Gordon Murray Automotive has gone into more detail on the upcoming T.50 supercar, including its fascinating fan system.

The 400mm fan is mounted at the rear and sucks air through the wheel arch and from over the rear diffuser. According to GMA it helps with cooling, downforce, efficiency and drag reduction. There are also two active wings at the rear of the car that can move to either add downforce or reduce drag.

Murray spoke to Road & Track about his unique system, saying: "What we do when the fan fires up, and we want more downforce at lower speeds, is we open the slots and spool the fan up to maximum, and we remove all the dirty air and the boundary layer, and that means that the air has to follow the surface. It's forced to follow the surface to fill the vacuum that was left there," Murray told Road & Track.

The aero system has multiple modes, including Vmax. This adjusts all the active aero (fan included) into a low-drag setting and boosts engine output to 522kW thanks to a 48-volt mild-hybrid system. For those high-speed corners, there’s also a maximum downforce configuration.

The T.50 uses a Cosworth-built 4.0-litre naturally aspirated V12, producing 485kW/450Nm. The donk can spin out to 12,100rpm, on par with some superbikes and sends its power through a six-speed manual to the rear wheels. Weight is kept to an ultra-trim 980kg thanks to an abundance of carbon fibre.

The T.50 will debut in May 2020 and only 100 will be built. Expect to pay GMA £2 million to get a foot in the door.
