For drivers making the switch to a fully electric mid-size SUV, the distance the vehicle can travel on a single charge is one of the most important considerations. The BYD Sealion 7 range UK figures vary depending on which of the three trim levels you choose, as the models feature different drivetrain configurations and battery capacities.
The entry-level Comfort RWD (Rear-Wheel Drive) model achieves a combined WLTP range of 300 miles, and up to 392 miles on the WLTP city cycle. The mid-spec Design AWD (All-Wheel Drive) model, which features a dual-motor setup but the same battery as the Comfort, has a combined WLTP range of 283 miles and a city range of 373 miles. Finally, the top-spec Excellence AWD model features a larger battery, allowing it to achieve a combined WLTP range of up to 312 miles, and a city range of 383 miles.
Efficiency is also a key factor. The combined energy consumption is rated at 3.12 mi/kWh for the Comfort trim, 2.9 mi/kWh for the Design AWD, and 2.84 mi/kWh for the Excellence AWD. To help maximise these figures in colder weather, every model is fitted with a heat pump as standard. This heat pump operates in temperatures ranging from −30°C to 60°C. It increases thermal efficiency by 20% and can improve the vehicle’s range by up to 20% in cold conditions.
BYD Sealion 7 battery size
The foundation of this electric range is the brand’s proprietary power storage technology. The BYD Sealion 7 battery size depends on the trim you select, but all models utilise the Blade LFP (Lithium Iron Phosphate) battery chemistry with Cell-to-Body (CTB) construction. This structural integration provides a high torsional stiffness of 45,500 Nm/°.
The Comfort and Design AWD trims are both equipped with an 82.5 kWh capacity battery operating at 550.4 volts. For those looking for the maximum available capacity, the Excellence AWD trim is fitted with a larger 91.3 kWh battery operating at 537.6 volts.
The vehicle is also equipped with Vehicle-to-Load (V2L) technology, which allows the car’s battery to power external electrical devices up to 3.3 kW. A power strip for this system is included as standard equipment.
