Charged EVs | Mercedes VISION EQXX makes 747-mile street journey from Germany to England on a single cost


The Mercedes-Benz VISION EQXX, a analysis car designed for max effectivity, demonstrated its 1,000 km+ vary on a street journey from Stuttgart to Cassis, France in April. Now the check automotive has cracked the thousand-kilometer mark once more, driving 747 miles on a single cost on its method to the current Goodwood Competition of Pace in Silverstone, England. Beginning in Stuttgart, the VISION EQXX cruised throughout France to Calais, handed by the Eurotunnel, and arrived at Goodwood, the place Formulation E driver Nyck de Vries took it for just a few scorching laps on the long-lasting British race observe at its most pace of 87 mph.

The purpose of the odyssey, which featured freeway driving, heavy site visitors and temperatures of as much as 86° F, was to show the effectiveness of Mercedes-Benz’s thermal administration system and different effectivity applied sciences in a spread of real-life site visitors situations, and to offer the automaker’s R&D workforce with knowledge for the continuing growth program. On this journey, the VISION EQXX achieved a mean consumption of 8.3 kWh/100 km. (For comparability, a Tesla Mannequin 3 Rear-Wheel Drive, which is likely one of the best manufacturing EVs, achieves 14.9 kWh/100 km.)

The analysis car’s excessive effectivity has a lot to do with superior thermal administration. In response to Mercedes, “The distinctive effectivity of the electrical drive unit means it generates solely minimal waste warmth. This helps hold the thermal administration system extraordinarily small and light-weight. The rigorously engineered interplay of aero-shutters, coolant valves and pumps ensures the electrical drive unit maintains essentially the most environment friendly temperature steadiness at minimal power value. It encompasses a mixture of progressive air-flow administration and a cooling plate put in within the car flooring, enabling it to make the most of the air flowing alongside the underside of the VISION EQXX. That is essentially the most aerodynamically environment friendly means of protecting the electrical drive unit cool below regular situations, permitting a rise in vary of round two p.c in essentially the most aerodynamic mode.”

“The multi-source warmth pump within the VISION EQXX proved extremely environment friendly at protecting the cabin temperature cool within the heat summer time climate,” Mercedes explains. “In the course of the 14 hours and half-hour of driving time, the air con was operational for simply over eight hours, but had a minimal destructive affect on general power consumption.”

“But once more, the VISION EQXX has confirmed that it could simply cowl greater than 1,000 km on a single battery cost, this time confronted with an entire completely different set of real- world situations,” mentioned Mercedes-Benz Group Board Member Markus Schäfer. “As Mercedes-Benz strives to go all-electric by 2030 wherever market situations enable, you will need to present to the world what could be achieved in actual phrases by a mixture of cutting-edge expertise, teamwork and dedication.”
