Besides its more athletic underpinnings, the 2006 Land Rover Range Rover Sport wears a design that differs slightly from its big brother, the Range Rover. The Sport has a less boxy shape, due in part to the steeper rake of the front and rear windows and the diminished greenhouse. Both front fenders include unique side vents, and the sloping rear roofline is accented by a body-color spoiler. One of those side vents allows hot air to escape the engine compartment, while the other is an air intake point for the engine.
