My neighbour called me on a Sunday evening, from a Carrefour car park in Uccle. He was looking for a first electric car for his wife, maximum budget €20,000. He'd seen an ad for the Dacia Spring and another for the BYD Dolphin. "What's the difference, apart from the price?"

The difference is almost everything. Here's why.

What is the real price difference between the BYD Dolphin and the Dacia Spring?

The Dacia Spring starts at 16,990 € in Belgium. That's the lowest price on the new electric market, full stop.

The BYD Dolphin is listed at 35,490 € catalogue, but BYD regularly offers commercial discounts of 6,500 €, bringing the real price to around 28,990 to 29,000 € for private buyers — check current offers at your Belgian BYD dealer.

The real gap: around 12,000 €. That's a lot. But before concluding that the Spring is the better choice, let's see what that difference buys you.

What real-world range should you expect from each model?

The manufacturer figure is fine. The real figure is this:

Dacia Spring: 225 km WLTP, but 165 km in mixed Belgian conditions. On the motorway at 120 km/h in winter, expect 120 to 130 km. For Brussels–Ghent or Brussels–Liège on the motorway, a charge stop is required — and DC charging is capped at 30 kW maximum (56 minutes from 10 to 80%). That's not comfortable.

BYD Dolphin: 427 km WLTP, 320 to 340 km in mixed conditions. The 60.4 kWh Blade battery and DC charging up to 88 kW allow you to go from 10 to 80% in 35 minutes. Brussels–Brussels via the Ardennes without stress.

Is safety really that different?

Yes, and it's the point I should have mentioned first. The Dacia Spring received 1 star in the Euro NCAP tests. The BYD Dolphin gets 5. If you're looking for a second car purely for urban commuting by a single adult driver, it's debatable. If it's for your wife, your children, the family — it's an argument that counts.

BYD includes as standard on the Dolphin: adaptive cruise control, lane-keeping assist, sign recognition, 360° camera. The Spring 2026 has made progress, but still lags behind on this front.

Who should choose the Dacia Spring?

In practice, the Spring makes sense in one specific scenario: 100% urban and peri-urban use, guaranteed home charging, and not a euro more to spend.

If you live in Brussels, your daily commute rarely exceeds 50 km, you have access to a plug or wallbox, and you're looking for the lowest total cost over 5 years — the Spring is an honest answer.

It's less so if you plan to use it to drive Brussels–Belgian Coast with the family on a Friday evening. The 30 kW DC charging turns every stop into a forced pause.

Who should choose the BYD Dolphin?

Everyone who wants mixed use — city and national roads and the occasional weekend getaway — without sacrificing safety or charging convenience.

The Dolphin was named Electric Family Car of the Year 2024 by the VAB (Flemish automobile club). That's not insignificant. For a Belgian family looking for their first versatile electric car under 35,000 €, it's the most complete model in its category.

The Spring is honest: it tells you what it is. A city car at a rock-bottom price. The problem is that many buyers take it for something else.

Verdict — which one to choose in Belgium?

Choose the Dacia Spring if: maximum budget 18,000 €, daily use under 80 km, home charging, zero regular motorway requirement.

Choose the BYD Dolphin if: you want a versatile electric car under 30,000 €, with real range, fast charging and 5-star NCAP. That's 12,000 € more upfront, but over 5 years, the TCO difference narrows significantly thanks to near-zero running costs and the battery's superior efficiency.
