Some cars leave a paper trail; the Lola T61 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 T61 was an open-wheel Formula Two racing car, designed, developed, and built by British manufacturer Lola Cars in 1966. The Lola T61 was a greatly improved version of the 1965 Lola T60. The car was built for the British Midland Racing Partnership Formula Two team.
The season was marked by the superiority of the Brabham racing cars, which started with either Honda or Cosworth engines and won all the races of the year. The Lola T61 and the new Matra racing cars filled the starting fields. Fourth place for David Hobbs in the Formula 2 race in Barcelona in 1966 remained the best finish for a T61 in this racing class.
Under the skin
the output is 120 hp. On the scales it comes to 420 kg. That is roughly 286 horsepower per tonne: genuine supercar pace. The wheelbase is 88 in. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
