Engine

The engine was derived from the existing unit, but the cylinder bore was increased by one millimeter which gave rise to an overall increase in engine size to 2289cc. Despite the slightly larger engine size and the inclusion of two twin-chamber Solex 30 JFFK carburetors, claimed power was unchanged at 55 PS (40 kW): the compression ratio was set at the relatively low value of 1 : 6.6. Claimed top speed was 116 km/h (72 mph).[5]
