The final resurgence of the original Bugatti was the Type 251, completed in 1955. Designed by Gioacchino Colombo of Ferrari fame, it was powered by a new 2.5 L (2486 cc/151 in³) straight-8. Uniquely, this engine was mounted transversely, behind the driver. For the first time in a Bugatti, an oversquare engine was used with a 76 mm bore and 68.5 mm stroke. A de Dion tube rear suspension was also a novelty for the company, though it was in vogue at the time. The Type 251 was entered in the 1956 French Grand Prix, driven by Maurice Trintignant, but was not competitive and retired after 18 laps.
