Shown in 2017, the four-door version of the A-Class hatchback morphed into a production model at the 2018 Beijing Auto Show. Unveiled with a slightly longer wheelbase than usual, the A-Class Sedan will soon become a global vehicle and will cross the pond to the U.S. to take on the Audi A3 Sedan. Like most Mercedes-Benz models, the standard A-Class Sedan will be followed by an AMG model. Likely to be called the AMG A45 Sedan, the beefed-up four-door will compete against the Audi RS3 Sedan, currently the only performance-rated vehicle in this niche. The AMG model is still at least a year away, but we may already know what it looks like thanks to a new rendering from X-Tomi Design.
