A quiet evolution sees the BYD Seal gain more kit, more practicality and more polish for 2026, showing how far the Chinese brand’s ambitions now stretch, writes James Stinson.
The BYD Seal has only been on UK roads since 2023, but the brand clearly isn’t standing still. For 2026, the sleek electric saloon gains a series of subtle yet useful upgrades aimed at sharpening its appeal without inflating its price.
New 19-inch wheels give the Seal a slightly more assertive presence, while the paint palette expands with three fresh shades—Ruby Red, Obsidian Black and Lavender Grey—joining the existing whites and greys. At the rear, the BYD badge now sits proudly above the full-width light bar, providing a cleaner and more contemporary look.
SIMPLIFIED INTERIOR
Inside, the theme is quiet refinement. The soft Nappa leather seats remain, but the headrests lose the previous stitched logo for a more minimalist feel. Even the centre armrest has been decluttered, with the NFC (Near Field Communication) badge removed (though the feature itself is still present). The changes are small but contribute to a tidier, more premium cabin.
Perhaps the most meaningful upgrade is practicality. The powered tailgate opens to reveal a significantly enlarged 485-litre boot – up from 400 litres – with new tethering hooks to keep bags in check. Up front, the Seal’s frunk has been re-engineered to offer 72 litres of storage, enough for charging cables or even a carry-on suitcase.
TECH UPGRADE LEADS THE CHARGE
BYD already packed the Seal with generous technology, but the 2026 model ups the ante. A new Driver Monitoring System keeps an eye on the driver’s attention, bringing the car in line with the latest safety standards. There’s also a new Bluetooth key system, allowing owners to unlock and start the car via smartphone.
The core infotainment and comfort systems remain impressive. A huge 15.6-inch rotating touchscreen, panoramic glass roof, twin wireless charging pads and a 12-speaker Dynaudio sound system are all standard on Design models. Excellence trim adds a crisp head-up display and additional convenience tech.
PERFORMANCE: FAST OR FASTER
Performance is another area where the Seal continues to punch above its weight. The base Design model uses a single rear-mounted motor delivering 308bhp, enough for 0–62mph in 5.9 seconds. For most drivers, that’s more than brisk enough.
Those wanting something closer to sports-saloon territory can look to the Excellence model. Its dual-motor all-wheel-drive setup unleashes 523bhp and a hefty 670Nm of torque, firing the car to 62mph in just 3.8 seconds. Semi-adaptive dampers give it an added layer of composure, adjusting responses depending on road conditions. Both versions top out at 112mph.
RANGE AND CHARGING
Range remains a Seal strength thanks to BYD’s cobalt-free Blade Battery. The 82.5kWh pack provides 354 miles in Design trim and 323 miles in Excellence guise (WLTP figures). A peak DC charging speed of 150kW means a 10–80% top-up takes around 37 minutes, putting it broadly in line with rivals at this price point.
PRICE AND WARRANTY
One of the most appealing aspects of the 2026 Seal is what hasn’t changed: the price. The Design starts at £45,730, while the Excellence remains at £48,730, despite the additional kit and engineering tweaks. That positions the Seal competitively against established European and Korean rivals.
As with all BYD models, the Seal is covered by a six-year / 93,750-mile warranty, and its battery carries an eight-year / 155,350-mile guarantee – reassuring for buyers still sizing up relatively new EV brands.
VERDICT
The 2026 BYD Seal isn’t a ground-up reinvention, but it didn’t need to be. Instead, BYD has focused on meaningful improvements: more storage, more safety tech, more personalisation and the same eye-catching performance figures. It’s not perfect – the styling changes are subtle and the charging speeds aren’t class-leading – but it remains one of the more compelling electric saloons in the mid-£40k bracket.
