The Kia Stonic is Kia's smallest SUV: a five-seat, petrol-only crossover with a 352-litre boot, a 7-year/100,000-mile warranty and three trims. Our guide explains the powertrain, the trim choices and what to check before you order.
The Kia Stonic is a five-seat crossover built around a supermini footprint with a raised body and a little extra ground clearance. At 4.17 metres long, it's aimed at drivers who want the look and the driving position of an SUV without the bulk.
It suits commuters, downsizers and small families who mostly carry two people and occasionally four. Reviewers consistently describe it as sensible, easy to drive and generously equipped, rather than thrilling, and they're honest about tight rear seats.
The choice is simple: one body style, one petrol engine in manual or automatic form, and three trims called Pure, GT-Line and GT-Line S.

Manufacturer data for the versions we currently offer. Last updated 5 October 2026.
The Stonic is a compact, petrol-powered SUV sitting below Kia's larger crossovers. Five seats, five doors, a 352-litre boot with the rear seats up and a 7-year / 100,000-mile manufacturer warranty are the headline points.
The current Stonic is the second-generation car, on sale in this form since 2025. Road testers tend to praise the tidy handling, the amount of standard kit and the long warranty, and criticise the amount of hard plastic inside and the rear legroom compared with a few roomier rivals.
Fold the rear seats and boot space rises to 1,155 litres, which covers flat-pack runs and bikes with the wheels off. The turning circle is 10.4 metres, so multi-storey car parks and tight residential streets are no drama.
Because every Stonic arrives with the equipment most drivers actually use, and leasing keeps you inside the 7-year / 100,000-mile warranty for the whole contract. Servicing falls every 12 months or 10,000 miles, which is easy to budget for.
Built-in navigation, a digital instrument cluster, Apple CarPlay and Android Auto, air conditioning and roof rails are standard across the range. So is the safety kit: autonomous emergency braking, lane-keep assist, traffic sign recognition, a rear-view camera, rear parking sensors and automatic headlights.
Insurance groups run from 10 to 13, and official WLTP economy is 48.7 to 51.3 mpg depending on the version, with CO2 from 125 g/km. Bear in mind the spare is a tyre repair kit, not a wheel.
There's only one: a 1-litre turbo petrol driving the front wheels. Nothing to plug in, nothing to charge, and a choice of manual or automatic gearbox depending on the version you pick.
This three-cylinder engine produces 98 to 113 bhp with 172 to 200 Nm of torque, and comes with a 6 or 7-speed gearbox. Expect 0-62 mph in 10.7 to 12.1 seconds and a top speed of 111 to 113 mph, which is plenty for town work and motorway cruising.
Front-wheel drive across the range, a 45-litre fuel tank and braked towing of 900 kg. If you spend most of your time in traffic, look at the automatic first: it's often cheaper to lease than the manual on the same version.

Three trims, and the honest answer is that Pure already covers the essentials, so the decision is about comfort and styling rather than whether the car is properly equipped.
Pure comes with 16-inch alloy wheels, a 12.3-inch touchscreen navigation system, Apple CarPlay and Android Auto, a two-spoke artificial leather steering wheel and a reversing camera system. Cloth upholstery, front parking sensors and front fog lights are included too.
The Pure is currently available from £256.40 a month.
GT-Line adds 17-inch GT alloy wheels, LED headlights, a three-spoke GT-Line artificial leather steering wheel, privacy glass and customisable ambient lighting. You also get artificial leather upholstery, blind-spot monitoring, power-folding door mirrors and rain-sensing wipers.
The GT-Line is currently available from £311.41 a month. Against the Pure, that is currently £55.01/mo more expensive.
GT-Line S adds a tilting and sliding sunroof, a heated steering wheel, smart cruise control with stop and go, and a 12.3-inch driver display screen. Heated front seats, wireless phone charging, active lane-change assist, an auto-dimming rear-view mirror and an electric parking brake come with it.
The GT-Line S is currently available from £343.96 a month. Against the GT-Line, that is currently £32.54/mo more expensive.
One practical note from arranging these contracts: if two people share the car, the adaptive cruise and heated seats on GT-Line S tend to matter more than the wheels. Our guide to choosing your spec, term and mileage is worth five minutes before you order.
