The Ventoux was an automotive engine designed by Renault for the Renault 4CV, used subsequently until 1997, and named after Mont Ventoux in Provence.
The engine was liquid-cooled, with four cylinders in line. It was also characterised by its three main bearing design and its piston stroke of 80 mm. It used a lateral camshaft to operate overhead valves.
The engine was produced from 1947 to 1984, in displacements of 603 cc, 748 cc, 782 cc, and 845 cc, the differences being effected by changing the cylinder bore diameter. Ford do Brasil extended the engine to 1300 cc and 1400 cc to use it on the Ford Corcel.
