The McMurtry Spéirling continues to redefine the boundaries of electric performance, thanks in part to a partnership with Helix , the UK manufacturer known for producing some of the most power-dense electric motors in the world. Helix has developed a bespoke propulsion system for the Spéirling, featuring two SPX242-94 electric motors mounted at the rear of the compact single-seater hypercar. Together they deliver up to 1,000 horsepower , enabling extraordinary performance figures including 0–60 mph in just 1.5 seconds . Each motor weighs only 33 kilograms yet produces 500 Nm of torque , demonstrating the extreme power density that Helix has achieved through its advanced electric motor technology. The propulsion system works alongside McMurtry’s innovative Downforce-on-Demand™ fan system , which generates enormous levels of aerodynamic grip even at low speeds. This combination allows the Spéirling to deliver record-breaking performance on both road and track. The hypercar has alr...
