Used BYD Sealion 5 for Sale

A used BYD Sealion 5 DM-i puts BYD's Super Hybrid with DM-i technology within reach at a considerable saving against new. For a plug-in hybrid, that saving works differently to a pure electric SUV. Running costs stay low no matter who owned the car first, thanks to a drivetrain designed around efficiency rather than battery size alone.

Both trims measure 4,738mm long with a 2,712mm wheelbase, proportions that translate into a genuinely spacious five-seat cabin and a 463-litre boot. New, the Sealion 5 DM-i already undercuts many combustion SUV rivals on running costs. Used, that value case only strengthens.

Why Buy a Used BYD Sealion 5?

Running costs are where a used BYD Sealion 5 pulls ahead of combustion rivals in its class. Comfort models cover up to 38.5 miles on electric-only driving alone (WLTP combined), while Design extends that to 53.4 miles, enough for most daily commutes on a single home charge. When a longer trip calls for it, the Xiaoyun petrol engine takes over, extending the combined range to as much as 631 miles on a full charge and a full tank.

Standard equipment carries through the whole range, whatever the age of the car. Every Sealion 5 DM-i comes with a touchscreen display, vegan leather seats, adaptive cruise control and Vehicle-to-Load technology as standard, across both trims.

BYD extended the Blade Battery warranty to 8 years or 250,000km (approximately 155,300 miles) in January 2026, with a guaranteed minimum State of Health of 70 per cent. That cover applies retroactively to all BYD UK models already on the road, so a used buyer picking up a two or three-year-old Sealion 5 benefits in full, backed by Vertu's own preparation and checks before the car reaches the forecourt.

Who Is the Used BYD Sealion 5 Best For?

Four types of buyer get the most from a used Sealion 5 DM-i, each drawn to a different strength of the DM-i system.

Used BYD Sealion 5 Trims and Specifications

The used market carries both Sealion 5 DM-i trims: Comfort and Design. Unlike some BYD models where certain trims have already been discontinued, both remain part of the current BYD UK range, so used car buyers are choosing between the same two specifications available new.

Comfort forms the well-equipped entry point, with a 12.8-inch touchscreen, adaptive cruise control, lane keep assistance and rear parking sensors all standard. Design builds on that with additional convenience: a 360-degree camera, wireless smartphone charging, heated front seats and an electric tailgate.

When comparing used examples, the clearest difference between the two trims is the equipment fitted rather than the age of the car, since both have used the same specification since launch. The table below sets out what's standard on each.

Used BYD Sealion 5 Engines and Performance

The Sealion 5 DM-i's Super Hybrid system is built around fewer complications than a conventional self-charging hybrid. Rather than switching between two separate power sources at speed, the DM-i technology system runs primarily as an EV, with the 1.5-litre Xiaoyun petrol engine acting mainly as a generator to keep the Blade Battery topped up. That's a simpler day-to-day relationship between engine and motor than many combustion-hybrid rivals manage, and the Xiaoyun engine's thermal efficiency of 43.06 per cent means it burns less fuel doing that work, regardless of how the car has been driven before.

The Blade Battery itself uses lithium iron phosphate (LFP) chemistry, a cell format known for stable, gradual degradation rather than a sharp drop-off in capacity. That matters for a used buyer weighing up a Sealion 5 DM-i against an older combustion SUV or a rival hybrid car, since it's the kind of component that keeps performing consistently over time rather than needing early replacement.

Comfort delivers 0-62mph in 7.7 seconds; Design, with its larger battery, reaches the same benchmark in 8.1 seconds. Both share the same 212 PS system output and 106mph top speed. The table below sets out the full picture.

What Is It Like to Own a Used BYD Sealion 5?

Life with a Sealion 5 DM-i settles into a simple daily pattern. Plug in overnight at home, and most owners start each day with a full electric range, whether that's 38.5 miles in Comfort or 53.4 miles in Design.

When the battery runs low, or a longer motorway trip is on the cards, the Xiaoyun engine takes over automatically, extending the total range to as much as 631 miles on a full charge and tank. The transition needs no input from the driver.

Servicing stays straightforward. With a Permanent Magnet Synchronous motor handling most day-to-day driving, the drivetrain carries less mechanical strain than a conventional petrol SUV covering the same mileage. OTA updates delivered through the BYD app let the car's software improve after purchase, without a trip to the dealership for every change.

Practicality doesn't change with age or mileage. The boot handles everything from a family shop to a full set of luggage, just as it did on day one, with the same 40:60 split rear seats available to extend it further when needed.
