All-Terrain Progress Control (ATPC) is a world-first technology, which allows the driver to input a desired speed, either from rest or an existing speed, without any pedal inputs once the brake is released. The system continuously monitors and adjusts the vehicle settings to optimise traction and maintain progress. In other words, think of it as an off-road cruise control; no more careful feathering of the go pedal – the vehicle will do the tricky stuff for you. Great if you’re a novice wanting to explore off-road in your £100k toy, especially when slow speed may be required; but not so great if you enjoy testing your off-roading skills.
ATPC works both in forward and reverse gears, at speeds ranging from 1mph to 19mph. It’s a £175 optional extra, now available on the Range Rover TDV6, Range Rover Sport SDV6 (not including SDV6 Hybrid) and all V8 Supercharged derivatives (when specified with dual-range transmission and Terrain Response® 2). We expect Land Rover will extend the technology to its other models in future.
Land Rover today also announced upgrades to its TDV6 and SDV6 diesel engines, as found in the Range Rover and Range Rover Sport respectively.
Power and torque remain unchanged for Range Rover’s TDV6 engine (254bhp and 442 lb ft torque), but fuel efficiency improves by 8.5% to 40.9mpg, thanks to 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 two turbochargers have also been replaced with a new single one.
Meanwhile the Range Rover Sport’s SDV6 engine has an increase in power from 288bhp to 302bhp, and keeps its parallel-sequential twin-turbo setup. Torque is now a stonking 516 lb ft, and fuel efficiency is improved by 7% to 40.4mpg.
CO2 outputs for the TDV6 and SDV6 are now an impressive 182g/km and 185g/km respectively.
Head-Up Display (HUD), launched with the Evoque last month, is also now available across the Range Rover range for an extra £1000. There’s also an updated range of colours, including the evocatively-named Yulong White (Yulong is a snow-covered mountain range in southern China whose highest peak has not been climbed since 1987).
