It's well known by now that every car maker tries to build all classes, so that it covers all the market needs. Mercedes Benz doesn't withdraw from the plan.
We already know they plan to officially reveal the new A-Class in spring time, but rumors and pictures now, suggest there will be a new hot-hatch out to play.
A25 is the inside name and it's meant to go out there and play hard. To be sure that it plays by the specific rules, the shape is a 3-door hatchback, a lower body shape, featuring all sorts of organic lines. It's very obvious that this car aims directly to VW Golf.
