Despite the EV6 GT's compact exterior dimensions, a 2,900mm wheelbase and flat floor result in cabin space similar to that of many mid-size SUVs, providing exceptional long-distance touring capabilities. The interior benefits from applying Kia's dedicated electric vehicle architecture, E-GMP. The EV6 GT offers intelligent and flexible interior packaging and an abundance of cabin storage areas, including 480 litres of boot space with second-row seats in place. If the second row is folded down, the stowage capacity increases to 1,260 litres. The car also features a front boot, which provides an additional 20 litres of storage – ideal for storing the car's charging cable.
The EV6 GT's unique suspension ensures the car's ride remains flat in all situations, mitigating roll when cornering or changing lanes at high speed. It also limits squatting during rapid acceleration and diving under braking. The ride retains a high degree of fluidity and compliance, whichever drive mode is selected, so it remains an enjoyable place for all occupants, even over long distances.
