Longest Range Electric Cars UK 2026: Real-World Miles, Ranked

Last verified: May 2026

How we ranked the longest-range electric cars

Rankings are based on WLTP combined cycle figures from manufacturer official UK specification pages, cross-referenced with WhatCar? Real Range test data where published. Only cars on sale new in the UK in 2026 are included.

WLTP is measured under UNECE Regulation 154 (the successor to NEDC), covering a 23.5km mixed-speed laboratory cycle conducted without climate control active. It replaced NEDC in 2017 to 2018 and provides a more consistent basis for comparing models. It is, however, a lab result — real-world driving will always return fewer miles, for reasons covered in the next section.

Where WhatCar? Real Range data is unavailable for a specific model, this guide states that clearly rather than quoting an estimated figure. The table below uses WLTP only, so each number is directly comparable.

WLTP versus real-world range — what to actually expect

WLTP stands for Worldwide Harmonised Light Vehicle Test Procedure. It runs for 23.5km across four speed phases — low, medium, high, and extra-high — at a controlled ambient temperature of 23°C, with the climate control switched off. This makes it consistent as a benchmark, but optimistic compared to UK driving conditions.

In mixed UK driving, independent real-world testing typically shows a 15 to 25% shortfall versus WLTP. WhatCar? Real Range — which uses a standardised UK route combining urban, A-road, and motorway segments — has consistently found results in this range across dozens of models. For motorway-only trips at 70mph, the shortfall rises to 25 to 30%, because aerodynamic drag increases with the square of speed.

Cold weather adds a further layer of reduction. Recurrent Auto's study of 30,000 vehicles across multiple years found an average range reduction of roughly 22% at 0°C, rising to around 30% at -7°C. The causes are two-fold: lithium-ion chemistry becomes less efficient at low temperatures, and cabin heating draws significant additional energy from the battery pack.

In practical terms: for a car with a WLTP figure of 400 miles, a reasonable real-world expectation in mixed UK summer driving is around 300 to 340 miles. On a cold winter motorway run, plan for closer to 260 to 280 miles.

Longest-range electric cars UK 2026 — comparison table

All WLTP figures from manufacturer UK spec pages. Prices correct at May 2026 — verify before purchase.

1. Mercedes-Benz EQS 450+ — 481 miles WLTP

The Mercedes-Benz EQS 450+ tops the UK market with a WLTP range of 481 miles from its 108.4 kWh usable battery. It is the only car on sale in the UK in 2026 to break the 460-mile WLTP barrier in a single-motor configuration.

No independent WhatCar? Real Range figure has been published for the EQS 450+ at the time of writing; however, real-world ownership data and European tests consistently suggest 360 to 400 miles in mixed conditions. The EQS benefits from a low drag coefficient of 0.20 Cd — one of the lowest of any production car — which is the primary reason for its exceptional official figure. It also includes a heat pump as standard.

The practical weakness is price: at over £104,600, it sits firmly at the luxury end of the market. Charging speed is also modest at 200kW DC maximum, meaning a 10 to 80% top-up takes around 31 minutes at the fastest public chargers.

Cost per mile at 7p off-peak: approximately 1.4p per mile (108.4 ÷ 481 = 0.225 kWh/mile × £0.07 = £0.016, or 1.6p).

2. Polestar 3 Long Range Single Motor — 438 miles WLTP

The Polestar 3 Long Range Single Motor ranks second in the UK with 438 miles WLTP from a substantial 111 kWh usable battery — the largest pack on this list.

No WhatCar? Real Range figure has been published for the single-motor Polestar 3 specifically, though the dual-motor variant returned around 300 miles in mixed motorway testing by Auto Express. The single-motor version is considerably more efficient, so real-world mixed figures of 330 to 370 miles are a reasonable expectation.

The Polestar 3 won the 2025 NAF El Prix winter test in Norway, demonstrating strong thermal management in sub-zero conditions. It includes a heat pump and a 250kW maximum DC charge rate. At £66,950, it is substantially cheaper than the EQS while covering comparable distances in most real-world scenarios.

Cost per mile at 7p off-peak: approximately 1.8p per mile (111 ÷ 438 = 0.253 kWh/mile × £0.07 = £0.018).

