New record of electric range for Mercedes Vision EQXX

Mercedes Vision EQXX is again the electric car of records, in fact it still exceeds a thousand kilometers with a single battery charge. We had seen her maiden voyage from Stuttgart to Cassis last April, but today electric has raised the bar again, with a road trip of 1,202 kilometers from Stuttgart to Silverstone in the UK.

The Mercedes electric route

The car has traveled many kilometers on different routes, crossing countries, motorways, urban and state roads between Germany and France. The Vision EQXX passed the French border near Strasbourg, arriving in northern France at motorway speed to Calais, where it traveled the Eurotunnel. Continuing her journey in the UK she took the M25 around London and then stopped at the Grand Prix circuit in Brackley.

The electric car was welcomed by Formula 1 and Formula E experts who helped develop its advanced transmission. The record-breaking Mercedes then continued its journey to Silverstone, where it was greeted by special guest driver Nyck De Vries, Dutch racing driver, winner of the 2019 Formula 2 championship and World Champion in the 2020-2021 Formula E season with the Mercedes EQ team.

The Dutchman decided not to take it easy and in fact brought the vehicle to the maximum speed limit of 140 km / h on the iconic British circuit. Making the most of the opportunity, he completed 11 laps. Throughout the road trip, the Vision EQXX leveraged its innovative thermal management system to achieve an average consumption of 8.3 kWh / 100 km in the face of heavy traffic and summer temperatures. The VISION EQXX’s long-distance journeys on public roads provide research and development experts with valuable data for the ongoing development program.

“The journey continues, even further, even more efficient! Once againthe car has proven that it can easily cover more than 1,000 km with a single battery charge, this time facing a completely different set of real-world conditions. As Mercedes is committed to becoming fully electric by 2030 wherever market conditions allow, it is important to show the world what can be achieved in real terms through a combination of cutting-edge technology, teamwork and determination, ”says Markus. Schaefer, member of the Board of Directors of Mercedes Benz Group AG, Chief Technology Officer responsible for development and procurement.

The capabilities of the Vision EQXX in the real world under different conditions

In April this year, the record maiden voyage where the car covered 1,008 kilometers from Stuttgart to Cassis, on the French Mediterranean coast. With temperatures ranging from 3 to 18 degrees, it completed the journey with an energy consumption of 8.7 kWh / 100 km and a residual range upon arrival of around 140 kilometers. But once is not enough. To demonstrate the true capability of the electric, the engineering team is taking a series of road trips to test the technology behind the Vision EQXX under different conditions.

This time the car did not have to face extreme temperatures or the demanding scenarios of consumption and energy recovery of the Alps during the journey. The main challenges of this trip were summer temperatures of up to 30 degrees, combined with a greater density of traffic around in Stuttgart and in the south-east of England. However the innovative Mercedes EQXX he kept “calm” all the way thanks to his innovative thermal management system.

The high temperatures and motorway traffic made it necessary to cool the electric drive and cabin, without any significant impact on range. The multi-source heat pump has proven highly efficient in keeping the cabin temperature cool during 14 hours and 30 minutes of driving, the air conditioning ran for just over eight hours, but had little negative impact on overall energy consumption.

The development of the Mercedes EQXX

Working hand-in-hand with the Stuttgart engineering team, Formula 1 and Formula E specialists helped reduce system losses in the transmission and develop a completely new, compact and lightweight battery pack.

After a driver change, it was Adam Allsopp, Advanced Technology Director of HPP, who took the place behind the wheel for the final stage at Silverstone. And he talked about the significance of racing on the circuit that hosted the first Formula 1 TM Grand Prix in 1950: “Driving this beacon of the future of electric mobility to the place where the history of Formula 1 began is a special occasion. Completing the journey from Stuttgart to Silverstone on a single charge with even greater efficiency truly demonstrates some great advances in accelerating the technologies behind our electrification strategy. The contribution given over the years by motorsports to Mercedes Benz is significant and makes us very proud “.
