Its extraordinary streamlining has a decisive influence on consumption. That's why when planning the GLE we used state-of-the-art test procedures in order to develop measures to reduce drag as far as possible.The result: a drag coefficient of 0.32. One of the best in its class.
Apart from this, engine compartment and underbody panelling, which optimises the outflow of cooling air from the engine compartment and prevents flow loss caused by flow obstruction and turbulence around the vehicle underbody, also contributes towards an excellent drag coefficient.In addition, the roof spoiler on the boot lid reduces air turbulence.
The exceptional aerodynamics can also be directly appreciated in the vehicle interior: It has been possible to eliminate virtually completely all the noises caused by airflow and vibrations.
