    • Our world-first All Terrain Progress Control system reduces your driving workload in challenging off-road conditions.

      The innovative technology can help drivers of all experience levels to enjoy the Range Rover’s peerless capability on off-road adventures.

      What is it?

      All Terrain Progress Control (ATPC) automatically maintains a set speed during off-road driving, maximising traction and allowing the driver to concentrate on the terrain and the vehicle’s course.

      What does it do?

      ATPC acts as a low-speed “cruise control” for off-road driving, automatically managing the engine output and the brakes to minimise any loss of traction and to maintain the target speed the driver has set. The driver can then focus on steering and assessing the terrain ahead, making off-road driving easier and safer.

      A RANGE ROVER USING ALL TERRAIN PROGRESS CONTROL OFF-ROAD

      What’s the difference between All Terrain Progress Control and the Terrain Response system?

      All Terrain Progress Control is an off-road ‘cruise control’ which maintains a steady, slow speed in tough off-road conditions, allowing the driver to concentrate on steering and assessing hazards. Terrain Response is a system which provides several driving modes, each of which tunes vehicle settings to ensure the best combination of traction and vehicle response for a particular terrain. Both have the same goal: to make it easier and safer to utilise the exceptional capabilities of our vehicles, whatever the conditions.

      When will you use it most?

      It’s particularly useful in off-road conditions in which maintaining a consistent, low speed is important. ATPC provides steady, controlled progress and limits wheelspin – ideal when ascending steep, slippery slopes or traversing rocky ground.

      How do you activate it?

      Press and release the ATPC button on the centre console. All the doors must be closed and the driver’s seat belt fastened before the system will engage. When ATPC is in operation the button will light up, and there’s also a warning lamp on the dashboard.

      What happens when you activate it?

      If ATPC is activated when the vehicle is stationary it automatically selects a descent control mode. When the brakes are released and the vehicle starts to move, ATPC will ensure the speed does not exceed 2.2mph with the gearbox in high range or 1.1mph in low range. The driver can press the accelerator to temporarily override the system, but as soon as the pedal is released ATPC will take over again.

      When ATPC is activated while the vehicle is moving at speeds between 2.2mph and 18.6mph, the full function mode is activated and the current vehicle speed is set as the target speed.

      How do you control ATPC?

      The cruise control buttons on the steering wheel can be used to control ATPC. The SET+ and – buttons will increase and decrease the target speed between 1mph – 18mph. The CAN button engages the descent control mode, and RES resumes the target speed after the driver has used the brakes to slow the vehicle.

      Which models have it?

      All Terrain Progress Control is either standard or optional on all Range Rover Evoque, Range Rover Sport and Range Rover models with an automatic transmission. It is available as a no-cost option on New Range Rover Evoque Convertible.

The figures provided are as a result of official manufacturer's tests in accordance with EU legislation. A vehicle's actual fuel consumption may differ from that achieved in such tests and these figures are for comparative purposes only.

The figures provided are NEDCeq calculated from official manufacturer’s WLTP tests in accordance with EU legislation. For comparison purposes only. Real world figures may differ. CO2 and fuel economy figures may vary according to wheel fitment and optional extras fitted. NEDCeq are figures calculated using a Government formula from WLTP figures equivalent to what they would have been under the old NEDC test. The correct tax treatment can then be applied.

The figures provided are WLTP. WLTP is the new official EU test used to calculate standardised fuel consumption and CO2 figures for passenger cars. It measures fuel, energy consumption, range and emissions. This is designed to provide figures closer to real-world driving behaviour. It tests vehicles with optional equipment and with a more demanding test procedure and driving profile.

TEL (Test Energy Low) and TEH (Test Energy High) figures are shown as a range under WLTP testing measures. TEL refers to the lowest/most economical figures (with the lightest set of options). TEH refers to the highest/least economical figures (with the heaviest set of options). WLTP legislation dictates that where there is <5g CO2 variance between TEL and TEH, only the TEH is declared.
