High Quality Content by WIKIPEDIA articles! The Lotus 101 was Team Lotus s entry for the 1989 Formula One season. Gérard Ducarouge s departure during 1988 had necessitated the former Williams aerodynamicist Frank Dernie to be appointed as Technical Director in November 1988. Despite his appointment the majority of the work for the 101 had been conducted by chief designer Mike Coughlan. The 101 was to be a rushed design built within weeks and to a series of constraints. Durcarogue s departure coincided with end of the 1,500 cc turbocharged era. Lotus, along with other competitors, now had to incorporate 3,500 cc normally aspirated engines into their cars. Judd were therefore enlisted to supply their CV 32 valve V8 engine, but as Lotus were only a customer (Judd s principal contact was the supply of their latest EV V8 engine to the March team) solutions were sought to make up the power deficiency by appointing Tickford to research and develop a five-valve-per- cylinder head.
