Streamlined race car: The award-winning Silver Arrows

16 cylinder, 520 hp, 400 km/h – that is what car fans today dream of and what enabled streamlined race cars to set records in speed in the 1930s. And curved panels made of PLEXIGLAS® played a significant part in this.

In the 1930s, five decades after the invention of the automobile, engineers started contemplating how they could achieve even higher speeds. Many of the cars built at that time were too heavy; their air resistance was very high and they consumed a great deal of fuel. Many manufacturers therefore turned to streamlining in order to design and build particularly streamlined, and thus fast, race cars.
