This information would possibly sound like deja vu. Mercedes-Benz Imaginative and prescient EQXX, the model’s expertise demonstrator doing all of the arduous work in order that future road-going Mercedes EVs will be as environment friendly as attainable, simply lined 627 miles on a single cost. Sure, once more. However this time its vitality effectivity was even higher.
Mercedes engineers drove the Imaginative and prescient EQXX throughout the Arabian desert. The EV traveled from Riyadh, Saudi Arabia, to Dubai, UAE. It clocked an effectivity of 8.4 miles per kilowatt-hour, as its aerodynamic kind issue minimize via the air, battled desert warmth, and lined a whole bunch of miles on battery energy throughout empty highways.

Mercedes-Benz has taken a step again from EVs, however R&D continues.
Mercedes-Benz had dedicated to an all-electric portfolio by 2030. However with the latest EV gross sales slowdown worldwide, and an impending presidential election within the U.S. which may form the EV business going ahead, the German automaker has taken a step again. However that does not imply it is sitting idle. A brand new EV based mostly on the one-size-fits-all MMA platform will debut later this yr, and improvement for future EVs is underway as effectively.
In its first outing from Sindelfingen, Germany to Cassis, France, the EQXX lined an equally spectacular 626 miles however the effectivity was comparatively decrease at 7.1 miles/kWh. That was in 2022. Once more later the identical yr, the EQXX street tripped from Stuggart to Silverstone, masking 747 miles on a single cost, averaging 7.5 miles/kWh.
A 2023 Tesla Mannequin 3 Lengthy Vary AWD has an effectivity of about 3.8 miles/kWh, in line with the EPA. Though the Tesla is aerodynamic in its personal proper, it doesn’t have any of the extra aero chops of the EQXX. The Mercedes is extraordinarily slippery, with a drag coefficient of 0.17, higher than any manufacturing sedan.
It additionally will get a streamlined rear part with a further aero blade below the rear bumper stretching out and away from the physique to make the air exit from the undercarriage as easily as attainable. It’s additionally created from supplies you usually don’t see in inexpensive mass-market manufacturing automobiles, like weight-saving carbon fiber strengthened plastic.
So it’s unclear how a lot of this effectivity we’ll ever see in the actual world. That stated, it averaged 42.7 miles per hour, delivering 282 MPGe. The air con was on alongside the way in which, and a “multi-source warmth pump” minimized vitality losses, Mercedes stated. The EQXX has a 100 kWh battery capability based mostly on a 900-volt system structure.
“The EQXX continues to offer precious knowledge for the on-going improvement of superior electrical effectivity applied sciences. All programs carried out completely within the desert, dealing with challenges comparable to street floor end, temperatures, and dirt with ease,” Markus Schäfer, the chief expertise officer at Mercedes-Benz AG, stated. “It is additional proof that electrical drive is prepared for world markets.”
Mercedes-Benz additionally stated the EQXX is a close-to-production idea, previewing the mannequin household based mostly on its next-generation MMA platform. A few of its warmth pump tech is carried over to the Idea CLA that Mercedes showcased in 2023. The MMA will spawn into the subsequent era CLA, along with two crossovers and a station wagon.
