This is a high-performance ERAD (Electric Rear Axle Drive) motor specifically designed for the Volvo XC90 T8 Twin Engine/Recharge plug-in hybrid. As a core component of Volvo’s SPA platform, this unit provides the essential electric propulsion for the rear wheels, enabling true eAWD capability and silent, zero-emission driving.

Product Overview

The ERAD is a compact, integrated electric drive unit that combines a high-speed electric motor with a reduction gearbox. It allows your XC90 T8 to operate in Pure Electric modefor daily commuting or provides a massive torque boost when combined with the petrol engine in Power mode.

Key Features & Benefits

• Seamless eAWD Performance: Delivers instant torque to the rear wheels without the need for a heavy mechanical driveshaft, improving weight distribution and efficiency.
• Precision Engineering: Designed to handle high-stress transitions between electric and hybrid power, reaching speeds of up to 12,500 RPM.
• Regenerative Efficiency: Acts as a high-capacity generator during braking, capturing kinetic energy to recharge the hybrid battery and extend your driving range.
• Direct Fitment: Manufactured to strict Volvo OEM specifications for perfect integration with the vehicle’s high-voltage cooling system and electronic control modules.
