Gordon Murray Automotive has announced a racing-focused version of the T.50 supercar that will be even lighter, faster and more powerful. With all of the road-going T.50 supercars selling out within 48hr of the global premiere, customer demand has turned to the 25 racing models.

Priced at £3.1 million (before taxes), the racing variant (codenamed T.50s) weighs just 890kg, while its Cosworth GMA V12 engine develops even more power.

The new car also features a delta wing mounted to the rear of the car, which works with the rear-mounted fan, a new front splitter, underbody aerofoil and adjustable diffusers to generate more than 1,500kg of downforce — 170% of the weight of the car.

More than half of the exclusive production run has already been sold — before any details were released.

Mr Murray said: “With an unwavering focus on performance, and free from road-going legislation and maintenance considerations, the T.50s will achieve astonishing performance on track, demonstrating the full extent of the car’s capabilities.

“We’ve thrown everything at pushing this car beyond the levels of anything that’s been done before. It is a celebration of British engineering and our team’s extensive motor-sport experience.

“The extensively re-engineered T.50s features hundreds of significant revisions for race and track use over the road-going T.50.

“The stripped-back interior highlights the track focus and contributes to the new car’s 94kg weight loss. This enhanced lightweighting and the car’s phenomenal downforce ratio will ensure the car performs like nothing else on a racing circuit.

“Designing the racing car’s aerodynamics has been extremely rewarding. My love for motor-sport really fuelled the development of this car. The aerodynamics are so effective that the T.50s would be capable of driving upside down, and could do so at as little as 175mph.”

Stopping power is provided by the T.50’s Brembo carbon-ceramic discs with six-piston calipers at the front and four-piston calipers at the rear.

The brakes feature enhanced cooling via new ducting around each wheel — a necessary development to cope with the extremes of heat that could be generated by the 2.5-3g braking forces when racing.
