# Mercedes-Benz A-Class (W177)

The Mercedes-Benz A-Class (W177) is the fourth and current generation of the A-Class range of subcompact executive hatchbacks and sedans. It was launched in 2018 as the successor to the W176 A-Class, with sales commencing in March 2018. The available body styles include:
* 5-door hatchback (W177 model code)
* 4-door sedan (V177 model code)
* 4-door long wheelbase sedan (Z177, only sold in China)

## Development and launch

The W177 A-Class hatchback officially debuted at the 2018 Geneva Motor Show. It is based on the front-wheel drive MFA2 (Modular Front Architecture) platform and features front MacPherson struts, and rear torsion beam suspension, though some models are equipped with multi-link rear suspension.
In mid-2020, the production of the North American-market A-Class sedan returned to Rastatt, Germany from the COMPAS plant in Aguascalientes, Mexico to increase the production capacity of the GLB.
The vehicle received a facelift for the 2023 model year.

## Sedan (V177, Z177)

A 4-door sedan model was released in late 2018. The A-Class sedan is sold alongside the A-Class hatchback in Europe, while it marks the first time the A-Class is offered in North America but as a sedan only in the US and as both a hatchback and sedan in Canada, while in Mexico it's the first time the sedan is sold, as the hatchback has been marketed for the first and third generation before.
It is based on the Mercedes-Benz Concept A Sedan revealed at the 2017 Shanghai Motor Show and came in response to demand for a more practical alternative to the Mercedes-Benz CLA. A long-wheelbase sedan model (Z177) was also unveiled at the 2018 Auto China Show, featuring a 60 mm (2 in) longer wheelbase and is sold exclusively in China.
At its debut Daimler claimed it had the lowest aerodynamic drag of all production vehicles in the world, with a drag area below 0.49 m$^2$, depending on exact equipment, including aerodynamic wheel and tire combination, grille shutters, etc.

## Mercedes-AMG A 35 4MATIC+, A 45 4MATIC+, and A 45 S 4MATIC+

The A 35 4MATIC+ model was unveiled at the 2018 Paris Motor Show. It uses an all-wheel drive layout and has a 7-speed dual clutch AMG SpeedShift DCT transmission.
On 2 January 2019, the automobile insurance company, HUK24, accidentally revealed the information about new A 45 4MATIC+ and A 45 S 4MATIC+ AMG in its website. The engine is heavily revised M133 and renamed M139 with higher compression ratio (9.0:1 versus 8.6:1 for M133 engine) and a twin-scroll turbocharger situated behind the engine for better air flow management. There are two power levels: A 45 4MATIC+ with 310 kW (421 PS; 416 hp) and 480 N⋅m (354 lb⋅ft) and A 45 S 4MATIC+ with 310 kW (421 PS; 416 hp) and 500 N⋅m (369 lb⋅ft). At 416 hp (422 PS), the M139 engine fitted to A 45 S is the second most powerful series production four-cylinder engine with specific output of 155 kW (211 PS) per litre (or 77.5 kW per cylinder).
The Mercedes-Benz A35 arrived in North America as the 2020 model, though it was only available as a sedan variant in the US, while Canada and Mexico received both the hatchback and sedan models of the A35. In addition, Mexico also got the A45 4MATIC+ and A45 S 4MATIC+ hatchbacks.
