SS Jaguar and Jaguar 1½ Litre

The smallest model of the range originally featured a 1608 cc side valve Standard engine but from 1938 this was replaced by a 1776 cc overhead-valve unit still from Standard who also supplied the four-speed manual transmission.

Pre-war the car was available as a saloon or drophead coupé but post war only the closed model was made. Up to 1938 body construction on all the models was by the traditional steel on wood method but in that year it changed to all steel. Performance was not a strong point but 70 mph (113 km/h) was possible: the car featured the same cabin dimensions and well-appointed interior as its longer-engined brothers.

Despite its lack of out-and-out performance, a report of the time, comparing the 4-cylinder 1½-litre with its 6-cylinder siblings, opined that the smallest-engined version of the car was “as is often the case… the sweetest running car” with a “big car cruising gait in the sixties”.

Mechanically operated brakes using a Girling system were fitted.
