BT49C is th Brabham BT49 specification for 1981 Formula One season. The basic model, BT49, was constructed by Gordon Murray in 1979 and was used in several modifications until 1982. The most significant feature of BT49C was a hydropneumatic suspension system for the BT49C in which soft air springs supported the car at the regulation height for checks while stationary. At speed, where the ride height could not be measured, downforce compressed the air and the car settled to a much lower height, creating more downforce. Nelson Piquet on BT49C with hydropneumatic suspension set pole position at the Brazilian and Argentine Grands Prix and win the Argentine and San Marino races. In next 11 races of the Championship Piquet won only once at round 10 in Germany and his main rival Carlos Reutemann driving Williams FW07C took the leadership in the Driver’s Championship. But at the final race of the season the Caesars Palace Grand Prix in Las Vegas Reutemann starting from pol position managed to finish only 8th while Piquet finished 5th scoring 2 points and took the title from Argentinian by one point.
