Kia EV4 vs Renault Megane

The Kia EV4 costs £2,750 more than the Renault Megane. On the headline specs that premium buys little measurable advantage - the two are closely matched on range, charging and space. The Renault Megane is not just cheaper - it also offers 35 miles more WLTP range and 38 kW faster peak rapid charging. On EVcarsguide's combined category scores, the Renault Megane comes out ahead overall.

The Renault Megane is £2,750 cheaper to buy. Running costs are almost identical - about £144 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Renault Megane comes out roughly £2,710 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 226 miles for the Kia EV4 and 255 miles for the Renault Megane - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Renault Megane goes roughly 29 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 24-31 minutes.

The Renault Megane is the easier car for tight UK car parks: it is 92 mm narrower than the Kia EV4. In a standard 2,400 mm bay that leaves about 632 mm of total clearance for the Renault Megane and about 540 mm of total clearance for the Kia EV4. The Renault Megane also turns in a 0.5 m tighter circle, which helps with U-turns and multi-storey ramps.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 89% battery health for the Kia EV4 and 90% for the Renault Megane. That is close enough that capacity loss should not decide between them. The Renault Megane's LFP-type pack tolerates daily 100% charging, while the Kia EV4's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
