Velox EIP/EIPV & EBP (1951–57)
In August 1951[13] a longer, wider Velox was launched, designated as the EIP series,[11] and featuring a modern 'three box' shape and integral construction. The body was again shared with the 4-cylinder-engined Wyvern. The car was launched with the previous model's engine but with power output increased to 58 bhp.
A car with the original 2275 cc engine tested by The Motor magazine in 1951 had a top speed of 77.4 mph and could accelerate from 0-60 mph in 23.7 seconds. A fuel consumption of 23.5 mpgimp was recorded. The test car cost £802 including taxes.[14] In the same year, the magazine tested the similarly sized Ford Zephyr Six. Ford's test car was fitted with options including a radio, a heater and leather seating: thus equipped the Zephyr came with a recommended retail price of £842.[15]
In April 1952 the Velox was redesignated as the EIPV series,[11] and received a new over-square 2262 cc engine which had been in the development pipeline for several years.[9] This provided either 64 bhp or, with a compression ratio improved to 7.6:1, 68 bhp of power.
A further test in 1952 by The Motor magazine of the EIPV with the short-stroke 2262 cc engine, found the top speed had increased to 80.4 mph and acceleration from 0–60 mph to 21.4 seconds. A similar fuel consumption of 23.6 mpgimp was recorded. The test car cost had risen to £833 including taxes.[16]
In December 1952 General Motors Holden launched a tourer and coupe utility version of the EIPV Velox and EIX Wyvern models on the Australian market, these cars' chassis were prefixed EBP for the Velox and EBX for the Wyvern. Both these cars used modified Vauxhall bodies affixed to the Bedford CA chassis. The tourer was originally to be called the Caleche but by the time of launch the model name was changed to Vagabond. The Vagabond was a two-door five seater with folding top and side curtains. It did not survive the 1955 face lift. The coupe utility continued on (Velox only from 1955) until officially withdrawn at the end of the 1957 model year.
In August 1954 a significant facelift[11] was applied. Most obvious of the many cosmetic changes was a new front grille and trafficators were replaced by flashing lights (red at the rear, US-style). More important was the introduction at this time of a sister model, branded as the Vauxhall Cresta. In addition to superior equipment levels, the Cresta was distinguished by a two tone paint finish. The 1954 VELOX also differed from the 1953 which had a side opening bonnet, by having a front opening bonnet
Detroit was by now favouring annual facelifts, and Vauxhall reflected that trend, announcing further facelifts for 1956 (wind-up windows, larger rear window, wider grille slats, separate amber rear flashing indicator lights replacing US-style red units incorporated into the brake/tail light lens, new instrument graphics) and again for 1957 (electric wipers, larger tail lights, new grille, new 'magic ribbon' AC speedo) in line with the Wyvern model.[11] Technically, however, there were no further changes until the arrival of a completely new Velox in October 1957.
In Australia, Holden built a quantity of utilities (pickup trucks) as well as the 2-door Vagabond Convertible based on the EIP Velox. These had a separate chassis - prefixed EBP - with the Australian bodies fitted to them. The Velox was also assembled at the General Motors New Zealand plant in Petone, north of Wellington, through to and including the PC Cresta of the late 1960s, by which time buyer favour had turned to the similarly sized GM-dealer stablemate from Australia, the Holden Belmont/Kingswood.
