Mercedes says its electric concept has 620 miles of range and seats made with mushrooms

(CNN) Mercedes has unveiled a new all-electric concept car, the EQXX, that the company claims can go 620 miles on a single charge. The futuristic luxury car is also made with a host of innovative recycled and sustainable materials including mushroom fibers, ground up cacti and trash such as food scraps.

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.

Mercedes has said it intends for half its sales to be electric cars by 2025 and, by 2030, for the brand to be virtually "ready to go all electric." Mercedes referred to the EQXX as a "technology blueprint for series production." Mercedes plans to put a car with the EQXX's battery and electric motor technology, as well as some of the car's other features, into production in 2024, said Markus Schäfer, chief technology officer of Mercedes' parent company Daimler.

The Mercedes-Benz Vision EQXX concept car lacks the traditional grille seen on Mercedes cars today.

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.
