Choosing a family car used to be simple. You picked the estate that could fit the dog and the weekly shop, and off you went. But these days, with the electric revolution in full swing, the choice is overwhelming. If you’ve been scrolling through listings looking for something that stands out from the crowd but still handles the school run with ease, you might have stumbled across the BYD Sealion 7.
It’s a bit of a head-turner, isn’t it? With sleek lines that look more like a sports car than a practical hauler, it’s designed for those who want to drive something different. But looks aren't everything. We know you need to know if it can actually handle real life—from muddy football boots to long motorway slogs. Let’s take a look at what this electric SUV has to offer.
The BYD Sealion 7 sits in a fascinating spot in the market. It’s what the industry calls a "coupe-SUV." essentially meaning you get the high driving position and chunky wheels of an SUV, but with a sloping roofline that looks much sportier. It’s built to be comfortable, spacious, and packed with enough tech to keep the kids entertained (or distracted) on long journeys.
BYD might be a newer name to some, but they are giants in the battery world. The Sealion 7 is their answer to the incredibly popular Tesla Model Y. It’s pitched as a slightly more premium, design-focused alternative. If you find the minimalism of a Tesla a bit too stark, or the price of a German rival a bit too steep, the Sealion 7 tries to offer a "best of both worlds" solution. It’s aiming for that sweet spot where luxury meets family practicality.
Let’s talk about the big one: range anxiety. It’s the thing that keeps prospective EV buyers up at night. The BYD Sealion 7 range is impressive on paper, offering figures that suggest you can handle long road trips without a constant eye on the battery gauge.
However, like all EVs, motorway driving at speed will eat into that range faster than city driving. The car uses BYD’s "Blade Battery" technology, which is designed to be safer and more durable than older battery types. While it’s heavy, which can impact how nimble the car feels in corners, the trade-off is a solid, planted feel on the road.
When you do need to plug in, the Sealion 7 is ready. The higher-spec models support rapid charging up to 230kW. In plain English? If you find a fast enough public charger, you can top up the battery from 10% to 80% in roughly the time it takes to grab a coffee and a sandwich. For home charging, it takes the standard AC speeds, meaning an overnight plug-in will have you ready for a full day of driving by morning.
One of the biggest selling points here is value. The BYD Sealion 7 price generally undercuts many of its premium rivals. You get a lot of car for your money. Even the entry-level models come generously equipped, so you aren't forced to spend thousands on optional extras just to get heated seats or decent navigation.
Because BYD is aggressive about getting cars on driveways, financing options can be quite competitive. When looking at used models, the depreciation curve (how much value the car loses over time) often works in your favour as a second-hand buyer. You can often pick up a nearly-new example with low mileage for a significant saving compared to the list price of a brand-new one.
Step inside, and you’ll see where the effort went. The BYD Sealion 7 interior feels plush. We’re talking soft-touch materials, quilted seats on higher trims, and a sense of luxury that feels a step above some plastic-heavy competitors. The floor is flat, which is great news for whoever gets stuck in the middle back seat—no more fighting for foot room.
The centrepiece of the cabin is the massive rotating screen—a BYD signature trick. You can have it portrait for sat-nav or landscape for watching movies while you charge. It’s responsive and bright. You also get voice control that actually works fairly well, plus wireless phone charging to keep the cable clutter to a minimum.
Safety is non-negotiable for family cars. BYD has a strong track record with Euro NCAP safety testing, often scoring full five-star ratings across their range thanks to robust construction and a suite of active safety tech. The Sealion 7 comes with plenty of driver aids, like lane-keeping assist and emergency braking, to act as an extra pair of eyes on the road.
Buying used doesn't mean buying without a safety net. BYD offers a generous warranty package on new cars (typically 6 years generally and 8 years on the battery). The great news is this transfers to the new owner. So, if you buy a two-year-old Sealion 7, you’ve still got plenty of manufacturer cover left for peace of mind.
The cabin is dominated by a 15.6-inch rotatable touchscreen that handles navigation, media, and vehicle settings. You also get a digital driver display, wireless smartphone charging, and on top-spec models, a head-up display that projects speed and directions onto the windscreen. It’s a very digital-forward environment.
The Blade Battery is integrated into the car's structure (Cell-to-Body technology). This improves safety and stiffness but adds weight. The result is a smooth, stable ride rather than a sporty one. The tech allows for decent efficiency, but real-world range will drop in colder weather or during sustained high-speed driving.
Despite the number in the name, the BYD Sealion 7 is strictly a 5-seater. The "7" refers to its positioning in the BYD lineup, not its seat count. If you desperately need seven seats for a growing brood, you might need to look at a larger SUV or MPV.
No, the Sealion 7 is a fully electric vehicle (BEV). There is no petrol or diesel engine backup. It relies entirely on its battery pack and electric motors, meaning zero tailpipe emissions and access to green zones in cities.
If you are using a high-power DC public rapid charger (like the ones at motorway services), the Sealion 7 can charge from 10% to 80% in around 24 to 26 minutes, depending on the battery size and weather conditions. Charging at home on a standard 7kW wall box will take roughly 11 hours for a full charge—perfect for overnight top-ups.
