Mercedes-Benz has unveiled a concept electric vehicle it claims would be able to run for more than 620 miles before needing to recharge. Engadget reports: Should it come to fruition and live up to that promise, the Vision EQXX would beat the range of the Lucid Air Dream Edition by more than 100 miles and the Tesla Model S Long Range Plus by around 220 miles. Based on the automaker's simulations, the Vision EQXX would use less than 10 kWh to travel 62 miles on public roads, delivering an efficiency of more than 6 miles per kWh. Converted into fossil fuel consumption, Mercedes says that's around the "golden figure" of 1 liter of gasoline per 62 miles. The battery is half the size of and 30 percent lighter than the one in the EQS. However, it still has a capacity of almost 100 kWh. What's more, there are ultra-thin solar panels on the roof that can add up to 25 km (15.5 miles) of range. The Vision EQXX is a lightweight car (1,750 kg or 3,858 lbs) that has been aerodynamically optimized. The automaker says that, with a drag coefficient of cd 0.17, the EV is more aerodynamic than a football (which has a cd of 0.18 to 0.2). What's more, Mercedes claims that 95 percent of battery energy is directed to the wheels. Teams from Mercedes' research and development centers worked with its Formula 1 and Formula E engineers on the concept. They harnessed digital tools to reduce waste and weight by cutting out excess material -- the wheels are made with magnesium and the brake discs are built with aluminum alloy. The Vision EQXX uses recycled and plant-based materials too. As for the interior, the Vision EQXX's infotainment system has a single 47.5-inch, mini-LED 8K screen. Like the Hyperscreen in the EQS, it spans almost the entire width of the cabin, though this is a one-piece display. The automaker worked with NAVIS Automotive Systems on a navigation system with zoom and scroll functions that include a satellite view. The "Hey Mercedes" voice assistant is integrated into the infotainment system too.
