INTRODUCING THE SPEIRLING PURE - A TRACK CAR REVOLUTION
The McMurtry Speirling Pure is the first commercially available sealed-skirt fan car in history: a 1,000 hp all-electric track machine that generates 4,400 pounds of downforce without a single traditional wing, priced from around 1 million pounds and limited to 100 units. It is the road-going evolution of the Speirling prototype that shattered the Goodwood Festival of Speed hillclimb record in 2022 with a time of 39.08 seconds.
What Is a Fan Car and Why Does It Matter?
The Speirling Pure generates its extraordinary downforce through a large electric fan housed beneath the car. This sealed-skirt system creates a low-pressure zone under the body, sucking the car onto the track surface and producing mechanical grip levels far beyond what conventional wings can achieve at accessible road speeds. In practical terms, the Speirling Pure corners at up to 3G, a figure associated with Formula 1 cars, yet it does so at speeds that a competent track day driver can manage. The concept was first explored in Formula 1 during the late 1970s and subsequently banned, making the Speirling Pure the first production machine to commercialise this technology legally for circuit use.
Speirling Pure Specifications and Performance
The Speirling Pure weighs under 1,000 kg and produces over 1,000 PS (735 kW) from its all-electric powertrain. The top speed is rated at 190 mph (306 km/h). Compared to the Goodwood record-setter, the Pure gains wider tyres, an enhanced powertrain, improved cooling, and a chassis extended by 10 inches (254 mm) to accommodate drivers up to 6 feet 7 inches tall. Where the record car was built for a single maximum-effort sprint, the Pure is engineered for multiple consecutive laps, with a larger battery pack calibrated for endurance rather than outright peak performance. McMurtry opened order books at the 2023 Goodwood Festival of Speed, where the Pure made its global public debut.
Why the Speirling Pure Is a Landmark in Electric Performance Cars
Every benchmark electric track car to date has relied on conventional aerodynamic devices: large wings, diffusers, and complex underfloor channels. The Speirling Pure renders most of those solutions secondary by generating its primary downforce mechanically rather than aerodynamically. This means the car can achieve extraordinary grip at lower speeds, making its performance envelope more accessible to a broader range of drivers. The all-electric powertrain delivers instant torque with none of the thermal lag that affects combustion-powered track cars, while regenerative braking through the fan system recovers energy on every deceleration. McMurtry expects to begin production deliveries in 2025, with 100 units allocated across a global waiting list.
