SR4L Official BT20 league announcement + Racing Calendar

[Bruce]

Brahbam won the championship title in 1966 with the BT19 model and in 1967 with the BT20.

BT20 chassis and suspension were different from BT19, yet an evolution too.

So BT20 is a real 1967 car.

thats not correct - the bt24 was the 67 car that took all the points to win drivers and constructors - 3 wins to the lotus 49 4 wins -in 67 -but they had way more finishes in the points - hulme won with it that year - bt 20 is a 66 car - bt 24 premiered in 67 with the new repco engine - the gpl car is a bt24

I concur. Back in the day I spent many an hour with a hex editor modifying the GPL Brabham, so did a bit on research on it.

This though is from Wikipedia, The BT19 (to superseed the BT11) was designed in 1965 for the 1.5 Formula (but never raced). When the FIA increased the engine capacity limit to 3 litres the manufacturers where caught napping and nobody had a proper 3 litre car ready (in fact as late as Monaco '67 Lotus used a 2 litre engine in the Lotus 33, as the brutish Lotus 43 was not suitable around the streets. Also at least a couple of BT 11s where used with bigger engines in 1967 and Al Pease drove Gurney's 1966 Eagle in 1967, which had an overbored Climax engine), Repco had a suitable engine which was fitted to the BT19. Only one was made, and was the first car bearing the driver's name to win a champianship race.

The BT20 Was a proper 3 litre car built in 1966 and did race in the a few races in 67, Jack had the first BT24 so Denny had to use the BT20 untill his was ready. In fact he won in Monaco in it.

The BT24 was developed from an F2 car, the same concept as the BT19; put a great big reliable motor in a small light car. A concept still used today with the Rover V8 in lightweight sports cars. Interestingly the Repco and Rover V8 engines are both based on the same Aluminium Buick V8. http://www.motoringweekly.com.au/2017/10...-repco-v8/
