Mercedes is all set to replace its current-gen CLA with an all-new model which is slated to be unveiled sometime next year. The second-gen CLA will share its underpinnings with the yet-to-be unveiled A-Class hatchback and the upcoming A-Class sedan.

Details regarding the new CLA have been surfaced. The future liftback model will receive slimmer headlights and more angular taillights to give it an overall sleeker look.

The car – built on Mercedes' New Generation Compact Cars (NGCC) structure shared with the next A-class – will grow in size to offer more interior room. A Shooting Brake or estate variant is also expected to be produced, though this will likely arrive at a later date.

This will make it similar in size to the first A-class sedan due to arrive before the next CLA, toward the end of 2018. When talking to our sister publication, Autocar UK, a Mercedes spokesman suggested that the CLA’s more sporting appearance and handling would ensure it attracts a different buyer.

The spokesman cited the success of the CLS and E-class models as evidence for this trend. They said that those larger cars share a similar relationship to the CLA and A-class sedan, slotting into different segments despite some similarities in size and form.

On the inside, Mercedes will introduce a new touch-operated infotainment system, using the brand’s sixth-generation Command system. It will place a more cleanly-integrated screen into the dashtop. The car will also come available with a digital instrument cluster.

The next CLA will cherry-pick powertrains from the future A-class range. Like the current model, it will come with turbocharged four-cylinder petrol and diesel engines, producing from around 122hp to 233hp, while the range-topping AMG CLA 45 is expected to have more than 405hp.

The next A-class’ hybrid powertrain could also be offered with the CLA. The electrified system will use a 48-volt electric system for mild-hybrid properties, enhancing torque during full throttle running.

In India, Mercedes retails the CLA with petrol and diesel engines and has the range-topping, AMG-badged CLA 45 as well. The brand launched the facelift for the latter version in November last year.
