For some, if developing electric vehicles that can go 1,000km in one go without needing to recharge won’t work, the Mercedes manufacturer has done just that. The firm says it demonstrates progress in electric powertrains and sets a new average consumption record.
Didn’t use the entire vehicle range
In 2015, the giant Tesla promised its vehicles a range of up to 1,200 km by 2020. Frankly, nothing came of it, and a few weeks ago, Elon Musk pointed out that no one really needs a car that can go. thousand miles on a single charge. He then explained that such autonomy would come with some disadvantages as follows. reduced vehicle use, acceleration and efficiency. Also, the need to install a larger battery is just as much of a question mark.
As Electrek points out in an April 13, 2022 article, German manufacturer Mercedes can only 1,000 km on a single charge With Vision EQXX. The car began its journey in Sindelfingen (Germany) before crossing the Swiss Alps and then northern Italy, with its final destination in the town of Cassis on the Côte d’Azur. In total, the trip will be required 11 hours 32 minutes drive.
The manufacturer stated that the journey starts in cold and rain on sections of the highway that are limited to 140 km/h. When it arrives, the battery still contained 15% of its reserve in energy. Thus, the vehicle traveled 1,000 km (exactly 1,008 km) and could still travel approximately 150 additional km.
A new average fuel consumption record
“We demonstrated the effectiveness of our project with our successful trip to the south of France. But this success clearly demonstrates the success of our new collaborative development process, which brings together the many lessons learned from the Mercedes-AMG F1 team and its cutting-edge expertise in electric powertrains.”Can we read it in a press release?
For Mercedes, the experiment is a success, and the battery is not the only reason. It must be said that the Vision EQXX benefits from very efficient aerodynamics, leaving almost no wind resistance. In addition, the vehicle is equipped with special tires with very low rolling resistance. According to the manufacturer, the average fuel consumption during this trip set a new record: 8.7 kWh per 100 km.
In addition, the Vision EQXX has a solar roof (117 cells) that provides 12 V batteries to power auxiliary consumers such as the navigation system. We’re talking about a “solar booster” here with a 25km benefit on the total trip, ie. 2% of total autonomy.
