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.
Want to see the Sealion 5 DM-i in action before you commit? Our byd sealion review walks through the Super Hybrid system, cabin space and everyday driving experience, giving you a clearer picture of what to expect from a used example.
The clearest reason to buy used is one that didn't exist when the Sealion 5 DM-i first went on sale. BYD extended the Blade Battery warranty in January 2026 and applied the improved cover retroactively to cars already on the road, so a used Sealion 5 DM-i benefits just as fully as a brand new one.
Every used Sealion 5 DM-i, Comfort or Design, carries the same 212 PS Super Hybrid system and full standard specification it left the factory with. At the centre of that system sits a 1.5-litre Xiaoyun petrol engine, built specifically for BYD's DM-i technology platform.
With a thermal efficiency of 43.06 per cent that doesn't change with age or a previous owner's driving style, and built on BYD's Blade Battery using lithium iron phosphate (LFP) cells, the DM-i system is engineered for durability over the long term.
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.
| Buyer Type |
Why the Sealion 5 DM-i Fits |
| Families upgrading from a smaller car |
A 2,712mm wheelbase delivers genuine rear legroom, and the 463-litre boot expands to 1,410 litres with the 40:60 split rear seats folded, enough for a weekly shop or a full set of luggage. |
| Daily commuters |
Design's 53.4-mile WLTP electric range covers most return commutes on a single overnight charge; Comfort's 38.5 miles still handles a typical local run without touching the tank. |
| Second-car households running a PHEV alongside another vehicle |
The Sealion 5 DM-i takes on short, frequent trips at a fraction of the per-mile cost of petrol alone, while keeping the reassurance of a full tank for longer journeys. |
| Buyers not yet ready for a fully electric car |
In electric-only mode, the drivetrain delivers a smooth, EV driving experience with zero tailpipe emissions whilst driving, with the petrol engine on standby the moment it's needed. |
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.

Used BYD Sealion 5 DM-i FAQs
Is the BYD Sealion 5 a Reliable Used Buy?
Yes. BYD extended the Blade Battery warranty to 8 years or 250,000km in January 2026, with a guaranteed minimum State of Health of 70 per cent, applying retroactively to cars already on the road. The Xiaoyun petrol engine's 43.06 per cent thermal efficiency keeps fuel use down regardless of how the car has been driven before. Every used BYD example is also checked and prepared by Vertu before sale, with a full mechanical inspection and video health check completed first.
How Much Does a Used BYD Sealion 5 Cost?
Used BYD Sealion 5 DM-i pricing varies by trim, age and mileage. Comfort and Design carry different starting points when new, and that gap generally carries through to the used market. Specification and car history will influence pricing too. For current pricing, visit our used BYD Sealion 5 listings or contact a Vertu colleague for a personalised quotation.
Does the BYD Sealion 5 PHEV Hold Its Value?
The BYD Sealion 5 DM-i is well placed to hold its value in the plug-in hybrid SUV segment. Strong standard equipment, an extended Blade Battery warranty covering 8 years or 250,000km with a guaranteed minimum 70 per cent State of Health, and low running costs relative to combustion SUV rivals all support residual values. Growing brand awareness across BYD's expanding UK dealer network should support used demand further still.
What Battery and Drivetrain Warranty Does a Used BYD Sealion 5 Have?
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. This cover applies retroactively to existing cars, so a used Sealion 5 DM-i benefits in full, regardless of when it was first registered or how many owners it's had. The electric drive unit carries its own 8-year, 150,000km warranty, and the vehicle warranty runs for 6 years or 93,750 miles from first registration.
Is the BYD Sealion 5 a Good Introduction to Plug-In Hybrid Ownership?
Yes. The Sealion 5 DM-i's Super Hybrid system runs mainly as an EV, delivering a smooth, electric-first driving experience with the reassurance of a petrol engine when the battery runs low. Home charging covers most daily driving, Comfort's 38.5-mile and Design's 53.4-mile electric ranges suit typical commutes, and the transition between power sources needs no input from the driver.
Which Used BYD Sealion 5 PHEV SUV Trim Should I Look For?
Comfort offers the full core specification, including a 12.8-inch touchscreen, adaptive cruise control and vegan leather upholstery, with a 38.5-mile electric range. Design adds a longer 53.4-mile electric range alongside a 360-degree camera, wireless smartphone charging, heated front seats and an electric tailgate. Buyers prioritising daily electric range and extra convenience features tend to favour Design, while Comfort suits those wanting the core experience at a lower entry point.
Can I Part-Exchange My Car for a Used BYD Sealion 5 at Vertu?
Yes. Vertu accepts part-exchange vehicles against any used car purchase, including the Sealion 5 DM-i. You can get an instant online valuation through our Sell My Car tool, or bring your vehicle to any Vertu BYD dealership for a physical appraisal. Colleagues will work your part-exchange value into your finance or purchase calculation, making the move to a used Sealion 5 DM-i straightforward.
What's the Difference Between the BYD Sealion 5 DM-i and a Fully Electric SUV?
The Sealion 5 DM-i is a BYD plug-in hybrid rather than a fully electric car. It pairs a Blade Battery and electric motor with a 1.5-litre Xiaoyun petrol engine, giving up to 53.4 miles of electric-only range before the engine extends total range to as much as 631 miles. A fully electric BYD relies solely on its battery, with no petrol backup. That makes the Sealion 5 a practical middle step for buyers who want an EV-like daily driving experience without changing their routine for longer trips.
