Thirty thousand kilometres a year. That's the threshold where colleagues start saying "you drive too much to go electric." In Belgium, it's also the typical profile of a fleet manager, a sales rep shuttling between Brussels, Ghent, Antwerp and Liège, or a consultant visiting clients every week.
I ran the numbers. The result goes against the grain: the more you drive, the more an EV pays off. Not despite the mileage — because of it.
Why do high-mileage drivers have the most to gain from going electric?
The per-kilometre cost of an EV is structurally lower than that of a combustion car. And that gap multiplies with every kilometre driven.
At EUR 0.25/kWh on home charging (Belgian residential rate, CREG Q2 2026) and 15 kWh/100 km real-world consumption, each EV kilometre costs EUR 0.038 in energy. A diesel at 6.5 l/100 km and EUR 1.75/l runs to EUR 0.114 — three times more.
Over 30,000 km/year:
| Item | EV (home charging) | Diesel (D-segment) |
|---|---|---|
| Energy/fuel | EUR 1,125 | EUR 3,413 |
| Annual maintenance | EUR 450 | EUR 1,100 |
| Tyres (1 set/year) | EUR 650 | EUR 500 |
| Road tax (Brussels) | EUR 101 | EUR 500 |
| Total annual running cost | EUR 2,326 | EUR 5,513 |
The difference: EUR 3,187 per year, or EUR 265 per month. Over five years, that's nearly EUR 16,000 less in running costs — enough to cover a significant chunk of any initial purchase premium, if there still is one.
Does the battery keep up at 30,000 km per year?
This is the question that comes up every time. At 30,000 km/year, you hit 150,000 km in five years, 210,000 km in seven. Is the battery built for that?
The data says yes. The Geotab study (2025), tracking 22,700 electric vehicles over ten years, measures average degradation of 0.7 percentage points per 10,000 km. At 30,000 km/year, that works out to roughly 2% loss per year.
In plain terms: after five years and 150,000 km, an EV retains on average 90% of its battery capacity. On a 75 kWh model, that means 67.5 kWh usable — enough for 350 km of real-world mixed range. Not perfect, but entirely functional.
Two factors protect high-mileage drivers:
- Manufacturer warranties cover high mileage. Hyundai and Kia guarantee 8 years / 160,000 km, Tesla 8 years / 200,000 km (Model Y), BMW and VW 8 years / 160,000 km. A high-mileage driver at 30,000 km/year is still under warranty after five years.
- The Euro 7 standard (applicable from November 2026 for new models) mandates 80% capacity at 100,000 km and 72% at 160,000 km. Manufacturers are therefore engineering batteries to exceed these thresholds.
What are the 5 best EVs for high mileage in Belgium?
For a high-mileage driver, three criteria matter more than for any other profile: motorway efficiency (because the mileage often piles up on the E40 or E19), charging speed (to minimise time lost on the road) and battery durability.
Tesla Model Y Long Range — The rational choice
The Model Y Long Range delivers 600 km WLTP from its 78.1 kWh NMC battery. In real-world conditions on Belgian motorways at 120 km/h, expect 400-440 km. For sales reps: the Supercharger network is the densest in Belgium (Laeken, Zaventem, Ghent, Antwerp, Liège, Namur, Mons).
Measured consumption (ADAC, 2025): 16.9 kWh/100 km mixed, 22.2 kWh/100 km on the motorway. DC charging 10-80% in 27 minutes (250 kW). Over 30,000 km/year, the energy cost on home charging comes to EUR 1,268.
The decisive edge: OTA updates. After 100,000 km, the Model Y has the same interface, the same features — sometimes more — as on delivery day. No software ageing.
Peugeot E-3008 Long Range — The range champion
700 km WLTP thanks to a massive 96.9 kWh battery. In real-world motorway conditions, that translates to 450-490 km. It's the EV that comes closest to diesel-like range. For a sales rep covering Brussels-Luxembourg (220 km) or Brussels-Lille (120 km) in a day, that's a return trip on a single charge.
DC charging 10-80% in 30 minutes (160 kW). The 400V architecture limits charging power compared to 800V platforms, but the battery size compensates: even at 160 kW, kWh flow quickly into a 97 kWh tank.
520-litre boot. i-Cockpit driver's position. 8-year / 160,000 km battery warranty. This is a car built to eat kilometres.
Hyundai IONIQ 5 Long Range 84 kWh — Ultra-fast charging
800V architecture as standard. 10-80% charging in 18 minutes (350 kW). On a professional trip with a charging stop, that's the time for a coffee, not a lunch break.
Real-world motorway consumption (ADAC, 2025): 23.1 kWh/100 km — fair for a 2-tonne crossover. Real-world mixed range: 370-420 km. The charging power to battery capacity ratio makes it the EV best suited to 400-500 km days with short stops.
8-year / 160,000 km battery warranty. Geotab data on first-generation IONIQ 5s shows 93% remaining capacity after 80,000 km — reassuring for a vehicle heading towards 200,000 km in seven years.
Kia EV6 GT-Line 77 kWh — The sporty 800V alternative
Same E-GMP platform as the IONIQ 5, same 800V architecture, same unbeatable charging times. The Kia EV6 stands apart with a lower profile, a Cx of 0.28 (better than the IONIQ 5 at 0.29) and slightly lower motorway consumption: 22.5 kWh/100 km (ADAC, 2025).
WLTP range: 528 km. Real-world mixed: 380-420 km. For the driver who wants driving enjoyment on top of efficiency, the EV6 is the right compromise. Kia's 7-year warranty is a strong argument for a high-mileage vehicle.
