Spy Shots: New Mercedes-Benz A25 AMG Could get More than 320-Horsepower

The people at AMG are hard at work with the development of the most potent model of the newly revealed Mercedes-Benz A-Class hatchback. Rumored to be named either the A 25 AMG or A 45 AMG, the hot hatch could make its world premiere as early as this fall at the 2012 Paris Motor Show.

Power will come from a heavily modified version of the A 250's 2.0-liter turbocharged inline-four, which is rated at 208hp (211PS). According to sources, in the AMG model, the four-cylinder unit is believed to deliver anywhere from 320hp to as much as 350-horsepower.
