MG4 EV vs Leapmotor B10 UK 2026: Same £29,995 price — very different deals

This is a comparison of two very different corporate bets. The MG4 is made by MG Motor UK, a wholly owned division of SAIC Motor — China's seventh-largest automaker, a Fortune 500 state-owned enterprise with H1 2025 revenue of ¥299.59 billion. SAIC is not going anywhere. MG has been selling cars in the UK for decades, has a deep dealer network, and is so embedded in UK motoring that most buyers do not even think of it as a Chinese brand. Survival risk is as low as any marque on sale. The Leapmotor B10 is a different proposition: Leapmotor International is a joint venture in which Stellantis holds a 51% controlling stake. That is the same Stellantis behind Peugeot, Vauxhall, Citroën, and Fiat — which provides genuine structural backstop. Leapmotor itself turned its first annual profit in 2025 (CN¥540 million) on 596,555 deliveries. But Stellantis posted a €22.3 billion loss in 2025 (with €46 billion liquidity), and Leapmotor is a younger company. Both are credible purchases; MG's backing is simply deeper.

Both cars retail at £29,995 — the MG4 EV Gen 1 Premium Long Range at that price without any special grant, and the Leapmotor B10 Design at £29,995 with the LEAP-GRANT (a £1,500 manufacturer subsidy; the list price is £31,495). Confirm the LEAP-GRANT's current availability with your dealer — terms can change. On paper the prices are identical. The warranty is where the divergence is stark: MG offers 7 years and 80,000 miles on the vehicle (plus 8 years / 100,000 miles on the battery). Leapmotor offers 4 years / 60,000 miles on the vehicle — shorter than virtually every rival in this price bracket. The battery warranty matches at 8 years / 100,000 miles. For a buyer planning to keep the car beyond four years, the MG's warranty is a meaningful advantage. For a salary-sacrifice buyer on a three-year term, it matters less.

The MG4 EV Gen 1 offers 280 miles of WLTP range from a 62 kWh LFP battery, accepting DC power at up to 150 kW — 10 to 80 per cent in approximately 25 minutes. The Leapmotor B10 offers 270 miles from a 67.1 kWh (65.0 kWh usable) LFP battery, but charges at up to 168 kW — 30 to 80 per cent in approximately 20 minutes. The B10's charging speed is genuinely impressive for the price: faster than most cars in its class and substantially faster than the MG4. In daily use, ten fewer WLTP miles is not a meaningful disadvantage. The B10 also includes a heat pump and V2L (3.3 kW) — the MG4 Gen 1 at this price point has neither heat pump (it's on higher trims) nor V2L. No heat pump means the MG4's real-world winter range will be noticeably shorter than the B10's under comparable conditions.

Both cars have achieved five stars from Euro NCAP, but the tests are three years apart. The MG4 EV Gen 1 was tested in 2022 under older (less demanding) protocols; the Leapmotor B10 was tested in November 2025 under the significantly stricter current framework and scored 93% adult occupant, 93% child, 84% pedestrian, 85% safety assist. The B10's 2025 result is more meaningful for a buyer today. On practicality, the B10 wins clearly: 430-litre boot versus the MG4 Gen 1's 363 litres, a 25-litre frunk, a 360-degree camera system, and a 14.6-inch 2.5K touchscreen. Both cars include Apple CarPlay and Android Auto. The MG4's trump card in tech is the established UK infotainment ecosystem — buyers have had several years to form views on its stability. The B10 is newer and there is less long-term owner data on infotainment quality in UK conditions. UK Driver Power is the shadow over MG as a brand: MG finished dead last in both 2023 and 2024 surveys. The product is not the problem — Chinese owner data shows dealer service and complaint handling are the root cause. Worth asking your local MG dealer how that is improving.

At an identical £29,995 entry price, this is a genuinely close contest that comes down to priorities. Choose the MG4 EV Gen 1 if you want the longer warranty (7 years versus 4), a more established brand with a deeper UK dealer footprint, and you primarily use the car for longer trips where those extra 10 WLTP miles add up. The MG4 is the lower-risk default for buyers who want to minimise uncertainty. Choose the Leapmotor B10 if faster charging matters (168 kW versus 150 kW is a real-world advantage on longer journeys), you want V2L for camping or power outages, you benefit from the heat pump in winter, and you are comfortable with the shorter vehicle warranty — particularly if you are buying on a salary-sacrifice scheme where three years is the typical term. The B10 also wins on interior space and equipment. Both are credible purchases. Neither is a punt.
