The 2015 Rang Rover and Range Rover Sport SUVs will boast enhanced off-road ability, more powerful and more efficient engines, and additional equipment when production of updated versions begins in January.
Set for Australia in March, the premium four-wheel-drive duo will become the first to feature Land Rover’s new All-Terrain Progress Control (ATPC) system.
ATPC allows drivers to set their desired speed, either at rest or when driving, without any pedal inputs, and leave the car to maintain a constant vehicle speed while continuously monitoring and adjusting vehicle settings to optimise traction and maintain progress.
The system is designed to reduce driver workload while the vehicle operates at the limits of its off-road ability over steep gradients, rough terrain and low-grip surfaces. It works in both forward and reverse gears between 2km/h and 30km/h.
The 3.0-litre TDV6 diesel engine has undergone a major overhaul. It trades its previous twin-turbo layout for a single turbocharger, yet power and torque remain at 190kW and 600Nm respectively. The updated engine features low-pressure exhaust gas recirculation (LPEGR), a revised fuel-injector nozzle, and a two-stage oil pump that reduces parasitic engine losses.
Fuel consumption falls 8.5 per cent in the Range Rover TDV6 and 5.7 per cent in the Range Rover Sport TDV6, taking both down to 6.9 litres per 100 kilometres.
The Range Rover Sport SDV6 gets the same enhancements but retains its twin-turbocharged 3.0-litre diesel. Power rises 10kW to 225kW and torque 100Nm to 700Nm, yet fuel consumption falls 7.0 per cent to 7.0L/100km.
The supercharged 3.0-litre V6 Range Rover and Range Rover Sport SCV6 variants continue to deliver 225kW and 450Nm while fuel consumption falls 1.9 per cent (to 10.7 and 10.5L/100km respectively) thanks to a new thermostat, laser-drilled injectors, revised camshaft chain guides, a two-stage oil pump, diamond-like coating for the piston and gudgeon pin, and the use of lower viscosity oil.
Both models will also be available with a head-up display, which projects vehicle speed, gear position and shift indicator, cruise control information and satellite navigation instructions. HUD production will begin in March, with vehicles to reach Australia by May.
Both are available in new Yulong White paint, while the Range Rover Sport will also be offered in Kaikoura Stone.
The announcement comes less than three weeks after Land Rover Australia expanded its Range Rover Sport line-up with the new TDV6 S ($92,600 before on-road costs) and HSE Hybrid ($146,900) and Autobiography Hybrid ($165,300) variants.
