It wasn't until the year 2000 that Audi brought a roadster to the North American market. It was called the TT, and it was based on VW's compact A4 platform. Initially equipped with a turbocharged 1.8L 4-cylinder engine, the 222hp was sent to all four wheels courtesy of Audi's Quattro all wheel drive system. Slight tweaks over the next few years would lower the curb weight from around 3,200 lbs. to just over 3,000 lbs, and power would increase thanks to a newer more powerful 1.8L engine or an optional 3.2L V6. These improvements were heralded by drivers, and improved the TT's standing in the roadster market. The next generation was really where the Audi TT started to shine, and a whole new list of Audi TT Quattro parts replaced the ones from the previous model years. During this generation, Audi also introduced the Clubsport Quattro concept to fans at the 2008 Wￃﾶrthersee Tour in Austria producing nearly 300hp from a 2.0L turbocharged 4-cylinder engine - though Audi has not committed to any level of mass production. Fun fact: the "TT" comes from the line of NSU (once a German car manufacturer, purchased by VW and now known as Audi) cars such as the 1000TT, 1200TT, and TTS.
