The only external difference between the TVR Grantura and TVR Vixen S1 was a larger bonnet vent. In 1968 the TVR |Vixen S2 was introduced. Mechanically unchanged, the longer wheelbase (7ft 6in) chassis from the Tuscan V8 SE was used. The body was almost identical to the LWB Tuscan body, with longer doors, and Cortina Mk2 tail lamps replaced the round Mk1 lamps. The bonnet had a long bulge running from front to rear, which has subsequently become known as the ‘sausage’ bonnet.The restyling was done in phases, with some early cars having a prominent central bulge, and later cars having twin intake ducts at the front corners of the bonnet. The tail lamps were updated from the round Cortina Mark I style to the newer wraparound Mark II style. Also very significant was the fact that the body was bolted (rather than bonded) to the chassis, meaning that it could be easily removed for repairs.
The 1600cc Ford engine used in the Vixen S2 (as well as select other Vixen and TVR models) is the popular Ford cross-flow pushrod unit which comes from the Kent family of British Ford engines.Â This engine has its principal claim to fame as the motivation for the Mk1 Ford Escort Mexico and Mk2 Cortina 1600E
