Despite undergoing a major facelift only last year, which saw the addition of a range of new engines and standard features, Land Rover’s latest 2011 Range Rover SUV has been updated again and the changes to the luxurious off-roader appear just as significant.

The 2011 Range Rover is further enhanced by improvements to the Terrain Response system in the form of Hill Start Assist and Gradient Acceleration Control. The luxury off-roader also benefits from an Adaptive Dynamics system, offering firm control of body motions through turns while providing the calm, composed ride.

Active safety aids include available Adaptive Cruise Control, Emergency Brake Assist, available Blind Spot Monitoring, available Automatic High Beam Assist and an available Surround Camera System.

Two engines remain on offer in the U.S., a naturally aspirated 5.0-liter V-8 with 375 horsepower and 375 pound-feet of torque, or a supercharged version of this engine with 510 horsepower and 461 pound-feet of torque on tap.

In Europe, the 2011 Range Rover has seen the addition of ZF’s brilliant eight-speed automatic transmission on the new LR-TDV8 diesel model. Available exclusively on the oil-burner, the new eight-speed automatic benefits from closer ratios for smoother comfort and a wider ratio spread for improved economy. U.S.-spec models stick with the current six-speed unit.

The LR-TDV8 features a 4.4-liter turbodiesel mill that makes 313 horsepower and 516 pound-feet of torque, and thanks to its eight-speed automatic it can hurtle from 0-60 mph in just 7.5 seconds. Fuel economy is a claimed 25 mpg for the European combined cycle.

To reflect the performance of the new LR-TDV8 engine, the 2011 Range Rover is fitted with the same Brembo-based braking system fitted to the 5.0-liter LR-V8 supercharged model. Providing the immense stopping power required for only the highest performing vehicles, the system comprises 380 mm ventilated front discs with unique, lightweight aluminum six-piston opposed action monoblock calipers. Smaller 365 mm discs with single piston sliding calipers are used at the rear.

Inside the cabin on all models are optional illuminated treadplates for the front doors and improvements to the entertainment system including as an option a 19 speaker Harman/Kardon premium sound system.

Incidentally, June 17 marks the 40th anniversary of the original Range Rover SUV so it’s only fitting that the company has used the date to announce an updated model. Additionally, to celebrate the milestone, a new Autobiography Black 40th Anniversary Limited Edition gives customers a more individual model to choose from.

With a unique finish in Barolo Black, the exterior also features 20 inch Diamond Turned alloy wheels, a unique front grille with Titan grille mesh, a bright chrome grille edge and black grille surround. Side vents have a new mesh set off by bright chrome bars and a black vent surround while the door handles are body color. It's all finished off by the 'Autobiography Black' tailgate badge.
