Range is the number most people look at first when comparing electric vehicles. It is the figure that dominates manufacturer marketing, appears in every review headline, and sits at the centre of almost every conversation about whether EVs are practical for a given driver’s life.
The range figure quoted by manufacturers and the range a driver actually experiences are often meaningfully different, though. Understanding why that gap exists, and understanding what a well-designed EV interface should tell you about range, is more useful than simply memorising which EV has the longest range on a specification sheet.
This post covers both. It looks at the EVs with the best real-world range available in 2025, explains the factors that cause range to vary in practice, and examines what the design of range displays in current EVs gets right and where it still falls short.
Why Range Figures Are More Complicated Than They Look
Before getting to specific vehicles, it is worth understanding why the answer to which EV has the longest range is more complicated than it first appears.
Manufacturer range figures in the UK and Europe are based on the WLTP test cycle, which stands for Worldwide Harmonised Light Vehicle Test Procedure. This is a standardised laboratory test designed to give a consistent and comparable figure across vehicles. It is more realistic than the older NEDC test it replaced, and it still tends to produce figures that most drivers will not achieve in real-world conditions.
Speed is one of the most significant factors affecting real-world range. Aerodynamic drag increases with the square of speed, which means motorway driving at 70mph consumes considerably more energy per mile than the mixed urban and rural driving that the WLTP cycle is built around. Temperature matters significantly too.
Lithium-ion batteries lose capacity in cold weather, and heating the cabin in winter draws from the same battery that powers the drivetrain. Air conditioning in summer has a similar though less severe effect. Driving style, terrain, tyre pressure, and how much weight the vehicle is carrying all contribute as well.
The gap between WLTP figures and real-world range for most EVs in typical UK conditions is roughly 15 to 25 percent. A vehicle with a WLTP figure of 300 miles might deliver 230 to 255 miles in mixed real-world driving, and less on a cold winter motorway run. This context is essential for anyone deciding which EV car has the longest range for their specific needs.
The EVs With the Longest Range in 2025
With that context in place, the vehicles that lead on real-world range in 2025 sit in a relatively small group of premium and near-premium models.
The Mercedes EQS sits at or near the top of most range comparisons. Some variants carry a WLTP figure above 400 miles, and real-world performance holds up well for its class of driving. It achieves this through a combination of a very large battery pack and exceptional aerodynamics, including a drag coefficient that was the lowest of any production car when it launched.
The BMW i7 and the Lucid Air are also consistently near the top of the rankings for which electric vehicles have the longest range, both delivering real-world figures comfortably above 300 miles for drivers who do most of their driving outside of motorway conditions.
In the more accessible price bracket, the Tesla Model S Long Range and the Hyundai IONIQ 6 with its
rear-wheel-drive long-range variant both deliver real-world ranges that exceed 300 miles for many drivers. The IONIQ 6 is particularly notable because it achieves this through aerodynamic efficiency rather than simply fitting the largest possible battery, making it one of the more thoughtful answers to the question of what ev has the best range.
Among SUVs and crossovers, the Mercedes EQS SUV, the BMW iX xDrive50, and the Kia EV9 give the most convincing answers to which ev has the longest range uk buyers in this segment are looking for, though all involve trade-offs between range, performance, and price. Any of these vehicles will comfortably handle the majority of UK driving without range being a daily concern.
What Real-World Range Looks Like for Most Drivers
The vehicles listed above represent the upper end of the range spectrum, and for most drivers, knowing which ev car has the longest range matters less than knowing whether a given vehicle has enough range for their specific life.
The average UK driver covers around 20 to 25 miles per day. Even the most range-limited mainstream EVs in 2025 offer well above 150 miles of real-world range, meaning that for the vast majority of daily driving, range is simply not a practical constraint for home-charging drivers.
Where range becomes a genuine consideration is on longer journeys, specifically trips above roughly 150 to 200 miles where a charging stop becomes necessary. For those journeys, more range means fewer stops and more flexibility about where to stop. For a driver who regularly makes long trips, the difference between a 200-mile real-world range and a 300-mile real-world range is meaningful. For a driver whose longest regular journey is 80 miles, it is largely irrelevant.
The practical approach is to calculate the range needed for the journeys that actually matter to you, add a reasonable buffer for weather and driving style variation, and look for vehicles that meet that threshold. Paying a significant premium for range beyond what your usage requires is a common and easily avoided mistake.
The Interface Problem: What Your EV Is Telling You About Range
This is where the range conversation gets interesting from a design perspective, because the number displayed on an EV dashboard is not a simple fact. It is an estimate, derived from the battery’s current state of charge and a model of how that charge will be consumed based on recent driving patterns, current conditions, and assumptions about what comes next.
Different manufacturers make different design choices about how to present this estimate, and those choices have significant consequences for how drivers feel behind the wheel.
The simplest approach is to display a single number: estimated remaining range in miles. This is clean and easy to read, and it has a significant drawback. Because the estimate is continuously updated based on conditions and behaviour, it fluctuates. A driver who accelerates hard will see the range figure drop faster than expected. Moving from urban to motorway driving will cause it to fall more quickly. Switching on heated seats and a rear demister on a cold morning can cause the figure to drop ten or fifteen miles in a few minutes without the car moving.
For experienced EV drivers, these fluctuations are understood and mostly ignored. For newer drivers, they contribute directly to range anxiety, the persistent low-level worry that the battery will run out before reaching the destination. Watching a figure that showed 180 miles drop to 155 in the first twenty minutes of a motorway run is genuinely unsettling if you do not understand why it is happening.
A more considered interface approach, which some manufacturers have adopted, is to display a range band rather than a single figure. Instead of showing 187 miles, the interface shows a range between 160 and 210
miles, communicating that the actual outcome depends on conditions and driving style. This is more information, and it is more honest information. It sets an expectation rather than presenting a false precision, and it reduces the anxiety that comes from a single number behaving in ways that feel unexplained.
Information Hierarchy and the Range Display
The range figure is one of the most important pieces of information available to an EV driver. Whether the driver reaches their destination or needs to stop and charge depends meaningfully on understanding their range accurately.
Given that importance, it is striking how inconsistently range information is treated across current EV interfaces. In some vehicles it gets the same visual weight as the cabin temperature setting. In others it is buried in a submenu that requires deliberate navigation. In a small number of vehicles, it is given the prominence it deserves through size, position, and the additional context needed to interpret it accurately.
This is a design systems problem as much as it is a UX problem. When the token decisions governing typography scale, colour roles, and component hierarchy are not tied to the cognitive importance of the information being displayed, the result is interfaces where everything looks equally important. Battery state and media player status end up at the same visual level, and neither is served well by that.
Good range display design requires understanding the driver’s mental model and decision-making process. In normal driving well within range of home or a charge point, a quiet background display is appropriate. As the driver approaches a point where a charging decision needs to be made, the interface should become more prominent and more informative, showing not just the number but where the nearest charging options are and how long a stop would take. This kind of contextual, adaptive information design is achievable with current hardware. It is a design problem waiting to be solved properly.
Conclusion
The question of which EV has the longest range has a clear enough answer in 2025 for drivers who genuinely need maximum range above all else. For most drivers, the more useful question is whether a given vehicle has enough real-world range for the journeys that matter to them, and whether its interface gives them the information they need to use that range with confidence.
The best EV is not always the one with the longest range figure on the specification sheet. It is the one whose range, interface, charging experience, and overall design work together to eliminate the uncertainty and anxiety that still characterise EV ownership for too many drivers. That is a design problem as much as an engineering one, and it is one the industry is still working to solve properly.
