Car A
Mercedes-Benz GLS 450 4MATIC
A three-row, seven-seat luxury model with strong V6 biturbo performance and AWD, the GLS 450 4MATIC suits large families and long road trips. High fuel use and modest cargo space with all seats up are the main compromises.

Car B
KIA EV9 GT-Line
The KIA EV9 GT-Line blends seven-seat versatility and a 700-liter trunk with strong AWD performance and an estimated 400 km range. It’s well-suited to large families and road trips, but less ideal for tight-city or budget-focused use.
