Want to drive upside down? The £1.2m production-ready McMurtry Spéirling is here

In 2022, a prototype version broke the Goodwood Festival of Speed’s hillclimb record. In 2025, it went so fast around the Top Gear test track, it dislodged an old Renault F1 car.

And later that year, it literally drove upside down. Now you can enjoy such hijinks – if you have access to around £1.2m and the reactions of an F1 driver. Welcome to the final production version of the groundbreaking McMurtry Spéirling.

You’ve seen this car countless times, so keen McMurtry enthusiasts will likely spot the changes. For those who don’t speak in downforce, here’s what’s going on: the battery’s now bigger, measuring in at 100kWh, up from the 60kWh used in the prototypes. As a result, the whole car’s grown a bit too.

There’s a “standardised, modular McMurtry battery design with futureproofing built in for evolution upgrades” (upgrades!), up to 200kW of brake-energy recovery, new motors with more torque, and a better cooling system.

Motorsport bits that have escaped the pit of real-world motor car regs include a swan-neck rear wing and a new carbon fibre monocoque that handily adds a bit more elbow and leg room, and makes it easier to get in and out of the thing. Assuming the g-forces haven’t already crushed your internals and you're able to move freely.

Plus, McMurtry has introduced novel additions like: headlights! Hazards! Brake lights! A hinged second door! You have never known such luxury.

The downforce on demand setup – the bit that makes it fond of ceilings – gets new fan blades and motors, and an on-board compressor so the under-skirt can be retracted. Other tweaks include increasing the ride height by 20 per cent (you can option in adaptive dampers if you want), fatter Michelins, and a hydraulic steering rack with F1-style valving.

It’s a mad, mad little device, this Spéirling. “The fastest thing we’ve ever driven,” no less. You’ll have to read our review to get yer head around how it actually works, but in short: lots of fans, lots of electricity, lots of witchcraft.

Naturally there’s lots of customisation on offer – what you’d expect from a car that costs £995k plus tax – from wheels, to paint and graphics and interior trim. And while it’s eligible for lots of global race events, it’s also eligible to just… pop down to your local trackday.

“In production form, the car is significantly more usable, but no less outrageous,” said boss Thomas Yates.

‘Outrageous.’ You want some quickfire stats? 0-60mph takes 1.55s. It can generate 3g. Go 190mph flat out. Deliver 1,000bhp to the rear wheels. Deliver 2,000kg of downforce from 0mph via a button. Drive flat out for between 25-31 miles “at LMP2 pace”. Recharge in just 20 mins depending on where you are. 

There’s air-con. The capacity to fit someone 6ft 7in tall. A kerbweight of 1,350kg and even traction control.

“In terms of exhilaration, grip, acceleration, sound, aesthetics and technology, we offer something that no other manufacturer is able to,” Yates added.
