2023 Mercedes-Benz A-class (W177, facelift 2022) Dimensions, Size & Specs

The 2023 Mercedes-Benz A-class W177 facelift has a curb weight that ranges from 1365 kg up to 1605 kg (approximately 3009 to 3538 pounds). The variation depends on the trim level, engine, and optional equipment fitted. A lighter curb weight contributes to improved agility, fuel efficiency, and acceleration, whereas the heavier models might offer added equipment and stability. Overall, this weight range ensures the A-class provides a balanced driving experience combining comfort, efficiency, and responsive handling.

The luggage capacity of the Mercedes-Benz A-class W177 facelift varies from 350 to 370 liters (12.4 to 13.1 cubic feet) with the rear seats in their upright position. When the rear seats are folded down, this capacity expands significantly to between 1190 and 1210 liters (42.0 to 42.7 cubic feet). This makes the W177 quite versatile for daily cargo needs, allowing owners to comfortably store groceries, luggage, sports gear, or larger items when needed, making it a practical hatchback for city and occasional longer trips.

Yes, the 2023 Mercedes-Benz A-class W177 facelift fits comfortably into a standard garage. Given its maximum length of 4445 mm (175.0 inches) and a width with mirrors open of 1992 mm (78.4 inches), it is compact enough for most residential garages, which typically accommodate vehicles up to about 6 meters (236 inches) in length and 2.4 meters (94.5 inches) in width. The height at its tallest is 1423 mm (56.0 inches), so vertical clearance is also ample. However, it is advisable to verify your garage dimensions against the car’s width with mirrors fully extended, especially if space is tight.

Compared to its predecessor, the Mercedes-Benz A-class W176 (produced until 2018), the W177 facelifted 2023 model is slightly longer, wider, and taller, enhancing interior space and exterior presence. The W177 measures up to 4445 mm in length compared to the W176 which was around 4359 mm, giving roughly an 8.5 cm (3.3 inch) increase. Width has increased up to 1850 mm versus the previous model's 1780 mm, nearly 7 cm (2.8 inches) wider. Height has also grown marginally. Weight is higher as well, with the W177 ranging from 1365 to 1605 kg versus the W176’s typical curb weight of around 1300 to 1500 kg. This increase reflects additional equipment, safety features, and structural reinforcements, resulting in improved comfort and safety at a slight cost of added mass.

The Mercedes-Benz A-class W177 facelift offers competitive interior space and comfort when compared with rivals such as the Audi A3 and BMW 1 Series. The A-class typically benefits from a slightly longer overall length and more modern interior packaging, allowing for good rear seat legroom and a more spacious feel up front, aided by its wide cabin. Its cargo capacity of 350 to 370 liters with rear seats up is on par or slightly above the Audi A3 (around 380 liters) and BMW 1 Series (about 380 liters), though slight differences exist depending on exact model variants. Mercedes-Benz emphasizes high-quality materials, advanced infotainment, and driver assistance systems, which enhance perceived comfort and luxury. Overall, the W177 is positioned strongly in the premium compact hatchback segment, blending space efficiency with upscale features.

The Mercedes-Benz A-class W177 facelift supports a variety of rim sizes to balance between comfort, performance, and aesthetics. Available rim sizes include 16-inch options (6.5J x 16), 17-inch (6.5J x 17), and several 18-inch sizes ranging from 7.5J to 8.5J width. Corresponding tire sizes include 205/60 R16, 205/55 R17, 225/45 R18, 235/40 R18, and 245/40 R18. Choosing larger rims with lower profile tires can enhance handling and sportier looks but may slightly reduce ride comfort. Conversely, smaller rims with higher-profile tires offer a smoother ride, better absorbing road irregularities. This variety allows owners to customize the vehicle to their preferences and driving conditions.

The maximum allowable weight (gross vehicle weight) of the 2023 Mercedes-Benz A-class W177 facelift ranges from 1920 kg to 2130 kg (approximately 4235 to 4694 pounds). This weight figure includes the vehicle's curb weight plus passengers, cargo, and any additional equipment. Considering the curb weight ranges from 1365 to 1605 kg, this leaves a payload capacity of approximately 315 to 765 kg (695 to 1687 pounds), depending on the version. With a roof load limit of 75 kg (165 lbs), the car can accommodate roof racks or carriers carefully. Understanding these limits is essential to avoid overloading, which could affect vehicle handling, braking performance, and safety.

The W177 facelifted Mercedes-Benz A-class has seen refinements in its exterior dimensions and design to improve aerodynamics and thereby fuel efficiency. The vehicle retains a compact footprint, but subtle changes such as a sleeker front grille, reshaped bumpers, and refined side profiles reduce drag. While exact drag coefficient figures may vary by model, improved airflow management helps to lower wind resistance during driving. The slightly larger width and length optimize interior space without excessively increasing frontal area, balancing comfort and efficiency. Additionally, advancements in lightweight materials contribute to better weight distribution and overall efficiency. These design tweaks help the W177 achieve better fuel economy and lower emissions compared to earlier A-class generations.

The 2023 Mercedes-Benz A-class W177 facelift is offered with a range of petrol and diesel engines as well as mild hybrid variants across different markets. Engine options vary from efficient 1.3-liter four-cylinder petrol engines to more powerful turbocharged 2.0-liter 4-cylinder setups. Some variants also feature 48V mild hybrid technology to boost efficiency and responsiveness. While the core body dimensions remain consistent, the choice of engine and additional hybrid components influence the vehicle’s curb weight, with fully equipped variants tipping the scales at up to 1605 kg (3538 lbs). Heavier powertrains bring upgrades in chassis and brakes to maintain performance and driving dynamics, ensuring the vehicle is well-balanced despite variations in mass.
