Best Long Range Electric SUVs in the UK

The longest-range electric SUV on sale in the UK in 2026 is the BMW iX3 xDrive50, with approximately 500 miles WLTP, although the Volvo EX60 P12 (503 miles WLTP) and the Hyundai Ioniq 9 (385 miles WLTP, 350 kW charging) are the practical frontrunners for most buyers in the large SUV category.

SUVs face a natural range disadvantage against saloons and hatchbacks: their taller, wider body creates more aerodynamic drag, and the extra weight demands more energy. A long-range electric SUV therefore requires a larger battery than a similarly-ranged saloon to compensate, which pushes prices up. The cars in this guide represent the best of the current market, where improving battery energy density is narrowing the gap.

At a sustained 70 mph on a UK motorway, take 20 to 30 per cent off the WLTP figure

This applies more to SUVs than saloons, because the higher drag coefficient means they shed range more steeply as speed climbs. A 400-mile WLTP electric SUV typically delivers around 280 to 310 miles at 70 mph in mild conditions.

1. BMW iX3 xDrive50: outright range leader

The BMW iX3’s 108 kWh battery and 800-volt architecture make it the first mainstream electric SUV in the UK to clear 500 miles on the official test. At around £58,000, it is also the most affordable car in the 500-mile WLTP bracket. The 800-volt system supports up to 400 kW charging, meaning a 10 to 80 per cent charge can take under 25 minutes at compatible chargers. Real-world motorway range of approximately 375 to 400 miles is exceptional.

Best for: Buyers who want the longest possible SUV range and value the BMW driver experience.

2. Hyundai Ioniq 9: best value in the large SUV class

The Ioniq 9 enters the UK market at around £65,000 with 385 miles WLTP and a 350 kW peak charging rate, the highest of any SUV on this list. Its E-GMP platform is the same 800-volt architecture that underpins the Ioniq 6 and Ioniq 5, which have proven reliability records and strong real-world efficiency. With seven-seat capacity and a practical interior, the Ioniq 9 is the most family-focused option in the upper-large category.

Best for: Families who need seven seats and want strong range and very fast charging.

3. Kia EV9 Dual Motor: the proven towing choice

The Kia EV9’s 110.3 kWh battery delivers 385 miles WLTP and 2,500 kg towing capacity, making it one of the most capable combination of family, range and tow car available. At around £65,000, it sits alongside the Ioniq 9 in price. The dual-motor version provides strong all-weather traction. Real-world range at 70 mph is approximately 285 to 315 miles. When towing a typical caravan, expect around 130 to 160 miles between charges.

Best for: Buyers who need both long range and a genuine 2,500 kg towing capability.

4. Polestar 3 Long Range: best driving dynamics

The Polestar 3’s 111 kWh battery and 400-mile WLTP rating are backed by a chassis that prioritises handling as well as efficiency. Polestar’s Scandinavian ethos and Volvo underpinnings mean high material quality and a calm driving character, with genuine sportiness available from the 510 hp dual-motor system. Real-world motorway range of approximately 295 to 330 miles.

Best for: Drivers who want SUV practicality but also value how the car drives.

5. Hyundai Ioniq 5 Long Range: best value in the mid-size category

At around £44,495, the Ioniq 5 Long Range offers 354 miles WLTP and 230 kW peak charging at a price significantly below the large-SUV competition. It is smaller than the EV9 or Ioniq 9, but fits most family needs with its spacious interior and flat floor. The E-GMP 800-volt platform delivers fast charging and proven durability. Real-world motorway range of approximately 260 to 285 miles.

Best for: Budget-conscious buyers who want proven tech and solid range without the premium price of larger SUVs.

What are the trade-offs with long-range electric SUVs?

Weight. Most large-battery SUVs weigh 2,200 to 2,500 kg. This affects handling, tyre wear and energy consumption when accelerating. A 2,400 kg SUV requires notably more energy to reach 70 mph than a 1,900 kg saloon.

Charging time. A 110 kWh battery takes longer to charge than a 79 kWh one, even at the same charging rate. A 10 to 80 per cent charge at 200 kW takes around 25 to 30 minutes for a 100 kWh battery; the same operation on a 79 kWh battery at the same rate takes around 20 to 22 minutes.

Price. Long-range electric SUVs cluster around £55,000 to £80,000. There is no equivalent of the sub-£35,000 long-range hatchback in the large SUV category.

The common mistake: buying for WLTP, not for motorway use

An SUV rated at 400 miles WLTP will deliver around 280 to 310 miles at 70 mph in mild conditions. In winter with the heater running, that can drop to 230 to 270 miles. If you need to cover 250 miles on a cold January motorway run, a 400-mile WLTP SUV gives you a tighter margin than you might expect from the headline. Verify the motorway range specifically if that scenario applies to your use.
