There’s a lot of eyes on electric hypercars right now, but the McMurtry Automotive Spéirling earns attention for a different reason: it’s small, track-focused, and brutally honest about how it makes its power. No massive cylinder counts or exaggerated numbers, just a compact single-seater that somehow produces 1,000 horsepower and uses it all. The secret isn’t just batteries. It’s motors. Very serious motors.
Those motors come from Helix, a UK company that has quietly spent the last two decades perfecting high-performance EV solutions. For the Spéirling, Helix developed a totally bespoke system using two SPX242-94 electric motors mounted at the rear, directly paired with McMurtry’s custom gearbox. Together, they deliver a combined 1,000 horsepower, but the real story is how efficiently and consistently that power is produced.
Each SPX242-94 motor weighs in at just 72 pounds yet delivers 368 lb-ft of torque. Instead of building a big, heavy EV and masking mass with brute force, McMurtry went the opposite direction: shrink everything, save weight everywhere, and rely on motors that punch far above their size. The result is an electric drivetrain that fits neatly inside a compact, single-seat chassis with hypercar performance.
Of course, power is only useful if you can put it down. That’s where McMurtry’s now-famous Downforce-on-Demand fan system comes into play. By actively pulling the car into the ground, the Spéirling allows Helix’s motors to unleash their torque immediately, without waiting for speed or aero buildup. That is how the car hits 0–60 mph in 1.5 seconds and why it’s rewritten record books at Goodwood Festival of Speed, Laguna Seca, and the Top Gear test track.
Helix’s motors are confirmed for the production Spéirling PURE, with customer deliveries planned for 2026. And through McMurtry Technology, the lessons learned here, fan downforce, compact e-axles, and high-performance battery systems, are being introduced to other manufacturers. In a world chasing bigger numbers, the Spéirling proves that smarter engineering still wins.
