Imagine an all-electric sedan cruising, on a single charge, from Los Angeles to San Francisco—and back again. Or, in the case of the Mercedes-Benz Vision EQXX concept, making a record-breaking 747-mile run from the automaker’s base in Stuttgart, Germany, to the Mercedes-AMG Petronas Formula 1 team’s headquarters in Silverstone, England.

Robb Report recently had the opportunity to pilot the teardrop-shaped silver arrow around the serpentine Mercedes-Benz test track in southern Germany’s rural Immendingen region. Instead of chasing distance records, our goal was simply to evaluate this technical tour de force, which represents the automaker’s vision for all future road-going electric vehicles.
