context_page_description: The Audi TT is a 2-door production sports car made by Audi since 1998, and currently in its third generation. The first two generations were assembled by the Audi subsidiary Audi Hungaria Motor Kft. in Győr, Hungary, using bodyshells manufactured and painted at Audi's Ingolstadt plant and parts made entirely by the Hungarian factory for the third generation.
  For each of its three generations, the TT has been available as a 2+2 coupé and as a two-seater roadster employing consecutive generations of the Volkswagen Group A platform, starting with the A4. As a result of this platform-sharing, the Audi TT has identical powertrain and suspension layouts as its related platform-mates; including a front-mounted transversely oriented engine, front-wheel drive or quattro four-wheel drive system, and fully independent front suspension using MacPherson struts.
context_section_description: Mechanically, the TT shares an identical powertrain layout with its related Volkswagen Group-mates. The TT uses a transversely mounted internal combustion engine, with either front-wheel drive with 'quattro four-wheel drive' available as an option. It was first available with a 1.8-litre inline four-cylinder 20-valve turbocharged engine in two states of DIN-rated power outputs; 180 PS (132 kW; 178 hp) and 225 PS (165 kW; 222 hp). The engines share the same fundamental design, but the 225 PS version features a larger K04 turbocharger (180 PS version came with a smaller K03), an additional intercooler on the left side (complementing the existing right-side intercooler), larger 20mm wrist-pins, a dual tailpipe exhaust, intake manifold with inlet on driver's side, and a few other internals – designed to accommodate the increase in turbo boost, from roughly 10 pounds per square inch (0.7 bar) peak, to 15 pounds per square inch (1.0 bar). Haldex Traction enabled four-wheel drive, 'branded' as "Quattro" was optional on the 180 engine, and standard on the more powerful 225 version.
  The original four-cylinder engine range was complemented with a 3,189 cc (3.2 L; 194.6 cu in) VR6 engine rated at 250 PS (247 bhp; 184 kW) and 320 N⋅m (236 lb⋅ft) of torque in early 2003, which came as standard with the quattro four-wheel-drive system. In July 2003, a new six-speed dual clutch transmission – dubbed the Direct-Shift Gearbox (DSG), which improves acceleration through much-reduced shift times, was offered, along with a stiffer suspension.
