The engine was lowered for a better center of gravity, and the frame was lightened with a number of holes drilled in the chassis.
The signature piano wire wheels used splines between the brake drum and rim, and relied on the radial spokes to handle cornering loads. 250 hp (186 kW) was on tap, and 8 were made.
The Type 59 did not debut until late in the 1933 season at the Spanish Grand Prix in San Sebastian, where the two cars raced finished a solid fourth and sixth.
The upgraded Type 59's only managed to score a lucky victory in the 1934 Belgian Grand Prix at Spa, when all top runners crashed out, making a one-two win with the second car.
Late in the year a Type 59 finished first in the minor Algiers Grand Prix.
