The Lola T800 was a single-seater racing car built in 1984 for the CART series.
The single-seater was powered by a Cosworth turbo engine and driven by Mario Andretti and Danny Sullivan. From the first victory of Andretti in Meadowlands, he and Sullivan won eight times in a row with Andretti winning five raced and Sullivan winning the other three.
At the most important race of the year, the 500-mile race in Indianapolis, the two drivers did not win. The winner Rick Mears drove a March 87C.
Andretti secured the CART championship in 1984 with the T800.
