The lightly-camouflaged prototype looks identical to the AMG A45 on sale today, except for its wide fenders. The more aggressive stance points toward another high-performance model with even more power. Our photographers claim the wide finders also hide the hatchback's wider track, giving the car a hunkered down look. Still, it's missing all of the crazy wings and vents that Black Series models are known for.
Either way, the hotter A45 should get some extra power from the current hatch's 2.0-liter turbocharged four-cylinder engine that generates 355 horsepower. The A-Class isn't sold in the United States. Mercedes is expected to redesign the model in the next few years.
