BYD Dolphin
BYD Dolphin Surf
VS
The BYD Dolphin and the sportier Dolphin Surf share the same efficient electric bones, but the Surf adds visual muscle, slightly firmer suspension and sharper steering for anyone craving a bit more attitude. Inside they’re twins — clever packaging, roomy rear seats and a useful boot — so the Surf’s appeal is mostly about style and a touch of driver engagement, while the standard Dolphin is the softer, smarter everyday companion. If you want best value and comfort, stick with the Dolphin; pick the Dolphin Surf only if looks and a hint of sportiness top your checklist.
BYD Dolphin
BYD Atto 2
VS
The BYD Dolphin is a zippy, compact EV built for urban life — efficient, easy to park and kind on the wallet, making it a brilliant daily driver for city dwellers. The BYD Atto 2 swaps hatchback frugality for crossover comfort and tech, offering more space, range and kit for buyers who value relaxed longer trips and family practicality — Dolphin for tight streets, Atto 2 for everything else.
