Quick Verdict
The Seal 6 DM-i is BYD’s mainstream plug-in hybrid saloon — and, in Touring form, one of the very few affordable PHEV estates on sale in Europe. The pitch is simple: around 100 km (62 miles) of real electric driving for the daily routine, a petrol engine for everything else, and a combined range of up to 1,350 km. For households that can’t fully commit to an EV, this is BYD’s most rational car.
Best for: High-mileage drivers, company car users, and families who want electric running costs without charging-network dependence — especially estate buyers, who have few PHEV options at this price.

How DM-i Works
DM-i (“Dual Mode intelligent”) is BYD’s Super Hybrid system: the car drives primarily as an EV, with the 1.5-litre petrol engine acting mostly as a generator, connecting directly to the wheels only at higher cruising speeds where that’s more efficient. In practice:
- Commuting with home charging: you’ll use almost no petrol at all
- Long trips: the car behaves like an efficient full hybrid — no charging stops needed
- Depleted battery: unlike many PHEVs, DM-i stays efficient because the system was designed hybrid-first

The Touring: The Interesting One
Estate buyers have been abandoned by the market — most affordable PHEVs are SUVs. The Seal 6 DM-i Touring offers:
- 675 litres of boot space (more than a Passat), expanding to ~1,535 L
- Standard panoramic sunroof
- Lower load lip and better dog/bike/tip practicality than an equivalent SUV
At around £35,000 it effectively has the affordable-PHEV-estate segment to itself in the UK.
China Context
In China this car is the Seal 06 DM-i (海豹06), one of BYD’s best-selling models with monthly volumes European brands can only dream about. That matters for buyers here: the powertrain arrived in Europe with well over a year of mass-market service history, and the fifth-generation DM-i system it uses is the same technology that took BYD’s hybrids to a claimed 2,000+ km range in Chinese-cycle testing. Export versions get European chassis tuning and WLTP-rated (more conservative and realistic) range figures.
Running Costs
- Charge at home overnight and a ~100 km electric range covers most UK daily mileage profiles — expect fuel bills to collapse
- Weighted WLTP consumption of ~1.7 L/100 km is theoretical; real-world with regular charging typically lands between 1–3 L/100 km, and 5–6 L/100 km if you never plug in
- BYD’s 6-year vehicle warranty applies; see the warranty guide
Best Alternatives
- Volkswagen Passat eHybrid — more polished, significantly more expensive
- Skoda Superb iV — huge and refined, again a price class above
- MG HS PHEV — cheaper SUV alternative with less EV range
- BYD Seal U DM-i — same powertrain philosophy in SUV form; see the Seal U DM-i guide
Verdict
The Seal 6 DM-i is the car to recommend to anyone who says “I’m not ready for a full EV.” The saloon is competent; the Touring is quietly one of the smartest family-car buys in the 2026 market because nothing else offers this combination of estate practicality, electric commuting, and price. It won’t excite anyone — it will just cost very little to run.
