A true homologation special, this TVR T440R is the only one of its kind ever produced. Made to homologate an endurance race car in 2003, the car was only recently recommissioned and is up for sale.

The story of the TVR T440R starts with the T400R (aka the Typhon) race cars that were built to compete in endurance racing at Spa, Sebring, in British GT, and, of course, Le Mans. In order to obtain FIA homologation, TVR had to build four road cars.

The British company chose to build three Typhons and this, the T440R. The Typhons were initially supposed to feature a supercharged 4.0-liter straight-six but were instead finished with a naturally aspirated 4.0-liter engine.

The T440R, meanwhile, was fitted with a naturally aspirated, 4.2-liter straight-six that incorporated a gas-flowed cylinder head, a steel crankshaft and conrods, as well as a carbon fiber airbox with six upper injectors and bespoke exhaust headers. For road use, the engine makes 440 hp (446 PS/328 kW), down from the supercharged race car’s 585 hp (593 PS/436 kW).

The underfloor is flat for better aerodynamics and is made of resin-sandwiched aluminum honeycomb. A separate carbon-fiber tub is bonded to the chassis and the carbon fiber bodywork is bonded to the tub and the floor.

Thanks to its power and lightweight construction, the car will hit 62 mph (100 km/h) in just four seconds and can go all the way up to 200 mph (320 km/h). Quite impressive numbers for 2003, and still more than respectable today.

Inside, the T440R has four seats and plenty of exposed carbon fiber, as well as Willans racing harnesses. The seats are trimmed in red and black leather and the Alcantara headliner is a surprisingly modern touch.
