Some more goodies and performance improvements from the green oval

Land Rover has made updates and added goodies to the Range Rover and Range Rover Sport; they'll be in New Zealand-spec models from early next year. These include engine revisions All-Terrain Progress Control, gains in performance and efficiency and a Head Up Display that projects key driving info onto a small area of the windscreen. Data includes vehicle speed, gear position and shift indicator, cruise-control information and satellite-navigation instructions. The driver can pre-select which information is displayed.

All-Terrain Progress Control (ATPC) allows the driver to select a desired speed without any pedal input once the brake is released. The system monitors and adjusts vehicle settings to optimise traction and maintain progress. It's meant to reduce driver workload over steep gradients, rough terrain and low-grip surfaces or wherever a very low constant speed is desirable. ATPC works both in forward and reverse from 1.8km/h to 30km/h.

Previously equipped with twin-turbocharging technology, the TDV6 derivatives change to a ball-bearing single turbocharger. Along with Low Pressure Exhaust Gas Recirculation (LPEGR), a two-stage oil pump that reduces parasitic engine losses and a revised design of fuel-injector nozzle, the TDV6 continues to produce 190kW and 600Nm. However, Land Rover says fuel efficiency improves; the Range Rover TDV6 by 8.5 per cent and the Range Rover Sport TDV6 by 5.7 per cent. Range Rover Sport SDV6s retain parallel-sequential turbocharging, but detail calibration changes increase performance to 225kW and 700Nm, up by 10kW and 100Nm. LPEGR, a two-stage oil pump and revised fuel-injector nozzles also increase fuel efficiency. The result is said to be a 7.0 per cent improvement at 7.0 litres per 100km.

Fitted with a 3.0 litre V6 supercharged engine, Range Rover and Range Rover Sport SCV6 derivatives continue to deliver 250kW and 450Nm, while fuel efficiency improves by 1.9 per cent. A new thermostat allows the all-alloy engine to reach its ideal operating temperature faster, while laser-drilled injectors ensure a finely optimised spray of fuel directly enters the combustion chambers; elsewhere, revised camshaft chain guides, a two-stage oil pump, a new diamond-like coating for the piston and gudgeon pin, and lower viscosity oil combine to reduce friction and improve efficiency.
