The January 07 issue of Evo has a very interesting multi-car track shootout. For the past few years Evo has been using the West Circuit of the Bedford Autodrome to benchmark track performance. This is how the best laps stacked up:
Radical SR3 1300 1:17.10
Caterham R500 Evo 1:19.00
Ariel Atom 1:19.60
Caterham CSR 260 1:19.60
Dax Rush MC 1:19.70
Porsche Carrera GT 1:20.20
McLaren F1 1:21.20 (aftermarket wheel & tire package and exhaust)
Ferrari Enzo 1:21.30
Litchfiled Type-25 1:22.25 (415hp modified STi on r-compound tires)
Lotus Exige S 1:22.40
Ford GT 1:22.75

The lightweight trackday specials still have the edge over the big power supercars. Speaking of supercars, I was impressed that the McLaren F1 managed to lap marginally quicker than the Enzo despite heavy steering, big oversteer tendencies, and brakes described as "shite".

For comparison, here are some lap times from previous tests:
Lamborghini Gallardo '06 1:22.80
Porsche 997 Turbo 1:23.55
Ferrari F430 1:24.20
Corvette C6 Z06 1:24.45
BMW M6 1:26.40
Porsche Cayman S 1:26.85

 

radicals are amazing!!!! great lil rig.
thanks nice post

 

Litchfiled sti is awsome too, I saw a clip on it. I like how they left it 100% stock looking under the hood.

Ford GT is last place behind a Exige S

Wish there were more cars that we can buy in the states in the test such as GT3 and Z06/Viper
