The first car from the entire Vision family from Hans-Albert Sender was presented to the public in 1983 at the Frankfurt Motor Show. The model was named Vision 1S. The car was based on Audi Quattro units, had a five-cylinder in-line engine with a volume of 2144 cc, which produced 230 horsepower and ... all-wheel drive. From zero to the first hundred, the car accelerated in 5.5 seconds. The body, as you might guess, was made of polymer materials.
