Thanks to the flagship BYD Sealion 7’s twin-motor setup, the Chinese new-energy-vehicle brand’s battery-electric crossover packs an almighty wallop!
We like: Blistering performance, tech-swathed interior, spaciousness.
We don’t like: Pricey, so-so handling, tries to be a jack of all trades, but masters none.

Where does the BYD Sealion 7 fit in?
The BYD Sealion 7 is a performance-oriented all-electric crossover (family car). It is available in single-motor Premium and twin-motor Performance All-Wheel Drive (AWD), with the latter under review here.
The BYD Sealion 7’s coupe-SUV-like design, penned by Wolfgang Egger (of Alfa Romeo 8C fame), is distinctly Eurocentric – its proportions are not unlike those of models such as the BMW X4, Kia EV6 and Haval H6 GT. It’s a pity our test unit’s colour didn’t show off the design elements in great detail.
Pricing starts at just over R1 million, but picking rivals for the BYD Sealion 7 is tricky because it’s larger than similarly priced models. Compared with the BYD (390 kW; 456-542 km), the BMW iX1 xDrive30 M Sport (225 kW; 417-440 km) and Mercedes-Benz EQB350 4Matic Progressive (215 kW; 395-423 km) have notably lower outputs (and therefore, offer less performance), as well as reduced claimed ranges.
The BYD Sealion 7 Performance AWD‘s closest competitor is arguably the Volvo XC40 Recharge Twin Motor Ultimate (300 kW, 478 km) with its stated 4.8-sec 0-100 kph time, but like the BMW and Benz, it’s a compact premium crossover, as opposed to the BYD, which is family car, like the outgoing BMW iX3.

