Since its first introduction back in 1998, the TT has scored legions of fans. While never as powerful as the Porsche Boxster (one of its main competitors), it no doubt has the quirkiness factor. Currently in its second generation, the TT features Fuel Stratified Injection (FSI) technology. What's unique about this is it not only improves fuel efficiency, but also adds power and cleaner emissions.

Available with either a 6-speed manual or S-tronic, the TT delivers the goods. With a choice of two inline four cylinder engines - a 1.4 or 2.0-liter Turbocharged Fuel Stratified Injection (TFSI) - speed is not an issue. The 2.0-liter can go from zero to sixty in 5.6 seconds with a top speed of 150 mph. Also available in roadster form, the Audi TT shows that good things come in small packages.
