Mercedes-Benz VISION EQXXMercedes-Benz VISION EQXX

Mercedes electric car prototype runs more than 1,000 km

The Vision EQXX is still a prototype, but many of them will be integrated into a later series of electric cars, and this could be very interesting: in the summer of 2021 it will be talked about Mercedes debuts a concept with a real 1,000 km range, which was introduced earlier this year. And now the company has reported test results on public roads: 1000 km on a single battery charge was easily exceeded – also thanks to a small trick – and the consumption was only 8.7 kWh per 100 km.

Efficiency brings huge scope

Target consumption of less than 10 kWh makes this happen The Vision EQXX is as efficient as a conventional 1-liter car, said the Mercedes Development Board in its January presentation. The test came to less than a liter remarkably: according to Mercedes, the electric car prototype covered a total of 1,008 kilometers including the highway and mountain stages from Sindelfingen over the Alps to the Cote d’Azur, and in the end there was still 140 km of range remaining. . According to the information, the battery capacity is 100 kilowatt-hours.

With roughly the same capacity as the Tesla Model S 100D, electric car rental company nextmove had as far as the EQXX prototype in 2018, but it’s also been a real creep in the circles. The Mercedes, on the other hand, drove up to 140 km/h and up and down mountains, according to a statement on Thursday. The average speed reached 87.4 km/h compared to 38 km/h in the following fast mileage movement with the Tesla Model S.

worry about mercedes According to the information Aerodynamics, moderate weight and efficient components ensure that the Vision EQXX can easily exceed 1,000 km, even on normal roads. The electric car is wider in the front than in the back, and the already long rear part can be extended with an extendable diffuser. In addition, the car weighs only 1755 kg despite its large battery, and also thanks in particular to the light cells from CATL. According to Mercedes, the average efficiency of the powertrain consisting of the engine, transmission and power electronics is 95 percent. As a result, active cooling can usually be dispensed with.

Electric vehicle series with EQXX elements

All this would be somewhat interesting if Mercedes had not previously announced that the EQXX prototype is similar in shape and size to a production electric car due to be introduced in 2024. According to reports, it should compete less than its E-Class EQE counterpart, i.e. possibly in the C-Class and thus The part of the Tesla Model 3. Yes With the EQS, Mercedes has surpassed the Tesla Model S in terms of range (at least according to the European standard WLTP), but with a bigger battery. With a mid-tier electric vehicle, if most efficiency measures also go into mass production, this may work even with lower capacity.

This is questionable, for example, for the 117 solar cells, according to Mercedes, that are in the roof of the Vision EQXX. Apparently, they also provide power to a 12-volt battery when driving, so that they can supply additional consumers such as the navigation system without access to the drive battery. According to Mercedes, this increases range by a good 2 percent and adds an additional 25 kilometers during the long test drive.
