BMW 3 Series 2019 enters production

BMW'S seventh-generation 3 Series has hit production before its official debut at next month's Paris motor show, with the brand releasing a short video showing the new model's construction.

Although little is known about the new premium mid-sizer that will take on the likes of the Mercedes-Benz C-Class and Audi A4, BMW has already revealed that a variant – likely the mid-spec 330i – will be powered by the brand's most powerful four-cylinder engine yet.

Outputs will exceed the current benchmark of 180kW/350Nm found in turbocharged 2.0-litre petrol 330i model, and will likely match the new-generation Z4's 190kW/400Nm engine in mid-tier 30i guise.

Also expect to see an entry-level 320i petrol version, which could borrow from the Z4's base 145kW/320Nm to lift outputs by 10kW/50Nm, but it remains unclear if BMW will bring to market another diesel-powered 320d.

Likely to once again top the standard 3 Series range – until the hardcore new-generation M3 is revealed down the line – is a 340i, with outputs this time expected to lift 10kW/50Nm to 250kW/500Nm from a turbocharged 3.0-litre inline six-cylinder petrol engine.

The new-gen 3 Series is said to improve fuel efficiency by as much as five per cent.

Mated to an eight-speed ZF torque converter automatic transmission, the new-gen 3 Series is said to improve fuel efficiency by as much as five per cent, while a petrol particulate filter will also help BMW's volume seller meet Europe's more stringent Worldwide Harmonised Light Duty Vehicles Test Procedure (WLTP).

Aside from the drivetrain, the new-gen 3 Series will drop its centre of gravity by 10mm and gain perfect 50/50 weight distribution in its bid to be the most driver-focused premium mid-sizer.

Weight is also down by around 55kg compared with the current model, while new 'lift-related dampers' are also fitted as standard across the range to reduce noise, vibration and harshness levels.

Although current versions of the BMW 3 Series are sourced from South Africa, the new-generation mid-sizer will be sourced from Germany.

Full details will be revealed next week at the Paris motor show.
