BMW has revealed the facelifted 4-series, featuring design updates and a few mechanical tweaks.

The new 4-series line-up – which encompasses the two-door Coupé and Convertible, and the four-door Gran Coupé – receives a mildly altered front end, with lightly restyled air ducts in the lower bumper featuring on both the standard Luxury and the higher-spec M-Sport variants.

Further changes have been made to the headlights – which retain the same shape as before but receive a new internal graphic similar to the one seen on the 2012 Concept 4 Series – with LEDs for both low and high beam, together with an optional adaptive LED function.

At the rear, the model also adopts styling tweaks to the lights and bumper, mimicking the changes to the front end. It also receives revised 18-inch and 19-inch alloy wheels and two new exterior colours – Snapper Rocks Blue and Sunset Orange.

The interior receives subtle changes, including a newly designed steering wheel, electroplated aluminium and chrome trim elements, high-gloss black panels and the choice of a number of different dashboard trim finishes.

BMW has also updated the navigation system for the 4-series, with the top-of-the-line Professional unit receiving a new interface with six tile-like icons, as seen on the latest 5-series.
Having already received updated petrol and diesel engines as part of a running change in international markets last year, the 4-series continues into the latter half of its planned seven-year model cycle without any significant drivetrain revisions.

Depending on the engine, the car can be specified with the choice of either a six-speed manual or eight-speed torque converter-equipped automatic gearbox. Selected models can also be ordered with xDrive four-wheel drive in place of standard rear-wheel drive.

Heading the new 4-series line-up is a reworked M4, available in both coupé and Convertible body styles. Mirroring the changes brought to standard 4-series models, it receives freshened LED headlights and tail-lights, together with a number of subtle interior upgrades.

Power for the M4 Coupé and Convertible continues to hail from BMW M division’s twin-turbocharged 3.0-litre in-line six-cylinder engine, developing 431hp in standard guise and 450hp in combination with an optional Competition Package.

The facelifted BMW 4-series will make its public debut at the Geneva motor show in March, with deliveries in international markets set to kick off in April.
