2014 BMW 4 Series

Because Four Is Greater Than Three
Say what you will about the name 4 Series, there is a method to BMW's madness. On one hand, it's easy enough to just buy into the logic that odd numbers are reserved for sedans and wagons, and that even numbers are reserved for coupes and convertibles. On the other hand, consider the idea that the higher numbers are used to separate the more dynamic, more engaging vehicles that use the same platform. It's that sort of separation that differentiates the 6 Series so nicely from its 5 Series roots, after all. And if we're being cynical, it also allows BMW to charge a bit more money for its lower-volume offerings.
So with the new two-door version of the 3 Series, BMW has gone the route of strengthening the dynamic virtues of its F30 chassis to create a car that's more removed from its sedan kin than one might think. And after spending some time with the new 4 Series on the roads around Lisbon, Portugal, as well as the famous Circuito do Estoril racetrack, it's increasingly clear that calling this car a 3 Series Coupe simply wouldn't be fair.

BMW i8 with 500+ horsepower in the cards?

While BMW makes plenty of machinery to keep enthusiasts interested, its most enticing models are often based on more ordinary ones. That's what made the arrival of the i8 so captivating, emerging as the first stand-alone BMW sports coupe since the M1. But if its dual purpose - trying its best to both embrace the earth and traverse it rapidly - somehow left you disappointed, the next development could prove to fix that.
According to Automobile, BMW is working on a more potent i8S model. The hardcore version of the hybrid sports car would offer more power and a stiffened chassis to make it that much more aggressive. The Bavarian automaker is reportedly still evaluating two potential powertrain options: The first would pair a 2.0-liter twin-turbo four-cylinder good for 320 horsepower to an electric motor with another 204 hp. The second would use a 3.0-liter straight six with 480 hp and an electric motor with 109 hp. Both would be mated to a nine-speed dual-clutch transmission and an integrated starter motor packing an extra 27 hp.
Either way, we'd be looking at a combined output well in excess of 500 horsepower - far more than the existing i8's 228-hp turbo three and 129-hp electric motor - dropping the 0-62 time down from 4.1 seconds to an estimated 3.5. Couple that to a more advanced carbon chassis, wider tires and other goodies, and the i8 would be transformed into a far more capable performance machine than it already is.

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.
