Electric vehicles have quietly introduced a driving technique that would have seemed impossible a generation ago: bringing a car to a complete, controlled stop without ever touching the brake pedal. It's called one-pedal driving, and it has moved from a curiosity among EV early adopters to a genuine operational consideration for UK fleet managers now overseeing more than two million battery-electric cars on Britain's roads.
With fleets now accounting for around six in ten new car registrations in the UK, and battery electric vehicles reaching a 30% share of the new car market in mid-2026, one-pedal driving is no longer a niche feature buried in an owner's manual. It's a technology with real implications for range, running costs, brake maintenance budgets, driver training programmes, and, as some recent UK data suggests, a few surprises that fleet managers should know about before they roll it out across a depot.
This guide explains what one-pedal driving is, how it works, what the evidence says about its benefits and risks, and what it means in practice for anyone responsible for a UK fleet in 2026.
What is one-pedal driving?
One-pedal driving is a mode available on most electric and some plug-in hybrid vehicles that allows a driver to accelerate, decelerate, and in many cases come to a complete stop using only the accelerator pedal. Press it, and the car speeds up as normal. Ease off, and instead of simply coasting, the car actively slows down, often firmly enough to bring it to a full stop without any input from the brake pedal.
It goes by different names depending on the manufacturer: Nissan calls it e-Pedal, Hyundai uses i-Pedal, General Motors calls it One-Pedal Driving, Ford has One-Pedal Drive, and Polestar and others simply refer to One Pedal Drive.
Although the branding varies, the underlying technology is the same across virtually every EV on sale in the UK today, including popular fleet choices like the Tesla Model 3, Nissan Leaf, Kia EV3/EV6, Hyundai Ioniq 5, and the growing range of electric vans from Ford, Vauxhall, and Mercedes-Benz.
Regular hybrids that can't drive on electric power alone typically don't offer true one-pedal driving, even though they use similar regenerative braking technology, because the internal combustion engine remains the primary power source. Plug-in hybrids, however, often do offer it while running in electric-only mode.
How does one-pedal driving work?
The technology behind one-pedal driving is regenerative braking, which exploits a simple principle of physics: electric motors are reversible. Feed a motor electricity, and it spins, turning the wheels. But spin the motor using the car's own momentum, and it works in reverse, acting as a generator instead.
When a driver lifts off the accelerator in an EV with one-pedal driving enabled, the car's computer switches the drive motor into generator mode. This creates a deceleration-like resistance that the driver feels, similar to engine braking in a manual petrol car, but considerably stronger and fully adjustable. The kinetic energy that would normally be wasted as heat in the brake pads is instead converted into electricity and returned to the EV battery.
For a practical sense of scale, some EVs decelerate at roughly a fifth of full braking force through regenerative braking when the driver lifts off the accelerator, enough to bring the car to a smooth, gradual stop at a junction or traffic light without ever needing the brake pedal. If a driver needs to slow more urgently than the regenerative system alone can manage, the car automatically blends in the conventional friction brakes, so stopping power is never compromised.
Brake lights illuminate automatically during one-pedal deceleration, exactly as they would under normal braking, so other road users get the same visual warning that the car is slowing down. According to GOV.UK's official guidance on driving electric and hydrogen-powered vehicles, regenerative braking is "a significant efficiency feature that is an integral part" of zero-emission vehicles, and many allow drivers to adjust its strength to suit road conditions and driving style.
Most modern EVs also retain a conventional brake pedal that still works exactly as expected; pressing it engages a blend of regenerative and friction braking, and it remains the only appropriate tool for emergency stops.
The benefits of one-pedal driving: range, brakes, and smoother journeys
Extending range through energy recuperation
The most quoted benefit of one-pedal driving is range. By recapturing energy during every deceleration rather than losing it as heat, EVs with strong regenerative braking typically achieve 15–20% higher efficiency than vehicles relying mainly on friction brakes, with some fleet operators reporting recapture rates as high as 30% on downhill sections.
One well-cited academic study of the Chevrolet Bolt found a 5% overall energy recapture rate, translating into roughly an extra 13 miles of range, a modest but meaningful gain, particularly for stop-start urban driving where opportunities to regenerate are frequent.
For fleet operators running EVs on tight delivery schedules or multi-drop urban routes, that additional range can be the difference between comfortably completing a route and needing an unplanned mid-shift charging stop.
Reduced brake wear (and cleaner air)
Because one-pedal driving handles most everyday deceleration with the electric motor rather than friction brakes, conventional brake pads and discs are used far less. Fleet and commercial EV operators commonly report brake service intervals measured in years rather than tens of thousands of miles, a genuine maintenance cost saving that compounds across a large fleet.
There's an environmental dimension to this, too, which increasingly matters for fleets with sustainability commitments.
A 2025 study by EIT Urban Mobility and Transport for London, examining London, Milan, and Barcelona, found that battery electric vehicles reduce brake dust emissions by 83% compared with conventional cars, and cut total non-exhaust particulate pollution, brake, tyre, and road wear combined, by 38%.
