Electric flagship Mercedes-Benz EQS will offer a range of 770 km and excellent aerodynamics

The full-fledged debut of the Mercedes-Benz EQS liftback, which will become the most prestigious model of this German brand’s electric car, is scheduled only for April 15th. Today it became known that the EQS will surpass all production cars in terms of aerodynamic drag coefficient, and the battery charge in the maximum specification will be enough for 770 km of run.

The aerodynamic drag of the body makes a significant contribution to the energy consumption for moving the car and the noise level it creates in the perception of those in the cabin. Recessed door handles have appeared on Tesla electric vehicles precisely to reduce aerodynamic drag. The Lucid Air developers have so far managed to maintain the lead in terms of the best aerodynamics, but their electric car has not yet become serial, and the brainchild of Daimler will debut in a few days. Mercedes-Benz EQS flaunts a drag coefficient of 0.2 versus 0.21 for Lucid Air, which is the best indicator among production cars!

German engineers worked on the body shape of the EQS and sunk the handles in the door, and optimized the design of the rims. Hybrid Toyota Prius paid attention to this aspect already several years ago, equipping ordinary alloy wheels with special aerodynamic plastic covers. Of course, the bottom of the EQS had to be covered with a set of aerodynamic shields, but this has long been a well-known practice. Such convention as the number of side windows was also sacrificed for aerodynamic optimization – it was increased from two to three on each side.

The traction battery, according to the manufacturer, was developed by the Daimler concern on its own. The cobalt content in its electrodes is reduced to ten percent, manganese accounts for the same amount, and nickel forms 80%. Mercedes-Benz uses an older 400-volt power architecture, while German competitors from Volkswagen are starting to move to 800-volt. The EQS model will be offered with two options for the traction battery capacity, which is integrated into the body structure: 90 or 107.8 kWh. According to the conditional WLTP cycle, this energy reserve will be enough for 640 or 770 km of run, respectively. The company offers a ten-year battery warranty with free replacement in the event of loss of capacity. There is, however, a mileage limit – no more than 250,000 km.

Daimler also does not bend with the maximum power of the charging station – it does not exceed 200 kW, although this figure reaches 250-270 kW in competitors. The EQS can receive an amount of electricity in fifteen minutes in the maximum mode, sufficient to overcome 300 km. The standard charger supplied with the machine has a power of no more than 22 kW. With regenerative braking, you can recover up to 290 kW of electricity.

The EQS can be offered in both RWD and AWD variants. A 255 kW electric motor is located on the rear axle and 135 kW on the front axle in the latter case. In horsepower more familiar to motorists, the rear-wheel-drive EQS produces 333 power units; the all-wheel drive is comparable to a herd of 524 horses. The maximum speed in all cases is limited to 210 km / h, and the acceleration time to “hundreds” is not indicated. AMG will present its version of the EQS with even more impressive driving dynamics. In Europe, electric vehicles of this series will start selling in August this year.
