Sleek Efficiency and Modern Flair: A Review of the 2026 Kia EV4 Fastback [EU]

The electric vehicle landscape in Europe is becoming a fiercely contested arena, and Kia, a veteran of electrification, is poised to make a compelling statement with the 2026 EV4 Fastback. Sitting below the acclaimed EV6, the EV4 Fastback arrives not as an SUV, but as a sleek, aerodynamically-optimised saloon-style model, blending bold, futuristic design with a focus on range and everyday usability that should resonate strongly with European buyers.

While the market also receives a slightly more upright EV4 Hatchback, the Fastback variant—with its long-tail silhouette—is the design that truly captures attention and leverages maximum efficiency. Built on the brand's renowned Electric Global Modular Platform (E-GMP), the EV4 Fastback is set to challenge established rivals like the Hyundai Ioniq 6 and the segment-defining Tesla Model 3.

Design: Polarising Lines and Aerodynamic Grace

Kia's "Opposites United" design philosophy is in full effect, but nowhere is it better executed for aerodynamic performance than on the Fastback. Measuring approximately 4,730mm in length, the EV4 Fastback is a substantial car, comparable to a BMW 3 Series. Its low bonnet, raked windscreen, and dramatic, sloping roofline—the element that gives it the "Fastback" moniker—taper smoothly into a minimalist rear deck. This shape achieves an impressive drag coefficient of $0.23\text{ Cd}$, making it incredibly slippery and a key factor in its excellent range.

The front end is instantly identifiable as a member of the Kia EV family, featuring the "EV Tiger Face" and distinctive vertically oriented headlamps with the "Star Map" lighting signature pushed to the extremities. While the design is undoubtedly bold and may divide opinion, it manages to look both futuristic and refined, steering away from the more overtly technical look of some competitors. Flush-fitting door handles and a unique roof spoiler complete the highly efficient, elegant profile.

Interior: A Sanctuary of Space and Tech

Step inside the EV4 Fastback, and the cabin immediately impresses with its quality, space, and technology. Kia has delivered an interior that feels premium without resorting to excessive minimalism. The highlight is the panoramic curved display, which seamlessly integrates a $12.3\text{-inch}$ digital gauge cluster and a $12.3\text{-inch}$ infotainment touchscreen, all housed within a floating $30\text{-inch}$ glass panel that stretches across the dashboard.

Crucially, Kia has maintained a sensible approach to controls. While the large screen manages the bulk of the infotainment (powered by Kia's latest Connected Car Navigation Cockpit - ccNC), dedicated physical toggles and a $5.3\text{-inch}$ touch panel remain for critical climate control functions, alongside proper buttons for features like heated seats and the heated steering wheel. This blend of cutting-edge tech and tactile usability is a clear win for driver convenience.

Passenger comfort is another strength. Thanks to the EV-specific E-GMP platform, the cabin is generously proportioned. Legroom is ample in both rows, and even with the Fastback's sloping roofline, headroom remains acceptable. The front seats are of the popular 'relaxation' variety, offering pop-up leg rests for lounging during charging stops. The flat floor enhances rear passenger comfort, particularly for the middle seat occupant.

Practicality is also strong for the segment. The Fastback boasts a competitive luggage capacity of $490$ litres, surpassing its Hatchback sibling. This deep boot, while having a slightly narrow aperture due to the saloon-style lid, is capacious enough for serious road trips.

Performance, Range, and Charging

The EV4 Fastback is offered with a choice of two battery packs: a standard $58.3\text{ kWh}$ unit and a larger, long-range $81.4\text{ kWh}$ pack. Both are paired with a single $150\text{ kW}$ ($204\text{ hp}$) electric motor driving the front wheels, providing $283\text{ Nm}$ of torque.

The emphasis here is on efficiency and range, not outright blistering performance. The $0\text{-}100\text{ km/h}$ sprint takes a respectable $7.7$ seconds for the long-range model, a figure that feels brisk and sufficient for everyday driving. The true headline, however, is the projected driving range. The standard battery is expected to deliver a WLTP range of approximately $456\text{ km}$, while the long-range $81.4\text{ kWh}$ model pushes that figure up to a class-leading target of around $630\text{ kilometres}$ (WLTP). This substantial range makes the EV4 Fastback a genuinely viable long-distance tourer in Europe.

Based on the $400\text{V}$ architecture of the E-GMP platform, charging capabilities are fast, if not quite as rapid as the $800\text{V}$ systems of the EV6. When connected to a $350\text{ kW}$ DC fast charger, the battery can replenish from $10\%$ to $80\%$ in approximately $29$ to $31$ minutes, a performance that minimises road trip downtime. The car also features Vehicle-to-Load (V2L) capability, allowing owners to power external devices, adding a layer of utility.

Driving Dynamics: Comfort Meets Confidence

Kia has tuned the EV4 Fastback's suspension specifically for European roads. It features a sophisticated setup with MacPherson struts at the front and multi-link suspension at the rear, utilising frequency-reactive dampers. The result is a ride that is notably refined and comfortable, particularly over smooth motorway surfaces. This comfort doesn’t come at the total expense of handling; while the steering feel is on the lighter side in the Normal driving mode, the car remains composed and stable when cornering, offering a confident and controlled driving experience.

For those desiring a sharper feel, the top-tier GT-Line trim adds more assertive styling and is expected to come exclusively with the long-range battery, likely offering a sportier suspension tune to enhance dynamic responsiveness.

Verdict

The 2026 Kia EV4 Fastback arrives as a formidable contender in the compact electric saloon segment. It masterfully combines a head-turning, aerodynamically optimised design with an interior that is spacious, high-tech, and user-friendly.

Its headline-grabbing $630\text{ km}$ WLTP range, coupled with competitive charging times, positions it as one of the most practical EVs for European drivers. While the performance, in the initial front-wheel-drive configuration, is more than adequate rather than exhilarating, the overall package—quality build, cutting-edge tech, impressive efficiency, and ample space—makes the EV4 Fastback a highly appealing proposition.

For the European market, where efficiency and usable range are paramount, the EV4 Fastback isn't just a stylish alternative; it’s a smart, efficient, and technologically advanced new benchmark. Kia has once again proven its capacity to deliver compelling electric mobility that is poised for high sales success.
