Light alloy cylinder head. 5 bearing crankshaft and camshaft. Chain driven overhead camshaft. Air intake and exhaust gas passages arranged in cross flow. Power from the clutch or torque converter is transmitted to the gearbox by chain drive (primary drive).

Power Transmission
Hydraulically operated single, dry plate clutch. A hydraulic torque converter replaces the clutch in cars with automatic transmission. Speed reduction between the engine and the driven wheels takes place in three stages: primary drive, gearbox and final drive. Top gear in the 4-speed and 5-speed boxes is direct drive (1:1). The universal joints are homokinetic and permanently lubricated.
