McMurtry Automotive initiates a new era of automotive performance as it reveals the production form of its single-seater, electric hyper track car - the Spéirling PURE - ready for owners to experience.

Designed from the outset in the name of unfiltered driving exhilaration and fun, and with 95% new components compared to prototype models, the Spéirling PURE delivers truly accessible F1-level performance that any driver can enjoy, with a strong focus on a plug-and-play ownership experience.

Following a decade-long research and development programme, during which Spéirling prototypes have accumulated thousands of kilometres in testing, McMurtry has leveraged its engineering creativity and worked outside of ‘industry norms’ to create a track vehicle that is unlike anything else in the automotive world.

McMurtry first captured global attention in 2022 when the Spéirling prototype set a new Goodwood Festival of Speed Hillclimb record - beating many established manufacturers before it. In 2025, it shattered the Top Gear Test Track record, once held by the 2004 Renault F1 car. That same year, the Spéirling prototype broke new ground to become the first car to ever drive upside down.

Thomas Yates, McMurtry’s Co-founder and Managing Director, comments:
“The Spéirling PURE marks the beginning of a new era in track driving with mind-bending performance to suit all levels of owner, from weekend enthusiasts to professional drivers. In production form, the car is significantly more usable, but no less outrageous. In terms of exhilaration, grip, acceleration, sound, aesthetics and technology, we offer something that no other manufacturer is able to.

“Less than ten years ago, there were just a handful of us with the brief and ambition to create a car company. We’ve come an awfully long way since then, patenting revolutionary new technologies, gathering a world-class team of talented individuals and raising the bar in the performance vehicle sector.

“Feedback from our earliest Spéirling PURE deposit holders has been instrumental in shaping our final customer offering. They recognised our vision, and their input has helped us turn a record-breaking prototype into an extraordinary and highly usable track car that people can own and enjoy. This final form is not just the result of our engineering ambition, but also the result of listening intently to the people who are going to drive it.

“Designed and built by hand at our new state-of-the-art factory in the Cotswolds, England, later this year we’ll be handing over the first Spéirling PURE to customers. We cannot wait to see what owners across the globe achieve in their cars, but rest assured, we also have some big plans of our own…"

What’s new from prototype to production
In production form, the Spéirling PURE represents the culmination of relentless research and development to produce a hyper track car that comprises 95% new components compared to prototype models. Improvements made from prototype models include:

Powertrain

• An increased battery capacity - now 100kWh, up from 60kWh batteries used in prototypes - to improve overall running time, using Molicel P50B NCA 21700 cells.
• A standardised, modular McMurtry battery design with futureproofing built in for evolution upgrades.
• Increased regenerative braking energy recovery, up to 200kW at all states of charge.
• New Helix drive motors with additional torque, mated to an upgraded gearbox.
• Moving the powertrain cooling system from the rear to the front of the car, bringing dual benefits in efficiency and aerodynamics. Despite the production-spec Spéirling PURE growing slightly in size to accommodate a larger 100kWh battery, airflow across the car and through its rear tunnels is much cleaner.

Chassis and Bodywork

• New exterior and interior designs, staying true to the original Spéirling philosophy.
• New carbon fibre monocoque designed to meet global motorsport safety standards. Accommodates larger battery, enhances cabin space with more elbow and leg room, improves ingress/egress via wider door opening, with a repositioned A-pillar for a wider field of view.
• Increased wheel base from 2m to 2.2m to accommodate the new 100 kWh battery.
• Secondary door now hinged, with wider hinge spacing further aiding ingress/egress.
• A swan-neck style rear wing, incorporating a boot compartment underneath for a helmet and HANS device.
• Headlights to allow for evening/nighttime track running.
• Track day safety features including indicators, hazard lights, brake lights and main beam flash.

Downforce-on-Demand^TM System

• New fan blades for enhanced durability.
• New fan motors and cooling design, plus overall assembly position relocation to improve centre of gravity.
• Under-car downforce skirt durability and travel improvements, able to perform for thousands of kilometres.
• An onboard air compressor as part of the Downforce-on-Demand^TM skirt system. The skirt can be retracted independently for trailer loading and slow-speed manoeuvring, such as when in the pits. Spéirling prototypes required an external air bottle to pre-charge the system.

Suspension and Steering

• Increased suspension articulation, also with nominal ride height increase of 20% when in use.
• 11% wider front and 3% wider rear off-the-shelf slick Michelin tyres. Increased sidewall height by 15mm front and rear to improve compliance.
• Electric power steering system replaced by a hydraulic power-assisted steering system with Formula 1-style valving for lighter steering and increased driver feedback.
• Electronically-adjustable dampers as an optional extra.

