For many years, it was clear in the heads of the bosses at Audi that the way to move forward, and to sell more cars was to be technologically innovative. While it has not always worked when the technology wasn’t ready for prime time, it has otherwise served them quite well. Meet the 1983 Audi 100 CD, one of the best examples of the fruits of long years of research. The ‘CD’ stands for ‘drag coefficient’, which is the measure of how much a car is aerodynamic. The Audi 100 CD boasted a CD of 0.30, which is excellent even by today’s standards. The thousands of hours the engineers spent in the wind tunnel fine-tuning every aspect of the car also have their aesthetic benefits, such as flush-mounted windows, bulging doors and more.
The Audi 100 CD (1983 version) was powered by a 1.8-liter, inline four-cylinder engine, which developed 113 horsepower, and which strangely enough, was mounted longitudinally This engine configuration in a front-wheel drive was unique to Audi. While this number doesn’t seem very impressive), the Audi 100 CD could reach a top speed of 128 mph (over 200 km/h), which made it quite the comfortable highway cruiser. Even the 0-60 speed wasn’t bad, at 9.5 seconds, which goes to say that design and aerodynamics have a huge role to play, particularly at higher speeds when a large part of the car’s horsepower is used only to push the air ahead of the car.
Thanks to its small engine, it was also quite thrifty as far as fuel economy goes, and was further appreciated for that.
