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.
Mercedes GLB
Skoda Kodiaq
VS
The Mercedes GLB dresses up compact practicality in a premium suit, with crisp tech and city-friendly manners, while the Skoda Kodiaq goes full-on family hauler, offering cavernous space and sensible value. Choose the GLB for style and badge appeal; pick the Kodiaq if you need seats, luggage and a boot that could double as a small country.
