 The 99T was generally regarded as the more bulky of the cars that won a Grand Prix in 1987 with the Williams FW11B, McLaren MP4/3 and Ferrari F1/87 all regarded as better aerodynamically than the Lotus.Despite this, the 99T (especially in Senna's hands) was often among the fastest cars in a straight line.After pre-season testing at the Jacarepaguá Circuit in Rio, Senna had insisted on the team using the active suspension throughout the season, feeling that due to having the previous year's engine the computer-controlled system and its benefits would help keep Lotus at the front of the field (one of those benefits was that due to less tyre wear, the 99Ts were able to run less wing thus giving greater top speed).
