The BMW 3-Series has been around for a couple of years so the company is preparing a minor facelift for the popular model.

Caught undergoing testing in Europe, the facelifted model is instantly recognizable as it appears to only feature modified bumpers and restyled air intakes.

Bigger changes are expected under the hood as previous reports have indicated there will be upgraded four- and six-cylinder engines. There could also be some new entry-level variants with the company's 1.5-liter TwinPower Turbo three-cylinder engine. We can also expect a plug-in hybrid with a TwinPower Turbo four-cylinder petrol engine, an electric motor and a lithium-ion battery.
