The Kia EV4 Fastback offers a different approach to Kia’s electric expansion, standing alongside the Hatchback with a focus on elegance and aerodynamic refinement. Produced in Gwangmyeong, Korea, the Fastback takes Kia’s ‘Opposites United’ design philosophy in a sleeker direction while retaining the same performance-oriented electric platform.
Distinctive Aerodynamic Design
The EV4 Fastback carries a long-tail silhouette with a minimalist rear layout, designed to emphasise efficiency. Its drag coefficient drops to 0.23Cd, making it more aerodynamic than the Hatchback. The result is a design that signals refinement while improving energy efficiency at motorway speeds.
The front shares elements with the Hatchback, including the EV Tiger Face and Star Map lighting, but the Fastback’s proportions highlight smooth lines over sharp edges. Luggage space is also increased to 490 litres, making it the more practical choice for longer journeys.
Production and Market Role
Built at Kia’s Gwangmyeong EVO Plant, the EV4 Fastback complements European production of the Hatchback by expanding global availability. Its design, however, remains in line with expectations of the European market, focusing on a balance between aerodynamic efficiency and everyday practicality.
Driving and Handling Characteristics
The Fastback shares its chassis architecture with the Hatchback. This means MacPherson struts at the front, multi-link suspension at the rear, and European-tuned dynamics for stability. Engineers worked to ensure that despite its sleeker design, the Fastback delivers the same confident handling and cornering performance expected from the EV4 line-up.
Noise and vibration control have also been carefully refined, supported by hydro-G suspension bushings and advanced damper systems. The result is a smooth and quiet ride, with stability at higher speeds a clear priority.
Safety and Structural Protection
Like the Hatchback, the Fastback integrates a reinforced body structure with multi-load paths around the battery for impact protection. Side-impact resistance is boosted by a multi-rib rocker panel design, while the roof can withstand more than five times the car’s weight.
Advanced driver assistance systems are standard, including Forward Collision Avoidance Assist, Lane Keeping Assist, Blind-Spot Collision Avoidance Assist, and Highway Driving Assist. Navigation-based Smart Cruise Control and Remote Smart Parking Assist add more convenience to the driving experience.
Powertrain and Performance
The EV4 Fastback is available with the same two battery options as the Hatchback. The long-range 81.4kWh battery delivers up to 380 miles (WLTP), while the 58.3kWh standard pack offers a slightly shorter range but quicker charging capability. Both can charge from 10% to 80% in around 30 minutes.
A single 150kW front-mounted motor powers the Fastback, providing acceleration from 0 to 62mph in under 8 seconds and a top speed of 105mph. The aerodynamic gains of the Fastback further support its efficiency in long-distance driving.
Proven Battery Durability
Kia subjected the EV4 battery system to rigorous validation. Testing included a 110,000-kilometre accelerated road simulation and a demanding 10,000-kilometre Nürburgring programme, which confirmed a 95% State-of-Health even under high stress. This ensures the Fastback maintains long-term durability for owners.
Connected Technology and Charging
Integration with the Kia App extends the Fastback’s usability. Remote vehicle access, real-time charge monitoring, and AI-assisted updates are part of the ownership experience. In-car entertainment options, including streaming services, highlight Kia’s focus on digital integration.
With over one million public charging points available through Kia’s European charging partnerships, drivers can plan journeys with confidence. Vehicle-to-Load and Vehicle-to-Grid capabilities expand the Fastback’s functionality for both travel and lifestyle needs.
Summary
The Kia EV4 Fastback combines aerodynamic efficiency, extended range, and advanced safety with a sleek, refined design. With up to 380 miles of range, rapid charging, and a spacious interior, it complements the Hatchback by offering a more elegant take on electric mobility. For drivers prioritising efficiency and style, the Fastback provides a strong alternative within Kia’s growing EV portfolio.
