Summary
- The BYD Sealion 7 is the brand’s most expensive model yet.
- It has a roomy interior packed with technology.
- Performance-based models lack excitement compared to rivals.
The world of cars is moving at a lightning-fast pace, with manufacturers adopting a greener way of life. Demand for electric vehicles is growing, especially for used examples, since EVs depreciate rapidly. However, the BYD Sealion 7 is the brand’s most expensive vehicle yet. Is there any need for a performance-based electric SUV, or is BYD getting too big for its boots?
The truth is, China-made EVs are leading the way, and BYD is one of China’s largest privately-owned manufacturers specializing in batteries. Before venturing into EVs, BYD developed batteries for everyday items, including mobile phones, industrial machines, and forklifts. It’s not surprising that the company makes excellent electric vehicles, too.
I’ve tested the entire range of BYD vehicles available in the UK, and each provides a luxurious feel at a reasonable price. Other markets get more BYD models, including Han L and Tang L. That said, the all-new BYD Sealion 7 has a hefty price tag that pulls its overall performance into question.

2025 BYD Sealion 7
The BYD Sealion 7 is an electric SUV coupe with up to 523 bhp on tap. It uses the fastest mass-produced e-motor that can run at speeds up to 23,000 rpm, but fails to impress compared to other performance-based SUVs. The Sealion 7 is packed with a plethora of technology as standard, leaving little need to upgrade to more expensive trims available.

Price, availability, and specs
Every BYD Sealion 7 gets a heat pump as standard, to help preserve the driving range in cold weather. They also have a vehicle-to-load function for powering other electronics via a cable in the charge port. While BYD used it to bring a ‘dream city’ to life at the UK launch event in Milton Keynes, it will be useful for camping trips in the real world. There’s an impressive list of standard equipment, too:
Sealion 7 standard key features
- Heat Pump
- Heated seats throughout with ventilated front seats
- Privacy glass
- Rotating touchscreen
- Wireless smartphone charging
The current line-up in the UK has two battery options available. An 82.5 kWh battery in Design models delivers 523 bhp and up to 283 miles of range from a single charge. A bigger 91.3 kWh battery for Excellence grades has the same output, but extends the range to 312 miles. A more accessible Comfort will be available soon, sharing the 82.5 kWh battery but with less power and almost as much range as the biggest option. Regardless of battery size, every Sealion 7 is limited to a top speed of 133 mph.

5 China-made EVs blow the US competition away
These EVs from China are wiping the floor with global leaders. It’s a shame we won’t see them in the US.
What I liked about the BYD Sealion 7
Roomy interior and packed with clever technology
Like the rest of the range, there’s a clear focus on technology. Crisp digital displays line the dashboard. A large 15.6-inch touchscreen display acts as a command center, but not to the extreme of Tesla. You can rotate it between portrait and landscape orientation — a signature of BYD screens, which I found useful for viewing the route ahead while using the built-in navigation — and a 10.25-inch digital instrument cluster.
There are still physical buttons for important functions, and voice commands for everything you need. I tested opening the windows, adjusting the cabin temperature and asking for route guidance. Where most voice-activated systems would struggle to understand my strong Scottish accent, the BYD understood every prompt the first time.

5 things you might not know about driving an EV in cold, snowy weather
It’s perfectly fine to own in EV in places where you can go sledding or skiing.
Another clever function that more cars require is ventilation in the wireless charging cradle. Again, BYD continues to challenge competitors with a 50-watt wireless charging pad. If you’ve ever used this feature in a car, especially when using Apple CarPlay or Android Auto, the phone gets hot. Having an air vent allows cool air to circulate between the phone and cradle, preventing overheating. It’s simple, but effective.
On to practicalities, the roomy cabin has ample space throughout. Three adults can easily fit in the rear, and the slightly reclined backs stay comfortable on long journeys. Though it’s a coupe, the sloping roof begins behind rear passengers, so it doesn’t impact headroom. Plus, it received the maximum five-star safety rating from Euro NCAP.

Do you prefer CarPlay, Android Auto, or bespoke in-car infotainment
There was a time when I loved Apple CarPlay and Android Auto, but the issues I have encountered with my Ioniq 5’s USB port, leading to both platforms constantly disconnecting (I pretty much don’t use either anymore), have led me to change my opinion. I’ve talked to both Hyundai and Apple, and both companies blame the issue on each other.
What I didn’t like about the BYD Sealion 7
When does the performance kick in?
I struggled to find faults with the Sealion 7. It has plenty of storage space, but the sloping roof eats into the rear of the car, and the wide cupholders don’t grip slim bottles of water. My biggest gripe was the power of the performance model.
It’s quick in a straight line, but I didn’t get the same sense of excitement as a Kia EV6 GT.
Despite having a 91.3 kWh battery available, its sole purpose is to add a few extra miles of range over the 82.5 kWh (and add Nappa leather seats). Though BYD brags about having the world’s fastest electric motor in mass-production at 23,000 rpm, it doesn’t translate to fun. Sure, for an SUV of this size to launch from 0-62 mph in less than five seconds is impressive, but you can feel its body roll on bends at higher speeds, and there’s little feedback from the steering wheel. It’s quick in a straight line, but I didn’t get the same sense of excitement as a Kia EV6 GT.

Should you install a home charger for your EV, or use charging stations instead?
It’s always tempting to install an at-home charger, but you shouldn’t do it automatically.
Should you buy the BYD Sealion 7?
The BYD Sealion 7 is a fast SUV with lots of tech as standard
Even though I was slightly disappointed in the performance-based model, I can’t deny that the Sealion 7 is an excellent choice for families looking for an electric vehicle without having to pay extra for basic features. It’s efficient, safe, spacious, and packed with entertainment to keep the kids occupied.
My choice would be the Sealion 7 Design, since you get all the power of the Excellence model without the premium price tag. However, if you don’t want to worry less about making your EV range last longer, then the Comfort trim will save you a bundle of cash and get close to the maximum claimed range in the lineup.
