Top 10 Cars of the 2013 Frankfurt Motor Show

6. Audi Sport Quattro Concept

A hefty monster to say the least, Audi pulled the cloth from its Sport Quattro concept in Frankfurt. The car is like yellow hellfire with a plug-in hybrid drivetrain and a bit of a beer gut if you consider the 4,078-lb curb weight.

Get around that enormous number and you’ll see a stunning car. Its chunky, carved proportions create an aggressive look that hides a surprisingly functional cabin. There are four usable bucket seats, all being pulled by a 4.0-liter twin-turbo V8 mated to a hybrid drivetrain that makes a grand total of 700 hp.
