Usually when people think about Mercedes AMG models, they automatically think of a large, powerful vehicle, but these people will be surprised to hear that Mercedes also plans on adding this speedy package to smaller cars like the A-Class and B-Class. The standard A-Class still has a little bit before its debut, but the B-Class has already been unveiled, and the next step is an AMG version for it.This future car, rumored to be called the 25 AMG, has already been caught testing and features the same exterior treatment previously shown on the A25 AMG. In fact, the two cars will be built on the same platform and will both be powered by a 2.0 liter turbo engine delivering somewhere between 320-350 HP. The power will be sent to all four wheels via a dual-clutch transmission.Compared to the standard B-Class model, the future B25 AMG will be distinguished by a different front bumper with bigger air intakes, a different rear bumper with a diffuser, larger wheels combined with larger brakes, and the usual AMG package.
