Ettore Bugatti had been the father of the 8-cylinder in line. The Type 35 was the most successful Bugatti. The arch-shaped radiator, evolved from the Type 13 Brescia, was the most recognisable feature. The Type 35 won over 1,000 races including the World Championship in 1926 after winning 351 races and setting 47 records in the two prior years. Type 35s averaged 14 race wins per week and won the Targa Florio for five consecutive years (1925 to 1929). The 35B of 1927 shared the 2.3 L engine of the 35T but had a large supercharger. Output was 138 hp. 45 were made. A British Racing Green Type 35B driven by William Grover-Williams won the 1929 French Grand Prix at Le Mans. The original model, introduced at the Grand Prix of Lyon on August 3, 1924, used an evolution of the 3-valve 2.0 L overhead cam straight-8 engine first seen on the Type 29. Bore was 60 mm and stroke was 88 mm. The new power plant had five bearings with an unusual ball bearing system allowing the engine to rev to 6000 rpm, and 90 hp was produced. Solid axles with leaf springs were used front and rear, with drum brakes at back, operated by cables. Alloy wheels were a novelty, as was the hollow front axle for reduced unsprung weight. The springs passed through the front axle rather than being U-bolted together as with earlier cars.
