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.

Updated BMW X6 spied running the 'Ring in Germany

Following the debut of the X5 earlier this year, it shouldn't come as a shock that BMW is testing an updated X6 in its homeland. The Munich-based manufacturer trekked to the Nürburgring to test the lifted, four-door coupe it calls a Sports Activity Vehicle, while also giving us our first peak as to what the future holds for one of the weirder models in the brand's stable.
Mainly, we can safely expect the next X6 to get the same range of refinements made to its platform-mate, the X5, which debuted earlier this year. If we're lucky, that could mean an X6 sDrive35i, complete with rear-wheel drive with which to fling the big SAV about. Adding a rear-drive option could also broaden its admittedly limited appeal by lowering the cost of entry, which could serve the pricier X6 well. As a point of reference, the X5 sDrive35i is priced at $2,300 below an xDrive all-wheel-drive-equipped model.
The X6's top-flight xDrive50i model should get the same 45-horsepower bump as the X5 xDrive50i, thanks to refinements to its twin-turbocharged, 4.4-liter V8, while the 3.0-liter, turbocharged six-pot should remain unchanged. We wouldn't hold our breath for an X6 diesel to arrive, although weirder stuff has happened. Like the X5, though, this should be a pretty slim refit that improves an already competent package to go along with an expected increase in price.

BMW i8's three-cylinder sounds like it's shaping up quite nicely

We've run across some rather interesting news... or perhaps we should say interesting sounds. The folks from Bimmerpost have scrounged up a short video showing a preproduction BMW i8 running through a few gears in Sport mode at a quick pace, and if you were concerned that the somewhat eco-friendly nature of the upcoming German sports car would neuter its ability to stir the aural senses, fret not.
Judging by the lovely noise coming from the engine compartment of the i8 in the video, BMW's expertise in tuning high-strung, small-bore engines - remember, BMW Motorrad has quite the penchant for well-conceived motorcycle engines - has come through loud and clear. Now, it's worth mentioning that BMW's controversial Active Sound technology will be included with the i8, so the production car may not sound exactly like this version, which is running with the tech disabled. Owners won't have the ability to disable Active Sound on production i8s.
In related news, Bimmerpost reports that BMW will equip the i8 with an external Active Sound Design system to go along with its Pedestrian Protection System. That means those on the outside will likely hear piped engine recordings from the rear and a sort of "howl" from the front in order to warn pedestrians that the otherwise quiet (when running on electricity, that is) car is approaching. It will also feature technology that can stop the car before contacting a pedestrian.
