Unleashing Power: The McMurtry Spéirling Hypercar
In the world of high-performance vehicles, the engine is the heart and soul. When it comes to hypercars like the McMurtry Spéirling, this concept reaches new extremes. Priced at £1 million, this electric hypercar is revolutionizing speed benchmarks, accelerating from 0 to 60 mph faster than almost any other production vehicle outside of drag racing. Behind this remarkable feat is not only a powerful fan system but also a pair of cutting-edge electric motors.
The McMurtry Spéirling’s fan system, known for its ability to allow the car to drive upside down, is complemented by two radial flux motors. These motors deliver a combined 1,000 bhp and 1,000 lb-ft of torque, making the car’s 0-60 mph sprint the fastest recorded by any production car.
Helix
Helix, the British motor supplier behind the Spéirling’s motors, is renowned for embedding compact yet powerful motors in some of the world’s most exotic vehicles. This includes not just the Spéirling but also Formula E race cars and high-performance models like the Lotus Evija and Aston Martin Valkyrie. Helix’s technology also reaches beyond automotive, contributing to developments in supersonic jets and marine propulsion systems.
For the Spéirling, Helix developed a custom drive system that includes two SPX242-94 motors paired with McMurtry’s gearbox. These motors are exceptionally light, each weighing 33 kg and providing 368 kW of power, equating to a power density of just over 11 kW/kg.

Despite its compact size of 150.2 inches in length, the Spéirling’s 1,300-kg body is capable of astonishing feats. Accompanied by dual 23,000-rpm fans, the vehicle can generate the necessary downforce to maintain grip at high speeds, making it a track powerhouse.
The Spéirling has already left its mark on the automotive world, setting records with its 1.55-second 0-60 mph time and 8-second quarter-mile. It also conquered world-famous tracks like the Top Gear Test Track and the Goodwood Hillclimb.
Helix
Helix’s involvement in the Spéirling project is just the tip of the iceberg. Their motors’ core technology is adaptable for various propulsion applications, from VTOLs to motorcycles, extending their reach across different industries. Helix continues to produce motors at its state-of-the-art facility in Milton Keynes, UK.
