Specifications of the MD 90130 model

In order to enhance the car's handling, its center of gravity needed to be lowered and thus the driver's seat was shifted to the right, next to the transmission located above the engine's central axis.

This peculiar "offset" layout - called "monoplace decalée" in French, thus giving it the initials "MD" - was only made possible by shifting the entire engine/transmission entity 50mm to the left of the frame.

For the offset single-seaters, the chassis frame measures 850 mm, 530 mm in the anterior section and 600 mm at the rear.

Preselective gearbox comprising four speeds and a reverse. A "Wilson box" replaces the clutch.

An independent suspension system was designed for the front, while the rear retained the rigid axle. One main concern was to improve the car's aerodynamics and to this effect the front shock absorbers were removed and the upper protruding parts smoothed.

 Brakes

Drum brakes on all wheels for both the offset and the central single-seaters.

Both the offset and the central single-seaters are aluminum-bodied with 10/12mm sheets.

Made of 6 cylinders of 4482cc. It has a 93mm bore for a 110mm stroke.
