The 2026 Jensen Interceptor GTX is currently a track-only machine, but the reborn British brand is using it to develop future road cars. Its headline feature is a supercharged 6.8-liter V8 producing around 973 horsepower, with Jensen saying the engine could make up to 1,200 hp with a different tune.

The car’s latest public appearance also offered a chance to hear the engine at full throttle. The soundtrack comes from a heavily modified General Motors-based powerplant, routed through a manual gearbox.

Powertrain and performance

Jensen sources the engine from General Motors before sending it to Late Model Engine in Texas for an extensive overhaul. The company appears to retain the block while replacing or upgrading much of the surrounding hardware.

The engine receives CNC-machined cylinder heads, titanium valves and an upgraded rotating assembly. A Motec engine-management system controls the powertrain. In its current configuration, the supercharged V8 develops approximately 973 hp; Jensen says an output of up to 1,200 hp is possible with tuning.

That power reaches the wheels through a manual transmission, giving the GTX a distinctly old-school approach despite its modern engineering. The source material does not provide acceleration, top-speed or other chassis performance figures.

From race car to road car

Jensen says continued development of the Interceptor GTX could support production of a road-going version. The company has outlined two possible derivatives: a grand touring GT and a sporting GTR.

Both proposed models would draw from the track car’s engineering but would be adapted for public-road use. That means the GTX is more than a standalone racing special in Jensen’s plans; it is also a development platform for the brand’s return to road-car production.

Price and availability

There is no announced arrival date for either road-going Jensen, and the company has not disclosed pricing. For now, the Interceptor GTX remains the only confirmed model in this program and is intended for track use.

The project gives Jensen a clear technical identity as it works toward a modern interpretation of the Interceptor. A supercharged V8, a manual gearbox and nearly 1,000 hp form the core of the prototype, while the eventual GT and GTR models will determine whether that race-bred formula reaches customers.
