Mercedes-Benz A45 AMG

We were wowed by the new Mercedes-Benz A-Class at the Geneva show earlier this year, now Mercedes has handed the hatchback to high-octane huffing in-house tuner, AMG. That means 330hp from its 2.0-litre turbocharged four-cylinder motor and a seven-speed dual-clutch gearbox. It has the BMW M135i right in its crosshairs.
