The Mach-E carries 11 kWh more usable battery and travels about 24 km further on it. The EV6 recovers 10 to 80 percent in seventeen minutes against 32, and costs £13,755 less in the UK. Very little else about these two cars is close.
What actually differs
- Ford Mustang Mach-E Extended Range RWD goes 24 km further on the observed real-world figure than the Kia EV6 84 kWh RWD.

Range
475 km observed for the Mach-E against 451 km for the EV6, from 91 kWh against 80. Consumption is 185 Wh/km for the Mach-E against 178 for the EV6. The Ford carries 11 kWh more battery but spends part of it on being the thirstier car: the extra capacity buys 24 km, where at the Kia’s consumption it would have bought about 60.
On the EPA cycle the EV6 is ahead, 319 miles against 320 — within a mile, so call it level. On WLTP the Mach-E leads at 615 km against 583. Two large family cars going roughly the same distance.
Charging: the EV6 halves it
263 kW peak on an 800-volt pack against 150 kW on 400, and seventeen minutes against 32 across the 10-80 percent window. The EV6 has the quickest rapid charge of any car in this database, tied with the Hyundai Ioniq 6 at seventeen minutes; the Mach-E is mid-pack.
Fifteen minutes per stop is the largest time difference in this comparison, and it partly offsets the Mach-E’s range advantage: the EV6 stops sooner but leaves much faster.
Price, and one caveat about it
£45,635 against £59,390 in the UK — £13,755, which is a great deal of money for eleven kilowatt-hours. Note that the Mach-E figure is the European car; Ford sells a different, larger Extended Range pack in North America at a different price, and the credit lines in the table say which market each figure came from.
Recall record
Four battery, electrical or powertrain campaigns for the EV6 on the NHTSA record over four model years; none at all for the Mach-E. Both hold five NHTSA stars.
Which one should you buy
Buy the EV6 for the fastest charging on this site — matched only by the Ioniq 6 — 3.6 kW of vehicle-to-load, and a very large price saving in the UK.
Buy the Mach-E for the bigger battery, the longer WLTP range and a clean battery recall record — and if you are in North America, where the larger pack and different pricing change the arithmetic.
Frequently asked questions
Which charges faster, the EV6 or the Mach-E?
The EV6, by a wide margin: seventeen minutes from 10 to 80 percent against 32. Its 800-volt architecture peaks at 263 kW against the Mach-E’s 150 kW and holds high power for longer.
Which has more real-world range?
The Mach-E, at about 475 km against 451 km. Both consume almost exactly the same energy per kilometre, so the difference is simply the larger battery.
Why is the Mach-E so much more expensive here?
The prices shown are UK list prices for each car as sold in that market. The Mach-E Extended Range is positioned considerably higher in the UK than the EV6 Long Range RWD.
