Electric Car Range: Longest Range EVs in the UK (2026)

The electric car with the longest range on sale in the UK in 2026 is the Mercedes EQS, at up to 542 miles on the official WLTP test. The average new electric car now manages around 300 miles, and the average car in England covers about 7,100 miles a year, or under 20 miles a day. For most drivers, any EV with 250 miles or more is plenty.

Range figures on their own only tell half the story. A 500 mile car with a 120kWh battery also takes far longer to fill at home than a smaller one. So this guide lists the longest range electric cars you can buy today, shows how far they really go, and works out how long each one takes to charge on a home charge point.

We sell charging cables for a living, so the charging side is where we can add something the car magazines leave out.

What is a good range for an electric car?

A good range for most UK drivers is 250 miles or more. That covers a normal week of driving on one charge, with plenty left over.

The numbers back this up. The average car in England covered about 7,100 miles in 2024, according to the Department for Transport's National Travel Survey, as summarised by the RAC Foundation. That is roughly 19 or 20 miles a day, or about 136 miles a week.

Meanwhile, the average range of a new electric car has climbed to around 300 miles in 2026, up from 235 miles in 2024, according to the RAC.

Range matters more if you:

• regularly drive more than 150 miles in a day
• cannot charge at home and rely on public charge points
• tow, carry heavy loads or do a lot of fast motorway miles
• live somewhere with long, cold winters

If none of those apply, a smaller battery is usually the smarter buy. It costs less, weighs less and charges faster at home. If you are still deciding whether to switch, our reasons to make the switch to an EV covers the bigger picture.

Which electric cars have the longest range in 2026?

The Mercedes EQS leads with an official 542 miles, followed by the Volvo EX60 at 503 miles and the new BMW iX3 at 500 miles. The Tesla Model 3 is the best value long range car, with 466 miles from around £45,000.

These are the ten longest range electric cars on sale in the UK, using the WLTP figures and prices published by Auto Express in July 2026. We have added battery size where the maker publishes it, and our own estimate of how long each takes to charge from empty on a 7.4kW home charge point.

Battery sizes for the Tesla Model 3 and Mercedes CLA come from DriveElectric's 2026 list. Charging times are battery size divided by 7.4kW, rounded. Real charging takes roughly 10% longer because of losses in the charger and battery.

Just outside the top ten, the Peugeot E-3008 Long Range (435 miles), Volvo ES90 (435 miles) and Volkswagen ID.7 Pro S (434 miles) all pass 430 miles. We stock cables for the Peugeot 3008 and Volkswagen ID.7.

Which cheaper electric cars have the best range?

Under £30,000, the MG4 goes furthest at 281 miles, followed by the Leapmotor B10 at 270 miles and the Vauxhall Corsa Electric at 266 miles. Every car on this list clears 245 miles, which is more than a week of average driving.

This shortlist comes from Top Gear's December 2025 round up of the longest range electric cars under £30,000.

Smaller batteries have a practical upside at home. The Nissan Micra's 52kWh battery fills from empty in about 7 hours on a 7.4kW charge point, comfortably inside one night.

How far will an electric car really go?

Expect 10% to 30% less than the official WLTP figure in normal UK use. The gap is widest on cold winter motorway trips and smallest in mild weather around town.

WLTP is a lab test. Every car runs the same cycle, so it is useful for comparing one car with another. It does not include winter heating, 70mph motorway runs or a boot full of luggage. DriveElectric puts the typical real world shortfall at 10% to 30%.

Independent tests show the spread. In What Car's real range testing, a Ford Mustang Mach-E rated at 379 miles managed 302 miles in summer and 247 miles in winter. A BMW i4 eDrive40 rated at 365 miles covered 316 miles.

Extreme cold hits harder. In the 2026 El Prix winter test run by Norway's Motor.no, 25 electric cars fell short of their WLTP range by about 37% on average, in temperatures down to minus 31°C, as reported by InsideEVs. The best car lost 29%. UK winters are far milder, so treat that as the worst case.

A simple rule works well. Take the WLTP figure, knock off a quarter for winter motorway driving, and you have a safe planning number. A 400 mile car becomes a 300 mile car in January.

Why do some electric cars go further than others?

Range comes from two things: how big the battery is and how efficiently the car uses it. A big battery in an inefficient car can go no further than a small battery in an efficient one.