3. Porsche Taycan RWD Performance Battery Plus — 422 miles WLTP

The Porsche Taycan RWD with the Performance Battery Plus pack achieves 422 miles WLTP from 93.4 kWh usable capacity, making it the most efficient car per kWh in the top five.

No UK-specific WhatCar? Real Range result has been published for this variant. European and US real-world testing consistently returns figures in the 280 to 340 mile range in mixed driving, reflecting a roughly 20 to 25% reduction from WLTP — broadly in line with the class average.

The Taycan's 800V architecture is its most practical real-world advantage: it can accept up to 320kW DC at compatible chargers (Ionity, Osprey, some BP Pulse Ultra sites), meaning a 10 to 80% charge takes under 20 minutes. That directly reduces the real-world impact of its slightly lower range versus the EQS. The practical weakness at £74,900 is the premium over equivalent-range rivals.

Cost per mile at 7p off-peak: approximately 1.5p per mile (93.4 ÷ 422 = 0.221 kWh/mile × £0.07 = £0.015).

4. Tesla Model 3 Long Range RWD — 421 miles WLTP

The Tesla Model 3 Long Range RWD ranks fourth with 421 miles WLTP from just 75 kWh usable — making it the most efficient car on this list by a significant margin.

WhatCar? Real Range returned 330 miles for the Model 3 Long Range in its 2024 test cycle, representing a 21.6% shortfall versus WLTP. That remains one of the strongest real-world results of any car below £50,000.

The Model 3 LR includes a heat pump, consistent over-the-air software updates, and access to Tesla's Supercharger network — one of the most comprehensive in the UK. Maximum DC charge rate is 250kW. At £42,990, it is by far the most accessible car on this list and the default recommendation for buyers who want genuine long range without the luxury price tag.

Cost per mile at 7p off-peak: approximately 1.3p per mile (75 ÷ 421 = 0.178 kWh/mile × £0.07 = £0.012).

5. Tesla Model S Long Range — 394 miles WLTP

The Tesla Model S Long Range achieves 394 miles WLTP from a 100 kWh usable battery. It sits between the Polestar 3 and the BMW i7 in overall range, while offering the highest interior refinement of any Tesla.

No recent WhatCar? Real Range figure has been published for the current Model S generation at the time of writing. Recurrent Auto ownership data across thousands of US Model S vehicles suggests an average real-world retention of around 81% in mixed conditions, which would indicate roughly 319 miles in typical UK driving.

The Model S benefits from Supercharger V3 compatibility at up to 250kW and Autopilot as standard. Its practical weakness relative to the Model 3 LR is the price premium of around £42,000 for broadly comparable real-world range, making it a luxury purchase rather than a purely rational long-range choice.

Cost per mile at 7p off-peak: approximately 1.8p per mile (100 ÷ 394 = 0.254 kWh/mile × £0.07 = £0.018).

6. Polestar 2 Long Range Single Motor — 406 miles WLTP

The Polestar 2 Long Range Single Motor achieves 406 miles WLTP from a 78 kWh usable battery, placing it sixth in the overall ranking but second only to the Model 3 LR for efficiency at this price level.

WhatCar? Real Range testing returned 310 miles for the Polestar 2 LR in its standardised UK test. That represents a 23.6% shortfall from WLTP — average for the segment and a useful benchmark for planning motorway trips.

The Polestar 2 includes a heat pump on the Long Range Single Motor variant, contributing to its strong winter performance. It charges at up to 205kW DC. At £49,995, it occupies a middle ground between the Tesla Model 3 LR and the Porsche Taycan, offering Swedish build quality and a Google-native infotainment system. Its one practical limitation is a slightly narrower charging network than Tesla, relying primarily on Osprey, Ionity, and public third-party networks.

Cost per mile at 7p off-peak: approximately 1.4p per mile (78 ÷ 406 = 0.192 kWh/mile × £0.07 = £0.013).

7. BMW i7 eDrive50 — 388 miles WLTP

The BMW i7 eDrive50 achieves 388 miles WLTP from 101.7 kWh usable capacity. It is the longest-range luxury saloon from a German premium brand outside the Mercedes EQ range, and positions itself as a direct competitor to the EQS 450+.

