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.

The 2014 Alpina B4 Bi-Turbo Cabrio powers up luxury and speed

The BMW specialists at Alpina know how to exploit a niche when they see one. With the BMW M4 still not technically official, it saw the need for a higher performance four-seat convertible than the 435i 'vert. Enter the new B4 Bi-Turbo Cabrio that is debuting at the Geneva Motor Show.
The European-exclusive model takes BMW's 3.0-liter, twin-turbocharged inline-6 and massages it up to 410 horsepower and 442 pound-feet of torque, which is less power but more twist than the M4 would give buyers. Alpina's tend to be built more as quick, luxurious grand tourers, and the B4 Bi-Turbo gets is no different with an adaptive sport suspension and an eight-speed automatic. Plus it wears the classic pinstripes and 21-spoke wheels that are the brand's design hallmarks.
While the added weight for the convertible means that the Cabrio takes 4.5 seconds to reach 62 miles per hour, about a half-second slower than the coupe, at the moment it is the only way to get this kind of performance in a BMW convertible. Orders for the convertible open in March in Europe and prices in Germany start at 74,800 euros ($102,878 at today's conversion rates).

BMW shows up-armored X5 concept and we can't get near it

BMW has brought a slightly different concept vehicle to the 2013 Frankfurt Motor Show. Rather than something that foreshadows a future product or a new design direction, the Munich-based manufacturer has brought an X5 that's designed to be shot at. It's called the Concept X5 Security Plus. The Concept X5 name is a bit misleading, though. It's based on the 2014 X5, while BMW already builds an armored CUV, called the X5 Security. The concept tag has to do with the "Security Plus" part.
Engineered to be compliant with VR6 security standards - the current X5 Security is for VR4 standards - the Concept X5 will quite happily shrug off direct attacks from an AK-47. Thanks to sealed joints, high-strength steel moldings, high-performance steel body panels and special, polycarbonate-coated security glass, Kalashnikov's finest, whether used as a firearm or as a melee weapon, would be useless against this X5.
Built alongside the standard X5 in BMW's Spartanburg, SC factory, the X5 is shipped to a BMW facility in Toluca, Mexico for installation of the armor and security features. The company claims this delivers a more thoroughly engineered protective solution than aftermarket retrofitting.
