The 10 Longest-Range Used Electric Cars You Can Buy

The used market is now full of electric cars that top 400 miles on paper. Here are the ten longest-range used EVs in the UK, what they realistically deliver, and the one check that tells you what a specific car will still do.

Quick answer

The longest-range used electric car in the UK is the Mercedes-Benz EQS 450+, rated at up to 481 miles WLTP for 2024-on cars (up to 453 miles for 2021–23 examples). But the brochure figure belongs to the model, not the car in the advert: a used EV's real range depends on its battery health, so check the specific car before you buy.

Key takeaways

  • The Mercedes-Benz EQS 450+ leads the used market at up to 481 miles WLTP.
  • Several used EVs now clear 400 miles on paper, but typical real-world estimates run 15-25% lower.
  • The exact variant, model year and wheel size change the official figure materially.
  • The number that matters is the specific car’s range now vs when new, and you can check it from the registration.

How we ranked them

The table ranks cars by the official “up to” UK WLTP figure of the longest-range variant you can actually find on the UK used market. WLTP is the manufacturers' lab test and is optimistic, see real-world EV range explained, so alongside it we show the typical real-world estimate published by the independent EV Database. Both describe the car when new and healthy; a used example may deliver less. Figures are correct as of July 2026.

The standouts, and the traps

The EQS 450+ is the used range king either side of its facelift, even 2021–23 cars are rated at up to 453 miles, and heavy depreciation has made early examples surprisingly attainable. The Polestar 3 Long Range Single Motor certified an official 438 miles but was only sold for around a year before the 2026 line-up dropped the variant, so used examples are scarce. The Tesla Model 3 entry is the Long Range RWD sold from late 2024; a small number of late-2025 cars carry an improved 466-mile rating, while the far more common Long Range AWD is rated up to about 390–421 miles depending on year and wheels.

Two honesty prizes: the Porsche Taycan and Tesla Model S sit mid-table on paper but their ~355-mile real-world estimates beat several cars ranked above them. One trap: refreshed Model S cars sold in the UK from 2023 were left-hand drive, Tesla never built the update in RHD, so right-hand-drive used stock is the pre-2022 car with a lower rating. And every figure here is an “up to”: bigger wheels alone can trim 20–30 miles, the Polestar 2 Long Range drops from 406 to 379 miles on the larger rims.

Bubbling under the ten: the BMW i7 (up to 388 miles), Tesla Model Y Long Range RWD (387 miles, from mid-2025), VW ID.7 Pro (386 miles), Ford Mustang Mach-E Extended Range (up to 379 miles and used since 2021), and, at friendlier money, the BMW i4 eDrive40 (up to 365 miles) and Hyundai Ioniq 6 (338 miles).

Why a used example won't match these figures

These are when-new ratings. Every battery loses some capacity with age and mileage, so a used car's ceiling is lower than the brochure's, usually only modestly, but the spread between a cared-for battery and a tired one is exactly what you're buying blind. Cold weather, motorway speeds and driving style then take their share on the day. See why EVs lose range and what normal degradation looks like.

Check what the specific car still delivers

A long-range model with a degraded battery can be out-ranged by a shorter-range model with a healthy one, so the table should be the start of your shortlist, not the end of your homework. The Used EV Check estimates the expected real-world range now versus when new for the exact car, from just the registration, along with a degradation estimate, the remaining battery warranty and a battery-health grade where a manufacturer test record exists. Range data is powered by ClearWatt.

Range and battery-health figures are estimates modelled from real-world data and are shown for the specific vehicle in the Used EV Check. Range data is powered by ClearWatt. A battery-health grade is shown where a manufacturer test record exists, it is a comparative grade, not a measured state-of-health percentage.

Frequently asked questions

Which used electric car has the longest range?+
The Mercedes-Benz EQS 450+ has the longest official range of any EV commonly available used in the UK, up to 481 miles WLTP for 2024-on facelift cars and up to 453 miles for 2021-23 examples. Typical real-world estimates are lower, roughly 390-425 miles when new and healthy.
Is WLTP range accurate in the real world?+
No, treat it as a best case. WLTP is a lab test, and most drivers see roughly 75-90% of the official figure in everyday driving, with cold weather and motorway speeds cutting it further. That is why this ranking shows an independent real-world estimate alongside every WLTP figure.
How much range does a used EV lose as it ages?+
Batteries lose some capacity gradually with age and mileage, and the rate varies car to car depending on how it was charged and used. That variation is why two identical used EVs can have noticeably different real ranges, and why checking the specific car matters more than the model’s brochure figure.
How do I check a used EV’s real range before buying?+
Run a battery-health check from the registration. The Used EV Check estimates the expected real-world range now versus when new for that exact car, plus a degradation estimate, remaining battery warranty and a battery-health grade where a manufacturer test record exists. Range data is powered by ClearWatt.
