Audi TT

Audi is launching an all-new version of its TT sports car. The 2007 Audi TT, which debuts in Europe this year, doesn't hit U.S. showrooms until early in 2007, first in coupe form and then later as a roadster.
When it was launched in 1998, the Audi TT was hailed as an icon of automotive design, with the 2+2 sports coupe's flowing lines cloaking an athletic chassis and responsive family of powertrains. As difficult as it might be to improve an icon, Audi seems to have done so with its new TT.

The completely new TT carries on the "circles and domes" design language that distinguished the first generation, but it's now 5 inches longer and about 3 inches wider than its predecessor and features numerous technical improvements.
Among those technical improvements is the extensive use of aluminum in the car's structure, which not only reduces power-robbing weight but provides more strength than a conventional steel configuration. Steel components are used in the rear of the car to help provide balanced weight distribution and enhance the handling.
