McMurtry Automotive has revealed the final production form of its Spéirling PURE, a single-seat electric track car that generates up to 2,000 kilograms (4,400 pounds) of downforce from a standstill using its fan-based Downforce-on-Demand system. The UK manufacturer says the production version carries 95% new components compared to prototype models, following a decade of development on the Spéirling PURE platform. Built at McMurtry’s factory in the Cotswolds, England, the car retails for £995,000 (~$1.3 million/~€1.15 million) plus local taxes, shipping and options, with customer deliveries beginning later in 2026.
Highlights
- Fan-based system produces up to 2,000 kg (4,400 lbs) of downforce from 0 mph, enabling 3g in corners and 3g under braking
- New 100 kWh Molicel lithium-ion battery — up from 60 kWh in prototypes — sends 1,000 bhp to the rear wheels for a 0-60 mph time of 1.55 seconds and a 190 mph top speed
- Wheelbase, width and length grow 10%, 14% and 11%, respectively, over prototype dimensions to fit the larger battery
- Price set at £995,000 plus taxes, shipping and options, with deliveries starting later in 2026
What Changed From Prototype to Production
McMurtry increased battery capacity to 100 kWh from 60 kWh, using Molicel P50B NCA 21700 cells in a standardized, modular pack designed for future upgrades. Regenerative braking recovery now reaches up to 200 kW at all states of charge, and new Helix drive motors add torque through an upgraded transmission. The company also relocated the powertrain cooling system from the rear to the front, which it says improves both efficiency and aerodynamics despite the car’s larger footprint.
A new carbon fiber monocoque, built to global motorsport safety standards, accommodates the bigger battery while adding cabin space, a wider door opening and a repositioned A-pillar for improved visibility. Wheelbase grew from 2 meters (6.6 ft) to 2.2 meters (7.2 ft), and the car gained a hinged secondary door, headlights for night running, and track-day safety features including turn signals and brake lights. Suspension articulation increased, ride height rises 20% when engaged, and the car now rides on off-the-shelf slick Michelin tires — 11% wider up front and 3% wider at the rear, with sidewalls raised 0.6 inches (15mm) for added compliance. McMurtry also swapped the electric power steering for a hydraulic, Formula 1-style setup for lighter feel and more driver feedback.
Downforce-on-Demand and Performance
Two high-speed fans, spinning at up to 23,000 rpm, draw air from a sealed region beneath the chassis to generate immediate downforce independent of vehicle speed. McMurtry says this differs from traditional wing- or diffuser-based downforce, which is direction-specific, and allows the Spéirling PURE to maintain grip and stop in a shorter distance even during a spin. The dual-fan setup is redundant by design, so the driver retains control if one unit has an issue. An onboard air compressor now lets the underbody skirt system retract independently for trailer loading and pit maneuvering — a function that required an external air bottle on prototypes.
Thomas Yates, McMurtry’s Co-founder and Managing Director, said the production Spéirling PURE is “significantly more usable, but no less outrageous” than its prototype, adding that customer feedback “helped us turn a record-breaking prototype into an extraordinary and highly usable track car.”
Ownership and Charging
McMurtry designed the production car around ease of ownership, saying it can be run at track days with just a driver and one other person, though a full factory support program is available. Access panels added to the monocoque and bodywork allow easier servicing, including emptying the fan filter cassette through the side pods. At tracks with high-speed charging infrastructure, the car can recharge from 20% to 95% in 20 to 60 minutes depending on temperature and charger output; McMurtry also offers an optional portable 100 kWh, 120 kW powerbank for charging at any venue. Customers work with an in-house designer during ordering to select wheel designs, graphics, paint and interior trim, with seats custom-molded to each owner in a process McMurtry compares to Le Mans prototype construction.

Pricing and Availability
The Spéirling PURE is priced at £995,000 (~$1.3 million/~€1.15 million) plus local taxes, shipping and options, with deliveries beginning later in 2026.

Company Background
McMurtry Automotive was founded in 2016 by the late Sir David McMurtry, inventor of the touch-trigger probe measurement device and founder of metrology supplier Renishaw plc, and Thomas Yates, an engineer he recruited from Mercedes F1’s High-Performance Powertrain division. The Spéirling prototype set a Goodwood Festival of Speed Hillclimb record in 2022 and broke the Top Gear Test Track record in 2025, previously held by a 2004 Renault Formula 1 car.
