Thank you very much again for this fine documentary about Lotus and the Ford Cosworth DFV.

This link gives race reports as they appeared in Motorsport during 1967.
1966
New Formula introduced. There was widespread use of uprated 1.5 litre machinery until the new generation of 3.0 Litre engines became available.
1967
Focused around engine performance, the Repco 3.0 litre V8 in the lightweight Brabham chassis took the Championship while the 3.0 litre Cosworth-Ford set new standards. Aerodynamics were already in the minds of some, Brabham and Lotus both used spoilers at Spa and a ‘bubble cockpit canopy and gearbox shroud was used at Monza by Brabham.
1968
The Cosworth-Ford 3.0 litre DFV, made available for customers and fitted to McLaren, Matra and Lotus cars dominated the results. Wings were introduced at Spa on the Brabham and Ferrari but were developed rapidly by Lotus. Firestone YB11 tyres worked well but engine power outstripped available traction making way for some to plan four-wheel drive concepts.
1969
A 500Kg minimum weight limit was introduced to allow for the new onboard fire extinguisher and revised roll over bar requirement. At Barcelona strutted wing failures lead to a hasty application of new low, chassis mounted wing restrictions. The Cosworth engine dominated in the Tyrrell Matra. Four-wheel drive was tested and abandoned.
1970
The end of the spaceframe era in F1, aircraft style bag tanks were made mandatory and subsequently monocoques. The weight limit was set at 1530Lbs (695Kg). Lotus introduced engine induction air boxes and Matra introduced the trend to use high airboxes. The Lotus 72 dominated and the flat-twelve Ferrari made its mark.