No current WhatCar? Real Range figure has been published for the i7 eDrive50 at the time of writing. Real-world data from European press tests suggests figures of 270 to 310 miles in mixed motorway conditions — a slightly larger real-world deficit than the Mercedes EQS, attributable in part to the i7's more conventional saloon proportions and higher aerodynamic drag.

The i7 eDrive50 charges at up to 195kW DC, which is lower than several rivals at this price point. At approximately £105,000, it matches the EQS on price while offering BMW's traditional executive saloon driving experience and a longer, more lavish rear cabin. A heat pump is standard.

Cost per mile at 7p off-peak: approximately 1.9p per mile (101.7 ÷ 388 = 0.262 kWh/mile × £0.07 = £0.018).

8. Mercedes-Benz EQE 350+ — 382 miles WLTP

The Mercedes-Benz EQE 350+ achieves 382 miles WLTP from 90.6 kWh usable capacity. It uses the same MMA electric platform as the EQS but in a more compact saloon body, making it a more accessible entry into the EQ range at £66,800.

No independent WhatCar? Real Range result has been published for the EQE 350+ at the time of writing. Its drag coefficient of 0.22 Cd — close to the EQS's class-leading 0.20 — helps it retain a higher proportion of WLTP range than most rivals. Realistic mixed-driving estimates based on comparable platform models suggest 280 to 320 miles.

The EQE charges at up to 170kW DC, which is the practical limitation of this model. At motorway charging speeds, this means longer stops than the Taycan or Polestar 3 at comparable charge states. A heat pump is included as standard. The EQE sits at a similar price to the Polestar 3 while offering a more traditional saloon format.

Cost per mile at 7p off-peak: approximately 1.7p per mile (90.6 ÷ 382 = 0.237 kWh/mile × £0.07 = £0.017).

9. BMW i5 eDrive40 — 362 miles WLTP

The BMW i5 eDrive40 achieves 362 miles WLTP from 81.2 kWh usable capacity. It is the most affordable BMW on this list at £65,375 and combines a mid-size executive saloon format with competitive real-world efficiency.

WhatCar? Real Range returned 288 miles for the BMW i5 eDrive40 in its standardised UK test, a shortfall of 20.4% versus WLTP. That result puts it within a few miles of the Polestar 2 LR in real-world terms, despite a lower WLTP headline — a useful reminder that real-world and official figures do not always track proportionally.

The i5 eDrive40 charges at up to 205kW DC, on par with the Polestar 2. Heat pump is standard. It is the recommended choice for buyers who want a conventional executive saloon with genuine motorway range capability below £70,000.

Cost per mile at 7p off-peak: approximately 1.9p per mile (81.2 ÷ 362 = 0.224 kWh/mile × £0.07 = £0.016).

10. Hyundai Ioniq 6 Long Range RWD — 338 miles WLTP

The Hyundai Ioniq 6 Long Range RWD achieves 338 miles WLTP from 77.4 kWh usable capacity. It sits lowest on this ranking by WLTP figure, but ranks highest for real-world efficiency per kWh among cars under £50,000.

WhatCar? Real Range returned 277 miles for the Ioniq 6 Long Range RWD, a shortfall of 18% from WLTP — one of the smallest deficits of any car tested. Its ultra-low drag coefficient of 0.21 Cd, standard heat pump, and 800V charging architecture (up to 239kW DC) make it the most technically capable long-range car in its price bracket.

The practical limitation is the slightly lower WLTP ceiling versus rivals at this price point; the Hyundai's real-world figure of 277 miles is, however, more reliably achievable than the headline numbers of some rivals. At £40,945, the Ioniq 6 LR RWD is the most competitively priced car on this list and, alongside the Tesla Model 3 LR, the most practical recommendation for buyers prioritising genuine range on a realistic budget.

Cost per mile at 7p off-peak: approximately 1.3p per mile (77.4 ÷ 338 = 0.229 kWh/mile × £0.07 = £0.016).

