BMW Vision Future Luxury arrives in Beijing dressed to the nines

Almost two weeks ago, we reported that BMW may be bringing a concept to the 2014 Beijing Motor Show that could herald a flagship 9 Series model that would be better suited to do battle with the tip-top of the Mercedes-Benz S-Class range than the current 7 Series. Well, here it is. This is the Vision Future Luxury Concept, and straight away, it looks suited to the role of ultra-luxury flagship.
In our original story, we reported that the Beijing concept would wear styling similar to the Pininfarina Gran Lusso Coupe that was shown in Villa d'Este nearly a year ago. Unlike that car, the Vision Future Luxury sports four doors, although its roofline plunges aggressively enough for it to be considered a four-door coupe. That doesn't mean it will compromise on rear-seat space, however. Judging by the length of the rear doors alone, this is a very large vehicle.
Its styling, though, is, as we reported, quite familiar. We can see the evolution of the Concours' concept's styling, with a narrower grille that still leads up into the hood. The thin headlights use BMW's Laserlight technology while retaining a shape similar to the Gran Lusso, and the lower intake is dominated by a carbon-fiber air deflector on both ends. BMW's Air Breather system can be found behind the front wheels, adding an accent along the lower portion of the doors. In back, organic LED lighting is used for the super-slim taillights.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

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.
