Summary

The 1931 Type 53 is the only all-wheel-drive Bugatti ever built in the era of Ettore Bugatti. Although it achieved some victories, the concept ultimately proved unsustainable. The complex axle design made the steering so heavy that even experienced drivers apparently struggled with it.

Reinventing the racing car - this motif runs through the entire history of racing car technology up until the 1980s. Then, safety regulations and ever-improving simulation tools increasingly led to a technical convergence, to a kind of standardization, so that today Formula 1 cars differ externally almost only by aerodynamic refinements, some of which are barely perceptible. Before 1992, outstandingly innovative cars were created every decade, which were not always successful or did not even make it onto the road, but often provided impetus for new standards later on, until these were sometimes called into question again.
