BYD Seal facelift brings 800V electricals and tech overhaul
Roof-mounted Lidar sensor promises to improve driver assistance systems
Tesla Model 3 rival gets major update mere months after it arrived in the UK
The BYD Seal has received a significant update in its native China, bringing improved electricals, enhanced autonomous driving capabilities – but also a cut in range.
The headline change is a move from the existing car’s 400V electrical systems to an 800V system. This cuts the Seal’s 10-80% charging time from the current 37min down to 25min, suggesting its peak rate has been increased from the current cap of 150kW – although BYD has yet to confirm the new limit.
Local media has reported that the more powerful electricals also enabled the fitment of uprated adaptive dampers, which are said to improve ride comfort and body control.
The saloon can now be had with a roof-mounted Lidar sensor, claimed to bring a significant upgrade to its advanced driver assistance systems (ADAS). BYD highlighted improvements to its adaptive cruise control and automated parking systems, in particular.
Two batteries are available, measuring 61.44kWh and 80.64kWh in capacity. The latter is down on the 82.5kWh currently offered in the UK. That cuts its range (as measured by the Chinese CLTC test cycle) from 435 miles to 404 miles – a 9% reduction.
That suggests the facelifted Seal could offer a WLTP range of around 320 miles, down from the 354 miles quoted for the existing version. BYD has yet to explain why it opted for a smaller battery pack.
The powertrains are unchanged, with a choice of a lone 308bhp motor on the rear axle or a dual-motor, four-wheel drive configuration putting out a combined 523bhp.
Inside, the revised Seal gets a new steering wheel design with a flat bottom and an airbag trimmed entirely in leather. The centre console’s piano-black finish has been replaced with a matte grey plastic, and the dashboard’s prominent air vents are gone in favour of a flat panel.
Autocar has asked BYD UK when the new Seal will arrive in showrooms. It is already available in China, hours after its unveiling.
