For the 1986 season, Riccardo Patrese returned to Brabham, and was joined by Elio de Angelis. The season was a disaster for Brabham, scoring only two points. Murray's radical long and low BT55, with its BMW M12 engine tilted over to improve its aerodynamics and lower its centre of gravity, had severe reliability issues, and the Pirelli tyres performed poorly. De Angelis became the Formula One team's only fatality when he died in a testing accident at the Paul Ricard circuit. Derek Warwick, who replaced de Angelis, was close to scoring two points for fifth in the British Grand Prix, but a problem on the last lap dropped him out of the points.
