Land Rover is trying its best to cut the CO2 emissions of its range of 4X4s. The British company has just announced that both the Discovery 4 and Range Rover Sport are getting a new 8-speed automatic transmission and modified engines which bring down CO2 levels to 230g/km (from 244g/km).
Now, that’s still a pretty hefty figure and places the vehicles in VED Band L which for 2011 means £445 per year road tax. It’s a shame the company couldn’t cut another 5g/km off the figure – that would have placed the 4X4s in Band K with £260 annual road tax.
Impressively, Land Rover has managed the CO2 reduction while increasing the power output of the 3.0-litre SDV6 diesel from 245hp to 256hp.
The mods are part of a host of new and refined features for the 2012 Model Year cars (Model Year starts in September, confusingly).
In conjunction with the new transmission, the Discovery 4 is now equipped with the ‘Drive Select’ rotary gear shift and steering wheel-mounted paddle shift.
There are two new alloy wheel designs, three new option packs and improved audio and navigation systems based on the latest electrical architecture. The entry-level audio system has now been upgraded with a colour screen replacing the previous black and white unit and available with Bluetooth, DAB and USB/iPod connectivity.
Off-road ability
Land Rover 4X4s set the standard off-road with the acclaimed Terrain Response system. For 2011, two additional functions were added, Hill Start Assist and Gradient Acceleration Control.
Hill Start Assist retains the initial driver-generated brake pressure long enough for the foot to move from brake pedal to throttle without the car rolling backwards. The brake is released after a sufficient time has elapsed or when the engine is supplying enough torque to move the car up the hill. Hill Start Assist is always available, not selectable, and neither is its operation indicated to the driver.
Gradient Acceleration Control is designed to provide safety cover on severe gradients when the driver does not have Hill Descent Control engaged. By pressurising the brake system, Gradient Acceleration Control slows the car to a limit determined by the throttle position when the car is descending the slope in the driver’s intended direction of travel. This includes descending the slope forwards in drive, or rearwards in reverse.
Vision Assist Pack
A new option pack is available to customers for 2012 – the Vision Assist Pack. Costing from £1000, the pack has Xenon front headlamps including cornering lamps, automatic headlamps with high beam assist and the surround camera system including approach lamps, tow assist and tow hitch assist.
