New exterior and interior colours are now available, along with a panoramic roof and new alloy wheel choices.
Both Range Rover and Range Rover Sport now offer an Aruba Silver paint finish, while Range Rover also adds Kaikoura Stone to the colour palate and 22-inch wheels to the options list.
The Sport can be optioned with body-colour roof and door sills, or a contrasting black finish.
Despite earlier predictions to the contrary, the Autobiography Black Long Wheelbase model can soon be ordered in Australia over and above the ‘regular’ Autobiography, available with an exclusive new Lunar/Cirrus interior colour combination.
The Autobiography Black comes with unique Santorini Black and Bright Chrome exterior trim, LED tail lamps, unique 21- and 22-inch alloys, new Semi-Aniline leather seat designs and customer-configurable mood lighting.
Add the Executive Class package, and the Black offers two individual fully-adjustable seats in the rear with an extended centre console, electrically-deployable leather tables, USB charging sockets, enhanced stowage and individual lighting.
The 4.4 litre V8 diesel option now has 740Nm of torque (up 40Nm) and a ‘fuller’ torque curve, while power remains at 250kW and fuel consumption is unchanged at 8.7 l/100km.
Land Rover says the torque improvements see in-gear acceleration times from fifth gear to eighth improve by up to 6.5 percent.
The eight-speed automatic transmission accompanying the SDV8 diesel has been upgraded, with a revised torque converter incorporating a twin-spring damper.
The supercharged 3.0 litre V6 petrol engine also gets a revised eight-speed automatic weighing six kilograms less than before, but power and torque are unchanged at 250kW and 450Nm.
Pricing for the 2015 Range Rover and Range Rover Sport in Australia will be announced closer to launch, with the new models expected to arrive locally later this year.
