"If you are thinking SUV, it is less maneuverable because of higher center of gravity and maybe tires have different properties." SUVs and pickups. That is what we have around here. "As far as size and weight I have to think physics here: Is there any reason you can think of why a car that of size X would be any more maneuverable than a the same care scaled to size and weight of 1.1 X?" In general, the higher the mass, the more inertia at a given speed. But, that can be compensated for if it is a design goal. Lowering the center of gravity and stiffening the suspension and running higher tire pressure along with taking measures to reduce body roll like sway bars and such. The problem, though, is stiffening the suspension and running with higher tire pressure makes for a rougher ride. Reducing body roll means higher g-forces transmitted to the passengers. And some people feel this makes for a more uncomfortable ride. So, especially for large cars intended for the luxury market, their handling just isn't as good as their lighter brethren because of the greater force transmittal during vector changes.
