With power from a Cosworth V12, a manual transmission and a central driving position, the T.50 is shaping as something truly special.

Gordon Murray is readying a successor to the legendary McLaren F1, combining some old-fashioned Formula 1 technology with modern materials and a high-revving 3.9-litre V12.

The GMA T.50 is being billed as the 'purest, lightest, most driver-focused supercar ever' by Murray, who's renowned as one of the most innovative engineers ever to grace the Formula 1 paddock. Just 100 will be built, and they'll be priced from £2 million ($3.64 million) when they're delivered in 2022.

Initial figures are suitably impressive. Murray is chasing an overall weight of 980kg, and power will come from the 'highest-revving' V12 ever used in a production car. Redline is a staggering 12,100rpm, peak torque is 450Nm, and peak power will be 650hp (485kW).

Inspiration for the T.50 comes from one of Murray's best known F1 cars.

"I have absolutely no interest in chasing records for top speed or acceleration. Our focus is instead on delivering the purest, most rewarding driving experience of any supercar ever built – but, rest assured, it will be quick," Murray says of the car's inspiration.

That screaming engine will be mated with an H-pattern manual transmission, and the driver will sit in the middle of the cockpit, flanked by two passengers. Those touch points should all be familiar: the Murray-designed McLaren F1 was powered by a naturally-aspirated BMW V12 engine, had a manual transmission, and the driver sat in the middle of the cockpit.

Making sure the T.50 doesn't become a very expensive low-flying aircraft is a modernised take on the 'ground effects' fan Murray used on the BT46B Formula 1 car pictured above.

Rather than relying on wings, scoops and vents to create downforce, the underbody will do all the hard work, sucking the car to the road with a giant fan and clever, complex surface design. We can't wait for a closer look at how it works.

Dihedral doors will feature, and Murray says there will be a 'purity and beauty' about the design. It's hard to ascertain much about the car's look from the sketch provided, but it certainly has a clean profile if you ignore all the scribbling...

It'll be smaller than a Porsche 911 at 4380mm long and 1850mm wide, but Murray is promising it'll be "a sort of super GT car – absolutely road-focused with no plan to go racing, which is why the car set new standards for packaging and luggage space".

"The T.50 design has the same focus and betters the [McLaren] F1 in every area – ingress and egress; luggage capacity; serviceability; maintenance and suspension set-up. Also, driver-selectable engine maps ensure a driving mode to suit every situation."
