- Alpine unveils patented Active Torque Vectoring for A390 all-electric sports fastback
- System distributes 0–100% of torque between rear wheels for unmatched agility
- Three-motor layout enables ultra-fast, independent rear torque control
- Delivers sub-4-second 0–100 km/h acceleration and exceptional cornering stability
The Alpine A390 marks a major leap in electric performance engineering. The all-new fastback sports car introduces Alpine Active Torque Vectoring, a patented system developed over five years to redefine handling precision and driver engagement in an electric platform.
A New Benchmark in Electric Dynamics
Powered by a three-motor setup—one on the front axle and two at the rear—the A390 delivers over 400 hp and 800 Nm of torque. This configuration not only provides all-wheel drive but also allows Alpine’s engineers to manage rear-wheel torque distribution with unprecedented precision.
Control systems engineer Constance Leraud-Reyser describes the innovation as “a step beyond conventional limited-slip differentials,” enabling real-time torque modulation between the two rear wheels. The result is sharper handling, enhanced stability, and a driving experience that belies the vehicle’s size and weight.
Instantaneous Torque Control for Every Situation
The Active Torque Vectoring system adjusts within milliseconds, continuously responding to steering angle, vehicle speed, and traction conditions. Whether accelerating, cornering, or driving straight, the A390 dynamically corrects understeer or oversteer tendencies, ensuring a neutral, agile balance.
When traction loss occurs—such as on a slippery surface—the system automatically redirects torque to maintain grip. Drivers can monitor system activity in real time via the Alpine Telemetrics Live Data display.
Complementary Systems and Driving Modes
Torque distribution is managed by three integrated systems:
- Alpine Torque Pre-Control for initial traction management
- e-AWD for front-to-rear torque balance
- Active Torque Vectoring for left-to-right rear control
Five selectable driving modes—Save, Normal, Sport, Personalised, and Track—allow drivers to fine-tune dynamics from efficiency to maximum agility.
“Thanks to Active Torque Vectoring, the A390 is as nimble and intuitive as the A110,” notes Leraud-Reyser. “Despite its power, it remains remarkably easy to drive.”
