These are the first spy pictures of the facelifted Mercedes-AMG A45, which is due to go on sale in the UK this autumn.
As part of the model's mid-life revisions, Mercedes is likely to increase the power output from the A45's turbocharged 2.0-litre four-cylinder engine to beyond the 355bhp of the current car. Mercedes will be looking to eclipse the 362bhp offered by the new Audi RS3's 2.5-litre five-cylinder turbocharged motor.
Mercedes-AMG boss Tobias Moers has already revealed to Autocar that the updated A45 will be "the most powerful again" when it goes on sale. Sources have suggested that the power upgrade could mean the A45 comes with as much as 375bhp, which will be enough to take at least 0.1sec off its 0-62mph time, bringing it down to 4.5sec. It's likely the car's top speed will remain limited to 155mph.
AMG insiders told Autocar: "We’re not going to simply rest on our laurels. We already have certain developments in store for the M133 [the internal codename for the A45’s engine] that will see us retain a competitive edge if and when our rivals do catch up.”
