Fresh versions of the Range Rover, Range Rover Sport and Land Rover Discovery made their world debuts at the New York Motor Show – and they all benefit from more luxurious cabins and new engines.

Confirming its place at the top of the pile is the Range Rover. A remoulded bumper, repositioned foglamps and more compact grille give the front a cleaner, more contemporary look, while light clusters front and rear are now lit up with LEDs.

Power comes from supercharged versions of Jaguar Land Rover’s all-new 5-litre V8 powerplant, delivering an ample 503bhp. Diesel fans can still order the 268bhp TDV8.

Inside, luxury-grade leather can be specified on the pillars and headlining for an extra £2500 – which leaves every inch of the cabin covered in hide. An all-new 12-inch TFT screen replaces the traditional analogue dials, so the speedo and odometer are displayed in hi-res graphics instead.

The real headline grabber in the Range Rover, though, is the world’s first dual-view screen. Derived from 3D TV, it allows the driver to view satellite navigation directions from one angle, while the front seat passenger watches a film on the same display.

For the Range Rover Sport, focus was on improving the driving experience. New Bilstein adaptive dampers are fitted, as is speed-sensitive steering. Plus, the Terrain Response system has been tweaked to include a Dynamic mode, giving quicker gearshifts.

Engine choices include the same naturally aspirated and supercharged 5-litre V8s as the RR, as well as the V6 twin-turbo diesel from the new Jaguar XF S. A more simple twin-bar hexagonal grille and new LED lights set the Range Rover Sport apart on the outside, while touchscreens give the cabin a less cluttered layout.

The Discovery gets a matching hexagonal grille, body-coloured arches and optional 20-inch alloys, plus better materials and a more minimalist design inside. Sales of the new models are set to start later this year, with subtle prices rises likely.
