BMW's Best 1 Series Gives Back What You Put In
Every once in a while, I find myself, despite my solitary leanings and inherent modesty, working out in some kind of class setting. The tone and tenor of these classes ranges wildly - from the quiet, follow-the-leader variety, to those with a kind of Cult of Personality man or woman calling the shots, usually with idiom-laden shouting and theatrical hair. Despite their personal variation and range of professional effectiveness, there's one common concept that most instructors bring up at some point: working with intention.
The idea, as it relates to physical fitness, is that focusing your brain on the movement at hand ­- the rate of your own breathing, or the muscle groups being worked for instance - helps to perform the act efficiently and correctly. Having spent a happy majority of the last decade in an exercise-free near-debauch, I was a bit surprised to find out that this kind of mental game really works pretty well.

BMW has a rough 100th birthday as share prices slide

BMW is 100 years old now, but falling stock prices are giving the German automaker the birthday blues. Investors are worried about the company's future outlook against luxury rivals, and the shareholders aren't happy about the recent dividend payments, either. According to The Wall Street Journal, BMW's shares dropped almost 2 percent on March 9. Investors have concerns that rivals are closing in. While BMW is in first place, it's not a commanding lead. For example, the German was first in the US luxury market last year with 346,023 deliveries. However, a Polk study found that Lexus actually earned the high-end crown in the US after looking at vehicle registrations rather than sales. BMW performed well last year, including delivering a strong 2.25 million vehicles. Net profits also jumped 10 percent to $7.05 billion, and revenue grew 15 percent, according to the WSJ. However, the shareholders wanted larger dividends after the successful year. The automaker paid out based on a percentage of earnings, but the investors expected more. BMW CEO Harald Kruger has an opportunity to get stockholders back on his side next week when he announces the automaker's new strategy. Expect technology to play a major role in that discussion, including electric vehicles and digital services. We might even see the i5 debut there, according to the WSJ. To be the automotive tech leader of the future, BMW plans to make computer programmers half of its research and development staff. The goal is to develop the most intelligent car on the road.

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.
