Cool cars from the Frankfurt Motor Show

These are some of the more interesting new cars and concepts unveiled at Germany's International Auto Show.

Audi Nanuk Quattro Concept

Audi claims this sporty crossover concept can get from zero to over 60 miles an hour in just 3.8 seconds and that should get about 30 miles to a gallon. This is thanks, in large part, to an efficient 5.0-liter diesel V10 engine that puts out 544 horsepower and an impressive 738 foot-pounds of torque. As with cars from Audi's sister brand, Lamborghini, the engine is visible under a glass cover.

The Nanuk was designed by the firm Italdesign Giugiaro which had unveiled something very similar, on its own, at the Geneva Motor Show in March