Volkswagen ID.7 Pro S 86 kWh — The quiet cruiser
The ID.7 is Volkswagen's touring saloon. 86 kWh battery, 709 km WLTP, mixed consumption of 15.3 kWh/100 km (ADAC, 2025) — one of the lowest on the market for a car this size.
On Belgian motorways at 120 km/h: 20-22 kWh/100 km, delivering 400-440 km of real-world range. DC charging 10-80% in 28 minutes (200 kW). 532-litre boot — enough for a sales rep carrying samples.
Its quiet grand-touring profile doesn't make headlines, but it's exactly what a high-mileage driver needs: effortless kilometres.
What charging strategy works for a 30,000 km/year driver?
At 30,000 km/year — roughly 580 km per week — charging becomes a logistics question. The key: minimise time lost, not the cost per kWh.
Weekdays — Home or workplace charging. An 11 kW wallbox at home charges 60 kWh in 5h30 — more than enough to recover a 150 km day overnight. The Belgian home rate (EUR 0.22-0.30/kWh) is the cheapest option. For employees, workplace charging on a company 7-11 kW station is often free or employer-reimbursed.
On the road — DC fast charging. For 300-500 km days, a 20-minute DC stop (Ionity, Fastned, Supercharger) recovers 200-300 km depending on the model. In Belgium, motorway rest areas on the E40 (Wetteren, Bierbeek) and E19 (Kontich, Heverlee) are well equipped.
Annual charging budget at 30,000 km (70% home / 30% DC fast mix):
| Charging type | Share of km | Cost/kWh | Annual cost |
|---|---|---|---|
| Home (wallbox 11 kW) | 21,000 km | EUR 0.25 | EUR 788 |
| DC fast (Ionity/Fastned) | 9,000 km | EUR 0.45 | EUR 608 |
| Total | 30,000 km | — | EUR 1,396 |
Even with 30% fast charging at premium rates, the annual energy budget stays under EUR 1,400. The diesel equivalent: EUR 3,413.
How does 100% tax deductibility change the maths for a company car?
In Belgium, the company car is the high-mileage driver's vehicle of choice. And 2026 is the last year of 100% tax deductibility for new EVs.
What that means in practice: every euro spent on leasing, insurance, maintenance, tyres and charging for an EV company car is fully deductible from corporate tax. For a diesel or hybrid, deductibility ranges from 40% to 75% depending on emissions.
On an operational lease at EUR 700/month for a Tesla Model Y LR:
| EV (100% deductible) | Diesel (60% deductible) | |
|---|---|---|
| Gross annual lease | EUR 8,400 | EUR 7,200 |
| Tax saving (25% rate) | EUR 2,100 | EUR 1,080 |
| Net cost after tax | EUR 6,300 | EUR 6,120 |
The EV costs barely more in net terms — and fuel/energy costs are 2-3 times lower. On total TCO, the EV company car is cheaper from year one.
The BIK (benefit in kind) is another lever. For an EV, the minimum BIK is EUR 1,650/year in 2026 — compared to EUR 2,500-4,000 for an equivalent diesel. Lower BIK means less income tax for the employee.
What maintenance should you expect on a high-mileage EV?
No oil changes. No timing belt. No particulate filter. No clutch. An EV has structurally fewer wear parts than a combustion car — and it's at high mileage that the difference shows most clearly.
Typical maintenance schedule for an EV at 30,000 km/year:
- Every 20,000 km: cabin filter, brake check (pads last 80,000-120,000 km thanks to regenerative braking)
- Every 30,000 km: tyre rotation, suspension check
- Every 40,000 km: brake fluid replacement
- Every 60,000 km: HV battery health check (SoH diagnostic), AC dehydration filter replacement
Annual maintenance budget: EUR 400-600. For a diesel at 30,000 km/year, expect EUR 1,000-1,500 (oil changes every 20,000 km, filters, AdBlue, timing belt at 120,000 km, clutch at 150,000 km).
Tyres remain the costliest item. An EV wears its tyres 10-20% faster than a comparable combustion car, due to instant torque and the extra weight (300-500 kg of battery). At 30,000 km/year, plan for a full set annually: EUR 500-800 in 18-19 inch sizes.
5-year TCO comparison at 30,000 km/year
| Model | Belgian list price | Real consumption (mixed) | Energy 5 yrs | Maintenance 5 yrs | Tyres 5 yrs | 5-year TCO (excl. depreciation) |
|---|---|---|---|---|---|---|
| Tesla Model Y LR | EUR 48,000 | 16.9 kWh/100 km | EUR 6,338 | EUR 2,500 | EUR 3,250 | EUR 60,088 |
| Peugeot E-3008 LR | EUR 47,000 | 17.5 kWh/100 km | EUR 6,563 | EUR 2,750 | EUR 3,000 | EUR 59,313 |
| Hyundai IONIQ 5 LR | EUR 49,000 | 18.5 kWh/100 km | EUR 6,938 | EUR 2,250 | EUR 3,250 | EUR 61,438 |
| VW ID.7 Pro S | EUR 54,000 | 15.3 kWh/100 km | EUR 5,738 | EUR 2,750 | EUR 3,250 | EUR 65,738 |
| BMW 330d xDrive | EUR 55,000 | 6.8 l/100 km | EUR 17,850 | EUR 6,500 | EUR 2,500 | EUR 81,850 |
The BMW 330d, a benchmark for high-mileage diesel drivers, costs EUR 20,000 more in TCO over 5 years than the Tesla Model Y LR. This calculation doesn't even account for tax deductibility, which further favours the EV as a company car.
Factoring in depreciation, the gap narrows slightly: EVs depreciate 35-45% over 5 years (except Tesla, around 30%), versus 40-50% for diesels. But total TCO remains clearly in favour of electric.
