Brabham BT49

History

Born in weeks when Brabham dumped Alfa Romeo's V12 mid-1979, the BT49 mated Murray's ground-effect chassis to the trusty DFV and immediately flew: Piquet's first win came at Long Beach 1980, and the BT49C of 1981 — with its infamous hydropneumatic suspension lowering the car past the 6 cm ride-height rule once at speed — carried him to the title by a point over Reutemann at Las Vegas.

The evolutions tell the era's arms-race story: BT49B gearbox experiments, the C's rule-bending suspension, the 1982 D with lightweight tubs and water-ballast 'brake cooling' — Murray and Ecclestone probing every regulatory seam while turbos massed on the horizon. Piquet and Patrese kept winning into 1982 before the BMW turbo BT50 took over.

Historic racing rates the BT49 among the DFV era's ultimate drives: Masters Historic F1's ground-effect class front-runners include the type, several genuine chassis race actively, and the combination — championship provenance, Murray design DNA, standard Cosworth-Hewland running gear under severe ground-effect loads — defines the serious end of pre-'86 historic F1 ownership.
