MG4 EV vs Renault 5 E-Tech: Price, Range and Running Costs Compared

Company car tax treats both cars the same way in principle: as pure electric cars, both qualify for the 3% Benefit in Kind rate in 2025/26, rising to 4% in 2026/27, regardless of brand or list price. Insurance is harder to compare cleanly. MG has published insurance groups of 27 to 29 for the bigger-battery Long Range trims on the older range, but no group specifically for the Urban Comfort Standard Range this comparison otherwise uses. Renault has published no insurance group for the 5 E-Tech among the sources this comparison uses either, so neither figure should be taken as final; buyers should get a quote for their exact trim before ordering.

All range figures here are WLTP, and neither car should be read against a Chinese CLTC figure. The MG4 EV Urban Comfort Standard Range covers 201 miles WLTP on its 43kWh battery, the smallest and cheapest option in MG's own line-up; buyers wanting more range can step up to the Urban's own bigger-battery trims, or to the separate older range, which runs as high as 338 miles on a much larger pack. The Renault 5 E-Tech's entry evolution trim covers 192 miles WLTP on its 40kWh battery, 9 miles short of the MG4 Urban entry on a similarly sized pack.

DC charging is one figure MG has not published cleanly for the exact trim this comparison uses, and MG's own pages disagree on the band: figures of 70 to 120kW and of up to 140kW both appear across MG's own specification pages for the same Urban range. Neither figure is tied to the entry Comfort Standard Range specifically, so this comparison states both bands rather than picking one. The separate older range charges faster still, at up to 150kW. The Renault 5 E-Tech's entry 40kWh pack charges at up to 80kW DC, with a 15 to 80% top-up taking around 31 minutes; Renault's own larger 52kWh pack, not sold as the entry trim, reaches 100kW. On AC, the MG4 takes an 11kW three-phase supply; no AC charging figure is published for the Renault 5 E-Tech among the sources this comparison uses.

MG backs the 4 EV with a 7-year or 80,000-mile vehicle warranty and an 8-year or 100,000-mile battery warranty with a 70% state-of-health guarantee, both fully transferable to a subsequent owner. Renault's vehicle warranty runs 3 years from first registration, unlimited mileage for the first 24 months and then capped at 100,000 miles in total, a shorter term than MG's 7 years despite the higher mileage cap; Renault separately warranties the traction battery for 8 years or 100,000 miles, which does land on the same number as MG's own battery cover. On safety, the MG4 Urban scored a 5-star Euro NCAP rating in its 2025 test: 87% adult occupant, 85% child occupant, 85% vulnerable road users and 80% safety assist. The Renault 5 E-Tech scored 4 stars in its own 2024 test. A star-rating difference reflects the test's own scoring thresholds and should not be read on its own as a verdict on which car is safer in an actual crash; both cars passed Euro NCAP's full assessment and each result stands on its own test.
