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.

Karma Automotive partners with BMW for powertrains

Now in the process of rising from the ashes of Fisker, the newly renamed Karma Automotive has announced a powertrain supply deal with BMW. Only instead of Karma providing BMW with technologies (as Tesla has for Daimler and Toyota), this deal goes the other way around. It is BMW that will be providing Karma with its powertrain components moving forward. Little in the way of specifics was disclosed regarding precisely what the supply deal will entail. However according to the statement below, it will include "high voltage battery charging systems and a wide range of hybrid and EV systems." BMW has demonstrated its competence in developing and manufacturing such components with vehicles like the i3 and i8, and ActiveHybrid versions of the 3 Series, 5 Series, and 7 Series sedans. Karma Automotive is what Chinese component manufacturer Wanxiang renamed the company formerly known as Fisker Automotive once it acquired the rights to the company and the Fisker Karma which it previously produced. The brand name, however, remained the property of Henrik Fisker's coachbuilding operation. The original Fisker Karma was powered by a 2.0-liter turbo four supplied by General Motors, with a lithium-ion battery pack from A123 systems. Karma Automotive Signs Supply Agreement With BMW COSTA MESA, Calif., Nov. 12, 2015 /PRNewswire/ -- Karma Automotive announced today that BMW has agreed to be a supplier in ensuring their vehicles are built with the highest quality automotive parts. BMW will supply Karma Automotive with their latest powertrain components, including high voltage battery charging systems and a wide range of hybrid and EV systems. Throughout automotive history, BMW has been globally recognized for engineering and manufacturing world-class products. They are a proven technology leader and renowned for conceiving and delivering groundbreaking innovations. Karma Automotive will integrate the first BMW components into its plug-in hybrid flagship vehicle, which will re-launch in 2016. The next generation of vehicles already in development will utilize more of BMW's powertrain technology. "The Wanxiang Group is giving Karma Automotive the opportunity to bring a stunning car back to the market, and the partnership with BMW and their outstanding track record is a great fit for the future," said Karma's CEO Tom Corcoran.

2015 BMW 4 Series Gran Coupe

It's hard to say what a coupe is anymore. Is it merely a car with two doors? Does it have to have an arching roofline? Do frameless windows count for anything? Can a five-door hatchback or even an SUV be a coupe? At some point in the last few years, nearly everything we thought made a coupe a coupe has been challenged by something that calls itself a coupe, but to most people isn't. Our friends at BMW have led most of this line of questioning.
The new 2015 BMW 4 Series Gran Coupe is one of the latest Bimmers to challenge the moniker (which also challenges the idea of "Gran," for that matter), and unlike some of its other "coupe" variations - we're looking at you, X6 - this one is a pretty one. The 4 Series Gran Coupe is essentially a four-door version of the 4 Series, which is itself a two-door version of the 3 Series. Huh? Wouldn't that simply make it another 3 Series? Of course, but this one is prettier, as it uses the 4's sexier body styling, with its lower nose, wider-looking stance and edgier lighting graphics. It is also technically a five-door hatchback, not a sedan per se, and it utilizes frameless side door glass, which apparently does count for something in BMW coupe-land. Significantly, the 4 Gran Coupe's wheelbase is identical to the two-door; if it was longer - as is the case with the 3 Series and 5 Series hatchbacks - that might make it a "Gran Turismo." Confused yet?
We recently got our first chance to drive the 4 Series Gran Coupe at a press launch in Spain, and while the only version we were given was a rear-drive 428i Gran Coupe with the M Sport contents, the harrowing roads around Bilbao gave us a good idea of what this car is all about from a driving dynamics standpoint. Here's some of what we found:
