134K BMW 5 Series recalled for taillight issue

BMW is voluntarily recalling 134,100 cars due to a faulty ground terminal in the taillight bulb carriers, causing the sudden failure of brake lights, turn signals and reverse lights. The recall covers 2008 through 2010 5 Series models produced between March 1, 2007 and December 31, 2009, and includes everything from the 528i to the mighty, V10-powered M5. It's unclear if this recall is limited to sedans or extends to the 5-Series Touring.
There have been no reported cases of injuries, fatalities or crashes associated with the taillight issue. BMW will be issuing recall notices to affected owners in the coming weeks, asking them to report to dealers so that the bulb carriers on the taillights can be replaced. All repairs are, naturally, free of charge. Scroll down for the official recall notice from the National Highway Traffic Safety Administration.

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.

Bimmerfest puts BMW's heritage on display and in motion

The typical Memorial Day weekend is celebrated with family and friends and plenty of food, but for thousands of BMW fans it was spent at Auto Club Speedway in Fontana, CA, for the 17th annual Bimmerfest. The event expanded significantly in the last few years with a move to the massive racetrack complex outside Los Angeles in 2016, and a second day was added this year. The celebration of the Roundel is the largest of its kind, boasting 4,000 cars and 10,000 people in attendance. There's something for just about every type of owner. For those wanting serious time behind the wheel, the oval and road course were open to hot laps, and there was the Bimmer Challenge race from Speed Ventures. An autocross course was set up in an adjacent parking lot. Those wanting to compete in less dynamic fashion had a Battle of the Bimmers car show, and the Heritage Corral and Centennial Corral put the century-long history of the brand on display. Perhaps our favorite part of the event was the BMW Fan Zone display, which showcased a few of the company's most iconic contemporary racecars. A V8-powered 2001 BMW M3 GTR and a McLaren F1 GTR sporting a BMW-developed V12 provided some fond memories of their historic on-track endeavors.
