Mercedes’ range claim for this concept vehicle is based on computer simulated testing, not actual driving, the company said. If the claim is accurate, though, the EQXX would be able to drive farther on a single charge than a Toyota Prius hybrid can travel on a full tank of gas, according to United States Environmental Protection Agency estimates. The Prius can only manage 588 miles. It’s nearly as far as the 644 miles that a diesel-powered Chevrolet Suburban can go on a 28-gallon tank of fuel. It’s also much farther than any other electric car currently available in the United States, according to the EPA.
Mercedes plans to demonstrate the car’s range in an actual driving test this spring, the company said.
The EQXX achieves its remarkable range with a battery pack that is half as large and 30% lighter than the one in the Mercedes EQS, the German automakers current fully electric sedan, while storing the same amount of energy, according to Mercedes. At 620 miles, or 1,000 kilometers, the EQXX would provide about 133 miles more driving distance on a charge than the EQS based on European range estimates for that car.
The EQXX gains those extra miles largely through efficiency, according to Mercedes. Mercedes claims the EQXX can travel more than 6 miles per kilowatt hour of electricity. That’s almost three times farther per kilowatt hour than a Tesla Model S Long Range, according to US EPA estimates. A kilowatt-hour is a unit of electrical energy stored in a car’s battery so miles per kilowatt hour is like miles per gallon for a gasoline car. The figures are much lower, though, because a…
