Jensen had extensively used glass-reinforced plastic for the fabrication of body panels in the preceding two decades, but the new Interceptor was a return to a steel body-shell.

The Interceptor may have taken some styling cues from the Brasinca Uirapuru,[2] with a distinctive large, curving wrap-around rear window that doubled as a tailgate.

Jensen had fallen on hard times by 1975, owing to the then world-wide recession, and to problems with its Jensen-Healey sports car.

Later, a group of investors trading under the new Jensen Cars Limited brandname stepped in and relaunched production of the 1970s Interceptor, which was briefly re-introduced in the late 1980s as the Series 4 (S4) which was an updated version of the original Interceptor V8 series giving a new lifespan for the Jensen brand and its car production was resumed.

The car came back as a low-volume hand-built and bespoke affair, marketed in a similar way to Bristol, with a price of £70,000.

Though the body remained essentially the same as the last of the main production run of Series 3, the engine was a much smaller, Chrysler-supplied, 360 cubic inch (5.9-litre) which used more modern controls to reduce emissions comparatively and still producing about 250 bhp.

At the time it was hailed as a remarkable development, coming also with Dunlop Maxaret mechanical anti-lock brakes and traction control.

A convertible with powered soft top was introduced in 1974, mainly intended for the American market but also sold in Europe.

A Jensen specialist JIA based in Banbury Oxfordshire, England, rebuilds original Interceptors using modern components, with General Motors supplied LS 6.2-litre naturally aspirated or supercharged engines and six-speed automatic or manual transmissions.

In May 2010, Jensen International Automotive was set up, with the financial backing of Carphone Warehouse founder and chairman Charles Dunstone who joined its board of directors.
