Deliveries of the BYD SEAL, an all-electric D-segment four-door, five-seater sports saloon, will start in the UK in November 2023, with two models, ‘Design’ and ‘Excellence-AWD’.
The ‘Design’ single-motor version with rear-wheel drive has a power output of 230 kW (313 PS) and accelerates from 0-62 mph in 5.9 seconds. The 82.5 kWh battery gives a range of 353 miles.
The BYD SEAL Excellence-AWD has an electric motor on the front and rear axles (160 kW + 230 kW) giving all-wheel drive and a power output of 390 kW (530 PS), resulting in a rapid 0-62 mph acceleration time of 3.8 seconds. The Excellence-AWD model has a range of 322 miles from the same 82.5 kWh battery as the ‘Design’ version.
The SEAL range will start from £44,990 for the Design-RWD and £47,990 for the Excellence-AWD.
The BYD SEAL can be rapid charged at up to 150 kW DC, allowing a 30% to 80% charge in 26 minutes. It will also have 11 kW 3-phase AC charging capacity as standard.
Like all BYD passenger cars offered in Europe, the BYD SEAL features a Blade Battery, developed in-house by BYD. The battery pack consists of 172 thin cells that resemble blades. The Blade Battery uses lithium iron phosphate (LFP) as a cathode material, which offers a higher level of safety and durability compared with conventional lithium-ion batteries.
LFP batteries are 100% free of cobalt, a material that raises ethical and environmental concerns in the mining industry. LFP batteries are also more resistant to extreme temperatures. They have better thermal stability and are less sensitive to temperature fluctuations, while they can withstand more charge and discharge cycles with hardly any loss of capacity, making the batteries particularly durable. With a height of only 110 mm for the entire battery pack, the Blade Battery also improves vehicle packaging and optimises the interior space of the BYD SEAL.
The Blade Battery has exceeded the requirements of the Nail Penetration Test, the most rigorous method to test battery thermal runaway, simulating the consequences of a serious road accident.
The BYD SEAL comes with a high-efficiency heat pump system as standard. This allows for efficient regulation of the battery temperature via direct cooling and heating of the refrigerant, as well as control of the passenger compartment temperature with low energy consumption. The heat pump can also absorb waste heat from the electric powertrain, while it can withstand temperatures ranging from minus 30°C to 60°C.
BYD’s battery technology also supports V2L (Vehicle-to-Load), allowing the BYD SEAL to be used as a portable power supply for electrical devices.
Like the BYD ATTO 3 and the recently launched BYD DOLPHIN, the new BYD SEAL is based on BYD’s e-Platform 3.0, which is designed exclusively for pure-electric vehicles. The BYD SEAL is the first vehicle to implement BYD’s Cell-to-Body (CTB) technology which means the battery is incorporated within the vehicle structure, integrating the battery pack’s top cover with the traditional body floor. This forms a structure incorporating the top cover, the Blade Battery and the tray, improving rigidity and space utilisation.
The SEAL has a boot capacity of 400 litres and an additional 53-litre ‘frunk’ under the bonnet (for the rear-wheel drive version).
The first dealer deliveries of the BYD SEAL will be in Q4 2023, with customer deliveries from November.
BYD claims that it’s the world’s leading manufacturer of ‘new energy vehicles’ (NEVs), which means BEVs and PHEVs, and that it’s the fastest growing automaker worldwide.
