The new Mercedes-Benz A-Class: Aerodynamics - Saving fuel the aerodynamic way ~ mercedes gla
The exterior mirrors and the low stepped height of the A-pillars reflect the fact that the work conducted in the wind tunnel was not just about optimising the flow conditions, but also about minimising
wind noise. And in addition to aerodynamics and aeroacoustics, there is often another discipline to consider: in terms of
water management too, the flow around the exterior mirrors and the A-pillars also has to be optimised in the wind tunnel in order to guarantee good visibility is maintained towards the rear and at the sides during wet weather.
