The launch of the plug-in hybrid family SUV introduces advanced powertrain technology designed for real-world flexibility. For buyers evaluating this front-wheel-drive five-seat vehicle, understanding the BYD SEALION 5 DM i electric range, battery options, and overall efficiency is a key part of the purchasing decision. This guide details the complete performance specifications across both available trim levels.
BYD SEALION 5 DM i battery size and charging specifications
The vehicle is offered with two different battery capacities depending on the chosen trim. The entry-level Comfort trim features a BYD SEALION 5 DM i battery size of 12.96 kWh. The higher-specification Design trim uses a larger 18.3 kWh battery. Both trims utilise BYD’s Blade LFP battery technology.
Both the Comfort and Design models support alternating current (AC) charging at a rate of 3.3 kW. This allows the battery to be charged from 15 percent to 100 percent in 4.5 hours. There is no direct current (DC) charging capability listed for either trim. Additionally, both models feature a 3.3 kW Vehicle-to-Load (V2L) system, which enables the vehicle to power external electrical devices directly from the high-voltage battery.
| Specification | Comfort Trim | Design Trim |
|---|---|---|
| Battery Size | 12.96 kWh | 18.3 kWh |
| WLTP Electric Range | 38.5 miles | 53.0 miles |
| WLTP Combined Range | 616 miles | 631 miles |
| AC Charging Rate | 3.3 kW | 3.3 kW |
| Charge Time (15-100%) | 4.5 hours | 4.5 hours |
BYD SEALION 5 DM i electric range performance
The official BYD SEALION 5 DM i electric range depends on the selected battery size. The Comfort trim, equipped with the 12.96 kWh battery, achieves a WLTP pure-electric range of 38.5 miles. The Design trim, featuring the larger 18.3 kWh battery, provides an extended WLTP pure-electric range of up to 53 miles. When combining the electric and combustion powertrains, the total WLTP combined range is 616 miles for the Comfort trim and 631 miles for the Design trim.
BYD SEALION 5 DM i fuel economy and hybrid efficiency
The BYD SEALION 5 DM i fuel economy figures reflect the efficiency of the Super Hybrid DM-i system. Both trims are powered by a 1.5-litre Xiaoyun engine that produces 96 PS at 6,000 rpm and 122 Nm of torque, which boasts a high thermal efficiency of 43.06 percent. This internal combustion engine works in tandem with a permanent magnet synchronous electric motor producing 197 PS and 300 Nm of torque, resulting in a combined system output of 212 PS. The vehicle is equipped with a 52-litre fuel tank.
The Comfort trim achieves a weighted combined fuel economy of 104.6 mpg and a standard combined fuel economy of 51.4 mpg. Its carbon dioxide (CO2) emissions are rated at 62 g/km. The Design trim, thanks to its larger battery capacity allowing more electric running, achieves an improved weighted combined fuel economy of 134.5 mpg, while the standard combined fuel economy remains at 51.4 mpg. Its CO2 emissions are correspondingly lower at 48 g/km. Both versions share a top speed of 106 mph, with the Comfort completing the zero to 62 mph sprint in 7.7 seconds, while the slightly heavier Design trim takes 8.1 seconds.
Trim levels, weight, and pricing
The differing battery sizes also affect the vehicle’s weight. The kerb weight for the Comfort trim is 1,724 kg, while the Design trim weighs 1,749 kg. The gross vehicle weight for the Design model is 2,195 kilograms.
Pricing starts from £29,995 on the road for the Comfort trim, and £32,995 on the road for the Design trim. Prices are indicative — confirm current price, offers and delivery times with your local BYD dealer. The Comfort trim includes eighteen-inch bi-colour alloy wheels, an eight-point-eight-inch digital instrument panel, a twelve-point-eight-inch rotatable touchscreen, and rear parking sensors. The Design trim adds front parking sensors, a three-hundred-and-sixty-degree camera, an electric tailgate, heated front seats, and a fifteen-watt wireless phone charger.
Design, space, and safety features
While efficiency is a primary focus, the vehicle also provides substantial space. The exterior dimensions measure 4,738 millimetres in length, 1,860 millimetres in width, and 1,710 millimetres in height. It features a wheelbase of 2,712 millimetres and a turning radius of 6.0 metres. The boot capacity provides 463 litres of space with the seats up, expanding to 1,410 litres when the forty-sixty split rear seats are folded flat.
The exterior features a contrast-colour D-pillar, a textured front grille, and full LED lights. Atlantis Blue is the standard paint colour, with Obsidian Black, Time Grey, and Polar White available as optional extras for £850. Safety is supported by seven airbags and a comprehensive suite of Advanced Driver Assistance Systems (ADAS), including Adaptive Cruise Control, Lane Keep Assist, and Autonomous Emergency Braking. A standard vehicle warranty of six years or 93,750 miles provides additional reassurance for owners.
