The Bugatti Type 32 , also known as the Bugatti 32 Tank and Tank de Tours , is a competition car built for the French Grand Prix of 1923 , held on July 2nd at Tours . The nickname of the car derives from the particular shape of the car, which reminded that of a tank ,and the location of the Grand Prix. Another Bugatti racing earned himself the nickname of Tank for its aerodynamic, was the 57G Tank of 1936 The Type 32 also broke new ground by using a three-speed and reverse transaxle unit, the exceptionally short wheelbase and long straight-8 engine making a conventional gearbox difficult to accommodate. It also heralded an hydraulic front brake actuation.
Compared to the previous competition model, the Type 29 , dubbed Le Cigar , the cigar, due to its tapered shape Type 32 adopted:
- Longitudinal motor 8 cylinders in line and 5 five main bearings for the crankshaft ;
- 3 valves per cylinder, two intake and one exhaust , driven by a single cam shaft ;
- Gearbox with 3 ratios plus reverse gear, mounted in transaxle configuration on the rear axle (the 8-cylinder in-line engine and the short wheelbase did not allow the adoption of a traditional configuration);
- Hydraulically-actuated brakes at the front end and mechanically operated (metal cable) at the rear axle;
- Frame type underslung , with the platform below the axes, to lower the center of gravity ;
Despite the low center of gravity the road holding was not good due to the particular shape:
- The aerodynamics analogous to that of a wing profile meant that at speed the vehicle could tend to take lift ;
- The short wheelbase ;
The following Type 32 took part in the Grand Prix of Tours:
- N ° 6, driver Ernest Friderich , who finished 3rd at the finish line;
- N ° 18, Prince de Cystria pilot , retired at the 12th lap;
- N ° 11, pilot Pierre de Vizcaya , retired at the start following an accident;
- N ° 16, pilot Pierre Marco , retired on lap 3;
During the race the Type 32 reached straight, the top speed of 180 km / h.
