Kia EV6
Vauxhall Grandland
The Kia EV6 costs £3,540 more than the Vauxhall Grandland. For that premium it adds 79 kW faster peak rapid charging. The Vauxhall Grandland is not just cheaper - it also offers 60 litres more boot space. On EVcarsguide's combined category scores, the Kia EV6 comes out ahead overall.
The Vauxhall Grandland is £3,540 cheaper to buy. The Kia EV6 is cheaper to charge, roughly £160 a year versus £192 for the Vauxhall Grandland, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Vauxhall Grandland comes out roughly £3,380 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
EVcarsguide estimates a real-world motorway range of about 273 miles for the Kia EV6 and 220 miles for the Vauxhall Grandland - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Kia EV6 goes roughly 53 miles further between charging stops. A rapid charge to 80% takes around 18 minutes in the Kia EV6 and 30 in the Vauxhall Grandland, so the Kia EV6 loses less time at each stop. That makes the Kia EV6 the stronger long-distance car.
The Kia EV6 is the easier car for tight UK car parks: it is 228 mm narrower than the Vauxhall Grandland. In a standard 2,400 mm bay that leaves about 520 mm of total clearance for the Kia EV6 and about 292 mm of total clearance for the Vauxhall Grandland. The Vauxhall Grandland also turns in a 0.7 m tighter circle, which helps with U-turns and multi-storey ramps.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 89% battery health for the Kia EV6 and 84% for the Vauxhall Grandland. That gives the Kia EV6 a modest edge in retained real-world range. Both use NMC-type cells, so for daily use keep the charge limit near 80% to slow degradation. The Vauxhall Grandland has the longer battery warranty at 8 years, versus 7 for the Kia EV6.
