High-Performance Brakes Meet In-Wheel Motors

Elaphe, a leader in in-wheel motor technology, has unveiled its revolutionary Sonic.1 front in-wheel motor at CES 2025. The Sonic.1 motor redefines electric and hybrid vehicle capabilities with unmatched power density, advanced wheel control, and seamless compatibility with high-performance brakes. This industry-first innovation integrates a 400 mm brake disc into a 21-inch rim, making it ideal for high-performance vehicles where space and weight are critical.

Key Highlights

  • Unmatched Power Density: Continuous output of 272 horsepower per wheel, with peak power reaching 347 HP in a lightweight design.
  • Brake System Integration: The first in-wheel motor to incorporate 400 mm high-performance front disc brakes in a 21-inch rim.
  • Enhanced Wheel Control: Delivers 20x faster response compared to conventional e-axle systems, improving handling, braking, and acceleration.
  • Scalable Design: Capable of supporting up to 1 MW axle peak power and 8 kW/kg continuous power density in rear-wheel configurations.
  • Vibroacoustics Technology: Patent-pending sound and vibration generation enhances driver feedback and emotions.

Advanced Technology and Design Innovation

The Sonic.1 motor features direct-drive functionality without gears, offering exceptional power density and efficiency. Its integration into the wheel optimizes space, weight, and performance, enhancing vehicle acceleration, stability, and braking. With its adaptable design, the Sonic.1 motor easily integrates into existing and future supercar models, opening new possibilities for aerodynamic and stylistic innovations.
