Land Rover's engineers also sought to improve the LR4's on-road ride and handling, in addition to the acclaimed all-terrain capabilities of its predecessor. The changes include new suspension components, revised steering, larger brakes, improved traction control, and enhancements to the Terrain Response system, which helps optimize the vehicle for a variety of driving situations.

The engine has been optimized for low-end torque, making it possible to activate the lock-up clutch of the six-speed automatic transmission at lower speed. This reduces 'slip' in the hydraulic torque converter benefiting both fuel consumption and CO2 emissions. The higher torque at lower rpm also enables longer gearing for more economical cruising.

A more powerful brake system features four-piston calipers and 14.2-inch rotors in the front, with single-piston calipers and 13.8-inch rotors in the rear.

Four-corner independent height-adjustable air suspension and Land Rover's exclusive Terrain Response system are both standard across the range. Terrain Response is an adjustable suspension system with five settings: general, grass/gravel/snow, mud/ruts, sand, and rock crawl.

The fresh exterior design for 2010 onward includes smoother new front end and revised lights, including LEDs. The all-new interior delivers a more premium and functional five and optional seven-seat space. Other new features include available Surround Camera system, Gradient Release Control, Tow Assist, available Automatic High Beam Assist, Keyless Entry, and Push Button start.

Aerodynamic changes to the front end, with the revised front lower chin spoiler and new front wheel deflectors, help to reduce drag. 19-inch wheels and tires optimized for rolling resistance and improved tire wear also increase efficiency. The interior is completely redesigned, with a revamped dash and center console, new seats, and improved controls.

An electronically controlled six-speed ZF automatic transmission provides a wide spread of gear ratios. Three shift modes are available. In the automatic mode, up- and down-shifts are electronically regulated for smooth gear changes. In the Sport mode, shifting is keyed to maximum acceleration performance. In the CommandShift mode, the driver has manual control over the gears.

Other features include DVD-based navigation, a 240-watt or 550-watt sound system, third row seating, bi-xenon headlights, programmable key fob, and Sirius satellite radio.
