All-new sedan scheduled for public debut on October 2.

The next-generation BMW 3 Series will be unveiled at the Paris motor show next week – the company has confirmed.

At a press conference scheduled for 9:00am CET (5:00pm AEST) on Tuesday, October 2, the Bavarian marque will reveal the seventh iteration of its popular sports sedan, headlining its stand at the event.

No further details were added, but a series of teasers over the past couple of months have given us a good idea of what to expect from next week's announcement.

BMW claims the new 3er will maintain its 50/50 weight distribution, and have a centre of gravity around 10mm lower than the current car. Its new CLAR platform (shared with the larger 5 Series and 7 Series) also means it'll be 55kg lighter on average.

The company has also revealed the body will be more rigid, the tracks will be wider, and the wheels will have more camber – all claimed to deliver a more engaging and sharper drive than the vehicle currently on sale.

We also know the new 3 Series will be offered with 'the most powerful four-cylinder engine ever to be fitted in a BMW series-production model', which we believe will be a version of the 225kW/450Nm 2.0-litre turbo four that recently debuted in the X2 M35i.

An eight-speed automatic will be offered across the range – we're unsure if a six-speed manual will continue to be available as an option – while fuel consumption savings of 5.0 per cent are also being claimed.

There'll also be a new "lift-related" damping system, standard across the range, designed to deliver better body control in a range of conditions.

We're also expecting the new-gen 3 Series to get an interior and technology overhaul, including a more premium cabin design inspired by the 5 Series and X3 with higher-quality materials, along with the BMW OS7.0 software incorporating a wide-screen central display complemented by the option of an all-digital instrument binnacle.

Rounding out the upgrades should be BMW's latest and greatest driver assistance systems and active safety technologies, to better take the fight to the likes of the Audi A4 and Mercedes-Benz C-Class, which will likely include semi-autonomous driving capability.
