New EV Prototype Leaves Range Anxiety in the Dust

Mercedes-Benz's Vision EQXX completed a record-breaking 747-mile run in May

Not long ago, a 300-mile range seemed like a healthy target for electric cars. More recently, the 520-mile (837-kilometer) Lucid Air became the world’s longest-range EV. But that record may not stand for long.

The Mercedes-Benz Vision EQXX, and its showroom-bound tech, looks to banish range anxiety for good: In April, the sleek prototype sedan completed a 621-mile (1,000-kilometer) trek through the Alps from Mercedes’ Sindelfingen facility to the Côte d'Azur in Cassis, France with battery juice to spare. It built on that feat in late May, when the prototype covered a world-beating, bladder-busting 747 miles (1,202 kilometers) in a run from Germany to the Formula One circuit in Silverstone, U.K.

New artificial versions of the neurons and synapses in the human brain are up to 1,000 times smaller than neurons and at least 10,000 times faster than biological synapses, a study now finds.

These new devices may help improve the speed at which the increasingly common and powerful artificial intelligence systems known as deep neural networks learn, researchers say.
