There is absolutely no doubt that the Mercedes-AMG A45 is an incredible technical achievement. Tested here in face-lifted 2016 form, its 376bhp 2-litre, four-cylinder turbo motor is currently the most powerful of its kind in series production. This engine grants the A45 performance stats that best all its rivals, even the new Audi RS3.
The A45 AMG has always had a utilitarian approach to performance. It has incredible outright pace but, in terms of fun, it’s overshadowed by slower rivals. Optional variable rate dampers, have addressed the A45’s overly harsh ride, while revisions to gearbox ratios and improved shift times have made the drivetrain even more aggressive.

An ultra-powerful, compact four-wheel drive hatch is severely tempting, and some will find the A45’s mix of grip and outright pace truly intoxicating. But in a world where the likes of the Golf R exist, that simply isn’t enough. A hot hatch is as much about personality as it is performance and when a super hatch like the VW offers you both, it seems difficult to justify the huge jump in cost the A45 demands.
The optional £595 AMG Ride Control suspension is an option box worth ticking. Left with the standard springs and dampers the car is a little too stiff for public roads.
The comfort mode added by the Ride Control is a welcome addition as even the minimal roll and pitch that it affords gives the car a more engaging feeling.
Optioning ‘Dynamic Package Plus’ adds a front end limited slip diff as well as a ‘Race’ setting to the car’s dynamic select rotor. This option feels less necessary as traction is so good in the A45 as standard.
'If you like going really fast then the A45 AMG might be the car for you, but I can’t help thinking that a drivers’ car should be more nuanced than this.' Jethro Bovingdon, contributing editor.
