Mercedes-Benz has unveiled the Vision EQXX, a particularly energy-efficient electric car. The 900-V concept vehicle is said to be able to achieve a range of over 1000 km on one battery charge.

The exterior design of the Vision EQXX combines the design language of sensual purity with optimized aerodynamics. The drag coefficient is just 0.17. To achieve this, the engineers have combined the streamlined basic shape with a rear track that is 50 mm narrower so that the rear wheels are in the slipstream. Aero elements such as an air curtain in front of and an air vent behind the front wheel arches and aero wheels with tires optimized for rolling resistance are also used. The retractable rear diffuser ensures reduced drag from 60 km/h and increased driving stability. The cooling plate in the underbody of the vehicle uses the airflow to cool the powertrain.
This was developed in collaboration with the Formula 1 experts at Mercedes-AMG High Performance Powertrains (HPP) and consists of an electric motor, transmission and power electronics with a new generation of silicon carbides. The inverter is based on that of the Mercedes-AMG Project One hypercar. Maximum output is 150 kW (204 PS), and efficiency is said to be 95 %. In addition to the cooling plate, the thermal management system consists of additional air flaps at the front, coolant valves and water pumps.
Small and lightweight battery pack
The highly integrated battery pack stores just under 100 kWh of energy, partly due to the higher silicon content of the anodes, but is only half the size and 30 % lighter than the battery pack in the EQS. According to calculations by Mercedes engineers, the concept vehicle, which weighs around 1750 kg, can travel more than 1000 km on one battery charge, which would correspond to energy consumption of less than 10 kWh per 100 km. Up to 25 km of additional range is also provided by 117 solar cells on the roof.
In the cockpit, the driver and front passenger look at a 47.5" display that extends from one A-pillar to the other. It works with an enhanced voice assistant and offers a real-time 3-D navigation system, among other features. The interior also uses sustainable materials made from recycled PET, a vegan leather alternative or carpets made from bamboo fiber. The temperature of the interior is controlled by a heat pump.
