Background
Hand-built between 1966 and 1976 at Jensen’s Kelvin Way Factory, the Interceptor marked a return to steel body shells (after the glassfibre CV8) and to cleaner Touring-designed Italian lines. The early bodies were built by Vignale in Italy, but Jensen soon brought production back to the UK.
As with the earlier CV8, Jensen chose Chrysler V8 power for the new GT, coupled with the same company’s ‘TorqueFlite’ automatic transmissions (driving the rear wheels through a limited slip differential) to complete the power train. Initially, the 6276cc motor was used.
The MkIII as seen here was introduced in 1971. Bumpers and headlights were revised, as were the seats inside. This last incarnation of the big grand tourer was divided up into three series; G-, H-, and J-series depending on the production year. The 6.3-litre was superseded by the (still Chrysler) 7.2-litre in 1971 as a reaction to smog rules introduced in the US. These emissions requirements had reduced the power of the mighty engine requiring an increase in capacity to rediscover some of those lost horses. The end result is very similar performance from the two engines – and many Jensen aficionados much prefer the earlier 6.3 as a sweeter, better-performing lump of Americana.
