This is the original Victor, launched on 28 February 1957, with a production run of more than 390,000 units before it was withdrawn in 1961. The car was of unitary construction and featured a large glass area with heavily curved windscreen and rear window. Following American styling trends then current, the windscreen pillars sloped forwards. In fact, the body style was derived directly from the classic ′55 Chevrolet Bel Air.

Bench seats were fitted front and rear trimmed in Rayon and "Elastofab", and two-colour interior trim was standard. The Super model had extra chrome trim, notably around the windows; remnants of the signature Vauxhall bonnet flutes ran along the front flanks and the exhaust pipe exited through the rear bumper. The car was equipped with arm rests on the doors, door-operated courtesy lights, a two-spoke steering wheel, and twin sun visors. The Vanguards model is the pre-facelift version made from 1957 to 1959, the later cars have simplified rear wing treatment and less of an American look overall.