Brake dust is a genuinely significant, and often overlooked, source of urban air pollution, and a UK Department for Transport-commissioned study by Ricardo confirmed that regenerative braking in EVs reduces particulate emissions even after accounting for the extra weight of EV battery packs.
A smoother, less fatiguing drive
Beyond the numbers, many drivers report that one-pedal driving simply feels easier once they've adapted to it. Constantly moving a foot between two pedals is genuine physical work over the course of a long shift, and human-factors research has found that one-pedal driving can reduce cognitive workload and increase perceived ease of driving in everyday conditions. For professional drivers covering high mileages in stop-start traffic, exactly the profile of many UK fleet operations, that reduction in fatigue is a real, if harder to quantify, operational benefit.
The challenges and limitations of one-pedal driving
No technology is without trade-offs, and one-pedal driving has some worth understanding properly before rolling it out across a fleet.
The learning curve
Drivers new to one-pedal driving typically need some time to adjust. The deceleration is stronger and more immediate than coasting in a petrol or diesel car, and getting the timing right, easing off the accelerator early enough and smoothly enough to glide to a stop rather than lurching, takes practice. Most manufacturers, and organisations like IAM RoadSmart, the UK's largest road safety charity, recommend drivers practise in a quiet car park before using the feature in traffic. The good news is that most drivers report acclimatising within a single day or a handful of journeys.
Winter and slippery conditions
This is one area where fleet managers operating in the UK's famously unpredictable weather need to pay particular attention. Because regenerative braking is applied through the drive wheels rather than distributed hydraulically across all four wheels like conventional brakes, it can behave differently on low-grip surfaces. If the braking demand from lifting off the accelerator exceeds the available tyre grip, the drive wheels can lose traction, a risk that's more pronounced on ice, standing water, or compacted snow.
Manufacturers including Polestar and General Motors explicitly recommend reducing or disabling one-pedal driving in slippery conditions, and most modern EVs use traction control and stability systems to automatically moderate regenerative braking when wheel slip is detected. But these systems, however sophisticated, cannot create grip that isn't there. For UK fleets operating in rural or exposed areas prone to ice and standing water, this is a genuine point to cover in driver briefings, particularly as we head into autumn and winter.
The safety debate: what the research actually says
One-pedal driving's safety credentials have been formally examined by regulators.
In the United States, a petition raising concerns about driver confusion and pedal misapplication in one-pedal driving systems was reviewed and ultimately denied by the National Highway Traffic Safety Administration, which found no basis to require design changes such as mandating a brake press to complete a full stop.
Academic research paints a more nuanced picture. A 2024 driving simulator study comparing one-pedal and two-pedal driving found that one-pedal mode produced a longer transition time between throttle and brake and greater uncertainty in exactly when a driver would apply the brake pedal, but that it was, on balance, associated with safer outcomes in the specific emergency scenarios tested, partly because drivers reacted faster overall. A separate 2025 cognitive-behavioural study found that one-pedal driving reduced perceived cognitive load and improved reaction times compared with conventional two-pedal driving, but also recorded a higher incidence of pedal misapplication, pressing the wrong pedal, than either conventional driving or an alternative joystick-based control scheme.
The takeaway for fleet managers isn't that one-pedal driving is unsafe; the balance of evidence, including formal regulatory review, doesn't support that conclusion. It's that, like any new control interface, it changes driver behaviour in ways that benefit from proper familiarisation, particularly for drivers who regularly switch between electric and conventional vehicles.
An unexpected new problem: underused brakes
Analysis by vehicle data firm CarHunch, based on more than 10 million UK MOT records, found that while EVs fail MOT tests for brake-related faults far less often than petrol and diesel cars, exactly as you'd expect given reduced wear, a different problem is now surfacing as early EVs reach their first MOT cycles: brake components that are barely used can develop surface corrosion, particularly in the UK's damp climate, because they're no longer being kept clean by regular friction.
As one industry expert put it, after fifty years of managing brakes to stop them wearing out, the industry now has to manage some of them to stop them doing nothing at all. The suggested fix is refreshingly low-tech: an occasional deliberate firm brake application, sometimes informally called a "Friday firm stop", to clear any surface oxidation and keep components exercised. It's a useful, practical addition to any fleet EV maintenance checklist, and a good example of how a new technology can introduce equally new and unexpected considerations.
What this means for UK Fleet Managers
Driver training
The single clearest theme across the available evidence is that structured driver training transforms outcomes, particularly for one-pedal driving and EV efficiency. This isn't a minor detail; it's arguably the most cost-effective intervention a fleet manager can make when transitioning to electric.
Royal Mail, which operates the UK's largest fleet, offers one of the best-documented examples. Since introducing its first electric vans in 2017, the organisation has built a tailored EV training programme covering regenerative braking, vehicle controls, and performance awareness, and has put more than 1,000 drivers through it. The unexpected bonus: drivers who completed the EV training subsequently showed a 31% improvement in fuel efficiency when driving conventional diesel vans too, because the course fundamentally changed how they thought about acceleration and braking.
