Denny’s South African Office…
Cockpit shot of Denny Hulme’s second placed – Jack won in his Brabham BT33 – McLaren M14A Ford during the March 7, 1970 South African Grand Prix weekend at Kyalami.
Smiths instruments of course: the chronometric-tach telltale is on 10,100rpm, the DFV developed all of its punch from 8-10000. Oil pressure and temperature is the priority, fuel pressure and water temperature secondary and out of Hulme’s direct line of sight. Switches are for the rev limiter, ignition, electrical fuel pump (starting only) and the starter button. I’ve always liked a nice big ignition kill switch, but let’s not get picky.
The M14A was an evolution of Robin Herd and Bruce’s 1968 M7 design. A profitable Grand Prix winning design, not to forget the McLaren M10A and M10B F5000 cars which made McLaren and Trojan Cars plenty of dollars.
The cars had a few steerers in 1970: Bruce and Denny, then Dan Gurney after Bruce’s fatal Goodwood accident, and after that, Peter Gethin when conflicting oil company sponsorship contracts got in the way of Dan’s F1 and Can-Am McLaren drives.
Gurney’s qualifying best was a second adrift of Denny in the British GP, it would have been interesting to see if he could have got back his old Grand Prix race-pace had he finished the season with McLaren. He was right on-the-money in the Can-Am Cup mind you, winning the first two races at Mosport and St Joliet from pole in his M8D Chev – no doubt relishing the very first ultra competitive Can-Am car he had ever raced! – and qualified second on the grid at Watkins Glen, then faded with undisclosed dramas in his last race for the team.
There is no such thing as an ugly Papaya McLaren! Note the full monocoque aluminium chassis under that inspection hatch.
In a very tough year for the team, Bruce’s best was second place in the Spanish GP in M14A/1, and Dan’s best in three Grands Prix with that car, was sixth in the French at Clermont Ferrand.
Denny raced M14A/2 to second at Kyalami, and third in the Race of Champions at Brands Hatch and the German Grand Prix. He missed the Belgian and Dutch GPs after burning his hands at Indianapolis when an imperfectly secured quick-release cap on his McLaren M15 Offy leaked methanol and caught fire.
Peter Gethin then raced M14A/2, placing second in the Spring Trophy at Oulton Park and in the International Trophy at Silverstone.
M14A/3 became Peter Gethin’s car from the 1970 Italian GP until the Spanish in March 1971. In eight meetings his best was sixth in the Canadian GP at Mont Tremblant.
Ultimately the M14A fell a bit short in 1970, while noting again the mitigating factors. It was a rare GP season in which victories were spread far and wide amongst the Lotus 72 Ford, Ferrari 312B, Brabham BT33 Ford, BRM P153 and March 701 Ford! Jochen Rindt posthumously won the drivers title and Lotus the constructors.
Hey you in the Big Banger…
No it’s not a single-seat M8 Can-Am car, in 1969 McLaren converted M7A/3 to ‘Lancia D50 spec’ by placing all the fuel centrally and low. By filling in the space between the wheels Bruce and Gordon Coppuck were also playing with the aerodynamics of the car; the car was then tagged M7B/3.
It didn’t work though, after racing the car on debut in the South African GP at Kyalami in January 1969, and then the Brands Hatch Race of Champions (above) the car was sold to Colin Crabbe, of Antique Automobiles, for Vic Elford to drive.
Vic was fifth in the French GP, then sixth in the British before crashing it at the Nurburgring in an accident not of his making. Mario Andretti crash-landed his Lotus 63 Ford 4WD and Vic collected one of its wheels, flipped and ploughed into the trees destroying the car and breaking his arm in three places. I guess the Ford DFV and Hewland DG300 gearbox from that car found their way into the new March 701 that Crabbe bought for Ronnie Peterson to race in 1970?
Bruce drove a new car, M7C/1 for the rest of 1969. The major factor which enhanced this cars performance was the use of a full monocoque aluminium chassis derived from the M10A F5000 car, itself derived from the bathtub-monocoque M7A.
McLaren’s conventional 2WD cars didn’t get as much love as they otherwise would have in 1969 given the attention lavished upon their 4WD brother, the M9A. McLaren, together with Lotus, Matra and Cosworth pursued this blind-alley. Ultimately, very quickly, wings and the tyre company Polymer Chemists solved the ‘3-litre problem’ of too much power and too little grip far more cost-effectively than then complex mechanical 4WD mechanisms.
Bruce’s 1969 M7C – as we have seen, a lineal descendant of the 1968 M7A – begat the 1970 M14A. The major advances from M7C to M14A were inboard rear brakes, new front uprights and a smidge greater fuel capacity.

Etcetera…
A few more shots of the wideboy McLaren M7B Ford during that March 16, Race of Champions weekend at Brands Hatch in 1969.
High wings were the rage but Lotuses ‘cavalier’ engineering of their wing supports and their repeated failures – the last straw the breakages of Rindt’s and Hill’s wings and resultant crashes of their Lotus 49s at Montjuïc – saw them banned during the Monaco GP weekend that year. More tightly controlled, they stayed.
The photographs in this article demonstrate the changes being made by the teams to adapt in a a period of about 12 months, not to forget the related 4WD adventures for the affected teams!

Our pit-babe was at Clermont during the 1970 French GP weekend, the cars are Denny and Dan’s M14As and Andrea de Adamich’s M14D Alfa Romeo. Another of Rainer Schlegelmilch’s signature shots!
