Why BYD Sealion 7 stands out
The blend of modern styling and thoughtful packaging is apparent from the moment you slide into the cabin. BYD hasn’t just built an electric SUV; they’ve tried to deliver a holistic experience where interior comfort, space, and driving dynamics align harmoniously. With buyers increasingly gravitating toward electric SUVs, finding one that actually delivers on all fronts in terms of comfort, space, and real-world usability can be rare. Sealion 7 aims to fill exactly that gap.
Inside the cabin—comfort and quality
Open the doors and you’re greeted with a cabin that feels both modern and inviting. The BYD Sealion 7 interior offers dual-tone cabin themes in Black or Tahiti Blue with Nappa-leather upholstery, lending a premium feel without going overboard. The dashboard has a minimalist charm to it: a big 15.6-inch rotating touchscreen infotainment panel sits flush in a glossy black trim, matched with a digital 10.25-inch driver’s display showing all vital driving info clearly.
The steering wheel is a comfortable four-spoke unit with mounted controls for audio and calls. The center console offers generous storage under a wide armrest, plus cup holders and easy-to-reach controls. Visitors and owners alike often comment on how intuitive everything feels—even first-time EV drivers find the interface friendly and easy.
The back seats get some love, too: dual-zone climate control, rear AC vents, and even heated rear seats in most configurations make sure everyone onboard is comfortable. A panoramic glass roof adds to the sense of space, letting natural light in and enhancing ambiance.
For the audiophile and technology enthusiast, there’s a high-end 12-speaker Dynaudio system, ambient lighting, wireless Apple CarPlay and Android Auto, and even more modern touches like a head-up display and V2L functionality for powering small devices—a neat feature for trips or impromptu outdoor use.
Size and dimensions—roominess that impresses
The Sealion 7 is a big-volume car: the dimensions are an unmistakable sign of comfort inside. According to official figures, its length is 4,830 mm, width is 1,925 mm, height reaches 1,620 mm, and wheelbase is 2,930 mm. With such a footprint, it could bestow its majesty on the road while giving enough interior room for legroom, shoulder space, and headroom for all five passengers.
Given its size, Sealion 7 remains reasonably maneuverable. The turning radius of about 5.85 m helps in city driving and parking. For a mid-size SUV, the balance between cabin space and manageable external dimensions is a strong point.
Quick look—Key Dimensions
| Measurement | Value |
| Length | 4,830 mm |
| Width | 1,925 mm |
| Height | 1,620 mm |
| Wheelbase | 2,930 mm |
| Rear trunk (seats up) | ~500 L |
| Front trunk (frunk) | ~58 L |
Because of these measurements, passengers rarely feel cramped. Whether a tall driver in front or two adults on the back seat, Sealion 7 accommodates comfortably—a crucial factor when you consider using it for long drives or family trips.
Performance and driving dynamics
Under the hood—or rather, “under the floor”—Sealion 7 makes good use of advanced EV tech. It’s offered with an 82.56 kWh “Blade” battery—a strong foundation for decent range and performance. Two main variants exist: a rear-wheel-drive single-motor “Premium” version and an all-wheel-drive dual-motor “Performance” version.
The Premium (RWD) version delivers around 313 PS (about 230 kW) with 380 Nm torque and claims a WLTP/NEDC-type range of up to 567 km. It does 0–100 km/h in about 6.7 seconds—sprightly enough for everyday driving.
If you need instant punch, the Performance AWD ups the ante: its dual motors combine for approximately 530 PS, about 390 kW, and a substantial 690 Nm torque. That equates to a 0-100 km/h sprint in a little over 4.5 seconds, which is pretty impressive for an electric SUV of this mass.
Such performance ensures that the Sealion 7 doesn’t feel sluggish even when fully loaded or driving through traffic. The AWD version feels especially stable and confident on highways or winding roads. Many owners on forums report smooth acceleration, quiet cruising, and a comfortable ride—despite the SUV’s relatively heavy curb weight of over 2.2 tonnes.
Real range tends to be lower than the actual claim. Some owner-shared feedback puts practical range in mixed city/highway driving at around 400-420 km, while that further drops when driving fast on the highways. Still, even with that, convenience in home charging or regular top-ups will keep Sealion 7 reasonably viable without “range anxiety” as a daily driver for many owners.
Pros and cons—a balanced look
| Advantages/Benefits | Things to consider / Limitations |
| Spacious cabin with quality upholstery and good build. | Heavier weight—may feel less nimble than smaller EVs. |
| Large infotainment screen, premium audio, modern tech, and comfort features. | True real-world range is lower than claimed. |
| Versatile storage: plenty of boot space + front trunk. | Charging infrastructure is required for full potential. |
| Strong performance, especially the AWD version. | A larger size can make tight city parking a bit tricky. |
| Comfortable ride quality for a large EV SUV. | Maintenance and servicing may be costlier (EV components, tires, etc.). |
This frank comparison shows that while the BYD Sealion 7 interior, dimension, and performance combo makes it a compelling package, you should consider how and where you’ll use it—city commuting, long trips, family use, or weekend drives—to judge whether it fits your lifestyle.
Who is Sealion 7 for—and who might prefer something else
Those who need a spacious, modern electric SUV with plenty of features for daily commuting and the occasional long drive will find it difficult to look past the Sealion 7. It would appeal to families, couples who like comfort and gadgets, or even people shifting to an EV for the long haul.
On the other hand, if your driving is mostly within tight city spaces, with frequent stops, or you have charging limitations, then a smaller EV may make more sense. The curb weight and size may add some extra overhead in terms of maneuvering, and you might not fully exploit the power and range benefits.
