The Vision EQXX broke its own efficiency record after travelling from Germany to UK without recharging

Dubbed as the most efficient Mercedes-Benz ever made, the Vision EQXX just beat its own efficiency record in real-world driving with another 1,202 km journey on a single battery charge. 

Following its record-breaking maiden drive from Stuttgart to Cassis (France) in April, the research vehicle set the bar even higher, with a 1,202-kilometre road trip from Stuttgart to Silverstone in the UK.

The journey, which took 14 hours and 30 minutes to complete, saw the Vision EQXX travel at an average speed of 83 km/h. The highest speed achieved during the trip was 140 km/h. 

Waiting to greet it in Silverstone were the Formula 1 and Formula E experts who helped develop its advanced drivetrain. The Vision EQXX then carried on to Silverstone, where it was welcomed by special guest driver Nyck de Vries.

The Dutchman, who races for the Mercedes-EQ Formula E team, opted not to go easy on the research vehicle, taking it up to its maximum speed limit of 140 km/h on the iconic British race track. 

Making the most of the occasion, he completed 11 laps, using the last of the charge on the pit lane. Throughout the road trip, the Vision EQXX took advantage of 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.

According to Mercedes-Benz, the main challenges on this trip were summer temperatures of up to 30 degrees Celsius, paired with increased traffic density around Stuttgart and in the southeast of England.

Following a brief recharge, the Vision EQXX continued on its way to HPP headquarters in Brixworth 33 kilometres away for an overnight stop, refresh and full recharge in preparation for its next outing at the Goodwood Festival of Speed. 
 

Appearing at the renowned celebration of historic motorsports alongside other Mercedes icons of the past present and future, the Vision EQXX also took its turn on the famous hill climb. 

With two successful 1,000 km+ road trips under its belt, the Vision EQXX has well and truly justified its claim as the most efficient Mercedes ever built. 

But the story doesn’t end there. Work continues on the development of many Vision EQXX technologies for application in future series-production vehicles.
