Kia has officially announced UK pricing and specifications for the all-new EV4 Fastback, the sleek, four-door saloon version of the EV4 electric vehicle. Starting at £40,895 on-the-road (OTR), the EV4 Fastback delivers up to 380 miles of electric range on a single charge and will be offered exclusively in ‘GT-Line’ and ‘GT-Line S’ trims. UK customer deliveries are set to begin in autumn 2025.
The EV4 Fastback is Kia’s first-ever four-door electric saloon, extending the brand’s acclaimed EV line-up into a new market segment and building on Kia’s commitment to launch 15 fully electric models globally by 2030.
Design and Dimensions: Aerodynamic Fastback Styling
The EV4 Fastback stands out with a sleek saloon silhouette that’s 300mm longer and 5mm lower than the EV4 hatchback. The extended rear overhang enhances its coupe-like roofline, while maintaining 490 litres of boot space for everyday practicality.
Aerodynamic efficiency is a core focus. The EV4 Fastback boasts a 0.23Cd drag coefficient, thanks to:
- Active Air Flaps integrated into the front bumper
- 82.5% underbody coverage with a full-body undercover
- Smooth boattail design for minimal drag
These elements not only enhance range but also give the EV4 Fastback its distinct, futuristic look.
Dimensions (EV4 Fastback):
- Length: 4,730mm
- Width: 1,860mm
- Height: 1,480mm
- Wheelbase: 2,820mm

Performance and Range: 380 Miles of Zero-Emission Driving
Both the EV4 Fastback GT-Line and GT-Line S are powered by Kia’s 81.4kWh long-range battery, paired with a 150kW (201bhp) front-mounted electric motor producing 283Nm of torque.
- Range (WLTP): Up to 380 miles per charge
- 0–62mph: 7.9 seconds
- Top Speed: 105mph
Thanks to Kia’s 400V E-GMP platform, the EV4 Fastback supports ultra-fast charging:
- 10–80% charge in 29 minutes (31 minutes for long-range models) via a 350kW DC charger
- 5 hours 20 minutes on an 11kW AC charger (7 hours 15 minutes for long-range models)
High-Tech Cabin: AI Assistant and Theatre Mode
Inside, the EV4 Fastback features Kia’s latest connected car Navigation Cockpit (ccNC), displayed across dual 12.3-inch screens with an additional 5.3-inch climate touchscreen. Wireless Apple CarPlay™ and Android Auto™ come as standard, alongside Kia Connect with seven years of complimentary services.
A standout innovation is the Kia AI Assistant powered by ChatGPT. Activated by “Hey Kia”, it can:
- Control in-car functions via natural conversation
- Plan journeys and suggest points of interest
- Answer FAQs about the vehicle
- Entertain with jokes, trivia, or music recommendations
‘GT-Line S’ models also feature premium front relaxation seats, ideal for resting while charging, as well as two unique cabin modes:
