The LIX Wyvern (and LIP 6-cylinder Velox) were introduced in 1948. The Wyvern inherited the 1442cc 4-cylinder engine from the Prewar 12. David Jones restyled the Twelve body for the L-series at minimal cost, giving a new front and rear to make it resemble the Chevrolet Fleetline. The same body was also used for the L-type Velox which had to squeeze a 6-cylinder engine into the same bonnet. Replacing the L-series, the E-series gained a new body with American influenced styling that drew inspiration from the 1949 Chevrolet. After several new grilles and changes of windows, the Velox E-series was replaced by the be-winged Velox PA launched at Earls Court in 1957, and was given an uprated version of the E-series 2262cc 6-cylinder engine. After 173,000 were sold, the PA series was replaced by the Vauxhall PB series at Earls Court 1962. The PB versions of the Cresta and Velox used a brand new body far more European than the winged PA Cresta. In 1965 the Cresta PB was replaced by the 3.3-litre Cresta PC, but the Velox name was dropped at this point.
