This is the Devon Motor Works GTX supercar, which has been track testing ahead of its unveiling at this week's Pebble Peach Concours.
The GTX, which is due to go on sale next year, is being funded by businessman Scott Devon. These are the first official pictures of the car; previous images have been artist's renderings.
Although little information has been released about the car so far, its makers have announced that they will be chasing the Nurburgring production car lap record with it.
To this end, it has hired endurance racer Justin Bell, son of Le Mans legend Derek, to undertake the bulk of the development driving.
The Nurburgring's production lap record is currently held by Radical's SR8, which lapped in 6min 55sec.
Although unconfirmed, reports suggest the car will have over 650bhp and an ultra-light carbonfibre body. It also has a distinctive glass roof section, demonstrating the car hasn't been designed purely with track work in mind.
The interior is said to be close to production ready, and mixes a state-of-the-art electronic dashboard with a gearlever that harks back to the 1970s muscle car era.
The car has been designed by Daniel Paulin, the man responsible for the Fab 1 Thunderbird and the Focus C-MAX concepts for Ford.
