Audi 90 Quattro
The Audi 90 was an upmarket version of the Audi 80. The original Audi Cabriolet was badged thus, without a number, but was closely related to the 80/90.
In 1987, the inline five-cylinder Audi 90 was reintroduced as an upmarket, more luxurious variant of the 80. The 90 differs visually by the full width tail-light panel; headlights which featured additional high-beam lights and a slightly different front grille. The most obvious visual difference between the 80 and 90 are the indicators, which are moved from beside the headlights to the bumpers next to the fog lights, which were standard fitment on the 90. From 1989 to 1991 the 90 also offered the first 20-valve engine from Audi since the turbocharged engine used in the Audi Sport Quattro. This engine produced 170 PS (130 kW; 170 bhp) and featured in the front wheel drive 20V, 20V Sport and four-wheel drive 20V quattro derivatives. The non-quattro 20V models were 120 kg lighter.
