The electric family SUV market is booming, and two key players are vying for your attention. In one corner, we have the Volkswagen ID.4, a sensible, well-rounded EV from one of the world's most established car makers. It represents a safe and dependable step into electric motoring for families.
In the other corner is the BYD Sealion 7, a stylish and ambitious newcomer from a brand that's rapidly making a name for itself. With its sharp looks and focus on technology and space, it aims to challenge the old guard head-on. So, should you stick with the familiar favourite or take a chance on the new challenger?
BYD Sealion 7 vs Volkswagen ID.4
Practicality
BYD Sealion 7 practicality score: 5/5
Volkswagen ID.4 practicality score: 4/5
If carrying capacity is your number one priority, the BYD Sealion 7 makes a strong case for itself. It boasts a large boot and a spacious cabin with plenty of room for passengers in both the front and back. The flat floor, a common benefit of purpose-built EVs, means the middle-seat passenger in the rear gets a good amount of legroom. There's also a useful storage area under the bonnet – or 'frunk' – for stowing charging cables.
The Volkswagen ID.4 is by no means impractical. It’s a roomy family car with a boot that will swallow luggage or a big weekly shop with ease. Passenger space is also generous, and there are plenty of cubbies and storage spots dotted around the cabin. However, it can’t quite match the outright boot volume of the BYD and it misses out on the handy frunk, giving the Sealion 7 a clear win in this category.
Driving Impressions
BYD Sealion 7 driving score: 3/5
Volkswagen ID.4 driving score: 4/5
This is where the established experience of Volkswagen comes to the fore. The ID.4 is a relaxing and easy car to drive. The suspension is set up for comfort, doing a good job of absorbing bumps and potholes, particularly at higher speeds. It feels secure and composed on the motorway, and the light steering makes it easy to manoeuvre around town. It’s not a thrilling car to drive, but it is competent and reassuring.
The BYD Sealion 7 also prioritises a comfortable ride, and it's quiet and smooth in most situations. The performance from the electric motor is brisk, as you'd expect. However, it doesn't feel as polished or settled as the ID.4 on undulating British B-roads. The steering can feel a little vague, and it lacks the all-round composure of its German rival. It’s perfectly adequate for the daily grind, but the ID.4 offers a more sophisticated driving experience.
Technology and Equipment

Volkswagen ID.4 technology and equipment score: 3/5
Both cars adopt a minimalist, screen-focused approach to their interiors. The Sealion 7 is dominated by BYD's signature rotating central touchscreen, which is large and packed with features. You also get a smaller digital display for the driver and a good level of standard equipment. However, like many modern cars, burying key controls within touchscreen menus can be distracting on the move.
It’s a similar story in the Volkswagen ID.4. A large central infotainment screen handles most functions, complemented by a small driver’s display attached to the steering column. While the system itself works reasonably well, VW's use of touch-sensitive sliders for volume and temperature control is fiddly to use compared to physical buttons. Both cars come with Apple CarPlay and Android Auto, and a good suite of safety assists, so it’s a level playing field in the tech department.
Running Costs
BYD Sealion 7 running costs score: 3/5
Volkswagen ID.4 running costs score: 4/5
As pure electric cars, both the Sealion 7 and the ID.4 benefit from zero road tax and are exempt from congestion charges. Charging at home will also be significantly cheaper than filling a petrol or diesel car with fuel. The ID.4 scores well here thanks to its efficient powertrains and a wide choice of battery sizes, allowing buyers to pick a model that best suits their budget and range requirements. VW's large dealer network is also a plus.
The BYD Sealion 7 is competitively priced and features the company’s well-regarded 'Blade Battery' technology, which comes with a strong warranty. However, as a newer brand in the UK, questions remain over long-term residual values, and insurance costs may be higher than for an established model like the ID.4. For overall peace of mind and potentially lower whole-life costs, the Volkswagen has the edge.

The BYD Sealion 7 is an impressive new entry into the electric SUV class, offering standout practicality and bold styling. It proves that new brands can quickly get up to speed and challenge the establishment.

It’s a more polished and sophisticated car to drive, its running costs are more predictable, and it comes with the reassurance of a brand that UK buyers know and trust.
If you need the absolute maximum amount of space, the Sealion 7 is certainly worth a look. But for most buyers, the ID.4 is the better all-round package. It’s a comfortable, competent, and sensible electric family car that is easy to recommend.
