Longest Range Electric Cars in the UK for 2026

The electric car with the longest range on sale in the UK in 2026 is the Mercedes EQS 450+, at 542 miles WLTP. In real-world mixed driving, that translates to approximately 400 to 430 miles per charge. Below it, a growing cluster of models from BMW, Volvo, Tesla, Audi and Volkswagen now offer 400 miles or more on the official test.

The key takeaway: real-world range is consistently 70 to 80 per cent of WLTP in mixed UK conditions. Apply that multiplier before planning any journey.

The full range leaders in detail

1. Mercedes EQS 450+

The EQS has led the UK range chart since launch. Its 118 kWh battery, ultra-low 0.20 drag coefficient and sophisticated thermal management combine to produce a WLTP figure no other model can currently match. Real-world figures of 400 to 430 miles in mixed driving are supported by owner data. The car itself is a full-size luxury saloon with a price to match: from around £94,000. For company car drivers, the benefit-in-kind tax rate remains favourable for EVs, which softens the personal tax exposure.

2. Volvo EX60 P12

A notable newcomer at the top of this list, the EX60 P12’s 503-mile WLTP claim is backed by a large battery and Volvo’s well-regarded thermal management. Prices from around £62,000 put it in the premium executive crossover segment. Real-world range of 375 to 405 miles makes it a genuine long-distance choice.

3. BMW iX3 xDrive50

The BMW iX3’s 108 kWh battery and 800-volt architecture (supporting up to 400 kW charging) deliver both exceptional range and very fast charging. At around £58,000, it is the most affordable of the 500-mile WLTP trio and arguably the most practical family SUV of the three.

4. Tesla Model 3 Long Range RWD

The most important car in this list for most buyers: at £45,990, the Model 3 Long Range is the most affordable 400-plus mile WLTP car in the UK, and it sits in the core family saloon segment rather than the executive market. Its Cd of 0.23, optimised drivetrain and Tesla’s Supercharger network make it the best all-round long-range package for mainstream buyers. Real-world range of 350 to 380 miles in mixed conditions makes it one of the few cars that comfortably covers 300 miles of motorway on a single charge.

5. Audi A6 e-tron Performance

Audi’s elegant E-tron GT successor in the mainstream segment. The 100 kWh battery and 800-volt charging platform (up to 270 kW) combine class-leading interior quality with genuine long range. From around £63,000.

Key budget option: MG4 Extended Range

For buyers prioritising range per pound, the MG4 Extended Range at £28,495 and 323 miles WLTP is a standout. Real-world range of around 240 to 265 miles puts it ahead of many cars that cost £15,000 to £20,000 more. It does not have a heat pump, which widens the winter range gap, but for mixed-use everyday driving it represents exceptional value.

What does real-world range mean in practice?

The WLTP test averages 29 mph with no climate control load and runs at 23 degrees Celsius. UK driving is faster, colder for much of the year and involves heaters. For journey planning, use these multipliers:

• Mixed UK driving: multiply WLTP by 0.75
• 70 mph motorway: multiply by 0.70 to 0.75
• Cold winter with heater (no heat pump): multiply by 0.60 to 0.65
• Cold winter with heat pump: multiply by 0.65 to 0.72

Which long-range car represents best value?

For most UK buyers who want genuine long range without a luxury premium, the Tesla Model 3 Long Range remains the benchmark. At under £46,000, it offers 466 miles WLTP with a proven Supercharger network, strong real-world efficiency and a low 2 per cent BiK rate for company car drivers (a saving of thousands per year versus a comparable petrol car).

The Renault Scenic E-Tech at £38,495 with 379 miles WLTP is the value pick for families wanting a larger body style without crossing the £40,000 threshold. For buyers who can stretch higher, the MG4 Extended Range at £28,495 is unmatched for range-per-pound in the mainstream market.

Company car buyers: what is the BiK picture?

All zero-emission vehicles registered from 6 April 2025 attract a 3 per cent BiK rate, rising to 4 per cent in 2026/27. For higher-rate taxpayers choosing a £50,000 EV, the annual BiK tax liability is around £600 to £800 per year, versus £4,000 to £7,000 for a comparable petrol executive car. The financial case for company car EV adoption in the long-range bracket remains strong.

Common mistake: buying maximum WLTP without checking real-world data

The range table above shows WLTP figures, but the real-world column is what you should plan from. A car rated at 400 miles WLTP does not do 400 miles on a motorway. It does roughly 280 to 310 miles at 70 mph in mild conditions. Budget for that, not the headline.