What affects electric car range in the UK

Several factors reduce real-world EV range below the WLTP figure, and understanding them helps you plan more accurately.

Motorway speed. Aerodynamic drag increases with the square of speed, so moving from 60mph to 70mph raises drag by roughly 36%. WhatCar? Real Range testing finds an average 25 to 30% deficit versus WLTP at 70mph motorway cruising. Dropping to 60 to 65mph can recover 10 to 15% of that loss.

Cold temperatures. At 0°C, lithium-ion cells can deliver only around 78% of their rated capacity in high-current draw conditions (Recurrent Auto). A further drain comes from resistive cabin heating, which can draw 3 to 5 kW — comparable to the entire energy demand of steady 70mph cruising. Cars with heat pumps typically retain 8 to 12% more range in cold conditions.

Payload and roof accessories. A heavily loaded car or one fitted with a roof box increases frontal area and rolling resistance. A roof box at motorway speeds can reduce range by 8 to 15% depending on size and shape.

Tyre choice and wheel size. Larger alloys increase unsprung weight and aerodynamic drag. Narrower, higher-profile tyres on smaller rims consistently return better real-world range; the difference between the smallest and largest wheel option on the same car can be 10 to 20 miles WLTP.

Heat pump availability. Heat pumps move heat from outside air rather than generating it electrically, using up to 50% less energy than resistive heaters at temperatures above -5°C. They are now standard on many long-range models, but worth confirming on the specific trim you are considering.

How to get the most range from your EV

1. Pre-condition the battery while still plugged in at home. Warming the cabin and battery to operating temperature before you unplug means the energy comes from the grid rather than your battery pack, preserving 5 to 10% real-world range from the moment you leave.
2. Use eco mode and reduce climate control — or use seat heaters instead of cabin heat. Seat heaters typically draw 50 to 100W; a resistive cabin heater can draw 3 to 5 kW. Switching to seat heat alone can extend range by 15 to 25% in cold weather.
3. Keep to 60 to 65mph on the motorway rather than 70mph. This single adjustment can recover 10 to 15% of the motorway range penalty and is the highest-impact change most drivers can make.
4. Check tyre pressures monthly. Cold air drops pressure roughly 1 PSI per 5°C temperature reduction, which increases rolling resistance and reduces range. Under-inflated tyres by 5 PSI can cost 2 to 3% range.
5. Use one-pedal driving and strong regenerative braking. Regen returns energy to the battery on deceleration; in stop-start urban driving, this can offset 15 to 25% of energy consumed.
6. Plan charging stops for trips where you need more than 80% of the displayed range. Rapid charging slows significantly above 80% state of charge. Stopping at 20% and charging to 80% is both faster and better for long-term battery health than running to near-empty.

Frequently asked questions

Which electric car has the longest range in the UK?

As of 2026, the Mercedes-Benz EQS 450+ leads the UK market with a WLTP range of around 481 miles. In real-world mixed UK driving, expect roughly 360 to 400 miles depending on speed and conditions.

Can any electric car really do 400 miles on a single charge?

In WLTP terms, yes — the EQS 450+, Porsche Taycan RWD Performance Battery Plus, Polestar 3, Polestar 2, Tesla Model 3 LR, and Tesla Model S all exceed 380 miles on the official cycle. In real UK mixed driving, the most efficient of these will return roughly 300 to 350 miles.

How accurate is the WLTP range figure?

WLTP is typically 15 to 25% optimistic for mixed real-world driving, and 25 to 30% optimistic for motorway-only trips at 70mph. WhatCar? Real Range testing, which uses a standardised UK mixed-route cycle, gives the most reliable real-world comparison.

What is the most efficient electric car you can buy?

The Hyundai Ioniq 6 Long Range RWD and Tesla Model 3 Long Range lead on real-world efficiency in miles per kWh. High efficiency — not raw battery size — is the most reliable predictor of long real-world range.

Does cold weather really cut EV range?

Yes. Recurrent Auto data from 30,000 vehicles shows an average 22% range reduction at 0°C and up to 30% at -7°C. Cars with heat pumps, such as the Tesla Model 3 and Hyundai Ioniq 6, retain more range in winter than those with resistive heaters.
