Ford's first electric SUV is already a game-changer. Applying the Mustang moniker to an electric SUV was a risky strategy, but the decision is paying off for Ford. For the first time, the Mach-E outsold the combustion-powered Mustang muscle car last month, but the electric SUV's latest achievement is even more impressive. To demonstrate the electric SUV's efficiency, a rear-wheel-drive Mustang Mach-E Extended Range equipped with an 88-kWh battery was driven 840 miles across the UK, starting from John O'Groats in Scotland and finishing in Land's End in Cornwall, England. During the journey, the Mustang Mach-E averaged 6.54 miles per kilowatt-hour, setting a new world record for the lowest energy consumption in an electric car.
