BMW has revealed a subtly facelifted version of the first generation 4-Series ahead of a planned public debut for the three-year-old Audi A5 and Mercedes-Benz C-Class rival at the upcoming 2017 Geneva motor show.
Set for Australian deliveries by mid-year, the new 4-Series line-up, which encompasses the two-door Coupe and Convertible as well as the four-door Gran Coupe, receives a mildly altered front end appearance with lightly restyled air ducts within the lower section of the bumper featuring on both the standard Luxury and M-Sport variants.
Further changes have been made to the headlamps, which retain the same shape as those found on earlier examples of the 4-Series but receive a new internal graphic similar to that seen on the 2012 Concept 4-Series, with new LED operation for both the low and high beam together with an optional adaptive LED function.
At the rear, the 2017-model-year 4-Series adopts mildly altered tail lamps with new graphics and full LED operation as well as a lightly restyled bumper featuring new feature lines that mimic the styling of the front air ducts as well as repositioned reflectors.
The new BMW also receives revised 18- and 19-inch alloy wheels and two new exterior colours: snapper rocks blue and sunset orange.
The changes inside are every bit as subtle as those made to the exterior. Included is a newly designed steering wheel, electroplated aluminium and chrome trim elements as well as black high gloss panels and the choice of a number of different dashboard trim finishes – all mirroring the chances already brought to the 3-Series in 2016.
BMW has also updated the navigation system for the 4-Series, with the top-of-the-line Professional unit receive 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 last year, the 4-Series continues into the latter half of its planned seven year model cycle without any significant drivetrain revisions.
Included in the new line-up is a turbocharged 2.0-litre four-cylinder petrol unit delivering 135kW in the 420i and 185kW in the 430i. It is accompanied by a turbocharged 3.0-litre in-line six-cylinder, which kicks out 240kW in the 440i.
There is also a choice of three diesel engines: a turbocharged 2.0-litre four-cylinder offering 140kW in the 420d and 165kW in the 425d as well as a turbocharged 3.0-litre in-line six-cylinder with 190kW in the 430d and 230kW in the four-wheel drive 435d xDrive.
The 4-Series Gran Coupe can also be ordered with a turbocharged 2.0-litre four-cylinder diesel developing 110kW in the 418d.
The most economical of the line-up is the 420d, which returns a claimed 4.0L/100km on the combined European consumption cycle, giving it an average CO2 emission rating of 106g/km.
Depending on the engine, the 4-Series 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 four-wheel drive xDrive in place of standard rear-wheel drive.
Heading the new 4-Series line-up is a reworked M4, which is sold in both Coupe and Convertible bodystyles. Mirroring the changes brought to standard 4-Series models, it receives freshened LED headlamps and tail lamps together with a number of subtle interior upgrades.
Power for the M4 Coupe and Convertible continues to hail from BMW M division's twin-turbocharged 3.0-litre in-line six-cylinder engine developing 317kW in standard guise and 331kW in combination with an optional Competition Package.
Since its introduction to the BMW line-up in 2013, the three-model-strong 4-Series has garnered over 400,000 sales worldwide as a successor to the earlier 3-Series Coupe and Cabriolet.
