Electric SUV or sedan: which body style to choose?

The Belgian EV market is split between two body styles: SUVs and sedans. In practice, choosing between them comes down to a trade-off between energy consumption, cargo space and driving comfort — not fashion. An electric SUV uses 15-20% more energy than a sedan on the motorway. On the E40 between Brussels and Ghent, that means 1.5-2 kWh extra per 100 km. Over a year, it adds up.

Why does an electric SUV use more energy than a sedan?

Aerodynamics. An SUV has a frontal area of 2.7-2.9 m², versus 2.2-2.4 m² for a sedan. At 120 km/h on the E40, air resistance accounts for 70% of total consumption. The Cx × frontal area product — the real indicator — is 25-35% higher on an SUV.

In concrete terms: the Hyundai Ioniq 6 (sedan, Cx 0.21) uses 14.3 kWh/100 km on the WLTP cycle. The Hyundai Ioniq 5 (SUV, Cx 0.288), built on the same E-GMP platform with the same 77.4 kWh battery, uses 16.8 kWh/100 km. At 120 km/h on a Belgian motorway, the gap widens to 18 vs 22 kWh/100 km according to ADAC 2025 measurements.

Weight matters too, but less than you might think. The Ioniq 5 weighs 1,985 kg versus 1,895 kg for the Ioniq 6 — a 90 kg difference. On the flat stretch between Brussels and Liège, those 90 kg cost barely 0.3 kWh/100 km. The aero profile is what really drives the bill.

Which body style offers more usable space in Belgium?

The SUV wins on boot volume; the sedan surprises on rear habitability. The Skoda Enyaq 85 offers 585 litres of boot space versus 401 litres for the Tesla Model 3. But the Hyundai Ioniq 6 provides 980 mm of rear legroom, compared to 955 mm in the Ioniq 5. The sedan beats the SUV on its own platform.

In Belgium, boot space is a deciding factor for families making the Brussels-to-Belgian-coast run with a buggy, beach umbrella and cool box. An SUV like the Ioniq 5 or Enyaq swallows everything without a game of Tetris. The sedan forces compromises if you travel with two kids and a dog.

For a couple or solo commuter on the E19 between Brussels and Antwerp, the sedan is more than enough. The range advantage offsets the smaller boot.

What about parking in Brussels?

Height is the real issue. A Tesla Model 3 stands 1.44 m tall, an Ioniq 6 at 1.50 m. Both fit in every Brussels underground car park (standard limit: 1.90 m). A BMW iX reaches 1.70 m, a Kia EV9 nearly 1.78 m. In older car parks in the Pentagon district or Saint-Gilles, that can be a problem.

Length is less of an issue: most compact electric SUVs (ID.4, Enyaq, Ioniq 5) measure 4.60-4.68 m, comparable to sedans (Model 3: 4.72 m, Ioniq 6: 4.86 m). The sedan is sometimes even longer.

How much does an SUV vs a sedan cost in Belgium?

At comparable trim levels, the SUV costs €2,000-5,000 more than the equivalent sedan. But direct comparison is tricky: there isn't always a sedan/SUV twin on the same platform.

The Tesla Model 3 LR is the cheapest sedan per km of range: 629 km WLTP for ~€44,990, or ~€71 per WLTP km. The Skoda Enyaq is the most balanced SUV: 560 km for ~€43,500, or ~€78 per WLTP km.

What about the BIK for company cars?

The BIK (benefit in kind, known as ATN in Belgium) is calculated on catalogue value. For an EV, the formula is: catalogue value × 4% × 6/7 × age coefficient. Both a Model Y at €47,990 and a Model 3 LR at €44,990 fall below the 2026 floor threshold of ~€49,300, so the BIK is the same minimum: ~€1,690/year.

Above that threshold, every extra euro of catalogue value increases the BIK. A BMW iX xDrive50 at €84,000 gives a BIK of ~€2,880/year — roughly €100/month net more than a €45,000 sedan. For high-budget company leases, the sedan is more tax-efficient.

Do you need an SUV for Belgium's rough roads?

Not necessarily. An electric SUV's ground clearance (160-200 mm) helps with Walloon potholes, but most modern sedans manage fine if ground clearance exceeds 140 mm. The Tesla Model 3 (138 mm) handles country roads between Namur and Dinant without scraping, as long as you don't hit the worst speed bumps at full speed.

The SUV's real advantage on rough roads is suspension travel — typically 20-30 mm more than a sedan. The SPW (Wallonia's public works agency) logged 4,800 pothole reports in 2024 in Wallonia alone (Roads Directorate, 2024 annual report). If you drive daily on poorly maintained Walloon communal roads, the SUV delivers noticeably better comfort.

But if your trips are mainly motorway (E40, E19, E411) and city (Brussels, Antwerp, Ghent), the sedan uses less energy and the SUV's comfort edge is marginal on fresh tarmac.

What about towing?

The SUV is the only realistic option. Most electric sedans aren't rated for towing at all. The Tesla Model Y tows up to 1,600 kg, the Ioniq 5 up to 1,600 kg, the Skoda Enyaq up to 1,200 kg. If you need to haul a utility trailer to the recycling centre (recypark) or tow a bike van, the SUV is the way to go.

How to choose between SUV and sedan based on your profile?

There's no universal answer. The decision comes down to three practical criteria.

Commuter on the Brussels–Antwerp/Ghent corridor (mostly motorway): the sedan. Better range and lower consumption save €200-350 per year in electricity (based on 20,000 km/year at €0.35/kWh, with a 2.5 kWh/100 km gap). A 400-560 litre boot is enough for a gym bag and a laptop.

Family with children, mixed city + weekend driving: the SUV. A 530-850 litre boot handles family logistics. The raised driving position makes installing child seats easier. And the towing capacity is a bonus for holidays.

Couple without children, tight budget: the sedan. At the same price, it delivers 80-120 km of extra range. The Tesla Model 3 LR remains the best range-per-euro on the Belgian market as of June 2026.

The real test: list your five most frequent trips. If more than three involve loading the boot to capacity, get the SUV. Otherwise, the sedan does the job for less per kilometre.
