What are the running costs?

The EV6 is a highly efficient EVs, and fuelling costs will be determined by where you charge it. Its impressive Miles Per Pound 5.6 - 11.2 figure reflects this – the lower number is how how much it costs if you top it up at home on your own wallbox. Kia claims a 328-mile range in official WLTP testing, and although we didn’t match that during our winter test (batteries are less efficient in the cold), previous experience with Kias suggests it’s not too difficult to go further in the right conditions.

The 325hp four-wheel-drive version can’t quite match that, with a WLTP combined range of 314 – we only managed about 235 in real world driving – but either way, this is one of the longer-range EVs you can buy today.

It uses an 800-volt electronic architecture (in common with Porsche’s Taycan, but novel enough to be unusual), simply meaning that it can be charged twice as fast as a lot of other EVs currently on the road. If you’re able to plug into a 350kW rapid charger, you’ll see a 10 to 80% top-up done in 18 minutes. Doing the same task at a 50kW charger will take 73 minutes.

In addition to this, the EV6 also has the ability to act as a power bank for external items – such as your home, power tools or even e-powered bikes and scooters – just like the Ioniq 5.

Servicing and warranty

The Korean carmaker is world famous for its long warranty, which runs to an impressive seven years – matching SsangYong and MG for the longest warranty in the business, which guarantees the car for up to 100,000 miles.

Kia offers a three-tier servicing plan for its owners, based on mileage and age – allowing you to pay up-front for your garage visits depending on how you use your car.

Reliability

  • Kia’s reputation is excellent
  • Seven-year warranty one of the longest around
  • All EV6 models feel built to last

All Kias come with a seven-year, 100,000 mile warranty, which is one of (if not the) the most comprehensive and lengthy in the business, sending a clear message that the South Korean company has faith in its own model range. That claim would seem to hold water, as Kia drivers generally report that they’re happy with their vehicles and don’t appear to suffer from poor reliability.The EV6 certainly feels as though it’s been built to last, with hardwearing materials inside and excellent quality, with no squeaks or rattles when driving.
