If you’re looking for a family‑friendly SUV with low running costs and everyday practicality, plug‑in hybrids are a popular choice for UK drivers. Two standout options in this space are the BYD SEAL U DM‑i and the Hyundai Tucson Plug‑in Hybrid.
Both promise electric‑only driving for short journeys, strong equipment levels, and the reassurance of petrol power for longer trips. But how do they compare in real‑world UK use, and which one is right for you? We’re comparing powertrains, interior comfort, technology, driving experience, and running costs.
Powertrain and electric driving
The BYD SEAL U DM‑i uses BYD’s advanced DM‑i plug‑in hybrid technology, designed to prioritise electric driving wherever possible. In everyday use, this means most short commutes and local journeys can be completed using electric power alone, with the petrol engine stepping in smoothly when needed.
The Hyundai Tucson Plug‑in Hybrid also offers EV‑only driving, with an electric‑only range suitable for daily school runs or commuting. However, the BYD’s system is tuned to maximise electric efficiency and smooth, quiet progress, particularly at lower speeds. While both models offer usable EV range, the SEAL U DM‑i leans more heavily into electric‑first driving, which can help reduce fuel costs in day‑to‑day use.
Interior comfort and technology
Step inside the BYD SEAL U DM‑i and you’re immediately greeted by a modern, high‑tech cabin. Stand‑out features include a large, rotatable central touchscreen, digital driver display, heated and ventilated front seats (trim‑dependent), panoramic glass roof, and voice control and smart connectivity.
Hyundai’s Tucson Plug‑in Hybrid also offers a well‑built cabin with dual 12.3‑inch displays, a clean layout, and plenty of driver assistance technology. It feels familiar and polished, particularly for drivers already used to Hyundai interiors. Where BYD stands out is in how much tech comes as standard, even on lower trims, reducing the need to upgrade just to access comfort features.
Space and practicality
Both SUVs are designed with family use in mind, offering five doors, comfortable rear seating, and flexible boot space. The BYD SEAL U DM‑i provides a 425‑litre boot, expanding to 1,440 litres with the rear seats folded, ideal for buggies, bikes, or DIY runs. The flat boot floor and wide opening make loading easy.
The Hyundai Tucson Plug‑in Hybrid offers a 546-litre boot, extending to 1,799 litres with the rear seats folded, offering a larger capacity with its conventional SUV body.
Performance and driving experience
In normal driving, both cars prioritise comfort and ease of use over sporty handling, which is exactly what most family SUV buyers want. The BYD SEAL U DM‑i delivers smooth acceleration, quiet electric running at low speeds, and a relaxed feel on longer journeys. Alternatively, the Hyundai Tucson Plug‑in Hybrid offers slightly firmer handling, particularly in higher trims, and feels reassuringly planted on the motorway. Neither is designed to be a performance SUV, but both feel confident and capable for everyday UK roads. The Tucson may feel a touch more familiar to traditional SUV drivers, while the SEAL U DM‑i excels in refinement and electric smoothness.
BYD SEAL U DM i vs Hyundai Tucson
The Hyundai Tucson Plug‑in Hybrid will appeal to drivers who value a well‑established nameplate with familiar styling and a conventional approach to SUV design. It suits those who prefer the reassurance of a long‑standing brand presence in the UK market and want a plug‑in hybrid that feels immediately recognisable and traditionally laid out, particularly inside the cabin.
The BYD SEAL U DM‑i, on the other hand, is an excellent choice for drivers who want more technology and premium features included as standard, rather than having to step up through trim levels. It’s particularly well suited to those who intend to maximise electric driving for everyday journeys, value long warranty coverage for peace of mind, and are looking for strong overall value. With its spacious interior, refined driving experience and forward‑thinking design, the SEAL U DM‑i offers a modern, future‑focused alternative in the family SUV segment.
At BYD South West, the SEAL U DM‑i represents a new generation of plug‑in hybrid SUVs, blending advanced battery and hybrid technology with real‑world efficiency, high levels of comfort, and excellent value for money – all tailored to modern UK driving needs. Book a test drive today.
