Gordon Murray is to work with the Racing Point Formula 1 team on the aerodynamic development of his T.50 supercar, using the team's windtunnel.
The former Brabham and McLaren designer and his colleagues at Gordon Murray Design are to use Racing Point's facility in Brackley, and "will gain insight and expertise" from the team's engineers.
The first official image of the T.50 shows a fan that is at the heart of the car's advanced aerodynamics, echoing the Brabham BT46B that Murray designed in 1978, and which won the Swedish GP on its only race appearance.
A 40% scale model will be used in the Brackley tunnel to design the car, which Murray has already confirmed could compete in the new Hypercar class of the World Endurance Championship.
GMA says that the car "features six different aero modes that optimise the car for different scenarios to balance traction and outright performance", claiming its most extreme engine mode will produce 700bhp.
The car features a bespoke Cosworth V12 that revs to 12,100rpm, and weighs just 950kgs.
Like Murray's McLaren F1, it features three seats and a central driving position.
"F1 remains a deep passion of mine, so partnering with Racing Point to develop the T.50 is hugely exciting," said Murray.
"I've dreamt of delivering a road car with a ground-effect fan since I designed the Brabham BT46B F1 racing car in 1978.
"The system on the T.50 is much more sophisticated than the Brabham's and will benefit enormously from Racing Point's expertise and resources.
"We were highly focused on achieving the purest possible form for the T.50, an objective we've achieved through world-first engineering innovations and active underbody aerodynamics.
"We will reveal the completed design at the T.50 supercar's global debut in May."
Lawrence Stroll, who led a consortium to successfully take over the struggling squad last year, said it was a "personal pleasure" to work with Murray on the new car.
"Working on the T.50 with Gordon Murray Automotive is an honour and a privilege for everyone at Racing Point," said Stroll.
"Our aerodynamicists will utilise our wind tunnel to harness the very latest F1 expertise and experience for the T.50 project, ensuring Gordon's revolutionary fan concept delivers its full potential.
"I have admired the design and engineering skills of Gordon Murray since his earliest days in F1, so it is a personal pleasure to support this project, which truly rewrites the rulebook on aerodynamics."
A production run of just 100 cars, priced at more than £2m before tax, are being built - and most already have customers, with deliveries starting in January 2022.
