Audi – Timeline 90s
With the 1988 model year, a new 2-door Coupé was introduced in Europe, basically a B3 saloon with a shortened wheelbase and a modified rear end. It came with the 115 PS 2.0E as well as the two 2.3E engines. It later served as a basis for the B4 Coupé and Cabriolet. These models dropped the “80” appendage and were simply known as Audi Coupé and Audi Cabriolet. Because of the heavy re-engineering involved in the cabriolet version, this model was essentially carried on until the year 2000, long after the other B3 models had been replaced by B4 versions.

The Audi RS2 was generally only available as an Avant, although four 4-door saloon models were officially produced by the factory, including one for the chief of the RS2 development programme. The RS2/Porsche link is further exemplified by the RS2’s dual circuit Porsche braking system (wearing Brembo calipers with a Porsche name), 7.0Jx17″ alloy wheels which were identical in design to the Porsche 911 Turbo wheels of that era, and side view mirrors are also borrowed from the Porsche 911 Turbo. Additionally, the word “PORSCHE” is inscribed in the RS2 factory emblems affixed to the trunk and front grille, and on the engine’s inlet manifold. Porsche modified the Avant S2 body optics, added more power, better brakes, bigger anti-roll bars to front and rear, fine tuned the interior and a super-sports estate was born. Porsche’s involvement in the project was on the strict understanding that a coupé model would not be produced, as this was felt to be too close to Porsche’s own products.

The Audi Quattro Spyder and the Audi S2 Coupe look really good even for now.
