The model introduces an expressive new design and generous exterior dimensions: 4,440mm long and 1,850mm wide, while its spacious interior offers passengers in the rear class-leading legroom (964mm) and plenty of headroom (973mm). Behind the rear seats, customers can make use of 438 litres of cargo space, making the model ideal for either transporting moving boxes or weekend trips.
The design turns heads with a distinctive floating roofline which slips elegantly into the rear hatch. Key design cues include the Star Map Signature Lighting inspired by the EV9, rear hidden door handles integrated into the C-pillar, and an exclusive Sparkling Yellow exterior colour. On top of this, the K4´s GT-Line looks even sportier. The trim features a three-spoke steering wheel, paddle shifters, 17-inch or 18-inch alloy wheels, gloss black mirror caps, side sills, and wheel arch mouldings.
The K4 carries forward Kia’s commitment to offering customers a diverse range of propulsion options. This includes electrified powertrains to ease the transition to electric mobility. Of the five available powertrains in Europe, two are electrified, aligning with Kia’s broader electrification strategy.
The powertrain offering starts with a 1.0-litre T-GDi petrol engine (115PS) with a six-speed manual transmission. This engine is also available with mild-hybrid technology. Customers who opt for the mild-hybrid engine can pair it with a seven-speed dual-clutch automatic transmission instead. The 1.6-litre T-GDi petrol engine comes with a seven-speed dual-clutch automatic transmission (150/180PS). Later in 2026, the powertrain line-up will be expanded to include a full hybrid option.
The K4 boasts one of the most advanced technological offerings in its class. A panoramic display integrates a 12.3-inch instrument cluster, a 5.3-inch climate display, and a 12.3-inch touchscreen infotainment screen. The Connected Car Navigation Cockpit (ccNC) system unites navigation, multimedia, and vehicle settings control into a single, intuitive interface. Wireless Apple CarPlay™ and Android Auto™ are standard across all trims with a wireless phone charger available in higher trims.
A Harman Kardon® premium audio system transforms the cabin into a personal concert hall. Comfort is further enhanced with heated and ventilated front seats wrapped in stylish, black bio-based artificial leather upholstery.
The Digital Key 2.0 with ultra-wideband technology allows compatible smartphones to function as virtual keys. At the same time, Kia Connect services offer a range of digital tools, such as over-the-air (OTA) updates, music streaming, and Wi-Fi hotspot capability. With its AI-powered voice assistant, drivers can simply say “Hey Kia” to control various features or get information, including help with the owner’s manual or local recommendations.
The K4 will be produced at the company’s new plant in Mexico, with models expected to arrive in UK showrooms in the fourth quarter of 2025. Full UK pricing and specifications will be announced closer to its on-sale date.
