UK-based electric motor manufacturer Helix has developed a custom dual-motor propulsion system for the highly anticipated McMurtry Spéirling, the single-seater electric fan hypercar renowned for its record-breaking performance at circuits like Goodwood and Laguna Seca. Customer deliveries of this groundbreaking production vehicle are slated to commence in 2026.
Propulsion System Details
The bespoke system features two Helix SPX242-94 motors integrated at the rear of the Spéirling, delivering an impressive combined output of 1,000 horsepower and 1,000 Newton-meters of torque. Each individual motor is capable of producing 500 Newton-meters of torque while weighing a mere 33 kilograms. This compact design was specifically engineered to fit within the Spéirling’s constrained single-seater architecture, complementing McMurtry’s innovative fan-based downforce system. The motors are coupled with McMurtry’s proprietary gearbox.
Performance Benchmarks
The McMurtry Spéirling boasts remarkable acceleration figures, achieving 0-60 mph in just 1.5 seconds and completing a quarter mile in eight seconds. The hypercar has also set the fastest lap time ever recorded on the Top Gear test track, underscoring its exceptional performance capabilities.
Industry Recognition and Collaboration
Simon Mead, automotive chief engineer at Helix, commented on the collaboration, stating, “The McMurtry Spéirling demonstrates one of the most effective applications of advanced electric motor technology. We are proud to have been involved in its journey from an early stage, with Helix drive motor propulsion systems featuring throughout the evolution of this groundbreaking hypercar, from prototype to production.”
Helix has a proven track record in high-performance electric propulsion, having previously supplied systems for Formula E racing and other hypercars, including the Aston Martin Valkyrie, Lotus Evija, and Czinger 21C.
