The car was fitted with a 1,442 cc (88.0 cu in) four-cylinder engine, generating 35 bhp (26 kW), with a top speed of 62 mph (100 km/h).

In August 1951[7] a completely new Wyvern was launched, featuring a modern Ponton, three-box shape in a unitary construction body.

In spite of the abandonment of the old RAC horsepower tax system which favoured long stroke engines, the old long stroke four cylinder 35 bhp (26 kW) engine from the L-series was retained and permitted a claimed top speed above 62 mph (100 km/h) despite the car's increased size.

[5] After only six months production of the rebodied Wyvern the car received, in April 1952, Vauxhall's new short stroke 1508 cc four-cylinder engine.

Although the external appearance was very like that of the British cars, which featured unitary construction, some of Australian Vauxhalls retained a separate chassis frame.

[10][11] The new post-war Holden car was "chassisless", so the Vauxhall gave GMH customers the option of a ute or a convertible with a chassis.

The six-light body with protruding luggage boot built to Holden's "turret-top" design used many of the front pressings of the unitary construction British Vauxhall H Series.

[14] The saloon featured a six light body [15] with a side window behind each rear door unlike the British H Series 10-4 model.

Besides having a separate chassis the Australian sedan differed from its English counterpart in having a longer passenger cabin, a more rounded boot and an additional side window behind the rear doors.

[27] 1954 was the last year for the Coupe Utility,[26] and the Vagabond was not included in the facelifted E Series range released in April 1955.
