The Citroën ë-C4 X is not just cheaper - it also offers 70 litres more boot space. On EVcarsguide's combined category scores, the Renault Megane comes out ahead overall.

The Citroën ë-C4 X is £3,280 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 Citroën ë-C4 X comes out roughly £3,280 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 185 miles for the Citroën ë-C4 X 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 70 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 24-25 minutes.

The Renault Megane is the easier car for tight UK car parks: it is 32 mm narrower than the Citroën ë-C4 X. In a standard 2,400 mm bay that leaves about 632 mm of total clearance for the Renault Megane and about 600 mm of total clearance for the Citroën ë-C4 X. 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 84% battery health for the Citroën ë-C4 X and 90% for the Renault Megane. That gives the Renault Megane a modest edge in retained real-world range. The Renault Megane's LFP-type pack tolerates daily 100% charging, while the Citroën ë-C4 X's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
