Schlörwagen from the front
The Schlörwagen was an experimental vehicle that caused quite a stir in 1939. Its aerodynamic performance, expressed as its drag coefficient (Cd value), was a mere 0.186 and therefore a real sensation. Subsequent measurements that Volkswagen conducted on a model during the 1970s confirmed the Schlörwagen's Cd of just 0.15. Modern cars possess Cd values of between 0.24 and 0.3 and therefore do not come close to the Schlörwagen's perfectly tailored aerodynamic shape. Only modern experimental vehicles such as the Volkswagen '1-litre car' or the ETH Zürich ‘PAC-Car II’ have lower Cd values.
