Some cars leave a paper trail; the Lola T300 left a name and a place in Lola Cars's list. What follows is what can be said with a source behind it. The shape is credited to Eric Broadley.
Where it came from
The Lola T300 was an open-wheel formula race car, designed, developed and built by Lola Cars, for Formula 5000 racing, in 1971.
Under the skin
the output is 510 hp. On the scales it comes to 1360 lb. That is roughly 375 horsepower per tonne: genuine supercar pace. The wheelbase is 2563 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
In context
Nearby in the Lola Cars catalogue sit the Hill GH1 and the Lola B02/50.
