The Lola T900 is one of the Lola Cars entries the open record knows by name, and by little else. That is not nothing: a name in the catalogue is where a car's story starts to be recoverable.
The background
The Lola T900 is an open-wheel racing car chassis, designed and built by Lola Cars that competed in the CART open-wheel racing series, for competition in the 1985 IndyCar season. It won a total of 5 races that season, with Al Unser Jr. taking 2 wins, and Mario Andretti taking 3 wins, while narrowly missing out on another win at that year's Indianapolis 500. It was powered by the 800 hp (600 kW) Ford-Cosworth DFX.
The engineering
800 hp is the published figure. It weighs 1550 lb. Work it out per tonne and you get about 516 horsepower — hypercar territory, where the limiting factor is the tyre, not the engine. The wheelbase is 3048 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Where it sits
Its family tree is legible: it took over from the Lola T800; its successor was the Lola T86/00. Its Lola Cars stablemates include the Hill GH1 and the Lola B02/50.
