The Brabham BT20 was a very successful car in 1966 and the first part of 1967. The car features a Repco powered V8 engine, powering the lightweight car to the 1966 Formula One championship. In 1966, the car reached the podium 5 times in the season, and helped secure Brabham’s Constructor Championship.
The latest update for the rFactor 2 BT20 features some of the latest tech advancements for the sim, including the “UltraChassis”, which accurately simulates flex in the car’s chassis. The car also features the new steering system, like what was put in the Skip Barber Formula 2000’s latest update. For an added list of what has been improved, check out the changelog below.
Also, check out the video I did, getting to take a look at an early release of the car! I’d like to thank Tim Wheatley and ISI for letting me take a look at the car. Have you taken the Brabham BT20 for a spin yet? What are your thoughts? Let us know!
