Australian site Redline published a handful of CLA images, which show the exterior and interior of the new model, before removing the post.
Set for UK delivery next June, the 2019 CLA adopts all the various developments already seen on other new Mercedes-Benz A-Class models, including a re-engineered version of its predecessor’s platform supporting both front- and four-wheel drive, and the choice of two different rear suspension systems.
Updated four-cylinder petrol and diesel engines also feature, as well as a contemporary interior boasting Mercedes' new MBUX operating system with digital instruments and touch screen infotainment functions, among a host of new equipment. A Shooting Brake estate variant will be unveiled later in the year.
Joining the recently unveiled A-Class Saloon as the second dedicated four-door model in an expanded eight-model strong compact car line-up from the German car maker, the new CLA has grown in size and is now longer than a BMW 4 Series Gran Coupe. Figures are not planned to be made official until its unveiling, but Mercedes-Benz officials confirm it is longer than the 4549mm long A-Class Saloon.
The added length is concentrated mainly within the wheelbase, providing scope for larger rear door apertures, easier access to the rear seat and improved interior packaging with greater rear legroom.
As with the first-generation CLA, it receives a coupe-like profile with a heavily curved roofline and short boot.
Aerodynamic developments include an almost completely flat undertray with various diffuser-like elements to smooth airflow at speed. Mercedes-Benz is yet to reveal details, but it is believed the new four-door comes close to matching the outstanding 0.22 Cd of its predecessor despite a larger frontal area.
The new look is a further evolution of Mercedes’ so-called ‘sensual purity’ design lineage, with smoother and fuller forms set to replace the taut surfacing treatment and heavily etched swage lines of the first-generation CLA. The design-led focus is what will distinguish the CLA from the A-Class Saloon, similar to how the larger Mercedes-Benz CLS sits alongside the Mercedes-Benz E-Class.
Recently seen prototypes also point the way to the look of the second-generation CLA Shooting Brake estate. Like its predecessor, it's expected to receive a heavily stylised appearance, with a sloping roofline and angled tailgate set to prioritise appearance over load-carrying capacity.
