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 unveils 2016 X5 M and X6 M super CUVs

The second-generation BMW X5 M and X6 M have officially made their arrival for the speed-obsessed, crossover-loving masses that aren't willing to turn to Mercedes-AMG or Land Rover Special Operations.
While the new models retain their 4.4-liter, twin-turbocharged V8s, power has increased from 555 horsepower to 567 ponies. Torque is up more significantly, climbing from 500 pound-feet to 553 pound-feet. The extra twist is slightly less accessible, with peak grunt arriving between 2,200 and 5,000 rpm, rather than the earlier model's 1,500 to 5,650. Still, we'll take the ten percent increase in torque as a net win.
The big powertrain switch sees the old X5/6 M's six-speed automatic replaced with an eight-speed Steptronic transmission from BMW M. This new gearbox feeds power to an xDrive all-wheel-drive system that can variably shuffle up to 100 percent of power to either axle. In conjunction with the force-induced thumper under the hood, this powertrain arrangement allows both M models to hit 60 miles per hour in just four seconds. That's a mightily impressive stat in a 5,000-plus-pound vehicle.

BMW considering building 3 Series in North America

There might be even more BMWs coming from North America soon. The company recently announced plans to build a flagship crossover called the X7 at its Spartanburg, SC, factory. Now, rumors are emerging that the Bavarians might be thinking about building a second North American factory that could build its quick-selling 3 Series.
According to Bloomberg, the German luxury giant is considering several possible locations for a North American factory, including two in Mexico, that may build the 3. "We will decide this in the next months. On the North American continent, there's still potential," said BMW production boss, Harald Krueger, in an interview meant for company staff obtained by Bloomberg.
If BMW decides to open a plant in Mexico, it would be following its rival Audi, which already announced construction of a factory there. Mercedes-Benz has been rumored to be working on a deal with Nissan to build its cars South of the Border as well. Rumors of Bimmer considering Mexican production have also cropped up in the past, so it wouldn't come as a total surprise to hear it made official.
