2023 Kia EV6 GT Review: Quickest Kia Tested

The new Kia EV6 GT is set to find itself in some very distinguished company. The turned-up version of Kia’s mid-size electric crossover is a zero-emission muscle car with horsepower output that beats some much pricier offerings. This family hauler cranks out 577 horsepower across its two motors, which should deliver a 60-mph time in the low threes. And while most electric cars have speed limiters set low for reasons of both range and sensibility, the Kia EV6 GT is capable of 161 mph. Also, it has a drift mode.

Riding on Hyundai-Kia’s highly advanced E-GMP platform, the GT promises to be impressively svelte by the pudgy standards of its segment, tipping the scales at a claimed 4780 pounds. Moreover, this platform can deliver ultraquick DC fast-charging rates of up to 240 kW—sufficient to replenish the relatively small 77.4-kWh battery pack from 10 to 80 percent in 18 minutes at a 350-kW DC fast-charge station, according to Kia.

Next to the all-wheel-drive EV6 GT-Line that sits just below the EV6 GT in the hierarchy, visual distinction is limited; the GT definitely doesn’t shout about its extra performance. The front and rear bumpers have been subtly changed, 21-inch wheels are standard (necessary to fit around larger brake discs), and a liftgate spoiler is fitted. Inside, the GT gets semi-bucket sports seats trimmed in microfiber, some new performance touchscreen displays, and, on the steering wheel, a GT button that accesses the new Dynamic mode, which joins the regular Eco, Normal, and Sport settings.

Kia EV6 GT Performance and Range

Mechanical changes are more significant. The GT is powered by significantly brawnier motors than the current all-wheel-drive EV6, with the one at the front now having a maximum output of 215 horsepower and the rear unit making up to 362 horsepower. The rear axle also features a torque-biasing differential that varies the amount of thrust sent to each wheel, and the rear motor adds another bit of leading-edge EV tech, a two-stage inverter that uses silicon-carbide semiconductors. This improves efficiency by up to 3 percent while also reducing heat generated when the motor is working harder. As in other high-performance EVs, output is restricted in lesser drive modes: Eco limits the system peak to 288 horsepower, while Normal and Sport lift that to 460. Only GT mode unleashes the full 577 ponies.

The result is a seriously quick car. As in the existing EV6, the GT has a relatively gentle accelerator response at the top of the pedal’s travel. (This is especially obvious in the likely little-used Eco mode, which seems to add an inch of deadness to the top of the accelerator.) But pushing the pedal harder quickly summons forceful thrust, and a standing launch in GT mode creates g-forces that relocate internal organs as the rear tires battle to find traction.

This was on the dry asphalt of a Swedish test track and despite Kia’s fitment of performance Michelin Pilot Sport 4S tires rather than low-rolling-resistance rubber. In Europe, Kia claims a 0-to-62-mph time of 3.5 seconds, but we suspect that the result for our benchmark 60 mph will be even better. (Our 60-mph time for the 320-hp all-wheel-drive version was 4.5 seconds.)

Pressing the GT button on the steering wheel also unlocks the further option of the drift mode. This, you will be entirely unsurprised to hear, is huge fun—even if it’s hard to imagine too many EV6 buyers making even occasional use of it. Kia gave us the chance to experience the system on a skidpad, where it allowed the GT to be easily persuaded into impressive angles of power oversteer, with invisible intervention from the smart rear differential and assistance from the front motor helping to maintain them as speed rises. If nothing else, the ability to smoke tires is an indication of the potency of the most powerful car Kia has ever produced.

But it is at speeds more appropriate for the real world that the active diff impressed more. The ability to send more torque to the outside rear wheel not only helps the car turn in, but also gives a sense of rear-led handling when GT mode is selected. That makes the GT feel exciting well short of any loss of grip. As in lesser EV6s, the steering is precise and direct, although little low-level feedback gets past the weighty assistance.

Ride quality was very impressive. The GT gets adaptive dampers as standard, and even in their firmer mode, they handle bumps and dips with assured compliance. Although the GT has stiffer springs, there’s still discernible roll under cornering. Cruising refinement is excellent. We didn’t confirm the claimed 161-mph top speed on Sweden’s well-policed highways (it’s a nation where traveling 5 km/h over the posted limit feels daring), but at highway velocities, the GT’s cabin was snug and well insulated.

Interior and Everyday Use

The Kia EV6 GT’s softness actually suits it well and is a result of the deliberately distinct character given to the closely related Kia and Hyundai models. It seems certain that the upcoming Hyundai Ionic 5 N, which will use the same powertrain, will be firmer and more aggressive.

Driving aside, the GT is pretty much indistinguishable from the existing EV6. The cabin is spacious and solidly constructed, although the dark, durable materials separate the GT from the more luxurious alternatives its performance puts it into contention with. Similarly, the 12-inch central touchscreen’s user interface is more effective than impressive, with the navigation system feeling clunky and a little old-fashioned. Fortunately, drivers can use Apple CarPlay and Android Auto instead.

Range is another area where the Kia EV6 GT is off the pace of similarly potent alternatives—with the proviso that we don’t have official EPA numbers yet. The European WLTP figure of 263 miles represents a 65-mile reduction over the rangiest rear-wheel-drive 77.4-kWh version. If that reduction were to carry through to EPA testing, the GT would end up with an official range of under 250 miles.

Kia EV6 GT Price and Verdict

Compare premium picks in our Genesis GV80 review and family haulers in our Mercedes V-Class review; official specs at Kia. The Kia EV6 GT suits drivers wanting pace with practicality.

Pricing is also to be confirmed, although if U.S.-bound EV6 GTs follow the example of Europe, where the car is already on sale, it will be an electric-performance bargain. For perspective, on the other side of the Atlantic, the Kia is both quicker than the Porsche Taycan 4S and pretty much 50 percent cheaper. If Kia brings the GT in for under $70,000, it will manage the same trick here.

With a wave of other electric models set to follow in short order, the Kia EV6 GT shows that Kia is pushing its way to the sharp end of the EV revolution.
