Lately, we've been hearing a lot about BMW's plans to expand its model line with more niche models like the X6 and 5 Series Gran Turismo. We've heard talks of a new X4 crossover, a 3 Series GT and even a hatchback M3. It's all a bit maddening, yes, but never fear – BMW has not forgotten about its core models, especially the all-important 3 Series sedan. After all, the four-door 3er is quite possibly the most important benchmark vehicle in the automotive marketplace. We do talk about it quite a bit.

BMW 3 Series interior spy shotOur sneaky spy photographers have just snapped this 3 Series prototype out testing on public roads, and while the exterior hasn't been altered too much from other development cars we've seen, our photogs managed to snap the 3er's reworked interior for the first time. Breathe easy, folks – it isn't too far removed from what we've come to know in the current E90 car. The dash has more sculpted lines, the steering wheel is beefier and has some more functional buttons and the center console features BMW's new remote-sized shifter.

We're still unsure as to what BMW has lurking under the hood, but we can expect the usual host of six-cylinder powertrains, both turbocharged and naturally aspirated. Of course, there's always the possibility of a four-cylinder option, too. Until we get the official word, we'll hug our current E90s and wait patiently. See the latest set of spy shots for yourself in the gallery below.
