Tank!

The 1923 Bugatti Type 32, nicknamed the “Tank”, featured a number of mechanical innovations in addition to its radical, aerodynamic shape, and rode on a very short 79.5” wheelbase. Due to Bugatti’s inexperience with aerodynamics the car had a tendency to lift off the ground at speed.

Four of these racers were built, to compete in the 1923 French GP, each powered by a 2.0 litre straight-8 engine. The best they could manage was a 3rd place finish with car number 6, and Bugatti quickly abandoned further development, to concentrate on other models. The Type 32 car has been produced before by other companies in 1:43rd, but I can’t say the last time I saw any.
