The 1966 Season

Hailed as the "return to power" the 1966 season saw the start of the new 3 litre formula.
Some teams were more ready than others and as a consequence a wide variety of engines and chassis were used ranging from Ferrari's new purpose built 3 litre V12 (312) to modified 65 season engines which were bored out to 2 litres.
There were also various 4 cylinder Climax engines plus a 2.4 litre V6 (246) Ferrari based on the "Dino" engine.


Colin Chapman's "Team Lotus" was another team without a 3 litre engine so they were forced to use last year's Climax V8 modified and bored out to 2 litres. This was fitted into the Lotus 33 chassis also from the 1965 season.
Eventually a deal was done with BRM to use the H16 engine which was fitted into the all new Lotus 43 chassis but unfortunately the Lotus Team suffered the same fate as BRM with this complex and overweight engine which rarely finished a race.
One exception to this was the United States Grand Prix at Watkins Glen where Jim Clark who was Chapman's number one driver managed to hold the car together long enough to cross the line in first place giving the H16 its only win in 1966.
Lotus also supplied cars to privateer "Reg Parnell Racing" who entered a Lotus 33 chassis powered by a BRM 2 litre V8 and driven by Mike Spence.
