The MP4/2 was designed by John Barnard for the 1984 F1 season. For 1985, the car was updated to MP4/2B with cleaner aerodynamics and redesigned wings. In accordance with revised regulations a smaller rear wing was fitted and the suspension was modified to accommodate for the switch from Michelin to Goodyear rubber. Porsche refined the TAG engine with improved power (850 bhp in race and 960 bhp in qualifying) and fuel consumption. The revised machine was as competitive as original MP4/2 as Prost won the opening round of the new season. The competition had gotten stronger and Lauda in particular struggled. Prost won five races and it was enough to win his first driver’s title and McLaren again bagged the constructor’s crown. Lauda, in his last season, took one victory winning Dutch Grand Prix at Zandvoort.
