The Greenfleet 2026 EV Rally busted a lot of myths around EVs. Over five days and more than 1,000 miles from Exeter to London, electric cars, vans and trucks did the job in real working conditions. Quartix was there as Official Technology Partner — measuring every vehicle across the route, and driving it alongside the teams. If you missed the results, they’re here.

But “EVs work” and “EVs work for my fleet” are two very different statements. The first is now hard to dispute. The second is a question only your own operation can answer — and the answer is already sitting in the data you collect every day.

This guide is the practical companion to that decision: how to assess EV readiness from the mileage, utilisation, location and driving data your vehicle tracking system already gathers — and how to get the most range from every EV once it’s on the road.

Busting myths and assessing suitability

Some of the doubts that hold fleets back were tackled head-on at the EV Rally, with the people who know the subject best:

• “EVs catch fire easily.” Addressed on day one with fire-safety experts.
• “Batteries just end up in landfill.” Countered at the UK’s first commercial EV battery recycling plant.
• “Used EVs can’t do the job.” Challenged by the real distances teams covered, day after day.
• “Electric trucks aren’t ready.” Answered by a fully laden 44-tonne electric HGV completing the route.

See the full recap here.

The questions that remain are more practical, and more personal to your operation:

• Can our vehicles complete their daily routes on a single charge?
• Where and when would they charge?
• Which vehicles should switch first, and which shouldn’t switch at all?
• Will the numbers add up?

These aren’t myths to bust. They’re facts to check. And every one of them can be answered from data you already have.

Assess your readiness in four checks

1. The range check: can each vehicle complete its day?

Range anxiety is usually a fear of the unknown, but your fleet’s daily mileage can help build the picture. Trip and mileage reports show how far each vehicle really travels on a typical day, week and month. Set those distances against the usable range of the EVs you’re considering. A van on a predictable 16-mile-a-day round is an obvious early candidate; a high-mileage motorway vehicle needs a closer look. Either way, you’re matching real distances to real range.

2. The charging check: where and when would they charge?

Public charging infrastructure may be widely available near your routes, but you want to know whether your vehicles can charge where they already stop. Live tracking and location history show where each vehicle ends its shift and how long it sits there. A vehicle that returns to the same depot or a team member’s home and stays put overnight can rely on slower, cheaper charging; one that rarely stops for long, or parks away from power, can be flagged at the planning stage. This points you to where charging needs attention rather than sizing the network for you.

3. The priority check: which to vehicles switch first

This is where fleets save the most money and it starts with a warning: don’t replace your fleet one-for-one.

The most expensive EV mistake is buying electric versions of vehicles you didn’t really need. Use utilisation data to find the vehicles that are barely working, right-size first — cut or reallocate the under-used ones — and only then electrify what you really need. The result is a smaller, cheaper, better-matched order.

Your vehicle utilisation report makes the under-performers obvious at a glance. An example report might read like this:

Vehicle	Monthly distance	Idling	What it tells you
Sprinter van	~480 miles	7%	Low mileage — an easy early EV win
Transit van	~1,420 miles	14%	Viable, but check the route pattern
Combo cargo	~2,150 miles	15%	High use and high idling — plan carefully

The dashboard’s usage charts make the same point visually, used versus unused vehicles each day, with the unused group listing the vehicles to reallocate first, not electrify.

4. The cost check: will it pay off?

Right-sizing is also the biggest single lever in the financial case: fewer vehicles bought outweighs any running-cost difference. Build the rest on your real diesel baseline — the mileage and fuel data your vehicle tracking system already records — against EV running costs. Our ROI calculator and fuel savings calculator turn those numbers into a payback picture you can take to your finance team.

Your EV-readiness checklist

Work through the four checks and you’ll have an evidence-based answer. Use this as a quick scorecard:

Check	You’re ready when…	Where the data lives
Range	Each candidate vehicle’s daily mileage fits comfortably within EV range	Trip and mileage reports
Charging	Candidate vehicles stop somewhere with power for long enough to charge	Live tracking and location history
Right-sizing	Under-used vehicles are cut or reallocated before any EV order	Utilisation report and usage charts
Cost	Your diesel baseline shows a workable payback against EV running costs	ROI and fuel savings calculators

Ready to switch doesn’t mean ready to run well

Passing these readiness checks tells you which vehicles can go electric. Getting the most from them afterwards is a separate, ongoing job. A lot of EV range is set by how a vehicle is driven and routed — the same data that we safety-scored every vehicle at the 2026 EV Rally.

Safer driving and better range pull in the same direction: a better driving style helps both. We believe safety and sustainability go hand in hand, a view we put forward at this year’s UK Fleet Champions Awards 2026.

Smoother driving means more range

Harsh acceleration and heavy braking drain an EV faster than almost anything else. Driver behaviour monitoring scores acceleration and braking second by second. Managers can click any harsh event to see exactly where it happened, so coaching is about a real moment on a real road instead of a vague instruction to “drive better.” Smoother deceleration also lets regenerative braking recover more energy, feeding range back into the EV battery.

The right speed, for more miles

Aerodynamic drag rises sharply with speed, so motorway habits have an outsized effect on how far an EV will go. Our unique SafeSpeed database scores each vehicle’s speed against the speed of other road users on the same stretch of road, regardless of the speed limit – giving a relative score. That not only gives a better measure of risk, but also makes it easy to spot where easing off the accelerator would stretch range, without slowing the working day.

Less wasted energy

An EV doesn’t idle an engine, but leaving it switched on and stationary still drains the traction battery to run heating, cooling and onboard systems. Idling reports surface that waste, and smarter routing through fleet management tools trims unnecessary miles. The mile you never drive uses no energy at all.

Making it stick: friendly competition and self-coaching

Insight only changes range if the people behind the wheel act on it, which is why the scores are built to engage rather than just report. Our colour-coded daily driver league table turns smoother driving into friendly competition, while each team member sees their own performance in the Quartix mobile app and can adjust naturally. It’s an approach customers see working for themselves:

The mileage, utilisation, location and behaviour data you already collect can answer the EV readiness question vehicle by vehicle — and then help you get the most range from every EV you add. It works just as well mid-transition, or across a mixed fleet, as it does for a fully electric operation with vehicles due for replacement.
