BYD has introduced the Dolphin G DM-i to the UK market, marking the arrival of the first plug-in hybrid in the supermini category. Starting at £23,990, the vehicle aims to capture a significant portion of the B-segment market by offering a bridge between traditional combustion and full electrification.

The 27.5 per cent B-segment gap BYD is filling

The launch of the BYD Dolphin G DM-i is a calculated move to dominate a specific niche in the British automotive landscape. According to the source, the B-segment represents the second-largest portion of the UK market, holding a 27.5 per cent share in 2024 based on data from the Society of Motor Manufacturers and Traders (SMMT). Until this release, no plug-in hybrid (PHEV) was available in this specific size category.

This strategic entry comes at a time when UK plug-in hybrid sales grew by 35 per cent last year. By introducing a small-car PHEV, BYD is positioning itself to attract buyers who are deterred by the high cost of petrol—exacerbated by conflicts in Iran—but are not yet ready to commit to a full battery electric vehicle (BEV).

A £23,990 entry with 633 miles of total range

The BYD Dolphin G DM-i offers a value proposition centered on range and affordability. the base model, priced at £23,990, provides 24.8 miles of electric-only range and a combined total range of 633 miles. For those seeking more electric capability, the Boost specification increases the price to £26,990 but extends the electric-only range to 65 miles, as reported in the source.

This range capability is powered by BYD's proprietary Blade Battery technology.. The company's ability to bring the Dolphin G DM-i to market quickly is a result of a nimble manufacturing process that allows BYD to develop new vehicle models in as little as 18 months, giving them a speed advantage over traditional European legacy automakers.

The 12.8-inch screen and the Apple CarPlay glitch

Inside the cabin, BYD has focused on prvoiding a high-tech feel that mimics premium vehicles. The base Dolphin G DM-i comes with a 10.1-inch touchscreen and an 8.8-inch digital instrument panel. those who opt for the Boost trim receive an upgraded 12.8-inch infotainment screen, along with luxury additions like a heated steering wheel and wireless charging.

However, the user experience is not without its frictions. During a test drive of the Boost trim, the report says that Apple CarPlay required the user to share their contacts to establish a connection. It remains unclear whether this is a widespread software flaw across all BYD Dolphin G DM-i units or an isolated issue with a specific test vehicle.

Can the Dolphin G DM-i outpace the Renault 5 and VW Golf?

While the BYD Dolphin G DM-i wins on utility—offering 425 litres of boot space plus an additional 45 litres under the floor—it faces a steep climb in terms of brand prestige and style.. The vehicle's "ocean-influenced" design is described as neat but lacks the retro-chic appeal of the Renault 5 or the premium status associated with the Volkswagen Golf.

The car's aesthetic is compared to a "dulled down" version of the Cupra Born, with some critics noting that the orange and blue color options can look like a box of Tic Tacs . The ultimate question for BYD is whether UK consumers will prioritize the practical benefits of a 633-mile range and low running costs over the emotional appeal and heritage of established European rivals.
