Gateshead, U.K., & Atlanta, Nov. 04, 2025 (GLOBE NEWSWIRE) -- Turntide Technologies (Turntide), a leader of best-in-class electric motors, power electronics, and energy storage, and Hypercraft, a provider of OEM-grade hybrid and electric powertrain systems, unveiled a new customer vehicle, the Sierra Echo-S powered by Turntide axial flux motor technology at SEMA in Las Vegas, Nevada. The revolutionary Echo-S delivers an unprecedented driving experience, ushering in a new era of performance torque and efficiency in the off-road vehicle industry.
The introduction of axial flux motor technology marks a breakthrough moment for the off-road industry. While electric power is not new to the trail, Turntide’s axial flux motor takes performance to the next level and can deliver higher torque, greater efficiency, and lighter weight in a compact form, unlocking new opportunities for both manufacturers and enthusiasts.
“Turntide’s axial flux motor delivers huge power in a small, light package that allows us to push the limits of what off-road vehicles can do,” said Jake Hawksworth, CEO of Hypercraft. “Turntide has been a true partner every step of the way.”
While axial flux motors are relatively new to the off-road industry, they are well-established and proven in the on-road, commercial, off-highway, marine, and premium automotive sectors because of their high performance, flexibility, and scalability. Turntide and Hypercraft chose two Turntide AF 140 motors (each motor weighs only 42 kg) and paired each with a Turntide Gen 5, Size 9 inverter to crank up the torque and efficiency of the Sierra Echo-S power system. The vehicle’s performance (numbers are for one motor) includes:
- Continuous torque: 247 Newton meters (Nm)
- Peak torque: 610 Nm
- Continuous power: 67 kilowatts (kW)
- Peak power: 182 kW
This powerful combination ensures that the Sierra Echo-S delivers an exhilarating driving experience with precision in the most extreme environments.
“Working with Hypercraft to bring this off-road vehicle to life has been an adventure,” said Jason Glass, North America Business Development Director. “We worked with the Hypercraft team to ensure that the axial flux motor, inverter, and differential function together to provide excellent performance. We are excited to have an incredible car for customers and media to test drive early next year and experience the potential of our technology.”
