BMW looking to fix i3 acceleration problem uncovered by Consumer Reports

The BMW i3 has been hailed in some quarters as the future of electric mobility, what with its innovative carbon-fiber-reinforced plastic body and commitment to sustainable materials wherever possible. The modernist little hatch is even available with a 650cc two-cylinder gas engine with 34 horsepower to act as a range-extender for those who want it. However, that optional engine might have a drawback - at least for the moment.
Consumer Reports brought the problem to light when one of its drivers was behind the wheel of an i3 using the range-extender. When the driver attempted to pass another vehicle on a rolling, two-lane road, the BMW suddenly had no power to accelerate - a scary situation. CR started examining the car and found something pretty shocking: After driving at a constant speed for a while without any regenerative braking in range-extended mode, acceleration to 60 miles per hour plummeted from about 9 seconds normally to a staggering 27 to 40 seconds in their testing.
A BMW spokesperson told CR that it knows about the problem and has a fix coming next spring that also works on current models. The upgrade includes a state of charge indicator, a warning about loss of power and uses the car's navigation to boost the battery before driving on rolling terrain. It is not clear if the severe power deficiency will also eventually result in a recall.

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.
