The 100% electric prototype from Mercedes, the Vision EQXX, has just broken its own record for autonomy and efficiency, by completing a journey of over 1000 km through the Middle East with an impressive electric energy consumption of 7.4 kWh/100 km, which is equivalent to about 0.9 l/100 km in a gasoline vehicle.
This was the third long journey of the 100% electric model from Mercedes, after the two previous attempts in Europe, and the second time the sports prototype has traveled over 1000 km.
This time, the Vision EQXX traveled 1010 km connecting Riyadh in Saudi Arabia to Dubai in the United Arab Emirates, in 14 hours and 42 minutes (12 hours and 45 minutes in motion), at an average speed of about 70 km/h.
At the end of the journey, the on-board computer of the Vision EQXX confirmed that the electric model still had a range of 309 kilometers.
The goal of this third journey was to maximize efficiency in all areas and examine the system’s performance in extreme desert conditions, which can reach 34 degrees Celsius, including the vehicle’s advanced thermal management. The intelligent system kept the electric motor and the cabin cool. The air conditioning system was operational during the journey with minimal impact on energy efficiency thanks, in part, to the multi-source heat pump.
In addition, Mercedes also analyzed the performance of the Vision EQXX’s solar roof, which consists of 117 photovoltaic cells that are used to power many of the auxiliary devices, reducing the energy consumption of the high-voltage system and further improving overall efficiency. During the trip to Dubai, the system collected 1.8 kWh of solar energy, adding about 24 km to the total range.
It is worth noting that the Vision EQXX is equipped with a 204 hp electric motor, installed on the rear axle, developed with the support of the Mercedes Formula 1 team, which is powered by a 100 kWh battery with 900-volt technology.