Performance explained with Downforce-on-Demand^TM
The Spéirling PURE delivers a totally unique driving experience via McMurtry’s patented, revolutionary Downforce-on-Demand^TM technology. This system produces up to 2,000kg of downforce from 0mph, instilling absolute confidence in drivers to push the car to its limits at 3g in corners and at 3g under braking.

Two high-speed fans generate immense suction beneath the Spéirling PURE, effectively pulling it onto the road surface – much like a giant, highly controlled vacuum. With bespoke fans spinning at up to 23,000 rpm, the fans draw air from a sealed region beneath the chassis through filters, creating immediate and consistent downforce. As air is expelled from the rear, the Spéirling produces a sound more commonly associated with a jet engine than an electric vehicle - a striking contrast to the near-silence typically expected from EVs.

The system uses dual fans for built-in redundancy, ensuring that even in the highly unlikely event of an issue with one unit, the driver can retain control of the car. Unlike traditional downforce that is primarily generated by direction-specific airflow over wings or under diffusers, the Spéirling PURE maintains downforce in the event of a spin, allowing drivers to come to a controlled stop in a much shorter distance.

New exterior and interior design
The exterior design of the production-spec Spéirling PURE sees significant changes from prototype models, yet the McMurtry design team focused on maintaining the car’s unique stance and proportions.

The car’s wheelbase (+10%), width (+14%) and length (+11%) have increased to accommodate the larger battery and onboard systems, but the car still fundamentally remains a small vehicle. New carbon fibre bodywork has been sculpted around these new dimensions.

Relocating the Downforce-on-Demand^TM fan system has reduced the centre of gravity and allowed the fan inlet ducting to be visible - a unique design element.

The Spéirling PURE’s interior has taken a significant step beyond purely functional design to become a more refined and sophisticated environment. Each seat is uniquely tailored to its owner - custom-moulded in a process similar to that used in Le Mans prototypes - ensuring a precise fit that provides exceptional comfort, support, and crucially, a strong connection to the car. A range of option colours, stitching, stripes and logos can be selected for the seat, steering wheel and dashboard trim.

A bespoke racing-style steering wheel has been engineered to provide intuitive access to key controls while driving at speed, with a fan rev paddle for pitlane fun. A central screen delivers instantly legible graphics for key information such as power and fan settings, state of charge, speed and temperatures to inspire confidence behind the wheel.

A seamless ownership experience
Vehicles capable of extreme performance are synonymous with being difficult to service and complicated to run - detracting from the enjoyment of ownership. The Spéirling PURE breaks this trend, being designed from the outset to provide owners with a straightforward, plug-and-play experience.

With just a driver and a competent friend, the Spéirling PURE can be run at track days or competitive events - a stark contrast from what is required to run other ultra high-performance track vehicles. If owners desire, however, a full factory support programme is available to make running a Spéirling PURE seamless.

With many global race tracks now home to high-speed charging infrastructure, the Spéirling PURE can be recharged from 20%-95% in 20-60 minutes depending on ambient temperature and charger power. As an optional extra, McMurtry has developed a portable 100kWh storage, 120kW output powerbank to allow Spéirling PURE charging at any venue. The powerbank itself can be charged by any conventional three-phase pit garage source.

Access panels have also been added to the monocoque and bodywork, meaning when fully assembled, the Spéirling PURE can be serviced at far greater ease, with key components easily accessible.  An example is emptying the fan filter cassette via quick access panels in the side pods.

Unique customisation
An extensive options programme gives customers the opportunity to make each Spéirling PURE truly their own. During the order process, customers collaborate with an in-house designer to create a highly personalised specification, choosing from an array of wheel designs, unique graphics and paint finishes, to bespoke interior trim. No two cars will be the same.

Competing in the Spéirling PURE
The Spéirling PURE is eligible for competition in events such as Global Time Attack in the USA and European Time Attack Masters at the Nürburgring. Non-competitive but race-inspired events, such as GT1 Sports Club, are also recommended.

Origins
Named after the Gaelic word for ‘thunderstorm’, the Spéirling PURE is the brainchild of the late Irish engineering pioneer, Sir David McMurtry, and former-Formula 1 engineer, Thomas Yates.

As the inventor of the globally ubiquitous touch trigger probe measurement device and founder of Renishaw plc - the UK’s largest metrology equipment supplier - Sir David hand-picked Thomas Yates from Mercedes F1’s High-Performance Powertrain division to establish McMurtry Automotive in 2016 with the goal of making a new form of vehicle, going against the industry’s direction of bigger and heavier cars. To put the McMurtry name on the map, they revived and modernised fan car downforce technology inspired by the successful 1970s Can-Am and Formula 1 fan cars and built the Spéirling around it.

Where to see the Spéirling PURE next
A Spéirling PURE will be creatively displayed at the Goodwood Festival of Speed next week, 9-12 July.

The car will make its official public debut in full production form at The Quail in Monterey, California, next month on 14 August.
