The EQXX Concept features a crazy driving range.

Mercedes-Benz is putting its century-plus of automotive experience into building electric cars, and the results are impressive. The EQS is an electric flagship with great range, and the automaker has unveiled several concepts to show its future plans. The Vision EQXX concept debuted today as an ultra-efficient luxury EV with astonishing range numbers.

Mercedes‘ focus with the EQXX is efficiency over power, as it says the car is its most efficient it has ever made. The EQXX uses less than 10 kWh per 100 kilometers (around 62 miles), which equates to 620 miles on a single charge. The battery was designed with tech and knowledge from Mercedes-AMG Formula 1 team, especially when it comes to size and weight. The EQXX’s battery pack is 50 percent smaller by volume and 30 percent lighter than the pack in the EQS, which already featured astonishing efficiency.

The car’s impressive range comes at the expense of horsepower, which in this case means just 201 ponies from the EQXX’s electric drivetrain. Mercedes says that the system is capable of delivering up to 95 percent energy efficiency – an impressive figure for power delivery to the wheels. Extremely efficient gas powertrains only achieve around 30 percent efficiency and a human long-distance runner can hit around 50 percent.

The EQXX is impressively slippery, which improves its range.

The EQXX is a slippery car, too, and with a drag coefficient of just 0.17, the car cuts through the air with ease. The typical EV uses up to two-thirds of its battery capacity just to push through the air, so the EQXX’s aerodynamics is a big part of its efficiency. The other big part is Mercedes’ thermal management system, which uses shutters and cooling plates to maintain an ideal battery and electric drive unit temperature. The plates allow the EQXX to gain about 12 miles of range in its most aerodynamic mode.
