Set to complement its existing range of compact car models in a renewed sales push against premium brand competitors, the new four-door will slot into the Mercedes line-up as a rival to the likes of the Audi A3 saloon and recently unveiled BMW 1 Series saloon.
The entry-level saloon, to be powered by an extended range of four-cylinder petrol, diesel and hybrid drivetrains, has been conceived primarily to bolster Mercedes’ sales in key markets such as China and North America. However, supplier sources close to the German car maker have confirmed plans for right-hand drive production, indicating the new model will also be sold in the UK.
No official confirmation of the new Mercedes saloon model has been made by Stuttgart officials at this stage. However, Autocar has been told it could arrive in showrooms before the end of 2018 – the same year earmarked for the introduction of the fourth-generation A-Class hatchback.
Set to support both standard front- and optional four-wheel drive, the Mercedes saloon is among six models planned to be based on Mercedes' second-generation MFA platform, including successor models to the A-Class, B-Class, CLA, CLA Shooting Brake, and GLA.
The dimensions of the new A-Class saloon are shrouded in secrecy, but it is expected to stretch beyond the 4630mm length, 1780mm width and 1430mm height of the existing first-generation CLA.
By comparison, rivals such as the A3 saloon measure 4450mm in length, 1795mm in width and 1415mm in height, while the 1 Series saloon runs to 4456mm in length, 1803mm in width and 1446mm in height.
Information obtained by Autocar also confirms the A-Class saloon has been conceived to support two different wheelbases. A standard wheelbase version is expected to be sold in all markets except for China, which will receive its own long-wheelbase variant in line with other recent Mercedes saloon models, including the C- and E-Class.
Power for the new car is planned to come from the company’s latest M264 turbocharged 2.0-litre petrol and OM654 turbocharged 2.0-litre diesel engines, both of which will support new fuel-saving features, including the coast function already seen in more upmarket models from the German car maker.
