The octane number indicates the ‘knock resistance’ of fuel. They are determined according to the RON (research octane number) under specific test conditions using precisely defined test engines. Normal petrol has the lowest level with a RON of 91, while Super petrol has an RON of 95, and Super Plus is at the top end of the scale with an RON of 98. The higher the octane number, the higher the autoignition temperature in petrols, and therefore the lower the knocking tendency during combustion (petrol 450-550 °C, Super 480-700 °C autoignition temperature).
Offroad driving program
The offroad driving program includes features such as Hill Descent Assist, a start function for tough terrain, adapted driving pedal characteristics and an ABS system specially optimised for off-road use. This allows the driver to control the vehicle easily on all terrains, at the touch of button.
Depending on the model, the offroad mode offers a special driving profile for challenging terrain. With the optional offroad bundle, two other offroad modes (sand and gravel) are available to select using the driving mode switch.
Thanks to Hill Start Assist and Hill Descent Assist systems, inclines become particularly easy to handle, as the system can regulate the vehicle’s climbing and downhill speed from an incline of 10%, within its limitations.
The on-board computer provides the driver with constant information on current or average fuel consumption via a dash panel display. The on-board computer also uses this information to calculate the range remaining with the current tank fill level. This information provides the driver with important hints regarding the most efficient, fuel-saving driving style possible. It is also possible to access additional information on average speed or total driving time.
