Which electric cars with 800V architecture are available in Belgium?

Brussels–Paris, charging stop at Cambrai. In an Ioniq 6, I plugged in at 11%. Twenty-two minutes later, I was at 80% and back on the road. In a friend's Golf GTI doing the same journey, the petrol stop took 8 minutes — but there was a queue, a coffee, and in the end 15 minutes lost. 800V architecture is what made that comparison possible.

Here is what it actually changes, and which models you can buy in Belgium today.

Why does 800V architecture concretely change the fast-charging experience?

Most electric cars run on 400V. That is sufficient for home charging at 7 kW or on a DC charger up to 100 kW. The problem is heat: to increase charging power, you need to increase the current intensity in the cables. And high current means heat.

At 800V, the same power flows with half the amperage. Less heat in the cables, lighter cross-sections, and the ability to reach 270 to 400 kW without overheating or oversized cables. This is not marketing — it is basic physics that translates into 20-minute motorway stops instead of 45.

In practice, on a 350 kW charger:

• 100 km recovered in 10 minutes
• 10% to 80% in 18 to 22 minutes depending on the model
• Power remains high over a wider state-of-charge range, without the abrupt drop at 50% that penalises some 400V cars

Which 800V models are available to buy in Belgium in 2026?

Why did Hyundai and Kia democratise 800V outside the premium segment?

The E-GMP (Electric Global Modular Platform) from Hyundai Motor Group was the first to make 800V accessible outside the premium segment. Launched in 2021, it equips four models sold in Belgium.

Is the Mercedes CLA the best price/fast-charging ratio in 800V in 2026?

Does the Porsche Taycan remain a relevant 800V reference in 2026?

Which Audi models offer 800V via the PPE platform?

The PPE (Premium Platform Electric) platform is the result of the Audi/Porsche collaboration. It brings 800V to premium segment SUVs and saloons.

Which 800V models are arriving in Belgium in late 2026 and early 2027?

How to identify fake 800V cars among manufacturer marketing claims?

"800V" has become a marketing argument that some manufacturers use with considerable freedom.

Peugeot e-3008: it regularly appears in lists of 800V cars online. It is not one. It is a 400V with DC power limited to 160 kW on the spec sheet — and real-world tests on Ionity chargers have sometimes measured less than 50 kW effective. It is a decent car, but if you buy it counting on 800V charging times, you will be disappointed.

BYD and XPeng: some models display "800V" in their brochures. Check the official spec sheet — the batteries sometimes run at significantly lower voltages. The label may refer to the inverter or motor, not the battery pack.

Tesla Model 3 and Y: 400V, up to 250 kW on Supercharger V3. Not 800V. But the Supercharger network remains the densest and most reliable in Belgium — it is a rational choice for high-mileage drivers.

The simple rule: if the manufacturer does not cite DC charging above 250 kW with a 10–80% time under 25 minutes in its official spec sheet, look past the "800V" label.

Which high-power chargers are compatible with 800V EVs in Belgium?

800V only makes sense if the chargers keep up. In Belgium in 2026, high-power charging remains concentrated on motorway routes:

• Ionity: 350 kW chargers on the main routes (E40 Liège–Brussels, E411 towards Namur, E17 Ghent–Antwerp). Around twenty stations.
• Fastned: 300 to 400 kW at motorway exits, expansion ongoing.
• Total Energies: 300 kW deployed at several sites.
• Q8 Charge: a few stations at 150 to 300 kW, integrated into service stations.
• Electra: deployment underway, 250 to 400 kW.

Before setting off on a long journey, check the available power at each stop using ABRP (A Better Route Planner). Some Ionity stations may be saturated at weekends, and arriving at 20% at an out-of-service station is still a scenario that happens.
