Plenty of super-quick road and race cars have ripped their way up the Goodwood Festival of Speed hillclimb over the past 30 years, but none has gone faster than the McMurtry Speirling, which devoured Lord March’s driveway in 39.08 seconds. And now the Brit startup has announced a production version of the pocket-sized hypercar prototype and claims it’s even speedier.

The new car is called the Speirling Pure, costs a hefty £820,000 ($1.05 million) plus taxes and is limited to just 100 units, the first of which will be delivered to deposit holders across the globe in 2025 following a world debut at this July’s Festival of Speed. Like the original prototype, the Pure is a strictly track-only toy, and McMurtry says it is eligible for the GT1 Sports Club, granting it access to driving programs held during SRO GT World Challenge race weekends worldwide.

Though the pictures probably don’t show it, the Speirling Pure is absurdly small, measuring just 135.8 in (3.45 m) long, 62.2 in (1.58 m) wide, and only 40.2 in (1.02 m) from the ground, to which the car desperately tries to attach itself courtesy of its fan-operated, on-demand downforce technology.

McMurtry says the Pure’s revised fan system is both lighter and more efficient, and together with tires that are 28 percent wider at the front and 25 percent broader at the back helps the single-seat EV deliver in excess of 3G of cornering stick. That’s around half of what an F1 driver might experience, but it’s still going to really test the neck muscles of anyone who doesn’t already look like Channing Tatum. And contrary to what you might think, Tatum could probably fit inside because the Pure’s steering wheel and pedals adjust to accommodate drivers up to 6 ft 7 in (2.0 m) and 330 lbs (150 kg).

Putting someone that chunky in would be a shame though, because the car itself only weighs around 2,200 lbs (1,000 kg), though with a peak output of 999 hp (745 kW / 1,013 PS) it’s still going to feel uncomfortably rapid. McMurtry quotes a 190 mph (306 km/h) top speed and says the 60 kWh battery would last 10 laps of Silverstone’s National circuit at lap-record pace, which is probably more than most people will want to do in one stint with 3G forces trying to squeeze their brain out of the earhole. It can then be charged in under 20 mins while you recover.

If you were a millionaire trackday nut would you buy the Speirling over a more traditional track-only supercar?
