The 3 Series boasts commendable ride comfort, noise isolation, and interior fit and finish. The turbo four-cylinder makes the 328i quick yet returns a frugal 28 mpg overall. Handling is very capable, but isn't as sharp as past BMWs and overall the 3 Series isn't as engaging to drive as earlier versions. BMW aims to sharpen agility with steering and suspension changes for 2016. Despite some diesel clatter, the 328d gets a standout 35 mpg overall, and its 49 mpg on the highway gives it an impressive range of 735 miles. You can also choose a hybrid, wagon, and less powerful 320i. The M3 can give ultra-high-performance cars a run for their money. 2016 brings a new six-cylinder engine and a plug-in hybrid.  For 2017, the turbo four-cylinder 328i is renamed 330i and gained a few more horsepower.
