I prefer the Colin Chapman idea of smaller and lighter

You make the car lighter, you need smaller brakes, smaller tyres, smaller gearbox which makes it even lighter which means a smaller engine which makes it lighter and eventually you end up with a lovely small car.

You cannot imagine how slothful unfoucused and lardy a 7 makes even my old car which was a sporty BMW feel.

SUVs have there place but not on the road if you want my opinion cars are getting too heavy. the futre is smaller and lighter with clever materials. Look at the new top of the range jag made off alloy it is lighter then the X series which is bottom of the range.
