Mercedes has used all of its resources, including F1 know-how, to develop an electric sedan with world-leading specs.\r\n
, and on Monday the automaker unveiled the Vision EQXX concept car to demonstrate its leadership and capabilities when it comes to electric-vehicle technology.
Mercedes started development of the EQXX with the goal of rethinking every element of an electrically powered vehicle in order to maximize efficiency. The result, the automaker claims, is a car that can cover 1,000 kilometers of real-world driving on a single charge, or about 100 miles more than the current range king, theThe EQXX is a sedan that weighs approximately 3,858 pounds, has a wheelbase of 110 inches, generates a peak 201 hp, and runs on a 900-volt electrical system.
Mercedes tapped all of its various divisions to help maximize the car's efficiency, including the Formula One team. This extends to the software used by the car. Other key efficiency areas include the design of the electric motors, the use of lightweight materials, and the optimization of aerodynamics.In the case of aero, we're talking a coefficient of drag of about 0.17, thus beating the 0.20 Cd rating of the—which has the lowest rating for a production vehicle.
Another key area is heat management. A system of aero-shutters, coolant valves and water pumps helps keep the drive unit and battery from overheating. Conversely, when conditions are cold, which normally reduces range, the system can help preserve heat. A heat pump is also present to help draw heat from the drive system for keeping the cabin warm. It also features an external heat exchanger that draws heat from the ambient air to help warm up the cabin faster.
Weight reduction was achieved via the increased use of lightweight materials. However, there was also a new technique employed for some structural elements, where software tools were used to design parts with high-strength, low-material characteristics, resulting in somewhat organic-looking forms. We've seen something similar from companies like
