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.

2015 BMW X4 gets its small-screen debut

It's easy to dismiss the 2015 BMW X4. On one hand, the high-style crossover seems more like a boardroom decision than a practical one. In a world with the 3 Series, 4 Series, X3, 3 Series GT and 4 Series Gran Coupe, is BMW really being inundated with requests for a baby X6? Of course, when we finally got behind the wheel of the CUV for our First Drive, it proved rather entertaining, and certainly the X6's global sales success suggests that it's worth the relatively low-cost risk for the Bavarian automaker.
Now, it's the general public's chance to weigh in on the latest crossover Bimmer and vote with their dollars. The X4 is just hitting showrooms in the US, and BMW is beginning its marketing campaign for it with the slogan "Embrace the Unknown." The first TV ad shows off the CUV driving through the world's major cities as they undulate like the rolling ocean. A woman flatly says phrases starting with "Go," while a synth-heavy score plays underneath that wouldn't be out of place over the end credits in an '80s sci-fi movie.
Visually, it's actually kind of a cool ad and evokes some of the special effects from Inception. Focusing on an urban atmosphere is probably a good idea, too, because the percentage of X4s going offroad is likely to be in the low single digits, if that. Now, let's see if BMW buyers are willing to embrace the unknown of the X4. Scroll down to watch it for yourself.

BMW i8 Spyder gets production nod

BMW could be poised to expand its i8 range, beyond the hardtop version of the plug-in hybrid supercar. A report from Bimmerpost is claiming that the i8 Spyder, which we showed you in concept form at the 2012 Beijing Motor Show, will be heading to production.
The website claims the open-roof fuel-sipper was shown to BMW management last Friday as a production-intent model. Other than that, there's not a lot to tell here. The i8 Spyder should feature all the same mechanical and aesthetic features found on the i8 Coupe, just without the confining nature of a roof. It's unclear when we'll see a production i8 droptop make its debut, although this certainly strikes us as the kind of car that should arrive at the Geneva Motor Show.
While an i8 Spyder does seem like a logical leap for BMW's i sub-brand, we're going to keep this one filed under the rumors category until we hear more.
