Our opinion

The SEAL U DM‑i stands out for its long electric range for a PHEV, typically around 125 km in the Comfort trim, which makes daily commuting almost pure-electric if you charge consistently. Its total combined range, with petrol and battery, comfortably exceeds 1,000 km, which is exceptional for this class. The interior is roomy, with a flat floor and usable boot space, making it genuinely practical for families. Technology is another highlight: the rotating infotainment screen is large and intuitive, with connected services and over-the-air updates. It’s quiet in EV mode, and BYD’s reputation for reliability and safety adds extra reassurance. Cons The car’s biggest limitation is that it really needs regular charging to make economic and environmental sense. If you rely on the petrol engine alone, fuel consumption climbs, and the advantages of a PHEV diminish. The ride is tuned for comfort rather than agility, so body roll is noticeable on twisty roads, and the steering is light rather than precise. Some of the interior controls are screen-dependent, which may not suit everyone, and the petrol engine can feel underpowered if the battery is low. Like most PHEVs, it carries extra weight and system complexity, which can affect servicing and long-term reliability. Global Review Overall, the BYD SEAL U DM‑i is a practical, efficient SUV for buyers who want the flexibility of a plug-in hybrid without paying a premium. It competes well against mainstream European and Japanese PHEVs, offering longer EV range and total mileage at a lower price point. In real-world use, it rewards drivers who plan ahead and charge regularly, delivering very low running costs and long-range capability. It’s not about sporty driving or flashy luxury — it’s a well-rounded, functional vehicle for families and commuters alike. Range Accuracy & Ease of Charge In typical use, the SEAL U DM‑i offers around 125 km of all-electric range in the Comfort trim, though this will vary with speed, terrain, and driving style. Combined with the petrol engine, it can cover over 1,000 km between refueling and charging stops. Charging at home is straightforward, and while it doesn’t match the fast DC charging speeds of full EVs, it’s more than sufficient for overnight top-ups. For best efficiency and cost savings, charging regularly is essential; skipping it turns the car into a standard hybrid with higher fuel use. Space & Practicality Cabin space is generous, particularly in the rear, with a flat floor that allows for good legroom. The boot is practical at around 425 litres, expandable with fold-flat seats. Interior storage is well thought out, with multiple USB ports and even V2L capability to power devices directly from the car. The design is functional, focusing on usability rather than flair, but it meets everyday family needs comfortably. Driving & Handling The suspension prioritizes comfort, soaking up bumps on city streets and highways alike, though it does allow noticeable body roll on twistier roads. Steering is light, so it won’t feel engaging for enthusiasts, but it’s easy for daily commuting. EV mode is smooth and quiet, while the petrol engine engages seamlessly when needed, although it can feel less lively when the battery is depleted. Regenerative braking takes a short period to get used to but is effective once mastered. Ease of Use (Controls & Infotainment) The infotainment system is one of the car’s strongest points, featuring a large rotatable screen with integrated apps, navigation, and regular over-the-air updates. The digital instrument cluster is clear, and smartphone mirroring works well. Some menus require interacting with the touchscreen for climate and other basic functions, which might take getting used to if you prefer physical knobs, but overall the interface is modern and functional. Bottom line For buyers who will charge it regularly, the BYD SEAL U DM‑i is one of the best value PHEVs available today. It delivers long-range capability, low running costs, and family-friendly practicality at a competitive price. It’s not a sporty or luxurious SUV, but it does its core job very well: efficient, comfortable, and versatile transport for daily life and long trips. If you rarely plug in, or you’re after a dynamic driving experience, there are better alternatives. Competitors & Alternatives Key competitors include the Toyota RAV4 PHEV, which offers reliability and dealer support but at a higher cost; the Ford Kuga PHEV, which has a more dynamic chassis but slightly shorter EV range; and the VW Tiguan eHybrid, solidly built but with weaker electric range. The Kia Niro PHEV is smaller and cheaper, while the Peugeot 3008 PHEV offers style and a comfortable ride but less overall range. The Volvo XC60 PHEV is premium and capable but comes at a much higher price. For a daily mix of city commuting and motorway trips, the SEAL U DM‑i combines range, efficiency, and value in a way that most rivals don’t match.
