When Mercedes-Benz launched the bonkers A 45 AMG, with its even more bonkers M133 four-cylinder engine, a lot of people out there were probably a bit let down by the fact that it was the AMG model with the lowest number of cylinders in the company's history.
Sure, the ill-fated and rather rare C 30 CDI AMG featured a five-cylinder turbodiesel, but that car had more torque than a V8-engined C 55 AMG from the era and it had its own oil-burning aficionados.
The A 45 AMG, on the other hand, has to make ends meet using a two-liter, turbocharged four-cylinder, which in AMG-speak sounds like half an engine.
As most of you know, the M133 actually is half an engine, but half of a monster four-liter V8 which will power the upcoming C 63 AMG (W205) and the AMG GT (C190), so it's all good.
With no less than 360 hp and 450 Nm (332 lb ft) of torque squeezed from a displacement of two liters with the help of a twin-scroll turbocharger, the Mercedes-Benz A 45 AMG (and its brothers, the CLA 45 AMG and GLA 45 AMG) is the most powerful production compact on the planet and also the fastest.
While those figures would sound like a very high limit to exceed for some tuners, they don't for the ECU-tuning specialists from mcchip-dkr, who offer no less than three different tuning packages for the A 45 AMG.
The Stage 2 only uses a bespoke ECU unit and sportier exhaust catalysts to make the M133 four-pot unleash 420 hp and 535 Nm (395 lb ft) of torque. While that is mighty impressive on its own, mcchip-dkr recently uploaded a dyno video of a Mercedes-Benz A 45 AMG with even better specifications.
Using the same “Stage 2” moniker for some reason – which makes us think only the exhaust and the ECU have been fiddled with – the A 45 AMG in the video below develops a healthy 436 hp and 565 Nm (417 lb ft) of torque. We don't have any performance numbers available at this time, but a naught to 100 km/h (62 mph) time of under four seconds in perfect conditions isn't out of the question.
Alex handled his first real steering wheel at the age of five (on a field) and started practicing "Scandinavian Flicks" at 14 (on non-public gravel roads). Following his time at the University of Journalism, he landed his first real job at the local franchise of Top Gear magazine a few years before Mircea (Panait). Not long after, Alex entered the New Media realm with the autoevolution.com project. Full profile
