Cupra Tavascan vs Kia EV6

The Cupra Tavascan costs £1,705 more than the Kia EV6. For that premium it adds 50 litres more boot space, 42 kW more power and a 0.9s quicker 0-62mph time. The Kia EV6 is not just cheaper - it also offers 123 kW faster peak rapid charging. On EVcarsguide's combined category scores, the Kia EV6 comes out ahead overall.

The Kia EV6 is £1,705 cheaper to buy. Running costs are almost identical - about £152 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Kia EV6 comes out roughly £1,665 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 294 miles for the Cupra Tavascan and 301 miles for the Kia EV6 - 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 28 minutes in the Cupra Tavascan and 18 in the Kia EV6, so the Kia EV6 loses less time at each stop.

The two are within 29 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 539 mm of total clearance for the Cupra Tavascan and about 510 mm of total clearance for the Kia EV6. The Cupra Tavascan 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 84% battery health for the Cupra Tavascan and 89% for the Kia EV6. 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.
