The production version of the record-breaking McMurtry Speirling has arrived with a £995,000 price tag and a scheduled delivery date for the end of 2026.

Named the Speirling Pure, the interior of the British brand’s electric hyper track car remains true to the prototype, which twice claimed the Goodwood Festival of Speed’s outright hillclimb record with ex-Formula 1 driver Max Chilton behind the wheel.

Despite being visually similar inside and out to the gravity-defying prototype Speirling, the Pure is 95% new. A visual change is that its fan inlet ducts are now visible from the rear. What’s more, the single-seat cockpit can be trimmed with a variety of logos and in a broad selection of colours, strips, and stitching patterns.

Yet it’s under the Speirling Pure’s carbon-composite skin where the biggest technical changes have taken place.

The updates include extending the wheelbase from 2 metres to 2.2m to accommodate the new 100kWh battery pack, a hinged secondary door, and a swan neck-style rear wing with a boot compartment underneath for storing a helmet and a HANS device.

In terms of track day friendliness, headlights allow for evening/nighttime track running, while indicators, hazard lights, brake lights, and main beam flash are now also part of the package.

Like the McMurtry Speirling prototype, the Pure comes with the Cotswolds-based carmaker’s patented Downforce on Demand fan technology, which generates up to 2,000kg of downforce from 0mph and a maximum load of 3G in corners and under braking.

The Speirling Pure’s Downforce on Demand setup uses two high-speed fans beneath the chassis to suck the car to the ground. The production car’s system benefits from a new cooling design and has been relocated to lower the centre of gravity, while new fan blades improve durability.

Unlike the prototype, which requires an external air bottle, the McMurtry Speirling Pure gets an onboard air compressor as part of its Downforce of Demand package, meaning the skirt can be retracted independently for trailer loading and slow-speed manoeuvring.

McMurtry has designed the Speirling Pure to deliver a “plug and play experience”. Unlike other track day exotica, all it takes is a team of two to run it – a driver, and someone to plug it in. The car comes with a 120kW powerbank, and its 100kWh battery pack can be charged from 20-90% in anything from 20 minutes to an hour.

With a top speed of 190mph and a 0-60 mph time of 1.55 seconds, the McMurtry Speirling is eligible to compete in the USA’s Global Time Attack and the European Time Attack Masters. It can also participate in non-competitive, race-inspired events such as GT1 Sports Club.

Just 100 cars will be built, and each can be personalised with an array of wheel designs, graphics, and paint finishes. Owners will also benefit from membership of the McMurtry Owners’ Club, promising a variety of international track days throughout the year, plus support from the firm’s technicians and driver coaches.

The McMurtry Speirling Pure will be on display at next weekend’s Goodwood Festival of Speed and will make its track debut at The Quail in Monterey, California, on August 14. Alongside its FoS record, the Speirling claimed the fastest-ever time around the Top Gear test track. Last year, it became the world’s first car to drive upside down.
