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.

Alpina D3 Bi-Turbo torquing its way toward Frankfurt

Few tuners benefit from the kind of factory support that Alpina does, giving the pseudo-aftermarket firm nearly as much official status as BMW's own M division. And this is its latest product.
Set to debut, as expected, at the Frankfurt Motor Show this week is the new Alpina D3 Bi-Turbo, which you can consider, for all intents and purposes, the diesel M3 that BMW never built. While the outgoing D3 (which was Alpina's best-selling model) used a four-cylinder engine, Autocar reports that the new model packs a 3.0-liter, twin-turbo inline-six diesel to drive a respectable 345 horsepower but a mammoth 516 pound-feet of torque to either the rear wheels or all four through the optional availability of xDrive. (European buyers will also be able to choose between sedan and wagon bodystyles.)
The engine is the same as you'd find in the XD3 and D5 (Alpina's diesel performance versions of the X3 and 5 Series, respectively), but in the lighter 3 Series form can propel the D3 Bi-Turbo up to 62 miles per hour in 4.6 seconds and on to an Autobahn-crunching top speed of 173 mph. And as per Alpina tradition, visual cues are minimal, with a subtly optimized aero kit and 19- or available 20-inch alloy wheels. Unfortunately, the 7 Series-based B7 is the only Alpina we get on this side of the Atlantic, but an oil-drenched performance enthusiast can dream.

BMW CS reinterpretation proves retro can be sexy [w/video]

Designer David Obendorfer doesn't work for BMW, but perhaps the German automaker should give him a call. His CS Vintage Concept shows a singular ability to understand the brand's classic style and reinterpret it for today. He isn't some amateur, either. Obendorfer has an industrial design degree and has been penning the interiors and exteriors of yachts from the Officina Italiana Design for five years, which counts luxury shipbuilders like Riva and Sanlorenzo among its clients. His website shows a real passion and knack for modernizing '60s and '70s European cars, too.
Obendorfer prefers to reimagine classic automotive styles. "Retro cars are not copies of their predecessors or renovated specimens, rather they are carefully studied reconsiderations, strongly rooted in contemporary style," he tells Autoblog. For the CS Vintage Concept, he worked to update the looks of the seminal BMW 2000CS and its E9 chassis while placing them on a modern platform. Obendorfer's inspiration comes from his belief that the later CS models' design is partially responsible for defining BMW styling, with its shark-nose front and four round headlights.
The CS Vintage Concept's shape starts with a jutting hood and a quartet of LED headlights, but the whole design really comes together in profile. The Hofmeister Kink at the rear pillar with the BMW Roundel is a nice nod to the originals, yet the proportions still find the perfect fusion of classic and modern. The interior is minimalist, with a vast expanse of wood for the dashboard at first glance, but the latter opens to expose the car's infotainment system.
