In March 1945 SS Cars Ltd became Jaguar Cars Ltd, and they also bought out the tooling of the Standard six cylinder engines for their own production, although the 4-cylinder engines continued to be made by Standard. Production of the 1.5-litre, 2.5-litre and 3.5-litre cars restarted with few changes although most cars were now saloons, and no 1.5-litre dropheads were now made. The 1946 benefitted from a new Hypoid bevel rear axle which allowed a lower car and a sleeker appearance. At the 1948 London Motor Show Jaguar announced the Jaguar MkV, which was significantly different to the prewar model (now referred to as 'MkIV'). The Mk V was launched with an all new rigid chassis with independent front suspension, hydraulic brakes, and only fitted with the six cylinder engines.
