The introduction of the new generation Mercedes-Benz A-Class opened a wide range of possibilities for the carmaker's AMG performance division. In April 2019, AMG showed the new A 35 sedan, and in July the A 45, its more powerful brother, surfaced.

With the launch of the new A 45 AMG promises a continuation of the "success story of their predecessors" by a car that features a new design, new capabilities and an engine that was described as "the world's most powerful turbocharged four-cylinder engine manufactured for series production."

The car has been shown in both the regular guise, but also as the souped-up S variant.

1Exterior design & features

Compared the A-Class it is based on, the A 45 comes with a series of unique features, some of which were never before deployed in its range. So is the case with the AMG-specific radiator grille, used for the first time on the compact class, and featuring a wider lower contour and twelve vertical louvers.

At the front, the car sports a pronounced shark nose and slim headlamps. In combination with the flat bonnet with power domes, these elements make the vehicle look hell-bent on making a great impression on the track.

From the side, the things that stand out are the wider front wings with flared wheel arches and the wider AMG side skirts. These make the A 45 look closer to the road than it actually is.

At the rear, there are the two large twin tailpipes – 82 mm in diameter, 90 mm for the S variant – slim two-piece rear light clusters, and a lip on the car's roof spoiler.

As standard, the AMG A 45 rides on 18-inch light-alloy wheels in a 10-spoke design (19-inch for the S).

2Interior design, features
and passenger space

The standard interior layout of the A-Class has changed to reflect the particularities of the AMG division.

At the front, the driver and passenger ride on contoured sport seats, dressed in a combination of black Artico man-made leather and Dinamica microfibre. Here and there, AMG highlights like double topstitching in red, red designo seat belts and the dashboard support trim in black Dinamica microfibre complete the interior look.

Optionally, the upholstery can be specified in Artico man-made leather in neva grey/black and mid-grey double topstitching.

The red and black used on the above materials are complemented by hints of yellow of various elements, and chrome.

The steering wheel is dressed in Nappa leather/Dinamica microfibre with contrasting yellow topstitching and features a yellow 12 o-clock marking.

The center console, where the touchpad and switches for the ESP, the manual transmission mode and the AMG Ride Control are located, comes in high-gloss black.

On the floor of the car, there are sports pedals in brushed stainless steel with rubber studs, black floor mats with AMG lettering, and AMG front entry sills in brushed stainless steel.


The list of high-end equipment fitted on the regular A-Class is to be found in the A 45 as well, only modified in such a way as to serve the needs of the AMG division.

Mercedes' MBUX infotainment system is at the center of the car's interaction with the driver, but this time it comes with AMG-specific displays. Two screens, one acting as the instrument cluster and the other as the infotainment screen, are fitted behind the same glass, creating the look Mercedes likes to call Widescreen Cockpit.

If that's not enough, a head-up display is offered as an option.

The AMG A 45 comes fitted with the AMG Track Pace feature, the "virtual race engineer," as the carmaker calls it. This software tracks 80 vehicle-specific data when turned on, for drivers to get a better understanding of their driving style and performance.

Track Pace comes with pre-loaded circuits – including Nürburgring or Spa Francorchamps - and is available as standard on the S version (optional on the base).


At the heart of the AMG A 45 lies a new, hand-assembled 2.0-liter engine that pumps out two different outputs, depending on the variant it is fitted on. The engine is mated to a new AMG SPEEDSHIFT DCT-8G dual-clutch transmission and the and 4MATIC+ all-wheel drive.

Compared to the previous version of the A 45, this engine develops 40 more horsepower. In the base version, that means 387 hp and 480 NM of torque, and in the S it translates to 421 hp and 500 Nm of torque.

Acceleration time for the car has been measured to be 4.0 seconds for the base and 3.9 seconds for the S. The top speed is electronically limited to 250 km/h (155 mph) and 270 km/h (167 mph), respectively.

The AMG A 45 comes with six driving modes: Slippery, Comfort, Sport, Sport +, Individual, and Race.


Besides carrying over all the features usually fitted on the A-Class, the a 45 uses an extensively reinforced bodyshell for improved handling and safety.

The reinforcement of the shell has been made with the addition of a lightweight aluminum plate under the engine, a strut tower brace between the front suspension struts and pistol-shaped shotguns, and diagonal struts at the front and rear.


Ever since the beginning of 2019, AMG has been caught up in what is sure to become its biggest model offensive ever. With about ten new models launched since, the brand is betting big on the economy, new customers and a wide range of models.

The A 45 becomes the second car in its line, following the introduction of the A 35 in April, meaning the new car comes even before it is appropriately launched on the market.

AMG seems to be under the impression an expanded lineup of cars will draw in more customers, especially ones new to the brand.

In Germany, the A 45 4MATIC+ retails from €56,227.50, and the S variant is priced at €61,820.50.
