Niche British sports car marque Noble has finally unveiled the production version of its M600 Speedster.

We first saw the open-top supercar as a computer-generated rendering four years ago but at this week’s 2016 Goodwood Festival of Speed we were finally treated with the real deal.

The car needs to pass to crash testing before it can go on sale but Noble is confident it will be available by the end of the year, though only a European launch has been mentioned at this point.

The M600 Speedster features a removable targa-style roof. There’s nowhere to store the roof on the car so should the weather turn sour when out for a drive a canvas lining can cover the cabin temporarily.

Like the M600 coupe, drive comes from a twin-turbocharged version of the 4.4-liter V-8 built by Yamaha and previously fitted to Volvo’s first-generation XC90. Peak output registers at 650 horsepower and 604 pound-feet of torque, which is enough to hustle the car from 0-60 mph in 3.0 seconds and onto a top speed somewhere above 200 mph.

Drive is to the rear wheels only via a 6-speed, paddle-shifted sequential gearbox. Potential buyers can opt for a conventional manual if they #GiveAShift.

The expected starting price for the M600 Speedster is £220,000 (approximately $305,300).
