A low drag means less fuel consumption. With a Cd value as low as 0.29 the new GLA occupies one of the leading positions in the segment of compact SUVs. These outstanding aerodynamics are the result of an intelligent combination of the following measures:
Automatically switching off the engine when stationary, for example in tailbacks or at traffic lights, lowers fuel consumption and emissions and saves fuel costs. The ECO start/stop function operates particularly effectively, quickly and quietly.
The function can be deactivated manually by a switch and is automatically suspended under certain conditions, for example, when the interior temperature falls below the selected temperature (linked to the climate control system).
Significant savings are the result of a series of small contributions. In the new GLA all important components were examined with regard to their energy need, and options to make them operate even more efficiently were uncovered.
The new GLA – like all Mercedes-Benz model series – is earmarked to receive an environmental certificate on the basis of the international ISO/TR 14062 standards (environmental management – integration of environmental aspects into product design and development). It rates the environmental compatibility of the new GLA over the entire lifecycle, from manufacturing to long years of use to recycling.
 The figures shown for fuel consumption and CO2 emissions were obtained in accordance with the prescribed measuring process (Regulation [EC] 715/2007 in its currently applicable version). The figures are not based on an individual vehicle and do not constitute part of the product offer; they are provided solely for purposes of comparison between different vehicle models
