BMW recalling 1 Series ActiveE over bad drivetrain housing

There are always growing pains when automakers introduce new technologies. BMW is learning this with the electric powetrain used on the 2011 BMW ActiveE. According to the National Highway Traffic Safety Administration, about half of the all-electric 1 Series coupes currently in the hands of the public are being recalled for a potential problem that could leave the cars stranded.
With 700 ActiveE models running around the US, 360 of these cars have insufficient sealing between the electric motor and transmission, which could lead to premature wear to the connection between the two, which in turn could result in a loss of propulsion. BMW started notifying affected owners by phone earlier this month.
While no automaker wants a recall on its hands, it's much better for BMW to learn such a lesson now on the low-production, lease-only ActiveE ahead of the car's successor, the BMW i3, which is expected to be a much higher-volume EV. Scroll down for the official recall notification.

Ward's announces 10 Best Engines 2015

Ward's Auto has named its 10 Best Engines for 2015, covering a range of powerplants from fuel-sippers to fire-breathers. As with past years, forced-induction reigns supreme, with seven of the ten engines featuring a turbo or supercharger. This year is slightly different, though, as two of the seven blown engines are turbocharged three-cylinder mills, from the Ford Fiesta and Mini Cooper. They're joined by the 2.0-liter turbo four from the Volvo S60, the 1.8-liter turbo four from the Volkswagen Jetta and the 2.0-liter boxer from the Subaru WRX. BMW and Chrysler were the only marques to be named to this year's list twice, with the electric motor from the i3 joining the Mini's three-pot, and the 3.0-liter turbodiesel V6 in the Ram 1500 and Jeep Grand Cherokee repping the diesel crowd, alongside a certain supercharged monster. Hyundai also took a prize with a zero-emissions powertrain, with the Tucson FCV's 100-kilowatt fuel cell making the list (apparently Ward's is quite generous with what it deems an "engine"). Rounding out the list are two Autoblog favorites, each displacing 6.2 liters, but producing their power very differently. On the one hand, Chevrolet's overhead-valve, 455-horsepower V8, found in the Corvette, makes its power the old fashioned way. And in the other corner, we have one of the most exciting engines of the year – the 707-hp, 6.2-liter, supercharged Hellcat V8, featured so prominently in the Dodge Challenger and Charger SRT Hellcat. "We spend a lot of time reading the powertrain tea leaves throughout the auto industry, and we're proud that this year's list is a microcosm of all the latest innovation coming from automakers," said Ward's Editor-in-Chief Drew Winter in a statement. "It's not just a list for enthusiasts or for environmentalists," he says. "There's something for every vehicle shopper and every budget. All the powertrains on this list deliver a first-rate driving experience," Winter added. Scroll down for the full list from Ward's, and let us know which engines you think belong and which should have been included in this year's rankings. Ward's 10 Best Engines of 2015 Announced by Penton's WardsAuto Honorees span most diverse and technically advanced engines in 21 years of recognized powertrain excellence SOUTHFIELD, Mich., Dec. 10, 2014 /PRNewswire/ -- Penton's Wards 10 Best Engines of 2015 have been announced.

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.
