2015 BMW M3 Sedan

BMW's all-new M3 Sedan is dynamically nearly identical to its two-door M4 Coupe sibling: a stopwatch reveals that both are sub-four-second cars to 60 miles per hour, a racetrack proves that the mechanical twins are equally as adept on a road course and a full afternoon of driving on public roads demonstrates that each possesses talented everyday adaptability.
Yet after driving both BMW models back-to-back over two full days in Portugal, it's clear there are a few noticeable differences, both objective and subjective, that don't require instrument testing to reveal. All it takes is a few hours behind the wheel of both cars to conclude that one is slightly more agile, and the other a bit more twitchy. One has better outward visibility, while its counterpart is unquestionably more convenient.
It is the little things - subtleties attained through seat-of-the-pants observations - that eventually allow me to choose a favorite.

BMW says current M3 sold out, no new AWD M models planned

Car and Driver asked the head of BMW M, Friedrich Nitschke, a few questions about what the go-fast division had in mind for the future, and was rewarded with some enlightening answers. The best news to purist ears is that Nitschke said customers don't want all-wheel drive on their M cars, so it's the rear wheels alone that will propel new product into the future. If you want both an M badge and four driven wheels, it's the X5 M, X6 M and M Performance models you're looking for in the catalog.
"Mixed bag" is the phrase you're looking for regarding the other answers. Nitschke said that future M engines "at the core of their architecture" would "be closer to BMW AG engines" that are optimized for M cars, instead of following in the line of unique marvels like the V10 and naturally aspirated V8. They will keep the high redlines, however, with Nitschke saying "there is room beyond" the 7,000 rpm mark in BMW's current V8 turbos.
Managing weight will keep the same priority for M that it is for every other brand, so electrically assisted power steering is coming, as is an "unconventional" materials mix. At the smaller end of the M scale, Nitschke described three-cylinder engines as "attractive," saying that the brand can produce more than 310 horsepower from a three-pot.

BMW 2 Series to wear 230i, M240i nameplates

BMW might not be done tweaking its naming scheme quite yet. Of course, at this point, the jumble of numbers on the back of the Bavarian models has no connection to what's under the hood. So there's not much reason to stop changing the monikers now.
As Autoblog reported a few months ago, BMW is slotting upgraded, turbocharged four- and six-cylinder engines called the B48 and B58, respectively, into the 3 and 4 Series. If this happens, the 328i/428i would become the 330i/430i, and the 335i/435i would turn into the 340i/440i.
Obviously, this change hasn't happened yet, but the same member of 2Addicts, a portion of the larger Bimmerpost community has now claimed that the 228i and M235i would get the same treatment. They would become the 230i and M240i, respectively, with the new engines.
