Alpine has confirmed the pricing and technical specifications for the all-new A390, an electric sport fastback priced from £61,390. The platform integrates a tri-motor configuration with Active Torque Vectoring to manage the vehicle’s 470PS output, supported by a high-performance braking system utilizing 6-piston monobloc calipers across the entire range. UK orders open in early 2026 with first deliveries scheduled for spring.
Highlights
- Chassis Control: Standard Active Torque Vectoring utilizes two independent rear electric motors to precisely control torque at each wheel, optimizing yaw and agility.
- Friction Braking: All models feature Alpine-branded 6-piston monobloc front brake calipers as standard equipment.
- Tire Specification: The flagship GTS is fitted with Michelin Pilot Sport 4S tires on 21-inch forged wheels for maximum mechanical grip.
- Safety Tech: The ADAS suite includes automatic urban and interurban emergency braking with detection for cars, pedestrians, cyclists, and junctions.
Active Torque Vectoring and Chassis Dynamics
The A390 distinguishes itself in the segment through a dedicated focus on chassis dynamics rather than software-simulated feel. The architecture employs a tri-motor setup, placing one motor on the front axle and two independent motors on the rear. This configuration enables Alpine’s unique Active Torque Vectoring system, which actively manages torque distribution between the rear wheels to enhance cornering balance and responsiveness.
Development teams benchmarked the vehicle’s dynamic behavior against the significantly lighter A110 to ensure the 2,124kg curb weight does not compromise agility. The chassis specification is further bolstered by a suspension system utilizing hydraulic bump stops to manage vertical load and ride quality.
Braking Hardware and Wheel Assemblies
To manage the kinetic energy of the 470PS powertrain, Alpine has standardized robust friction braking hardware. Every A390 is equipped with 6-piston monobloc front brake calipers. The finish of these components varies by trim: the GT features anodized branded calipers, the Premiere Edition utilizes Bleu Alpine, and the GTS sports Rouge Racing calipers.
Tire selection is split by performance tier to optimize braking distances and handling. The GT model rides on 20-inch “CRISTAL” alloy wheels wrapped in Michelin Sport EV tires (245/45 R20). The high-performance GTS upgrades to 21-inch “SNOWFLAKE” diamond-cut forged wheels fitted with Michelin Pilot Sport 4S rubber (245/40 ZR21).
Advanced Driver Assistance Systems (ADAS)
The braking system is fully integrated with a comprehensive suite of active safety technologies. Standard features include intelligent adaptive cruise control, emergency brake assist, and advanced distraction recognition with emergency stop assist.
Crucially for urban safety, the platform utilizes automatic emergency braking capable of detecting cars, pedestrians, cyclists, and junctions in both urban and interurban environments. Additional stopping support is provided by reverse pedestrian warning and reverse parking exit warning systems.
