Replacing the L-series, the E-series gained a new body with American influenced styling launched in 1951 for the 1952 model year. Under David Jones The E-series body drew inspiration from the 1949 Chevrolet. The EIP series was launched as the 1442cc Wyvern and the 2275cc Velox, but a new 4-cylinder 1507cc engine was given to the Wyvern in 1952 and a new 6-cylinder 2262cc unit to the Velox at the same time. For 1955 new grilles are given to the big Vauxhalls and rear spats for the Cresta and Velox. The EIP Cresta was new for late 1954, introduced as a kitted out upmarket version of the Velox set against Ford's Zephyr Zodiac. The biggest change came in 1956 when body revisions included new larger front and rear screens and thinner pillars and grilles again were altered. Model codes changed to EIX for Wyvern, EIP for Velox and EIPC for Cresta. For the final year, 1957, new horizontal grilles were given to all models and larger tail lights with red and amber lenses. This was the final year for the 'Wyvern' name as this car was replaced by the new FA body Victor in 1958, whilst the Velox and Cresta were succeeded by the PA models.
