Modern supercars push the boundaries of physics. While Bugatti and Koenigsegg battle fiercely to break the 500 km/h barrier, a certain Mercedes-Benz W125 Rekordwagen had already reached 432.7 km/h… back in 1938! With a drag coefficient of just 0.170, a supercharged 5.576L V12 producing 765 horsepower, and a weight of around 1,000 kg, the Rekordwagen was the pinnacle of efficiency. It held its record for an astonishing 79 years before finally being dethroned by the Agera RS and its monstrous 1,360 horsepower. Simply breathtaking.
