The Type 59 was built with a 2.9 litre engine for the 750 kg formula.
It was the last classic Bugatti car, taking the design theme to its peak.
The car wasn't even built as a monoposto.
The car had brake drums integrated with the wheels, both being changed
at the same time. The engine was started by handle on the left side.
It proved to be a well balanced car with good road holding. Its major handicap
was the cable-operated brakes.
The first cars were ready for the 1933 Spanish Grand Prix. In 1934 the engine was enlarged
to 3.2 litre, the improved variant first seen at the French GP.
Compared to the German cars the T59s was totally uncompetive, expensive to maintain and had a low reliability.
No privateer was interested to order the car.
After the 1934 season Bugatti managed to sell four of the cars to the British privateers Earl Howe, Brian Lewis,
Charlie Martin & Lindsey Eccles.
In 1935 one car appeared at the French GP with a 4.9 litre T50 engine.
One of the chassis was used to built a single seater. It was first seen during practice for the Monaco GP.
In 1936 Bugatti was also able to enter and win with their T59 GP cars in the Comminges Sports car race, a maneuver
that created a storm of protests from the other teams.
Bugatti decided that two works T59 was enough and sent the third car to the 1936 Vanderbilt cup in New York to be raced by
Louis Meyer. The car was a non-starter but was sold after the race.

Bugatti decided to built a 4.7 litre light metal variant of their T50 engine, used in the Bugatti T54, for their T59 GP cars.
The engine, named T50B was first seen i the new "monoplace" in practice for the the 1936 Monaco GP. Raced by Wimille
that car finished second in the 1936 Vanderbilt cup.
For the 3 litre formula Bugatti constructed two reduced versions of the engine, a 4.5 litre unsupercharged
and a 3.0 litre supercharged. The 4.5 litre car was used in the 1937 "Million race" at Montlhéry, while the supercharged car
was seen in 1938 at the Cork GP and the French GP.
In 1939 the Bugatti team did not enter any GPs. A 4.7 litre car with a new streamlined body appeared only at the Prescott and
La Turbie hillclimbes and at the Coupe de Paris where it won. After the war the car won the
1945 GP de la Libération.
