The 3 Series has been freshened for 2017, receiving some suspension tweaks, updated interior touches, and a few more horsepower for the turbo four-cylinder, which gets renamed 330i. We got a respectable 26 mpg overall with all-wheel drive version. Handling has been sharpened, endowing the car with some of its lost agility. The ride is firm, yet steady and composed. The seats are comfortable and the cabin is impeccably furnished. 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 wagon, less powerful 320i, or a plug-in hybrid. The M3 can give ultra-high-performance cars a run for their money.
