The 100 marked the return of the Audi brand producing cars of a more upscale nature. Powered by a 92-horsepower four cylinder engine driving the front wheels, a 4-speed manual was standard and a 3-speed automatic was optional. Front disc brakes were standard. When Volkswagen brought Audi to the United States for 1970, this model was known as the 100LS. (Photo credit: Sean Connor)
