The vehicle uses BYD's fifth-generation DM (Dual Mode) Super Hybrid system, branded DM-i, which pairs a petrol engine with a front-mounted electric motor and an LFP Blade Battery . This setup allows for everyday electric-only driving while eliminating range anxiety on longer journeys.
The Dolphin G DM-i is physically larger than the electric Dolphin Surf sold in Europe. The increased dimensions accommodate the PHEV hardware, including a fuel tank, engine, and a more complex exhaust system.
| Dimension | Dolphin G DM-i (PHEV) | Electric Dolphin / Dolphin Surf (BEV) |
|---|---|---|
| Length | 4,160 mm | 4,125 mm |
| Width | 1,825 mm | 1,770 mm |
This means the plug-in hybrid is 35 mm longer and 55 mm wider than its electric counterpart. The standard electric Dolphin remains BYD's most compact and accessible BEV offering in Europe, but the Dolphin G's slightly larger footprint is a direct consequence of its dual-power nature .
While BYD hasn't yet published the final technical specifications for the Dolphin G itself, the industry consensus is that it will share its core propulsion system with the previously launched Atto 2 DM-i (known as the Yuan Up DM-i in China) .
Based on that system, the expected specs are:
Two LFP battery pack options are expected—a smaller 7.8 kWh unit and a larger 18 kWh pack—directly carried over from the Atto 2 DM-i architecture .
Range is the Dolphin G's headline feature. BYD is positioning the car as an antidote to electric vehicle range anxiety.
BYD has stated the car will be offered at an "affordable" price, and some UK media have already described it as "set to be UK's cheapest plug-in hybrid" . However, no official price list has been released.
The global debut is scheduled for June 2026, with first customer deliveries across Europe expected in the autumn of the same year .
A critical piece of the puzzle lies in Szeged, Hungary. BYD’s first European passenger-vehicle factory began trial production in the first quarter of 2026, with mass production slated to ramp up in the second quarter . The Dolphin G DM-i is widely expected to be one of the first models to roll off the Hungarian assembly line
. Local "Made in Europe" production would allow BYD to supply the EU market without incurring any import duties from China, even if trade rules were to evolve.
To understand the Dolphin G, you have to look at the EU's tariff structure. In October 2024, the European Union imposed definitive countervailing duties on battery electric vehicles (BEVs) imported from China . For BYD, these duties added a 17% tariff on top of the standard 10% import levy, creating a 27% total duty that significantly eroded the brand's price advantage
. These tariffs are applied for a five-year period
.
Crucially, these tariffs are specific to pure battery-electric vehicles. They do not apply to plug-in hybrid vehicles .
BYD's strategy with the Dolphin G therefore rests on two pillars:
This move is part of a broader industry pivot. Since the tariffs took effect, Chinese automakers have sharply increased PHEV exports to Europe . PHEVs also serve a growing demographic of European buyers who are not yet ready to commit to a full BEV, allowing BYD to widen its market coverage while navigating trade disputes
