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 4 Series Gran Coupe caught again

It's been a while since we've seen the upcoming BMW 4 Series Gran Coupe out testing, but we're sort of inclined to ask "Why?" yet again. After all, the 4 Series is what the new 3 Series-based coupes and convertibles will be called, so the idea of another four-door version just sort of seems redundant. In other words, just how different will a 4 Series Gran Coupe be from a 3 Series sedan, aside from perhaps a more rakish roofline or a four-passenger seating configuration? Probably not much, but BMW clearly thinks it can use the additional bodystyle to rake in some extra profits.
Anyway, back to these spy shots. No more of the 4GC's skin has been revealed since the last time we saw it, but we fully expect it to share a lot of its design DNA with the 3 Series sedan, not to mention the attractive 4 Series coupe concept that bowed at this year's Detroit Auto Show.
Powertrain options should carry over direct from the 3 Series line, so we expect to see 428i and 435i models on hand, packing turbocharged four- and six-cylinder engines, respectively. We're sure that BMW's xDrive all-wheel drive will be available, and who knows, we could even get a 428d version with the new 2.0-liter turbodiesel four that debuted in the 328d at the New York Auto Show last week, or even an M4 variant.

BMW 4 Series Gran Coupe caught without cladding

Like it or not, the majority of BMW 3 Series variants are on their way out, and the 4 Series models are hotly embroiled in the testing needed to replace them. We've now driven the basic 4 Series, seen spy photographs of the 4 Series Convertible and both versions of the M4 and today we get a better-than-ever look at the 4 Series Gran Coupe.
And, mostly dependent on your personal disposition towards four-dour coupes, that look should be a pleasant thing. The long, swooping Gran Coupe may be roughly similar in size to the related 3 Series GT, but it has been sculpted with beauty in mind rather than crossover function. We expect that those details still hidden by the body cladding here, mostly front and rear, can be filled in by simply remembering what the standard 4 Series looks like and squinting your eyes a bit. Subtlety is thy name, BMW variants.
As for the mechanicals, well, we expect to have the very same greasy bits under the hood and beneath the car that are found in the 4 Series lineup, too.
