A selection of subtle enhancements are in store for the 2018 BMW 4 Series lineup, including the range-topping M4 models. In addition to gaining an edgier appearance and a tauter chassis, the list of cabin upgrades is highlighted by a move to the new iDrive 6.0 multimedia setup introduced on the 2017 BMW 5 Series. The updated BMW 4 Series made its public debut at the Geneva Motor Show.

Seen here in European trim, exterior revisions to the new 4 Series add visual presence and functionality. Up front, the lower intake on all non-M Sport versions has been reconfigured as a single opening which will be bordered by on U.S-spec models by a gloss-black surround that’s part of the standard Sport Line package. 

New lighting

Boasting a more dramatic overall shape, new Bi-LED headlamps have moved from optional to standard issue, with all models also offering an Adaptive full-LED upgrade. The rear of the new 4 Series displays a similar revamp, with revised LED taillamps that reinterpret the signature L-shape to more closely parallel that of the recast headlights set off by a sleeker lower apron. Rounding out this 2018 update are a selection of new 18-inch and 19-inch alloy wheels as well as two new high-profile colors: Snapper Rocks Blue Metallic and Sunset Orange.

Beyond new trim elements that include a leather-wrapped Sports steering wheel, high-gloss black cover on the center console storage bin and chrome and/or electroplated finishes accents, interiors on the 4 Series will introduce Midnight Blue, Cognac and Ivory White Dakota leather premium upholstery choices. Also on offer are the Luxury and M Sport Packages plus a wider selection of individual options that increase the level of personalization. The biggest news is BMW’s iDrive 6.0 multimedia system with an 8.0-inch screen. Buyers opting for the Navigation system will enjoy a new-look interface with six large, repositionable key icons. Stepping up to the Executive Package, buyers can opt for the new Multifunctional Instrument Display that provides different graphics for each of the Comfort/EcoPro/Sport/Sport+ modes. Other options on all 4 Series models now include Wireless Charging tray in the center armrest -- a feature that also includes a Wi-Fi hotspot that can handle up to 10 devices plus dual 2-amp USB charging ports in the center console -- as well as support for Apple CarPlay. 

Sharper handling

To reinforce the firm’s “Ultimate Driving Machine” reputation, BMW retuned 4 Series suspensions in base, M Sport and Adaptive M models to “greatly enhance the cars’ dynamic handling capabilities without compromise.” The Coupe and Gran Coupe’s stiffer chassis settings are complemented by more sophisticated damping technology and revised steering that reduces body roll and improves overall handling and stability. BMW also says the 2018 4 Series Convertible models will offer enhanced steering feel and better straight-line stability.

Coupe, Convertible, Gran Coupe and M4 powertrains all carry forward unchanged for 2018. The 430i/430i xDrive models are fitted with a 248-horsepower/2.0-liter TwinPower Turbo 4-cylinder while the 440i/440i xDrive variants come with a 320-horse/3.0-liter inline-6. In addition to bolder looks and upgraded suspensions, the high-intensity M4 Coupe and Convertible pack a 425-horsepower “M” version of the latter engine in standard form and while offering a Competition Package that pumps the pony count to 444. A 6-speed manual transmission is available on 4 Series Coupes, but all other base models come with an 8-speed Steptronic Sport Automatics. The M4 offers 6-speed manual or optional 7-speed dual-clutch automatic transmissions.

The 2018 BMW 4 Series family will arrive in dealers here this March. Pricing will be announced closer to the official on-sale date.
