Is this car right for me?

Could suit you if…

  • You can plug in regularly and many journeys are short: a plug-in hybrid could suit that routine. Check this version's electric range.
  • You want practical access for everyday shopping and bags: the hatchback opening may suit your routine. Check actual boot space.
  • You would prefer less gear changing in traffic: the recorded automatic transmission may suit. Try how this exact gearbox behaves on a test drive.

Think twice if…

  • You need room for several children or extra passengers: the seat count is not recorded. Confirm this exact version's seats and child-seat fit; do not assume from the model name.
  • You cannot charge regularly: do not assume you will achieve a plug-in hybrid's advertised fuel savings.

This is general guidance about this type of car and your needs — not an inspection or approval of this individual car.

Good to know

BYD's Seal name is usually applied to an electric fastback, so a dealer listing as a plug‑in hybrid is unusual — confirm the powertrain on the VIN plate and paperwork. For a PHEV you want to check the charging equipment, electric range figures and the high‑voltage battery warranty; hybrid software and inverter servicing can be specific to the maker and may affect running costs.

Common things to check
  • Confirm powertrain on the VIN and registration documents to verify it is truly a plug‑in hybrid and not an EV/mislisted model.
  • Check charging cable(s), charging inlet operation and request a battery state‑of‑health/capacity readout to confirm advertised electric range.
  • Ask for hybrid-system/EV software update history and any scheduled high‑voltage battery or inverter service requirements and warranty details.
  • On a test drive check automatic transmission smoothness, regenerative braking transition, and 12V electrical behaviour (startup and accessory functions).

Vehicle description 2026 BYD SEAL U DM-i BOOST FWD – GREY – 23,860KM – €40,890 NCT Tested till 10/03/2030 261 MODEL – PLUG-IN HYBRID SUV – €40,890 – SERIOUS VALUE Here is another fantastic 2026 BYD SEAL U DM-i Boost FWD, finished in Grey, with 23,860KM and available for an excellent €40,890. This is a 261 / 2026 model, giving you the opportunity to move into a modern, highly equipped plug-in hybrid SUV with BYD's innovative Super DM-i technology, impressive electric driving capability and the added reassurance of petrol power for longer journeys. 2026 / 261 MODEL SEAL U DM-i BOOST FWD 217PS PLUG-IN HYBRID 18.3KWH BYD BLADE BATTERY FRONT-WHEEL DRIVE GREY 23,860KM REG: 261D26673 €40,890 €40,890 – SERIOUS VALUE ON A 261 MODEL At €40,890, this is a particularly attractive price for a 261 / 2026 SEAL U DM-i Boost. BYD Ireland's listed retail price for the SEAL U DM-i Boost FWD is €42,150 before metallic paint, putting this example €1,260 below the listed Irish retail price. That makes the combination of 2026 registration, 217PS plug-in hybrid technology and €40,890 pricing particularly interesting for anyone shopping the current market. SUPER DM-i PLUG-IN HYBRID TECHNOLOGY The SEAL U DM-i Boost combines a petrol engine with BYD's electric hybrid system and 18.3kWh Blade Battery. It delivers 217PS, with up to 80km of pure-electric WLTP range and up to 1,080km combined WLTP range. That flexibility is a huge part of the SEAL U's appeal. For shorter Irish journeys, you can plug the car in and make use of electric driving for commuting, school runs, shopping and local trips. For longer journeys, the petrol engine provides the freedom to continue travelling without depending entirely on public charging. Electric when you want it. Petrol flexibility when you need it. A PROPER FAMILY SUV The SEAL U is designed as a spacious five-seat SUV, with generous room for passengers and a practical 425-litre boot, increasing to 1,440 litres with the rear seats folded. That gives you the flexibility required for real family life, whether you're loading the weekly shop, luggage, pushchairs, sports equipment or heading away for the weekend. The comfortable driving position and spacious rear seating make it equally suited to everyday urban driving and longer trips around Ireland. HIGH-TECH INTERIOR One of the biggest strengths of the SEAL U is the amount of technology integrated into the cabin. The vehicle features a large touchscreen, digital driver information and BYD's connected technology, creating a modern interior that feels very different from a traditional petrol SUV. Highlights include: 15.6" Rotatable Touchscreen 12.3" Digital Driver Display Apple CarPlay & Android Auto BYD Intelligent Voice Control 4G Connectivity BYD App Connected Services Wireless Smartphone Charging Heated & Ventilated Front Seats Electric Front Seats with Driver Memory Heated Multifunction Steering Wheel Panoramic Electric Glass Sunroof Electric Tailgate Dual-Zone Automatic Climate Control Multi-Colour Ambient Lighting 19" Alloy Wheels BYD also includes NFC keyless entry and connected vehicle functions, adding another layer of convenience to everyday use. SMART TECHNOLOGY FOR IRISH ROADS The SEAL U DM-i is equipped with an extensive suite of driver-assistance technology. This includes front and rear parking radars, 360° view camera, Adaptive Cruise Control, Intelligent Cruise Control, Lane Keep Assistance, Blind Spot Detection, Lane Change Assist, Traffic Sign Recognition, Automatic Emergency Braking and rear cross-traffic alert and braking. For Irish drivers, the 360° camera is particularly useful around busy town centres, tight car parks and narrow spaces, while adaptive cruise control adds comfort on longer motorway journeys. CHARGE AT HOME – KEEP PETROL FOR THE LONGER JOURNEY One of the biggest reasons to consider a DM-i is how easily it can fit into everyday life. For customers who can charge at home, the SEAL U can be used much like an EV for shorter journeys, while the petrol engine gives you the flexibility to travel much further when required. BYD also supports Vehicle-to-Load (V2L) technology, allowing the vehicle's battery to supply power to compatible external equipment. BUILT FOR MODERN IRISH MOTORING Whether you're commuting around Dublin, doing the school run in Cork, travelling to Galway or heading across the country for the weekend, the SEAL U offers a combination of comfort, space and powertrain flexibility that makes sense for everyday Irish driving. It's a particularly attractive option for anyone who wants to make greater use of electric driving without giving up the convenience of petrol for longer journeys.
