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 M3 driving off cliff is a chilling PSA

We're a little shocked that the unnamed owner of this cliff-diving E46 BMW M3 would upload the in-car footage of his accident to YouTube. Not only that, he uploaded two videos: raw footage of his roll down the cliff (it looks like somewhere in the Southwest, maybe Arizona) and a tribute video for his BMW that suffered the most severe consequences of understeer. Not only does uploading the videos leave him wide open for judgment by fellow enthusiasts (just read the YouTube comments), but we imagine if the police and his insurance company somehow don't know about the incident already, they will shortly. Scroll below to view for yourself.
The raw footage shows the sort of driving that led to the M3's violent tumble, and it serves as a good public service announcement reminder for everyone out there: Just like the Spengler's streams, double yellow lines aren't meant to be crossed. Also, hard driving is one thing, but hammering on public roads at speeds clearly above your skill levels as a driver is not only a recipe for legal trouble, it's a script for ruining your car at the very least, if not your life.

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.
