Frequently asked questions
Is the Tesla Model S worth the extra £41,455 over the Kia EV6?
The Tesla Model S costs £41,455 more than the Kia EV6. For that premium it adds 77 miles more WLTP range, 255 litres more boot space and 177 kW more power. On EVcarsguide's combined category scores, the Kia EV6 comes out ahead overall.
Which is cheaper to own over 5 years, the Kia EV6 or the Tesla Model S?
The Kia EV6 is £41,455 cheaper to buy. The Kia EV6 is cheaper to charge, roughly £160 a year versus £192 for the Tesla Model S, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Kia EV6 comes out roughly £41,615 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Kia EV6 and Tesla Model S like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 273 miles for the Kia EV6 and 280 miles for the Tesla Model S - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. A rapid charge to 80% takes around 18 minutes in the Kia EV6 and 30 in the Tesla Model S, so the Kia EV6 loses less time at each stop.
Which is easier to park and drive in town, the Kia EV6 or the Tesla Model S?
The Kia EV6 is the easier car for tight UK car parks: it is 84 mm narrower than the Tesla Model S. In a standard 2,400 mm bay that leaves about 520 mm of total clearance for the Kia EV6 and about 436 mm of total clearance for the Tesla Model S.
Which battery will hold up better as a used buy, the Kia EV6 or the Tesla Model S?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 89% battery health for the Kia EV6 and 84% for the Tesla Model S. 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 Tesla Model S has the longer battery warranty at 8 years, versus 7 for the Kia EV6.
