The Mercedes Vision EQXX is set to be the "most efficient electric car in the world." With a claimed range at 750 miles, we can only theorize how efficient this car may be. Many factors go into buying an electric vehicle and one of which is range. Several automakers, including Tesla and Lucid, have been "range-topping" each other lately. Currently, Tesla has the longest range EV with the Model S Long Range Plus coming in at 402 miles. In the near future, Tesla plans to roll out the 520+ mile Model S Plaid and Lucid has recently announced their 517 mile Air Grand Touring.
While over 500 miles seems impressive, and possibly unnecessary, Mercedes is betting on over 750! When designing electric cars, many factors come in to play. The difficulty of developing electric vehicles is finding the "sweet spot" in terms of the perfect battery weight. Higher energy densities yield more range; in turn, the overall weight of the vehicle will increase. The more weight, the more energy will be needed to propel the car, and thus, the vehicle may become less efficient. One way to counteract the increased weight is by using lighter framework materials, like in the BMW i3. Once again, lighter materials, like carbon fiber, are significantly more expensive than conventional materials.
If we are taking guesses, the Vision EQXX should have a battery larger than that of the Lucid Air, which is already going to be extremely efficient at 113kWh. To get this efficiency, we'd expect at least over 130kWh to provide this staggering range estimate. By getting these efficiency numbers, this vehicle must have a theoretical efficiency well under 200 Wh/mile. It will undoubtedly be fascinating to see what the vehicle will look like. From the renders, it appears to take the form of a 'teardrop' design, so we assume the drag coefficient will be very low. We are thinking somewhere in the GM EV1 and Lucid Air territory (.19 and .21 Cd, respectively). The Vision EQXX will surely be a remarkable car - with an even more remarkable price tag.
