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.

1971 BMW 2002 is a car designer's car

Choosing what car to buy, drive, and love is a difficult decision for anyone. But when you're a car designer, the decision carries that much more weight. Then again, it may be that much easier when your whole decision comes down to the visceral and the aesthetic. Take Radu Muntean, for example, who's profiled in this episode of Petrolicious. Not to be confused with the film director of the same name (and nationality), this Radu Muntean is a car designer by trade. Since moving from his native Romania and graduating from the Art Center College of Design in Pasadena, Radu went on to work for the likes of Ford, GM, and Tesla. But his pride and joy is a set of wheels he didn't design himself: it's a 1971 BMW 2002. It's a model that BMW made for the long stretch of time in the 1960s and '70s, and enjoys a cult following to this day. And it's not hard to see why. Radu has customized his vintage Bimmer extensively, but rather than glitzing it up, he's boiled it down to its essence. And like a Lancia Fulvia or Alfa Romeo Giulia of the same era, this 2002 is a thing of simple beauty: squared-off design, slap sides, tall greenhouse, and little more. Related Video:

BMW 5 Series wagon makes incognito grocery run by way of the 'Ring

With a debut in 2009, it's high time that BMW delivered the world with the standard mid-cycle refresh of its popular 5 Series. While we aren't expecting to see it here in the United States, that freshening will include the vehicle shown above, the 5 Series wagon.
This is only the second time we've spotted the camo'd, long-roof 5er in the past year, and while it was chained to a flat-bed in those snaps, today, we can see it lapping the Nürburgring. In addition to the images from the track, we also have our first look at the cabin of the freshened 5 Series, although even it is covered in camouflage, making it quite difficult to spot anything of substance.
As for the exterior, expect modest changes for the second-half of the F10 5er's life, with typical tweaks like new headlights and taillights, and perhaps a freshened front fascia. Considering we last saw the upcoming 5 Series just over a year ago, we'd expect an auto show debut for this smoothed-over model in the not-so-distant future, with Paris a leading candidate.
