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.
XPeng G9
ZEEKR 7X
VS
XPeng G9 arrives as a tech‑forward grand tourer — slick, serene and stuffed with autonomous driving toys and a luxurious, quietly sophisticated cabin; the ZEEKR 7X, by contrast, plays the sportier, more pragmatic card, delivering sharper handling, a brasher road presence and strong value for buyers who want engagement as well as space. Pick the G9 if you want plush, futuristic comfort and top‑end gadgetry; choose the 7X if you prefer a slightly firmer, more driver‑focused electric that gives more car for your cash — and a grin behind the wheel.
