Laptimes and comments:
Viper SRT10:1:15.59
As the miles passed, the Viper's true calling became clear: This beast is a better weekend toy than an everyday supercar.
997TT :1:17.17
The Turbo may well be the quickest, most practical supercar in the world. At $122,900 and up, it’s also one of the most expensive.
Z06 :1:15.74
But when you consider the price, performance and practicality of the Z06, it truly is America’s everyday supercar.
R8 :1:15.69
Still, even factoring in the Audi’s six-figure price tag, this was the one car we all wanted in our own garages. The Audi R8 may be the new supercar benchmark.
