Here is a little history about Audi 90

Audi 90 is a medium-sized car produced by the German concern Audi from 1987 to 1991.

Audi 90 has completed the line of family sedans with improved aerodynamics. The main rivals of the Audi 90 were the Mercedes 200 series and the BMW 5 series. In general, the car Audi 90 is based on the second generation 80, which came out a year earlier and was a great success. From its four-cylinder predecessor 90 received a body. The stiffer suspension was standard on only four-wheel drive versions. In addition, the same versions received an anti-lock braking system. The aerodynamic drag of the Audi 90 models decreased from 0.39 to 0.31, which made them very fast. Sedan 90 received a front spoiler, painted in body color. All-wheel drive versions also had a rear spoiler, along with alloy wheels and disc brakes.

In Europe, the Audi 80 was the standard model, and after 1984, the appearance of the Audi 90 was as a large-scale version of the 80 – that is, with more options: in addition to turbodiesel, which was available for the 80, there were two 5-cylinder gasoline engines of 2 liters and 115 hp (160 hp), as well as 2.2 liters and 120 hp (136 hp), which was later modified to 2.3-liter.
