The BMW 3 Series facelift is due out in 2015, and although no spectacular changes in design are to be expected, technically the facelifted high-seller has changed a lot.
The previous top model 335i is replaced from the summer of 2015 by the BMW 340i with a new 330 hp six-cylinder engine. For this generation, BMW has no plans to offer an M340i M Performance model, but that might change in the next generation launching in 2019.
Rumors around a possible three-cylinder 3 Series have been circulating on the interwebs for quite some time now, but even though BMW originally planned for it, the decision was made to keep the four-cylinder engine as the entry-level 3 Series – at least for the current generation.
The new B47 four-cylinder diesel turbo will debut under the hood of the 318d and 320d models. The B57 six-cylinder diesel unit won’t arrive until the G11 7 Series launches, so the 330d and 335d xDrive will continue to use the N57 powerplant.
The biggest update coming with the facelift is the introduction of BMW 3 Series plug-in hybrids. Sold as BMW 330e or 328E, the hybrid uses a four-cylinder gasoline engine and an electric motor that provides a system output of 245 hp and comes with a fuel consumption of 2.1 liters per 100 kilometers.
All versions of the BMW 3 Series facelift will also benefit from a new suspension tuning, which will provide even more dynamic driving without compromising comfort. Minor updates are to be expected with optional equipment and control systems, like the full-LED headlights being optional.[Source: Bimmertoday]
