The all-new Mercedes-AMG A 45 has been spotted undergoing testing yet again, with this mule looking a little bit different from a previous sighting. When it makes its launch debut, the A 45 will sit pretty at the top of the W177 A-Class range, where it will likely be joined by a lesser A 35 variant.

The front end still sports quite a bit of camouflage but the design of the headlamps are clear for all to see given the standard A-Class has already been revealed. The covered areas mask what is likely a sportier front bumper as well as a Panamericana grille that is also seen on other high-end AMG models like the latest 53 43 models.

More camouflage can be found in the vehicle’s rear to conceal the bumper, although the four exhaust tips can be seen. This setup differs from the small twin exhaust exits fitted on an earlier mule, and looks more appropriate for an AMG.

The rest of the car isn’t covered because it isn’t much of a mystery at this point, plus it adopts a lower stance here. Other highlights include the more prominent brakes that feature drilled discs and larger calipers, which is again, to be expected of an AMG model.

Of course, the biggest and most important concern is what is going on under the bonnet. On the current W176-based A 45, the M133 2.0 litre turbocharged four-cylinder makes 381 hp and 475 Nm of torque. Rumours indicate that the horsepower count could climb to over 400, with the 4Matic all-wheel drive system and seven-speed dual-clutch transmission being updated to match. That should bring the A 45’s output close to the formidable Audi RS3.
