Benz goes efficient with F1 tech and ultra-slippery aero
Company calls it its most efficient vehicle yet
Mercedes-Benz created the Vision EQXX with one purpose: Make the most efficient vehicle the company was capable of, using F1 tech, tearing up the design playbook, and adopting battery tech not available even for the EQS that is launching right now.
1,000 km (621 miles) on a 100 kWh charge is what Mercedes-Benz says is possible. That’s 10 kWh per 100 km or 6 miles per kWh. Half the energy use of other current EVs and enough power to run a home dryer for three hours.
It’s the bodywork of the Mercedes-Benz Vision EQXX that will grab your attention, a shape that cuts through the air with a drag coefficient of just 0.17. It has a tail narrower than the nose and a flowing greenhouse along with multiple closing flaps that channel air for cooling and other functions only when needed.
A 100 kWh battery (usable capacity) is half the physical size of the similar capacity pack used in the EQS and weighs 30 percent less. That let Mercedes-Benz fit it into the smaller footprint of the EQXX. The power system has “an absolute focus on reducing losses” which means 95 percent of battery energy ends up at the wheels. The power system was developed with the automaker’s F1 team and is based on the system destined for the Mercedes-AMG Project One hypercar.
Chassis tech includes new casting technology to design the rear floor as well as using organic design methods and adding renewable plastics to reduce weight and dampen noise. Other chassis changes include using aluminum brake rotors instead of cast iron, helping to slash kilos at the wheels, as well as using glass-fibre reinforced plastic springs in the suspension.
Mushroom roots used to create a vegan leather alternative, cactus-based Deserttex leathers, bamboo carpets, and artificial silk door pulls are all part of the innovation inside, along with heavy use of recycled PET plastics. All are designed to lower the impact of the vehicle on the planet.
Mercedes-Benz calls this a concept, but the Vision EQXX looks far more production-ready than most Mercedes-Benz concepts. Does that mean production of the 201 hp electric is imminent? All the company is saying is that “many of the innovations in the Vision EQXX could be quickly adapted for production applications.”
