At the beginning of the year, Mercedes unveiled their radical electric concept car, the Vision EQXX, which would handle over 100 miles on a single charge. Now it has been shown that it is possible.
The journey left Sindelfingen across the Alps, through northern Italy and up to the destination Cassis in France. The driving was done at “normal speed” and on the autobahn you were sometimes at a full 140 km / h.
Mercedes says, however, that it was “close to the speed limit” in the other places. Which suggests that you might have driven a little slower than the average Swedish son. However, the average speed of 87.4 km / h shows that the progress was not particularly slow.
The result is very impressive in any case. Consumption landed at an incredibly low 8.7 kWh / 100 km. The slowest load in our 75-mile race with an electric car was the Tesla Model Y at 19.5 kWh / 100 km. Last year, the Model 3 was the one that pulled the least with a consumption of 17.4.
To ensure that everything went right, the charging socket was sealed and an independent expert from TÜV Süd was on the trip.
Could drive even further
In the finish, the car had driven 1,008 km and then had around 15 percent left in the battery. So about 140 km more would have been possible without having to charge.
The high efficiency is possible due to a low air resistance. Mercedes EQXX has a Cdvalue of 0.17. We can compare this with the updated Model S, which according to Elon Musk has a C.dvalue of 0.208.
The EQXX is also very light to be a modern car. 1,755 kg makes it about 150 kilos lighter than a fully internal combustion engine BMW M3.
The battery is large and has a capacity of 100 kWh. Or yes, big was perhaps the wrong word as Mercedes boasts that they are 50 percent smaller than the battery pack in EQS, which, however, has a slightly higher energy capacity.
Carbon fiber and aluminum are of course used a lot on EQXX to keep the weight down.
The technology in EQXX, as we wrote more about earlier, will appear in the next generation of electric cars from Mercedes in about three years.
100 miles is still too little!
