Rolls-Royce is synonymous with its V-12 engines used for their cars, but the company has announced that they're going all-electric by 2030. Due to future Rolls-Royce's not being powered by a V-12, the Sweptail is sure to become even more of an icon within Rolls-Royce's history. Also using the same eight-speed automatic transmission as the Phantom, the Sweptail can effortlessly cruise down any road, with plenty of power in hand if it's ever needed. This one-off car's purpose is to display the expert craftsmanship of the Rolls-Royce artisans. Due to this however, the performance of the Sweptail can't go unnoticed, being able to keep up with the much smaller sedans on the road today.
