Audi A3 3-door
The original A3 was introduced in the European market in 1996, marking Audi's return to the production of smaller cars following the demise of the Audi 50. This was the first Volkswagen Group model to use the "PQ34" or "A4" platform, bearing a natural close resemblance to its contemporary, the Volkswagen Golf Mk4. The car was initially available only with a three-door hatchback body, in order to present a more sporty image than the Golf, in both front- and four-wheel drive. All engines were an inline four-cylinder configuration, and were transversely mounted. After the A4, the Audi A3 was the second model in the Audi lineup to use five valves per cylinder.
In 1999, Audi expanded the range with the introduction of more powerful versions: a 1.8 Turbo rated 180 PS (132 kW; 178 hp), and a 1.9 TDI diesel engine with Unit Injector "Pumpe Düse" (PD) technology and variable geometry turbocharger. The four-wheel-drive A3 1.8T quattro used either the 150 PS (110 kW; 148 hp) or 180 PS (130 kW; 178 hp) engine, and the same Haldex Traction-based on-demand four-wheel drive system as the Audi S3 and the Audi TT. 1999 was also the year Audi was forced to bow to market demands and introduced a hastily-conceived five-door body that the company had not previously intended to produce.
In late 2000, the A3 range was revised with new headlights and rear light clusters, other minor cosmetic changes, an improved interior, and the introduction of a six-speed manual gearbox, on the 180 PS (132 kW; 178 hp) 1.8 Turbo and the brand new 130 PS (96 kW; 128 hp) 1.9 TDI.
