A new report indicates the BMW 1-Series facelift will be introduced next month, ahead of a public debut set for March at the 2015 Geneva Motor Show.

Our friends at BMWBLOG are saying BMW will apply the Life Cycle Impulse on their entry-level model in January and among the changes will be the introduction of 1.5-liter three-cylinder engines. As expected, the motors in question are the B38 and B37 sourced from the 2-Series Active Tourer and the new MINI range and are going to power the 116i and 116d versions. The larger four-cylinder B47 diesel engine will come in the 118d with 150 HP (110 kW), 120d with 190 HP (140 kW) and 125d with more than today's 218 HP (160 kW).

Engines aside, the facelifted BMW 1-Series will also get a much needed exterior makeover which will include far more attractive headlights with optional full LED technology. The front grille is expected to decrease in size while the bumpers should also undergo some plastic surgery.

Our spies have already caught on camera a sedan version which will likely join the range a few months after the updated hatchback.
