 The modified MP4/8B, painted white with no sponsorship logos other than Goodyear, took three months to re-engineer and stretch in order to fit the longer and heavier engine (the V12 was badged as Chrysler for the McLaren tests).After first driving the car Senna suggested to the engine's designer, former long-time Ferrari engineer Mauro Forghieri, that it would be better with a less brutal top end and a much fatter mid-range.Forghieri, who had enormous respect for the triple World Champion and valued his opinion, made the requested changes.
