The xDrive designation used on BMW vehicles is reserved for models equipped with intelligent all-wheel drive. However, different BMW models have different types of xDrive.
Škoda models bearing the e-TEC designation are equipped with a mild-hybrid drive system. In these cases, the function of the combustion engine is supplemented by an electric motor to assist the conventional combustion engine.
The sDrive designation for BMW vehicles was originally reserved for rear-wheel drive models only. Today, you can also find this designation on front-wheel drive BMW models.