The Energy Saving Trust's Ecodriving in EVs programme produced similarly strong results in a controlled trial: 67 drivers trained over three months achieved a 16% reduction in energy consumption and a 20% increase in effective range. More recent industry commentary from fleet consultancy Sogo Mobility suggests targeted EV driver training can cut energy use by 15–25%, often the difference between a route that's comfortably achievable on a single charge and one that isn't.
Cost-savings
The financial argument for getting this right is straightforward. Beyond the direct energy savings from efficient driving, reduced brake wear translates into meaningfully lower service, maintenance, and repair costs across a fleet's lifetime, a material consideration given that EVs already carry a higher upfront purchase price than equivalent combustion vehicles. For fleets reimbursing employees for home charging, it's also worth noting that HMRC's Advisory Electricity Rate, the tax-free reimbursement rate for business mileage, was split from March 2026 into 7p per mile for home charging and 15p per mile for public charging, reflecting the real cost difference between the two, and giving fleet managers another reason to encourage efficient driving that maximises range between charges.
Building one-pedal driving into fleet policy
Practically, this means fleet managers transitioning to EVs should treat driver familiarisation as a core part of the rollout, not an optional extra. Structured half-day or on-site sessions, IAM RoadSmart's EV Familiarisation course, for example, runs a three-hour session for two drivers at a time, covering regenerative braking, range management, and safe use in everyday work, are a modest investment set against the potential efficiency and safety gains.
Fleet policy should also explicitly address winter driving guidance, given the documented traction considerations, and maintenance schedules should be updated to include occasional deliberate brake use to prevent the corrosion issue outlined above, rather than assuming "less brake wear" simply means "less to think about."
One-pedal driving vs traditional driving
In a traditional car, lifting off the accelerator produces gentle engine braking at best; meaningful deceleration requires a deliberate, separate action, moving the foot to the brake pedal and applying pressure. Every one of those braking events converts the car's kinetic energy into heat at the brake discs, and that energy is lost.
One-pedal driving collapses acceleration and deceleration into a single, continuous input, and, crucially, recovers energy rather than discarding it. The physical actions required are different: smoother, more anticipatory, and reliant on early observation of the road ahead rather than reactive braking at the last moment. This is precisely why eco-driving principles that long predate EVs- reading the road ahead, avoiding harsh acceleration and braking, maintaining steady following distances- translate so naturally into effective one-pedal driving technique.
The one habit that genuinely doesn't transfer well is the assumption that lifting off the accelerator means simply coasting. Drivers moving between an EV with strong one-pedal regeneration and a conventional car, or an EV with the feature switched off, need a moment to recalibrate, which is exactly why familiarisation training matters most for fleets running mixed EV and combustion vehicle pools, or for drivers who alternate between company EVs and their own petrol or diesel cars.
Practical advice for Fleet Managers
For any UK fleet operator introducing or expanding electric vehicles, the evidence points to a clear, practical checklist:
Invest in structured familiarisation before drivers get the keys. The Royal Mail and Energy Saving Trust results make a compelling case that this pays for itself many times over, not just in range and brake savings but in a demonstrable safety dividend from more anticipatory driving.
Build winter-specific guidance into driver handbooks. Make clear when and how to moderate regenerative braking in icy or wet conditions, and don't assume this knowledge transfers automatically from summer driving experience.
Update maintenance schedules to reflect the realities of EVs, including the counterintuitive need to occasionally exercise underused brakes, rather than just monitoring wear on heavily used ones.
Communicate the real efficiency stakes to drivers. Energy savings of 15–25% from good technique are large enough to matter for route planning, charging schedules, and total cost of ownership, worth explaining in plain terms rather than leaving to chance.
Treat mixed fleets with particular care. Drivers switching between EVs and conventional vehicles benefit most from clear guidance on how braking behaviour differs between the two.
The road ahead
One-pedal driving is a rare example of a vehicle technology that genuinely delivers on several fronts simultaneously: better range, lower running costs, reduced air pollution, and, once drivers are properly trained, a strong safety record backed by formal regulatory review. The caveats are real but manageable: a learning curve, some care needed in winter conditions, and a newly discovered maintenance quirk around underused brakes that's easily addressed with a sensible policy update.
As the UK's fleet sector continues its shift toward electrification, with battery electric vehicles now representing three in ten new car registrations and fleets driving the overwhelming majority of that growth, one-pedal driving will only become more central to how professional drivers operate their vehicles day-to-day. Fleet managers who treat it as a genuine skill worth training for, rather than an automatic feature that takes care of itself, stand to get considerably more out of their electric fleets: in range, in maintenance budgets, and in driver confidence behind the wheel.
The single most useful next step for any fleet manager reading this is a simple one: check whether your current EV drivers have received any formal regenerative braking familiarisation. If the answer is no, that's the most cost-effective improvement available to you.
