Some cars leave a paper trail; the Lola B06/51 left a name and a place in Lola Cars's list. What follows is what can be said with a source behind it.
The story
The Lola B06/51, also known as the Lola FN06, is an open-wheel formula racing car, designed, developed and built by Lola for the Japanese Formula Nippon championship series, in 2006.
What is underneath
500-550 hp is the published figure. It weighs 666 kg. Work it out per tonne and you get about 751 horsepower — hypercar territory, where the limiting factor is the tyre, not the engine. The wheelbase is 3000 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Its place in the line
Its family tree is legible: it took over from the Lola B03/51; its successor was the Swift FN09. Nearby in the Lola Cars catalogue sit the Hill GH1 and the Lola B02/50.
