New Jensen Interceptor GTX Exhaust Sound Is Insane

The reborn Jensen brand is giving enthusiasts a taste of what could be coming, and the sound alone is enough to get attention. The 2026 Jensen Interceptor GTX is still undergoing development, but its supercharged 6.8-liter V8 is already showing just how serious this project has become.

The Interceptor GTX is currently designed as a track-only machine, serving as a development platform for future Jensen road cars. Under its long hood sits a heavily modified V8 producing around 973 horsepower. More importantly, Jensen has finally allowed the car to stretch its legs, giving us a chance to hear that supercharged engine working properly.

The engine begins life with General Motors hardware before being sent to Late Model Engines in Texas for extensive modifications. Very little is left untouched. The cylinder heads receive computer numerical control machining, titanium valves are installed, and the rotating assembly is upgraded to handle the enormous output.

Engine management comes from MoTeC, helping control a powertrain that is already producing approximately 973 horsepower. Even that apparently does not represent its full potential. Jensen says the engine could be capable of producing as much as 1,200 horsepower with different tuning.

Perhaps one of the most interesting parts of the package is how that power reaches the wheels. Instead of relying on an automatic or dual-clutch transmission, Jensen has paired the massive V8 with a manual gearbox. Nearly 1,000 horsepower combined with a supercharged V8 and manual transmission gives the GTX a distinctly mechanical character.

The track car is important for more than outright performance. Jensen plans to use what it learns from developing the GTX to create production models that can actually be driven on public roads.

The company has discussed 2 potential versions. A GT would focus more heavily on the grand touring side of the Interceptor formula, while a GTR would offer a more performance-focused interpretation. Both are expected to draw heavily from the engineering lessons learned with the GTX prototype.

There is still no confirmed production date for either road-going model, meaning plenty could change as development continues. What Jensen has already demonstrated, however, is its intention to preserve some of the qualities that made powerful British grand tourers so memorable.

For now, the Interceptor GTX remains a development car, but hearing its 6.8-liter supercharged V8 at speed makes the prospect of a street version considerably more interesting. If Jensen can bring this combination of huge power, manual shifting, and classic grand touring character to the road, the modern Interceptor could become one of the more unusual performance cars to emerge from Britain’s revived automotive brands.
