The Mercedes EQXX traveled over 1,200 km on one charge!

1,202 electric km on a single charge! This is the feat achieved by the experimental Mercedes EQXX sedan, in real conditions between Germany and England.

The Mercedes EQXX electric sedan continues to demonstrate its electric long-haul capabilities. Designed from A to Z for maximize efficiency and autonomy, this unique model now serves as a technological demonstrator and rolling laboratory for Mercedes, which continues to deploy its electric range. In mid-June, the EQXX broke its own range record, with a journey of 1,202 kmcovered in real conditions from Stuttgart to Silverstone via Reims and Calais.

1,202 km in real conditions and on the highway!

A route consisting mainly of highways, including a portion of Autobahn under construction, which forced the crew to make an unplanned detour. Above all, the average speed

of the journey is quite high: 83 km / h. As we know, electric cars are generally not very comfortable at these speeds. Indeed, the losses related to aerodynamic drag and friction in general, coupled with the short distances traveled in regeneration mode, generally make dramatically decrease battery life classic models. Worse: with the scorching temperatures of recent weeks in Europe, the crew had to turn on the air conditioning.

Once in the UK, via Reims and Calais, the crew drove the Mercedes EQXX to the Mercedes F1 Headquarters, Brackley. From there, she left to stretch her legs after a long trip to the Silverstone circuit. A lap that was done bluntly, according to Mercedes.

Consumption halved

Despite everything, Mercedes announces an average consumption of 8.3 kWh/100 km. Spectacular, when you know that the most efficient classic cars demand almost double, in the best conditions. Hence a record autonomy, with 1,202 km traveled in 14 hours and 30 minutes, and especially in a single charge. At Silverstone, works Mercedes Formula E driver Nyck de Vries was tasked with draining the battery, with the car eventually coming to a stop after a few laps in the pit lane.

Remember that to achieve these results, the Mercedes EQXX uses technologies and techniques that are still difficult to adapt to a mass market car. In addition to the very advanced aerodynamic work that gives it its particular shape, we find an experimental battery developed in collaboration with F1 engineers, but also a generous use of carbon fiber, active aerodynamics, and a special heat pump.
