19. 1928 Mercedes Benz SSK
The SSK stands for “Super Sport Kurz” which translates to SuperSport Short. It was a shorter wheelbase version of the Mercedes-Benz Modell S, and is famously known as the last car designed by the legendary Ferdinand Porsche before he left to form his old company. It featured a 6-liter engine that could produce 200-300 metric horsepower and a top speed around 120 miles per hour, easily the fastest car of the time. Fewer than 40 were ever produced.
