BMW to change model designations, further yet from actual displacement?

Once upon a time, you could look at the back of a trunk lid of a BMW and come up with a pretty fair idea of what sat under its hood. For example, a 320i was a 3 Series with a fuel-injected, 2.0-liter engine, a 328i was a 3 Series with a fuel-injected, 2.8-liter engine and a 328Ci was a two-door 3 Series with the same engine. Those were good days.
Today, though, that simplicity is dead and gone. A 328i now has a 2.0-liter engine, just like the 320i, while the simple "C" designation that was affixed to two-door models has been replaced with a "4," so we have a 428i and a 435i. It gets worse, though. A 550i uses a 4.4-liter, twin-turbocharged V8 (it should be a 544ti, although we'd be willing to hear an argument for "tti") and a 740i uses a 3.0-liter, turbocharged six-cylinder, which is the same engine found in a 535i. It's madness.
And, well, it's about to get madder, if a post on a BMW enthusiast forum is to be believed. According to f30post.com, we could see a shakeup in at least the 3 and 4 Series nomenclature, thanks to an impending refresh that will see the addition of new, turbocharged four- and six-cylinder engines, codenamed B48 and B58, respectively.

BMW M4 sheds some camouflage for latest test run

Last time we saw the upcoming BMW M4 out testing, it was heavily clad with camouflage and decidedly homely looking (as most early development mules are). But in this latest set of photos, the M3 coupe successor has started to come into its own skin, and we're seeing a shape more closely akin to that of a rendering we brought you a few months back.
Unsurprisingly, the M4 coupe looks very similar to the 4 Series Concept that BMW debuted at the Detroit Auto Show earlier this year. And while non-M version of the 4er will likely look a bit more sedate, these spy shots clearly show an aggressive front fascia, large wheels and the usual quad-exhaust rounding out the rear end.
Naturally, the M3 sedan will launch before this M4 coupe (and convertible), and powertrain details are still unclear as of this writing. We understand that the current M3's naturally aspirated V8 will be axed in favor of some sort of turbocharged six-cylinder engine, and we've heard plenty of rumors as to what, exactly, it might be, but we have yet to hear any official confirmation.

BMW recalling all 2000-06 3 Series models over airbags in US, 1.6M globally

We just can't seem to get away from recalls involving the faulty airbag inflators supplied by Takata. There are already millions of vehicles in need of repair as a result of these ever-expanding campaigns, and BMW is adding another 1.6 million worldwide. The Bavarian automaker is issuing a recall for certain 3 Series models, including 574,000 of them in the US, to replace the passenger-side, front airbag inflator.
Specifically, the campaign covers 3 Series models from the 2000 through 2006 model years built between May 1999 and August 2006. "It's only the E46" generation of cars that are affected, which are now two model revisions old, according to BMW of North America spokesperson Matt Russell, speaking to Autoblog.
These models suffer the same problem as the rest of the vehicles with the faulty inflators. It's possible for the part to rupture during airbag deployment and possibly spray shrapnel at the occupant. However, according to BMW, the automaker isn't aware of any actual cases of this happening in any of its vehicles.