Efficiency is measured in miles per kWh. You can estimate it from the table above by dividing the range by the battery size:

• Tesla Model 3: 466 miles from 75kWh, about 6.2 miles per kWh
• Mercedes CLA: 480 miles from 85kWh, about 5.6 miles per kWh
• BMW iX3: 500 miles from 108.7kWh, about 4.6 miles per kWh
• Mercedes EQS: 542 miles from 122kWh, about 4.4 miles per kWh

The low, slippery saloons are the most efficient. Tall SUVs push more air and weigh more, so they need bigger batteries to reach the same distance.

Efficiency also decides your running costs. Every kWh you put in the battery costs the same whatever the car, so the Model 3 goes about 40% further than the EQS on each unit of electricity.

The other factors are the ones you control. Speed matters most, because air resistance rises sharply above 60mph. Cabin heating, cold batteries, roof boxes, towing and under-inflated tyres all cut range too.

How long does a long range electric car take to charge at home?

Divide the battery size in kWh by the charging power in kW. A 75kWh Tesla Model 3 takes about 10 hours from empty on a 7.4kW home charge point, while a 122kWh Mercedes EQS takes about 16.5 hours.

7.4kW is the most a normal UK home can deliver. Houses in the UK have a single phase supply, and a 32A single phase charge point tops out at 7.4kW. Many long range cars can accept 11kW or 22kW on AC, but only on a three phase supply that almost no homes have. Our guide to home charger installation costs explains what a three phase upgrade involves.

Your cable sets the ceiling too. On a home or public charge point without a fixed lead:

• a 32A Type 2 to Type 2 cable delivers the full 7.4kW
• a 16A cable halves that to 3.7kW, doubling the charging time
• a Type 2 to 3 pin granny cable from a household socket runs at roughly a third of the 7.4kW rate

In practice you rarely charge from empty. An average week of about 136 miles uses around 25kWh to 35kWh, depending on the car. A 7.4kW charge point replaces that in four or five hours, one evening a week. Leaving the car plugged in overnight is fine, as our guide to charging overnight explains.

A 3 pin cable can work for long range cars too, as long as your daily mileage is modest. Our guide to charging from a regular 13 amp socket covers how much range you get back per hour, and the safety rules that go with it.

If your charging is slower than these numbers suggest, the cable, the car's onboard charger or its settings are the usual suspects. See why is my electric car charging slowly.

How can you get more range from your electric car?

Drive a little slower, warm the car while it is still plugged in, and keep your tyres at the right pressure. Those three habits make the biggest difference for the least effort.

1. Keep motorway speeds down. Dropping from 75mph to 65mph noticeably cuts energy use, because drag rises steeply with speed.
2. Precondition on the plug. Heating the cabin and battery before you set off uses mains power instead of battery power. Most cars let you schedule it from the app.
3. Use seat and steering wheel heaters. They warm you directly and use far less energy than heating the whole cabin.
4. Check tyre pressures monthly. Soft tyres add rolling resistance on every mile.
5. Turn regenerative braking up. Stronger regen recovers more energy when you slow down, especially in town.
6. Take the roof box off when you are not using it. It adds drag at any speed.
7. Park in a garage in winter if you have one. A warmer battery starts the day with more usable range.

Rain does not affect range in any meaningful way, and charging in the wet is safe. Our guide to charging in the rain explains why.

Does an electric car lose range as it gets older?

Yes, a little. Batteries lose some capacity over the years, so an older car will go slightly less far on a full charge than it did when new.

Carmakers back this with separate battery warranties, typically around eight years with a mileage limit, promising the battery will keep a set share of its original capacity. The exact terms vary by brand, so check the handbook for your car.

How you charge makes a difference too. Our guide to battery degradation covers what wears a battery and how to slow it down.

Do you need a longer charging cable for a long range car?

The car's range has nothing to do with cable length. What matters is the distance from the charge point to the car's charge port, and big long range SUVs often park further from the wall.

Measure from the charge point to the charge port along the route the cable will actually run, then add a couple of metres of slack. Most drivers find 5m enough on a drive. A car parked nose in with a rear charge port, or on a long drive, often needs a 10m cable or a 15m cable.

Always use one continuous cable. Never join two charging cables or charge through a household extension lead. Our guide to EV charging cable types covers Type 1, Type 2, amperage and length in full.

Final thoughts

For most people, chasing the biggest range figure is the wrong goal. The average driver covers under 20 miles a day, and a 250 mile car already handles a full week of that on one charge.

A 400 or 500 mile car earns its price if you do long motorway days or cannot charge at home. For everyone else, a smaller, more efficient car with good home charging will cost less to buy, less to run and fill up faster overnight.

Whatever you drive, the right cable decides how quickly that range comes back. Find the correct lead for your model in our Type 2 charging cables, or ask our team and we will tell you which one fits.
