Just seen the results from the Dijon race the weekend before last: Klaas Zwart was driving the Jaguar R5 and won by 59.361s over a 1997 Benetton in the first race. It was only 19 laps so he was over three seconds per lap faster!
Zwart’s best lap of 1’04.876 was a new lap record, beating Alain Prost’s 1’05.257 from 1984:

In an interesting field, the next cars across the line were a Dallara GP2 (first generation), Panoz DP01 (Champ Car 2007), a World Series by Renault Dallara and a G-Force IndyCar. Results and schedule here:

Also, one of the drivers competes under the pseudonym ‘Luke Skywalker’. Which is the best fake name I’ve seen at a race track since ‘Giancarlo Gofastio’.
Incidentally, Zwart is the guy who created the Ascari race resort in Spain which has copies of several famous corners from tracks around the world.
