Kia EV6 GT Review 2025: Price, specs & boot space

The EV6 range as a whole offers a stylish, if not particularly cheap route into the world of electric cars. The EV6 GT is more of a niche choice - while its performance is very impressive, less expensive versions of the EV6 will be more than fast enough for most.

This page is dedicated to the EV6 GT, of which there's only one version. If you want a broader view of the whole range, check out our main Kia EV6 review.

The most similar is the Hyundai Ioniq 5 N. Kia's parent company is Hyundai Motor Group, and it uses the same platform for both the Ioniq 5 and the EV6. As such, the Ioniq 5 N shares many components with the Kia, although it's more powerful than the EV6 GT, producing 650PS. It's also targeted more at keen drivers, with various bits of tech the Kia doesn't get, including simulated gears and fake engine noise, and has somewhat less subtle styling than its cousin. 

Away from Hyundai Motor Group, the Ford Mustang Mach E GT is probably the EV6 GT's most obvious rival. It's quite a bit more expensive to buy new outright, at £75,690, but it's been around slightly longer, giving used Mach E GTs more of a chance to depreciate. The BMW i4 is a tempting alternative, but it's not quite as practical, and even its range-topping M5 form isn't quite as fast as the Kia. 

The standard EV6 already does quite well in this regard, and the GT takes things up a notch with some lovely textures and materials, particularly the coating for the passenger side of the dashboard. The wobbly armrest is - sadly - still very much present, but it's the only real complaint we have about the cabin. 

It's hard to say how the interior will wear tens of thousands of miles of use and abuse, but we'd be hopeful that the average EV6 GT's cabin will remain feeling fresh for years to come. 

As seen in other EV6, and many other modern cars, the GT combines two screens to form what looks like a single, massive curved display behind the steering wheel. The one on the left replaces a traditional instrument binnacle, while the one on the right is on infotainment duties. There's effectively a third 'screen' you won't see unless you're behind the wheel - a snazzy head-up display (HUD).

The infotainment's colour scheme is quite subdued, but the quality of the graphics is just fine, and the menu systems are easy to navigate. Thankfully, you don't have to use this screen to adjust the climate controls - there's a dedicated panel with physical temperature knobs for the two climate control zones further down the centre console. These days, that's far from a given. 

The EV6 GT's high standard specification means that wireless Apple CarPlay and Android Auto connectivity come as standard. While the factory-fitted navigation system is fine, we tended to shirk it in favour of Google Maps via the Android Auto connection. 

There's a decent complement of USB sockets, with three in the front (two type-C, one of the old style) and two type-Cs in the rear. There are also two 12-volt cigarette lighter-style sockets - one in the front and one in the boot.

The sound system is exceptional, with the GT getting a 14-speaker Meridian surround setup. 

In terms of exterior dimensions, the Kia EV6 GT is the same as the regular car. That means it measures 4695mm in length, 1890mm in width and 1550mm in height.

The Kia EV6 GT's 2900mm wheelbase and flat floor means it feels spacious inside, while there's 480 litres of luggage space in the boot. This increases to 1260 litres with the rear seats dropped, while a front boot provides an extra 20 litres of storage (ideal for stowing away a charging cable).

All of these numbers are the same as any other EV6, so you're not missing out on any practicality by opting for the GT. 

This is an easy one - the EV6 GT only has one powertrain option, which combines a 77.4kWh battery pack with two electric motors. There's one for the front axle, and one for the rear, making the EV6 GT all-wheel drive. 

The EV6 GT's performance comes at quite a cost in terms of range, with an official figure of 263 miles representing a hefty drop from the 339 miles quoted for other all-wheel drive versions of the Kia EV6. What's more, as with all EVs, that number comes from lab testing and will be nigh-on impossible to replicate yourself.

In real-world conditions, you'll be doing well to manage much over 200 miles, especially if you enjoy deploying all of the GT's power quite frequently, and/or are driving in cold weather. 

Insulation from the outside world is especially important for EVs. With no engine to drown things out, excess wind or road noise has nowhere to hide. Happily, the EV6 GT scores well on this front. The relatively wide tyres do generate a decent amount of sound, but what makes it into the cabin certainly isn't excessive. And although the suspension is firm, we didn't notice any vibration or rattling of trim. 

Meanwhile, the spaciousness of the cabin and the quality of the materials means the EV6 GT is a pleasant space in which to spend longer journeys.

The EV6 GT itself hasn't been assessed by Euro NCAP, but the EV6 Long Range AWD tested by the organisation in 2022 is representative of how the GT will perform in a crash. That's good news, as that vehicle came away with the full five-star rating. It was scored at 90% for adult occupants and 86% for child occupants, although it isn't as effective at protecting vulnerable road users, with a score of 64 per cent. 

Being the range-topping model, the EV6 GT isn't left wanting in terms of standard-fit safety technology. It gets (deep breath): driver attention warning, forward collision avoidance, Highway driving assist 2 (best thought of as very clever cruise control), blind-spot avoidance with rear-cross traffic assist, lane keep assistant, lane follow assist, multi-collision brake assist and parking collision avoidance assist.

We haven't heard of any major reliability issues for the EV6 range for a whole, and there's no reason to believe that the GT will be any less reliable than other cars in the range. As a brand, Kia has long performed strongly in the HonestJohn.co.uk annual satisfaction index. 

With no engines or gearboxes to worry about, electric cars don't have as many moving parts as combustion-powered vehicles, and that means there isn't as much to go wrong. And if that wasn't enough to put your mind at rest, all Kia models come with an impressive seven-year warranty. 

If you reach 100,000 miles within that timeframe the warranty will expire early, but since that represents an average of over 14,000 miles a year, most drivers won't need to worry about it. 

As with any vehicle, the cost of car insurance on an EV6 GT will vary significantly depending on myriad factors including where the car is kept, your age, driving history and more. However, we can say with some confidence that the GT will cost you a reasonable amount more than other EV6s, as it sits in group 45, some nine places higher than the entry-level EV6 Air.

It's also worth bearing in mind that EVs are generally slightly more expensive to insure than combustion-powered vehicles of similar value. Make sure you get several quotes to ensure you're happy with premium prices before agreeing to buy. 

This is something set to change not just for the EV6 GT, but every electric car. From 1 April 2025, the EV6 GT will cost £190 to tax, having previously been exempt from any vehicle excise duty (VED). 

The GT is also liable for the government's expensive car surcharge, which means forking out £490 annually on top of that £190 between the second and sixth years of the car's existence. We can't single out the GT for this, though, as all versions of the Kia EV6 are beyond the £40,000 threshold for the additional charge.

Buying a Kia EV6 GT isn't going to be a complicated experience. It's only available in one trim level, and you won't need to spend hours agonising over the configurator or looking at wildly different specs on used examples, as the only options to pick from are the colours, of which there are five. Runway Red is the sole free hue, while the three 'Premium' colours are £675, and Steel Matt Grey will add a whipping £1,500 to the price tag. The only other things to pick in the configuration are accessories, rather than optional extras. 

Making the EV6 GT's high price easier to swallow, the standard spec is excellent. Along with the broad offering of safety technology mentioned earlier, the car comes with 21-inch alloy wheels, two 12.3-inch screens (one for the infotainment and the other forming the instrument cluster), an energy-saving heat pump, a 360-degree parking camera, an excellent 14-speaker Meridian sound system and much more besides.
