BMW is expected to reveal its all-new G20 3 Series compact saloon at October’s Paris motor show, but the Bavarian carmaker has given us a sneak preview of the newcomer via this teaser video and some high-quality images of a camouflaged prototype.

The existing 3 Series, like its predecessors, sets a high standard for all-round driving dynamics, and it’s expected to be no different with the upcoming 2019 model.

What we know for now is that the newbie is up to 55kg lighter than its predecessor, and the centre of gravity has been lowered by 10mm. Both these stats augur well for the car’s performance and cornering capabilities.

Underpinning the new car is a stiffer new chassis with a perfect 50:50 weight distribution over front and rear axles. Agility and precision is also said to benefit from a wider track and new axles.

Further enhancements to dynamic capabilities should come via an innovative damping system that uses lift-related dampers. BMW says they operate “continuously and progressively in relation to the respective spring travel” and this allows road imperfections to be neutralised “gently and precisely.”

While the standard suspension aims to deliver a balance between sportiness and comfort, the optional M Sport set-up is obviously biased more towards the former, as cars so equipped get 10mm reduced ride height and 18-inch lightweight wheels with mixed tyres.

According to BMW’s Head of Driving Dynamics, Peter Langen, the damping forces on the M Sport Suspension are approximately 20 higher than those on the standard suspension and this means the difference is “much more perceptible than before.” He went on to say the M suspension is now “much sportier, with more rigid bearings and stabilisers, harder springs and additional body struts.”

BMW isn’t for now saying anything about powertrains, but the company has revealed the G20 3 Series will be offered with a range of “thoroughly revised” four-cylinder petrol engines. These engines will allegedly be the most powerful four-cylinder units ever fitted in a production BMW.
