in the World Drivers Championship and so his 3rd place in points in 1969 did not equal his career best as originally stated. Apologies for any confusion.

After winning three World Drivers Championships two with Cooper in 1959 and 1960 and one with his own Brabham Team in 1966 Jack Brabham decided he was going to sell up and retire at the end of 1969. He got as far as selling the team to his partner the Australian designer/engineer Ron Tauranac in 1969 but after Jochen Rindt elected to stay with the Lotus team for 1970 Jack Brabham drove for the team in 1970 before hanging up his helmet with his team placed 4th in the constructors championship.

The following season Ron ran the Brabham team with Graham Hill and Tim Schenken scoring a non championship race win with Graham Hill and a few points in the championship. Ron decided that he needed a business partner to continue and ended up selling the team to a former racer sometime team owner and driver manager called Bernie Ecclestone. It soon become clear that both Ecclestone and Tauranac liked things done their was and so Ron left early in 1972.

For the 1972 season Graham Hill was still the number one driver with Argentinian Carlos Reutemann and Wilson Fittipaldi, brother of 1972 World Champion Emerson, driving second and third string entries.For the second year running Brabham finished 9th in the constructors championship last of the point’s scorers.

For 1973 South African Gordon Murray was given the responsibility of coming up with the Brabham team’s new challenger and he came up with the Brabham BT42 built around a monocoque that unusually, for the time, featured a triangular cross section as seen seen in these photographs.

Carlos Reutemann and and Wilson Fittipaldi were the teams front line drivers being joined on occasion by Andrea de Adamich until he broke his legs in an accident on the opening lap of the British Grand Prix, Andrea was replaced by Rolf Stommelen and then John Watson in the final Grand Prix of the season at Watkins Glen.

Reutemann managed six points paying finishes with the best being two thirds in the 1973 French and US Grand Prix while Andrea, in an older 1972 Brabham BT37, and Wilson added another 6 points between them all of which moved Brabham back up to 4th in the World Constructors championship.

This particular chassis is the sixth and final Brabham BT42 built it first appeared in the 1973 Austrian Grand Prix as a replacement for the chassis damaged in the accident at the 1973 British GP. Rolf Stommelen drove the car three times qualifying a best 12th in Italy and finishing a best 12th in Italy and Canada. John Watson qualified the car 24th for the US Grand Prix but the engine did not go the race distance.

Bernie Ecclestone sold chassis #BT42/6 and BT42/5 to Martino Finotto for the 1974 season, Finotto a seasoned sports car racer realised he was out of his depth in Formula One and so arranged for fellow sportscar racers Swiss Silvio Moser, 1973 and ’74 Le Mans winner Gérard Larrousse, Austrian Helmut Koenigg and Italian Carlo Facetti to drive the cars in several European Grand Prix.

In the end only Gérard Larrousse made a start in the car, having qualified 28th for the 1974 Belgian Grand Prix he retired with tyre issues. When Gérard unsuccessfully tried to qualify the car at the 1974 French Grand Prix it carried a particularly hideous airbox as can be seen in this linked image.
