As with the Discover 4, the Range Rover Sport’s more powerful 3.0-liter SDV6 diesel engine receives a 10HP boost lifting output from 245-horses to 256HP and is now mated to Land Rover’s new ZF 8HP70, 8-speed automatic gearbox. As a result, CO2 emissions have been reduced from 243g/km to 230g/km while combined fuel economy has improved from 30.7mpg to 32.1mpg UK.
Along with the new 8-speed transmission, the Range Rover Sport SDV6 now comes equipped with the 'Drive Select' rotary gear shift and steering wheel-mounted paddle shift.
Thanks to a low-flow fuel injection system, CO2 emissions for the entry level 211-horsepower diesel engine have been reduced from 243g/km to 224g/km.
The range-topping 5.0-liter supercharged V8 gasoline engine remains unchanged for 2012, continuing to deliver 510-horses and a 0-60mph (96km/h) sprint time of 5.9 seconds.
Other changes to the 2012 Range Rover Sport include new colors for the exterior and interior trims, a restyled powered single piece tailgate that is standard across the range, enhanced audio and infotainment systems and a next generation 7-inch touch-screen that is available with optional Dual View technology.
