Some cars leave a paper trail; the Lotus 96T left a name and a place in Lotus's list. What follows is what can be said with a source behind it. The shape is credited to Gérard Ducarouge.
Where it came from
The Lotus type 96T was Team Lotus's last Indycar. The project was the brainchild of former Formula 2 team owner Roy Winkelmann. During the 1960s Winkelmann had proved successful running Brabhams and scoring successes with Jochen Rindt. However this team was to break up suddenly in 1969 with some of the core personnel (including Alan Rees) forming March Engineering. Winkelmann then relocated himself in the United States and built up a large and diverse business empire. Following the creation of the CART series in 1979 Winkelmann saw a perceived blossoming of international interest and was once again lured to an opportunity to race again. However he did not wish to buy an "off-the-shelf" March or Lola chassis as was de rigueur in CART racing during the 1980s.
Instead he initially approached Cosworth and obtained some assurances that they would be prepared to build "works" engines for his team. All teams in the championship were effectively running second-hand DFX engines at this point, with little input from Cosworth. Winkelmann then approached Team Lotus and their new designer Gérard Ducarouge to obtain a bespoke chassis with the plan of competing and conquering CART within three years. Ducarouge enlisted Mike Coughlan to help design the chassis. The 96T was Ducarouge's response to these requirements. Its tub, lines and suspension were similar to the Lotus 95T that was racing in the 1984 Formula One Championships, but with one significant design alteration. Ducarouge had foreseen that at a track like Indianapolis, the car stood the very real possibility of hitting a concrete
In context
In the Lotus line-up the Lotus 96T has a clear place: it replaced the Lotus 64. Nearby in the Lotus catalogue sit the Lotus 100T and the Lotus 101.
