BMW offering glitch fix for i3 with range extender

The BMW i3 has received quite a bit of acclaim since its release, with the electric powertrain grabbing a spot on Ward's 10 Best Engines list and the high-tech machine earning the nod as 2015 Green Car of the Year. However, Consumer Reports uncovered a vexing problem with the range-extended version of the hatchback that has plagued it until a recent software update. While CR was driving the range-extended i3 last year, it discovered that when the internal combustion engine was running during low states of charge, hard acceleration could suddenly cut back with no warning to the driver. This was especially problematic when passing. BMW knew about the issue and promised a software update in the spring. That improvement is now available. BMW spokesperson David Buchko tells Autoblog that the software update adds a percent-of-charge indicator to all models of the i3 to let drivers know just how much juice is left. For the range-extended model, it also provides a warning of possible power reduction when the charge reaches two percent. According to Consumer Reports, the revision lets the car anticipate needing more reserve power based on the topography from the navigation system, as well. For any i3 drivers who want the upgrade, they need to visit a dealer for installation, according to Buchko, but it should be come at no cost to owners. Related Video:

BMW broadens engine bolt recall to nearly half-million cars worldwide

Almost one month ago, we reported on a BMW investigation into a potentially defective bolt that lived in the company's VANOS variable valve timing system. At that point, the potential recall was seemingly limited to Chinese-market cars; the company was filing a recall application with Chinese officials.
Today, Bloomberg is reporting that the engine bolt issue has expanded into a recall for several world markets, involving some 489,000 vehicles. BMW was able to verify that report to Autoblog, while also providing a great deal more detail about the issue and vehicles affected.
The recall affects vehicles powered by N55 inline six-cylinder gasoline engines equipped with VANOS and Valvetronic technologies. 1 Series, 3 Series, 5 Series and 5 Series Gran Turismo, X3, X5, X6 and Z4 models from the 2010 to 2012 model years are included, as is the 2012 6 Series.

The BMW M760i xDrive isn't as cool as the Alpina B7

Earlier this week, BMW released what we assumed was the new pinnacle of the 7 Series range: the Alpina B7 xDrive. But then we received information about the car you see here, which still isn't a full M7, but uses the name M760i xDrive. What we're trying to figure out is, why would you get the M760i over the brand-new Alpina? Mechanically, and as far as we can tell, the only real difference between the two cars is under the hood. The M760i uses a twin-turbo 6.6-liter V12 capable of an estimated 600 horsepower at 5,500 rpm and 590 pound-feet of torque at 1,500 rpm. Thing is, the Alpina B7 also makes 600 hp and 590 lb-ft, albeit at higher points in the rev range, from a twin-turbo 4.4-liter V8. Both cars use all-wheel drive. Both cars have eight-speed automatic transmissions. But while the M760i does the 0-62 run in 3.9 seconds and tops out at an electronically limited 155 miles per hour, the Alpina does 0-60 in 3.6 seconds and runs to an unrestricted 193 mph. For all intents and purposes, the little details about interior refinement and technology are basically the same. It's a top-of-the-line 7 Series, so no matter if you're doing Alpina or M760i, you're getting the best of the best. To us, though, the Alpina represents a package that's more unique. It's certainly a bit flashier, what with its Alpina-correct 21-inch wheels, blue paint, and body kit. But put the two cars next to each other on the street and ask an unknowing pedestrian which one is top dog, and we're willing to bet they'll say Alpina every time. There's no word on pricing for either version of the 7 Series, but we expect they'll be close. The M760's engine will be more expensive, but all those Alpina upgrades certainly won't come cheap. We'll know more closer to the launch of both later this year and in early 2017. For now, read more about the M760i in the press blast below.
