A McLaren Speedtail development car has reached 250 mph more than 30 times during high-speed testing at the Kennedy Space Center in Florida, USA.
Famously exuberant chief test driver Kenny Brack consistently reached the impressive maximum speed figure in Speedtail prototype ‘XP2’.
The tests are part of a high-speed validation regime that has already carried out flat-out runs at Idiada in Spain and Papenburg in Germany.
McLaren is making just 106 Speedtails, each boasting 1,070 horsepower – that’s enough to accelerate from 0-196mph in less than 13 seconds.
A 1.1-litre version of the Ford Fiesta, Britain’s best-selling car, takes 13.8 seconds to reach 62mph.
Each costs £2.1 million ($2.7 million).
“It’s fitting that the Speedtail’s high-speed test programme concluded with multiple maximum-speed runs at a location strongly associated with pushing the boundaries of extreme performance and engineering excellence,” said McLaren Automotive CEO, Mike Flewitt.
“The Speedtail is a truly extraordinary car that epitomises McLaren’s pioneering spirit and perfectly illustrates our determination to continue to set new benchmarks for supercar and hypercar performance.”
The F1 factor is also why McLaren is only making 106 Speedtails: to match the number of F1s made.
The Speedtail is a substantial 5.2 metres long (the same as a long-wheelbase Range Rover) and is described as the most aerodynamically efficient McLaren ever.
The Speedtail is also a hybrid: it has a petrol-electric drivetrain that self-charges when the vehicle is driven – although McLaren will also give owners a wireless trickle-charge pad to keep the hybrid system in peak condition.
McLaren says production of the first Speedtail hypercars is already underway at its Woking production centre. Deliveries will begin in February 2020.
