McLaren Automotive's 1.42 million-pound ($1.82 million) Elva roadster has an open cockpit to give its occupants what the company calls an "elemental" driving experience.
McLaren revealed the roadster, which has no roof, windscreen or side windows, on Wednesday.
The Elva is powered by McLaren's twin-turbocharged V-8 tuned to make 804 hp. The car can accelerate from 0 to 100 kph (62 mph) in under three seconds, McLaren said.
The car uses a carbon-fiber chassis and body to reduce weight. McLaren said it's the lightest road car it has made, without giving its weight.
The company will build 399 units of the Elva, which will cost 1.42 million pounds ($1.82 million) including local taxes in McLaren's UK home market.
The Elva is a direct rival to the Ferrrari's Monza SP1 and SP2 unveiled in September. Like the Elva, the two Ferraris have no roof nor windscreen and have a similar price tag.
The Elva is named for a defunct British sports car company that produced a series of sports cars in partnership with McLaren's founder Bruce McLaren in the 1960s. The name Elva was taken from the French for 'she goes' (elle va).
The Elva has an active air management system to shield the occupants from being buffeted by turbulence that a windscreen could normally direct away from the cabin.
The system channels air through the nose and out of the hood to keep it away from the cockpit and leave occupants in what McLaren said is a "relative bubble of calm."
A windscreen is an option.
