Well its true and also false. Light cars take much less energy to accelerate. Cars with a small frontal area take much less energy to maintain at a particular speed...... So it does not look good for SUVs.
But, they can be made lighter... The ones based on old fashined pick ups are woefully out of date, in terms of construction. You dont get many aluminium chassied SUVs....
Also the Toyota hybrid SUV was getting something like 30mpg and good acceleration figures by storing energy from braking and coasting to later be used by an electric motor.... The same technology as their prius or the honda insight.
