Mazda 6e vs Renault Megane

The Mazda 6e costs £7,000 more than the Renault Megane. For that premium it adds 42 miles more WLTP range, 30 kW faster peak rapid charging and 30 kW more power. The Renault Megane is not just cheaper - it also offers 104 litres more boot space. On EVcarsguide's combined category scores, the Renault Megane comes out ahead overall.

The Renault Megane is £7,000 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 Renault Megane comes out roughly £7,000 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 290 miles for the Mazda 6e and 255 miles for the Renault Megane - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Mazda 6e goes roughly 35 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 24-24 minutes.

The Renault Megane is the easier car for tight UK car parks: it is 122 mm narrower than the Mazda 6e. In a standard 2,400 mm bay that leaves about 632 mm of total clearance for the Renault Megane and about 510 mm of total clearance for the Mazda 6e. The Renault Megane also turns in a 1.2 m tighter circle, which helps with U-turns and multi-storey ramps.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the Mazda 6e and 90% for the Renault Megane. That is close enough that capacity loss should not decide between them. Both use LFP-type cells, which are happy charged to 100% every day.
