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 planning smaller Z2 roadster

It's been a few years since we heard about the BMW Z2, a compact, two-seat convertible that would slot in below the aging Z4 (shown above). Now, though, the crew at Car and Driver are back with details on the oft-rumored roadster.
The big shock for enthusiasts on this one is C/D's report that the Z2 will spin its front wheels, rather than its rears. A front-drive roadster is strange enough, but a front-drive BMW roadster? It's apparently true, though, as the new model would share its platform with the front-drive Mini and 2 Series Active Tourer rather than with the racier 228i or M235i coupes.
According to C/D, the rumored Z2 could be powered by a range of three- and four-cylinder, turbocharged engines, although it's more likely to be a four-only affair. Power should range from 160 to 230 ponies, while an M variant could arrive with 300 horsepower (that's a whole lot of power for front-wheel drive...).

Popular Science has named the winners in its Best of What's New awards, the victors coming in the categories of aerospace, automotive, engineering, entertainment, gadgets, green, hardware, health, home, recreation, security and software. The automotive category did not go wanting for lauded advancements:
Tesla Model S: the Grand Award winner for being "the standard by which all future electric vehicles will be measured."
BMW 328i: it's 2.0-liter turbocharged four-cylinder gets called out for being more powerful and frugal than the six-cylinder it replaces.
