A45 AMG vs 2010 RS3 Sportback - Speedometer Acceleration Compared [Video]
That doesn't stop people from comparing it with the old 340 hp Audi RS3, which is no longer in production because it was based on the previous generation of the A3.
Until the new RS3 arrives, you can watch a not-exactly-professional side by side video comparison between a 2010 Audi RS3 and a 2013 Mercedes-Benz A 45 AMG, both accelerating from a stand still until... wait for it... 270 km/h (168 mph).
OK, we lied, the car's aren't compared side by side in this feat, but their speedometers are, with the exception that the AMG is filmed with a fish-eye lens while the Audi is from an angle, but not everything's perfect. Well, until a real comparison is made either between the two models - or, better yet, using the upcoming Audi RS3 - the following video will probably have to do.