How the BYD Sealion 7 fares in terms of…
Efficiency and Performance
With an electric motor powering each axle and peak outputs of 390 kW and 690 Nm, the BYD Sealion 7 Performance AWD‘s straight-line performance is bound to be plentiful. And, don’t confuse the “4.5S” badge on the BYD’s tailgate with nomenclature; that is, in fact, the variant’s claimed 0-100 kph time.
So does it do what it says on the, um, tailgate? Oh, yes. Our test gear confirmed the BYD romped from a standstill to 100 kph in 4.45 sec. Thanks to its dual-motor setup, there’s no hesitation or loss of traction; no matter which drive mode you’ve engaged, the BYD simply bolts off and hurtles towards the horizon.
Speaking of drive modes, the BYD has a refreshingly simple and uncomplicated setup with Eco, Normal, Sport, and Snow. It’s a cinch to switch between modes, each of which comes with its own display theme.
Although South Africa’s public-charger network is expanding and most BYD Sealion 7 buyers are likely to install a wallbox at their homes anyway, range anxiety remains synonymous with the prospect of electric-car ownership. BYD claims a range of 456 to 542 km from a full charge, but that seems rather optimistic. Despite adopting a conservative driving style most of the time, we could only muster around 400 km.
At the end of the test unit’s tenure in our fleet, it indicated an average energy consumption figure of 18.0 kWh/100 km, compared with the Chinese brand’s claim of 21.2 kWh/100 km. But, that said, our testers couldn’t resist the temptation of exploiting the BYD’s rapid-sprinting ability once in a while, so perhaps with Eco mode engaged (and much more self-discipline), one could eke out a few more kilometres…
Under that body lies the battery, an 82.6 kWh Blade unit. Its DC fast-charging capacity is rated at 150 kW for public outlets, while its AC input (such as from a wallbox) is rated at 11 kW. By using the latter, you can replenish around 100 km of range in about 2 hours. The Sealion 7 also supports Vehicle 2 Load (V2L) of up to 3.3 kW, which means you can use it to power accessories on camping trips, for example.
Ride and Handling
In terms of dynamic ability, the Sealion 7 isn’t as sporty as it looks. We’re not sure whether it’s meant to be a higher-riding sedan or a lower-slung crossover, but regardless, given its elevated centre of gravity, the BYD’s handling skillset doesn’t quite match its straight-line performance, which is a bit of a pity.
Given its relatively soft suspension and the fact that its body tends to lean when cornering at higher speeds, the BYD’s handling is not particularly poised. However, this softer setup does contribute to a pleasantly pliant ride, with sufficient damping to absorb road imperfections like ruts and small potholes.
Also, considering its tremendous straight-line performance and kerb weight (2 340 kg), the Performance AWD’s braking action could be more reassuring. We felt the brake-pedal travel was too long.
The Sealion 7’s driving experience may have inspired more confidence had the steering felt more direct and better weighted. While we don’t want to overcriticise the lack of dynamism in a family car (medium SUV), the “Performance AWD” badge sets an expectation for a greater level of driver engagement.
While it may not tick every box for a performance-focused driver, the BYD truly excels on the daily commute. Road and wind noise are well-suppressed, and the car’s seating position provides good outward visibility, although the view out the back is somewhat compromised by the tiny rear window.
Practicality and Features
In terms of practicality, the Sealion 7 fits the family-car bill to a tee. Its load bay is said to have a 500-litre capacity, which expands to over 1 700 litres when the rear seats are folded down. There’s also a 50-litre storage compartment under the bonnet, which is a great place to put those charging and V2L cables.
Courtesy of its lengthy wheelbase – which, at 2 930 mm, is only fractionally shorter than that of a BMW X5 – the BYD Sealion 7 offers generous occupant space, including at the rear, where head- and legroom is commendable. As a result, it can seat 4 adults of average height plus 1 child quite comfortably.
The plush Nappa leather seats not only feel premium, but also have a unique visual effect, appearing light grey or pastel blue depending on the light. In terms of comfort, all seats are heated, while the front ones are also equipped with a cooling function.
Like in other BYD products we have reviewed, the front of the cabin is dominated by the huge (15.6-inch) infotainment touchscreen, which can be rotated for a landscape or portrait view. Just be mindful that in its vertical orientation, the display will be unviewable if you’re wearing polarised sunglasses.
The screen’s resolution and functionality are impressive, but its layout is a drawback. Navigating “menus within menus” is complex and takes time to get used to, but the effective voice control system provides a good solution, allowing you to easily say, “cabin temperature at 22 degrees, please”, while on the move.
We’ve already mentioned the admirable quality of the seats; similarly, the cabin generally feels plush and well-assembled at this price point, even though the wiper and indicator stalks feel a little insubstantial.
On the other hand, the Performance AWD’s list of standard equipment is anything but insubstantial. It includes wireless Apple CarPlay and Android Auto, a panoramic sunroof, a head-up display, NFC access, and a 12-speaker DynAudio audio system.
The BYD’s cabin further features a quartet of USB ports (two at the front and two at the back) and even a powerful, ventilated charging pad.
What’s more, the BYD’s safety suite is comprehensive. It includes a total of 9 airbags, ABS with EBD, and electronic stability control, as well as a 360-degree-view camera system.
The vehicle is also equipped with advanced driver-assistance systems (ADAS), offering features such as adaptive cruise control, lane-keeping assist, front-collision alert, and autonomous emergency braking.

Summary
The mighty performance, comprehensive standard-equipment list and impressive practicality of the top-of-the-range BYD Sealion 7 are undeniably impressive. Rand-for-rand, as a “from new” proposition, it outpunches smaller, premium-badged rivals. At the same time, however, the BYD is pricey relative to what is available in the used market, where “nearly new” BMW iX units, for example, are within reach.
Should you buy a BYD Sealion 7 Performance AWD? We’d answer that question with another: Do you really need a premium battery-electric crossover that produces almost 400 kW?
Sure, it’d give you bragging rights around the braai fire, but with our logical consumer hat on, we think it would be more prudent to save R200 000 and choose the “slower” single-motor Sealion 7 – okay, so you’d miss out on Nappa leather and the head-up display, but you’ll benefit from additional range.
