What's New for 2016 For 2016, every 3 Series receives mild exterior styling updates and interior trim enhancements, along with a smattering of suspension and steering tweaks that are said to improve handling precision. The six-cylinder sedan gets a name change from 335i to 340i, a new engine with more output and a standard 16-speaker stereo. The ActiveHybrid 3 has been discontinued, and the 330e plug-in hybrid has taken its place. LED headlights are now available, as are automatic remote updates for the navigation system and a new Track Handling package that replaces the Dynamic Handling package. Finally, the Sport Line package is now standard on all but the 320i, though it comes without last year's M sport suspension, which is available separately.

What's New for 2017 For 2017, a new four-cylinder engine in midlevel 3 Series models results in a name change (last year's 328i is now the 330i) and a slight power bump. The M Sport package is now standard on 340i models, although the Sport or Luxury package can be substituted at no additional cost. Wireless device charging and Apple CarPlay integration are new stand-alone options, and the 3 Series' iDrive infotainment interface is upgraded to the latest version.
