All Range Rovers for 2006 get a new front bumper design, new headlamps and taillights, a new front grille and revised power vents. New 19-inch alloy wheels are also offered. Two new engines add to Range Rover's performance upgrade. A normally aspirated 4.4-liter V8 engine produces 305hp, while a supercharged 4.2-liter V8 produces 400hp. The supercharged derivatives are distinguished by additional styling modifications including mesh-design front grille and power vents, unique 20-inch alloy wheels, and special black-on-silver badges. The '06 models will be available in the U.S. by mid-year 2005.
