Renault Megane vs Vauxhall Frontera

The Renault Megane costs £8,000 more than the Vauxhall Frontera. For that premium it adds 120 miles more WLTP range, 65 kW faster peak rapid charging and 77 kW more power. On EVcarsguide's combined category scores, the Renault Megane comes out ahead overall.

The Vauxhall Frontera is £8,000 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 Vauxhall Frontera comes out roughly £7,960 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 255 miles for the Renault Megane and 155 miles for the Vauxhall Frontera - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Renault Megane goes roughly 100 miles further between charging stops.

The two are within 27 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 632 mm of total clearance for the Renault Megane and about 605 mm of total clearance for the Vauxhall Frontera. 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 90% battery health for the Renault Megane and 90% for the Vauxhall Frontera. 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. Both batteries carry a 8-year manufacturer warranty.
