Genesis has released technical details on the chassis control systems in its GV60 Magma performance EV. The all-wheel-drive electric vehicle combines torque vectoring, an electronic limited-slip differential, and a 400-millimeter brake package tuned across multiple drive modes. The company also introduced a dedicated Drift mode for controlled oversteer.
Highlights
- 400 mm disc brakes with monoblock calipers achieve a 100-0 km/h stopping distance of 33.8 meters
- Torque vectoring system integrates dual motors, a rear e-LSD, and brake-based vectoring for cornering stability
- Drive mode-specific brake feel adjusts pedal response and increases braking force by approximately 15% in Sport mode at high speeds
- New Drift mode uses dedicated torque vectoring logic and acceleration maps to enable sustained, controllable oversteer
Torque Vectoring and Drift Mode
The GV60 Magma’s torque vectoring system distributes power between front and rear motors. It actively manages understeer and oversteer during cornering. The rear-mounted electronic limited-slip differential (e-LSD) adjusts grip between inner and outer wheels as loads shift. Brake-based torque vectoring also responds to steering inputs during sharp turns.
The front-to-rear torque ratio ranges from 35:65 to 65:35. The e-LSD operates with an outer-to-inner torque ratio between 1:1 and 2.5. Each ESC mode carries its own calibration settings for the motors, e-LSD, and brakes.
“Genesis refined the system via rigorous winter testing in Sweden and New Zealand to ensure stable yet playful motion control, even on low-grip surfaces like snow,” said Gwichul Kim, Senior Research Engineer of the Genesis Chassis Test Team.
Drift Mode Operation
The dedicated Drift mode modifies torque distribution and throttle mapping. It uses drift-specific torque vectoring logic along with a unique acceleration map. As a result, the system produces sustained oversteer, allowing the driver to maintain vehicle attitude through a drift in the AWD electric platform.
Braking System Specifications
The GV60 Magma uses 400 mm disc brakes paired with monoblock calipers. A high-performance ABS system works alongside these components. Together, the setup stops the vehicle from 100 km/h in 33.8 meters.
Regenerative braking operates on both front and rear axles. It remains active even during hard braking and ABS engagement. According to Genesis, this approach reduces brake fade during sustained high-intensity use. A regenerative braking slip control function also maintains stability if wheels lose traction.
Drive Mode Brake Feel Tuning
Brake pedal feel changes between the GV60 Magma’s drive modes:
- Comfort mode: Smooth, linear pedal response with an initial free stroke zone designed for daily driving
- Sport mode: Free stroke eliminated; hydraulic control increased for immediate pedal response; braking force increased by approximately 15% at high speeds
The Sport mode calibration targets track-oriented driving conditions.
