The Kia EV9 is what happens when you take the E-GMP platform, scale it up to accommodate seven seats, and engineer it to charge at 240kW. The result is the most compelling large family EV in the UK market: a genuine seven-seater with 280 miles of real-world range, faster charging than most smaller EVs, and a 7-year warranty. It is, however, a £63,000 car.
Running costs: Kia EV9
3.0 miles per kWh reflects the size and weight penalty — the EV9 is a large, heavy vehicle. Home charging at 28p/kWh costs approximately 9.3p per mile. The Land Rover Discovery it competes against runs on about 30 MPG diesel (diesel at 151.9p/litre = 23p per mile). The annual saving at 15,000 miles versus a comparable large SUV exceeds £2,000. Running cost economics are genuinely compelling at high mileages — it's the purchase price that requires justification.
