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.


Brabham

Jack Brabham's "Brabham Racing Organisation" had commissioned "Repco" to build a 3 litre V8 loosely based on an alloy Buick engine. Mounted in the new light and nimble BT19 chassis the combination would go on to win the 1966 World Championship.
Although not the most powerful in the field it proved to be a most reliable contender. A later BT20 fitted with the same engine was campaigned by Brabham's team mate Denny Hulme.
Team Brabham also ran a BT11 chassis fitted with a 2.5 lt 4 cylinder Climax engine for Hulme in the first few races of the 1966 season.
"DW Racing Enterprises" ran a similar but privately entered BT11 powered by a longer stroke 2.7 lt 4 cylinder Climax engine in the hands of their driver Bob Anderson.
A third BT11 chassis was also campaigned by David Bridges Racing and Rob Walker teams. This car was powered by a high revving BRM 2 litre V8.
