McMurtry Spéirling PURE: The Electric Hypercar That Generates More Downforce Than Its Own Weight

The electric vehicle revolution has already rewritten the rules of acceleration, but McMurtry Automotive has gone several steps further. Its production-ready Spéirling PURE is not just another electric hypercar—it is arguably one of the most technologically advanced track machines ever created.

Following years of development and multiple record-breaking performances, McMurtry has unveiled the final production version of the Spéirling PURE, a single-seat electric hyper track car capable of producing up to 2,000 kg of downforce from 0 km/h—a figure that exceeds the car’s own weight. This revolutionary engineering enables Formula 1-level cornering and braking performance while remaining remarkably accessible for private owners. Around 95% of the vehicle has been redesigned compared with earlier prototypes, making it faster, more durable, and easier to own. (McMurtry Automotive)

A Fan Car Unlike Anything Else

Unlike conventional supercars that depend primarily on wings and aerodynamic surfaces to create downforce at high speeds, the Spéirling PURE uses McMurtry’s patented Downforce-on-Demand™ technology.

At the heart of the system are two high-speed fans spinning at approximately 23,000 rpm, which extract air from beneath the chassis to create a low-pressure zone underneath the car.

This suction literally pulls the vehicle onto the racing surface.

The result is astonishing:

• Up to 2,000 kg of downforce
• Available from 0 km/h
• Consistent grip even at low speeds
• Around 3g of cornering force
• Around 3g under braking

Because the downforce is mechanically generated rather than relying solely on airflow, the car enjoys maximum grip immediately after leaving the pit lane, during slow corners, and even in situations where traditional aerodynamic cars lose effectiveness. (McMurtry Automotive)

Performance That Challenges Formula Cars

The Spéirling PURE is powered by a pair of rear-mounted electric motors producing approximately 1,000 bhp, delivering power exclusively to the rear wheels through an electronically controlled differential.

Performance Specifications

The acceleration figure alone places it among the fastest production vehicles ever built.

However, McMurtry emphasizes that outright acceleration isn’t the biggest achievement.

The enormous grip allows drivers to carry incredible speed through corners while braking later than almost any other production car. (McMurtry Automotive)

A Completely Redesigned Production Car

Although it resembles earlier prototypes, the production Spéirling PURE is almost an entirely new machine.

McMurtry states that approximately 95% of the components are newly engineered, including:

• New carbon-fibre monocoque
• Larger chassis
• Longer wheelbase
• Improved cooling system
• Revised suspension geometry
• New gearbox
• New Helix electric motors
• Hydraulic power-assisted steering
• Wider Michelin slick tyres

The wheelbase has increased to 2.2 metres, primarily to accommodate a much larger battery pack while improving high-speed stability.

Bigger Battery, Longer Sessions

Prototype Spéirling models used a 60 kWh battery.

The production version upgrades to a 100 kWh Lithium-Ion battery using high-performance Molicel cylindrical cells.

Benefits include:

• Longer track sessions
• Improved thermal stability
• Higher regenerative braking capability
• Future modular battery upgrades

The battery enables approximately 40–50 km of continuous driving at LMP2 race pace, an impressive figure considering the extreme loads generated on a race circuit. Regenerative braking has also increased to 200 kW, helping recover energy during heavy braking.

Designed for Private Owners

Unlike many hypercars that require an entire race crew, McMurtry focused heavily on ease of ownership.

The company claims owners can operate the car during track days with only:

• One driver
• One assistant

Additional improvements include:

• Easier service access
• Improved fan filter maintenance
• Optional electronically adjustable dampers
• Air conditioning
• Custom-moulded driver’s seat
• Built-in storage for helmet and racing gear

Charging from 20% to 95% takes approximately 20–60 minutes, depending on charger output and ambient temperature. McMurtry also offers an optional portable 100 kWh, 120 kW battery powerbank for tracks without permanent DC fast charging infrastructure. (McMurtry Automotive)

Why 2,000 kg of Downforce Is So Important

Most performance cars generate meaningful downforce only at high speeds.

For example:

• Road-going supercars often produce a few hundred kilograms at top speed.
• GT3 race cars generate significant aerodynamic load but still rely heavily on vehicle speed.
• Formula One cars create enormous downforce, yet it also scales with speed.

The Spéirling PURE changes the equation by generating maximum downforce even while stationary.

This provides several advantages:

• Maximum tyre grip immediately
• Faster exits from slow corners
• Reduced wheelspin
• Shorter braking distances
• Exceptional stability
• Predictable handling across a wider speed range

This fan-assisted approach revives a concept made famous by historic “fan cars,” but McMurtry has modernized it with electric propulsion, advanced control software, and precision engineering. (McMurtry Automotive)

Record-Breaking Heritage

The Spéirling platform has already demonstrated its capabilities through several high-profile achievements before entering production.

Prototype versions have:

• Set the overall record at the Goodwood Festival of Speed hill climb.
• Broken the Top Gear Test Track lap record.
• Demonstrated the extraordinary capabilities of the fan-assisted downforce concept through multiple public performances. (McMurtry Automotive)

Pricing and Production

The Spéirling PURE is an ultra-exclusive machine.

Key production details include:

• Handmade in the United Kingdom
• Customer-specific customization
• Starting price of approximately £995,000 (before taxes and options)
• Customer deliveries scheduled during 2026

Owners can personalize colours, graphics, wheels, cockpit trim, and seating to create a truly bespoke machine.

Final Verdict

The McMurtry Spéirling PURE is more than just another electric hypercar—it represents a fundamental shift in performance engineering. While most manufacturers chase ever-higher horsepower figures, McMurtry has focused on something arguably more important: grip.

Its patented fan-driven Downforce-on-Demand™ system, delivering 2,000 kilograms of downforce from a standstill, gives the Spéirling PURE capabilities that were once reserved for elite motorsport. Combined with 1,000 bhp, a 100 kWh battery, 1.55-second 0–60 mph acceleration, and 3g cornering and braking forces, it stands among the most extreme track-focused production cars ever built.

For enthusiasts, engineers, and racers alike, the Spéirling PURE is a glimpse into the future of high-performance electric vehicles—where innovative aerodynamics matter just as much as raw power.
