The EQA is being launched as the EQA 250 (combined electrical consumption: 15.7 kWh/100 km; combined CO2 emissions: 0 g/km) with 140 kW and a range according to NEDC of 486 kilometres. Further variants to meet specific customer requirements will follow. These will include on the one hand a series of even more athletic all-wheel-drive models with an additional electric powertrain (eATS) and an output of 200 kW or more, and on the other hand a version with a range of more than 500 kilometres (WLTP)4. Mercedes-EQ sees the key to a bigger range not in ever-larger batteries, but in systematic improvement in the efficiency of all vehicle components.
Navigation with Electric Intelligence calculates as a matter of course the route that will get you to your destination fastest, taking into account charging times, thus taking the stress out of route planning for the driver. On the basis of continual range simulations, the system makes allowance for any necessary charging stops as well as for numerous other factors, such as the topography and the weather. It is also able to react dynamically to changes, for instance in the traffic situation or personal driving style.
With Mercedes me Charge, customers have access to what is currently the world’s biggest charging network: this currently comprises more than 450,000 AC and DC charging points across 31 countries. Mercedes me Charge allows customers convenient use of the charging stations of various providers, even when travelling abroad. By registering just once, they can benefit from an integrated payment function with a simple billing process.
Mercedes me Charge enables customers to charge at more than 175,000 public charging points throughout Europe; Mercedes-Benz ensures a subsequent offset with green power.
Low wind resistance means high efficiency – something that is particularly important with electric vehicles. The EQA is the first model from Mercedes-EQ whose aerodynamic development has been undertaken entirely digitally. The ensuing measurements undertaken in the wind tunnel revealed a Cd value of 0.28, thereby confirming the high quality of the numerical simulation. The frontal area A totals 2.47 m2. Among the most important aerodynamic measures are the completely closed cooling air control system in the upper section, the aerodynamically efficient front and rear aprons, a very smooth, almost completely enclosed underbody, specially optimised Aero wheels and specifically adapted front and rear wheel spoilers.
Efficiency was key when designing the thermal architecture too. Thanks to the heat pump that is fitted as standard, the waste heat from the electric powertrain can be used to heat the passenger compartment. This reduces drastically the draw on battery power for the heating system, thus increasing the range. It is also possible to set the pre-entry climate control for the interior of the EQA before starting. This function is controlled directly from the MBUX infotainment system or via the Mercedes me App.
Remarkable effort has been put into ensuring that the car meets the high level of noise and vibration comfort that is such a hallmark of the brand, including the systematic isolation of the electric powertrain from the chassis and body. Numerous damping measures designed to prevent the transmission of airborne sound serve the same purpose.
