- In this clip from Motorsport.tv's The Flying Lap, Peter Windsor revisits the build up to the victorious debut of the Ford Cosworth DFV engine that changed F1 forever when it arrived on the scene with Jim Clark and the Lotus 49 at the Dutch GP in 1967. Former Lotus and Cosworth engineer Dick Scammell recalls the frantic work required to get the engine ready in time for an unforgettable weekend at Zandvoort.

Keith was an absolute genius. His insight into engineering was amazing. Whenever I spoke to him I came away thinking I knew nothing!
Hiya mate
Unfortunately I didn’t meet my grandad (Charlie Day) some people called him Len
White man with 1 boy 2 girls with a Jamaican lady
If anyone remembers or worked with my Grandad at Cosworth i would love to know more
Much appreciated
The stuff legends are made of! Keith Duckworth said that the way you work out how powerful an engine is. The size of the 'bang', multiplied by the amount of 'bangs' that you can get into a minute... Utter perfection!
I could watch videos like this all day. Thanks for uploading!
The debut win for the Cosworth DFV in the Lotus 49/Chassis R2 at Zandvoort, Dutch GP, 4th Juin 1967, was inextricably linked with this man:
JIM CLARK - By far the greatest driver ever - no doubt. He is and was "The Best of the Best" (Fangio, Senna, Prost, Stewart and countless others about Clark). No other driver in history until today was so superior as Clark - No other driver as so much "Grand Slam" - Pole/Win/Fastest Lap/Leading every lap of the race - like him. And all that from just 72 starts... !
This man is the Olymp of driving - the Michelangelo of racing - a dynamic art at the highest level. So smooth, so precise, so fast....simply out of this world. One, who won in Spa by 5 minutes (!) in monsoon rain with only one hand at the wheel (!) because of gearbox trouble...One, who takes back a complete lap (!) in Monza and back into the lead... One, who took pole on the original 22,8 km Nürburgring track by 9 (!) seconds and more....One who won Indy by 2 whole (!) laps...
In 1965 he had the most succesful year of a driver in the history of the sport: He won the F1 World Championship, the Tasman Series with F1 cars, the Indy 500, the British and French F2 Championship, the British Touring car Championship, totally over 50 (!) victories in one season !!!! For eternity and by lightyears unmatched in the sport. That`s just some examples of his mesmeric unique genius...
The implementation of a quill shaft in the timing gear assembly was brilliant. Had cryogenic treatment been understood at that time I could imagine Duckworth trying it.
Walt Disney was using it in 1966,.....🤷♂️
Way back in the days when NBC here in America infrequently covered Formula One, I remember Colin Chapman being interviewed at the Dutch GP, I think. When asked Lotuses future engine plans, he replied, " if we can get our own engine for '67, we'll run BRM's for '66. If we can't get out own engine for '67 we'll quit". I suspect he already had Cosworth signed up, so this was just posturing.
starman1968ful All that happened way before my time but amazing how smart but down to earth all those guys were. You don't see stuff like that today. Also we need coverage like this in the States. Mention Ford and F1 in the same sentence to any guy in their mustang and all of a reply you get is "huh". Ha
The only Mustang owner I know has a Cosworth DFV valve cover hanging on his wall.
Great history piece. Do wish they were still powering cars, but then, we won't go down that road...
Awesome vid!
The common response is that the quill drive was genius solution.
I have never felt the same about that.
Keith was faced with a serious harmonics problem which he couldn't sort out.
The quill drive solution was just a band aid repair from my perspective,as it was allowing undesirable flex in the valve gear drivtrain to absorb the harmonics,which effectively makes the valve timing less accurate.
The harmonics should have been correctly cotrolled by weighted valve drive components,given time and budget.
Then along came the Cosworth GMA.
In simple terms Keith was an engineering genius.
Turning a gear drive to,in effect in one way,a chain drive.
