TCC’s Bottom Line

The 2015 Audi R8 is a supercar fit for daily driving, thanks to its German precision and Italian powerplant.

The 2015 Mercedes-Benz SLS AMG GT is the last of the current line, but it still promises to be a top-level super sports car.

TCC Likes

Gorgeous from almost every angle
Thriling V-10

Gullwinged icon

Sounds great, handles well

TCC Dislikes

Limited cargo space
Entry and exit are tough
Rearward visibility is poor

Tight cabin
Trunk is shallow, can get hot
Gas mileage unimpressive even for performance
