Elaphe presents in-wheel motor for front wheels
It integrates large 400 mm brake discs in a 21-inch rim, making it ideal for the front wheels of high-performance vehicles where space and weight are crucial factors. The Sonic.1 delivers a continuous output of 200 kW per wheel in a 21-inch rim and achieves peak outputs of up to 255 kW. It offers a continuous torque of 1,000 Nm and a peak torque of 1,700 Nm per wheel. The maximum speed is 3,500 revolutions per minute (rpm).
Moreover, the Slovenian company states that with rear-wheel drive configurations, the Sonic.1 can offer up to 1 MW of power and 8 kW/kg continuous power density.
Elaphe’s Sonic.1 axle solution thus includes two of the above-mentioned in-wheel motors, as well as two 125kVA/L onboard SiC inverter by McLaren Applied. Moreover, thanks to ‘Elaphe Traction Control,’ the new in-wheel motor is said to enable 10 per cent faster acceleration and a 15 per cent shorter stopping distance compared to conventional e-axles. It also offers up to 15% higher vehicle lateral acceleration with torque vectoring.
The new in-wheel motor for front wheels is available for all-electric cars as well as for hybrids, says Elaphe.
Elaphe is displaying the Sonic.1 at the CES 2025, currently taking place in Las Vegas, USA. It teamed up with Italdesign, a renowned design company that is presenting the Quintessenza concept car. The latter features the in-wheel motor in all four wheels.
