The 2027 Alpha S5 supports 5C charging, with Arcfox stating that the battery can charge from 30% to 80% in 8.9 minutes. The company also claims that 15 minutes of charging can add up to 560 km of range.
Actual charging performance and driving range can vary with battery temperature, charging infrastructure, driving conditions and other factors. The battery’s exact capacity and the maximum charging power in kilowatts have not been specified in the available information.
Dimensions and Aerodynamics
The updated Alpha S5 retains the exterior dimensions of the current model introduced in March.
| Dimension or Exterior Specification | Measurement |
|---|---|
| Length | 4,886 mm |
| Width | 1,930 mm |
| Height | 1,480 mm |
| Wheelbase | 2,900 mm |
| Drag coefficient | 0.1925 |
| Front trunk (frunk) capacity | 148 liters |
| Exterior color options | 7 |
| Interior color schemes | 3 |
The sedan’s drag coefficient of 0.1925 reflects its aerodynamic design. The addition of a 148-liter front trunk provides extra storage space alongside the main luggage compartment, whose capacity has not been specified in the supplied information.
LiDAR and Driver-Assistance Technology
LiDAR is standard across all three 2027 Alpha S5 battery-electric variants. The sensor package combines a 192-channel LiDAR unit with millimeter-wave radar, ultrasonic sensors and high-definition cameras.
| Driver-Assistance Hardware | Specification |
|---|---|
| LiDAR | 192-channel, standard across the lineup |
| Millimeter-wave radars | 3 |
| Ultrasonic sensors | 12 |
| High-definition cameras | 7 |
