The Type 35 was the most successful of the Bugatti racing models. Its version of the Bugatti arch-shaped radiator that had evolved from the more architectural one of the Bugatti Type 13 Brescia, was to become the one that the marque is most known for though even in the ranks of the various Type 35s there were variations on the theme.
The original model, introduced at the Grand Prix of Lyon on August 3, 1924, used an evolution of the three-valve 2.0 L (1991 cc/121 in³) overhead cam straight-eight engine first seen on the Type 29. Bore was 60 mm and stroke was 88 mm as on many previous Bugatti models. Ninety-six examples were produced. This new powerplant featured five main bearings with an unusual ball bearing system. This allowed the engine to rev to 6,000 rpm, and 90 hp (67 kW) was reliably produced. Solid axles with leaf springs were used front and rear, and drum brakes at the back, operated by cables, were specified. Alloy wheels were a novelty, as was the hollow front axle for reduced unsprung weight. A second feature of the Type 35 that was to become a Bugatti trademark was passing the springs through the front axle rather than simply U-bolting them together as was done on their earlier cars. A rare version was de-bored (to 52 mm) for a total displacement of 1.5 L (1494 cc/91 in³). There are two of these cars in New Zealand.
Ettore Arco Isidoro Bugatti (15 September 1881 – 21 August 1947) was an Italian-born French automobile designer and manufacturer. He was born into an artistic family with its origin in Milan, Italy. Ettore's father intended that he follow a conventional technical apprenticeship with one of the Milanese tri-/quadricycle manufacturers, but the boy quickly demonstrated a deep instinctive understanding of wide range of aspects of motor-vehicle construction, and with Prinetti & Stucchi constructed his "Bugatti Type 1" in 1898.
