Peugeot e-308 SW vs Renault Megane

The Renault Megane is £270 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 two land within £230 of each other - effectively the same to own. 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 229 miles for the Peugeot e-308 SW 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 25 miles further between charging stops.

The Renault Megane is the easier car for tight UK car parks: it is 84 mm narrower than the Peugeot e-308 SW. In a standard 2,400 mm bay that leaves about 632 mm of total clearance for the Renault Megane and about 548 mm of total clearance for the Peugeot e-308 SW. The Renault Megane also turns in a 0.7 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 Peugeot e-308 SW 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 Peugeot e-308 SW's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
