Compact at rear, Packing is too low

Its main major concern is compact at rear seat, and i feel its packing is not good ,as I have feel bad sounds on bumpy and macadamized roads, As compare to Hyundai cars. Boot space is not so big, i have driven this car since 2018 mileage is good power and pick up is awesome. Low maintenance cost. As its a compact car its ground clearance is good ideally for hilly areas. And the most important positive point is its too much smoothy on snowy roads during winter.
