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.

Mercedes leads in US luxury car thefts

Mercedes-Benz makes some fine automobiles. The Silver Arrow'd cars are so good, apparently, that thieves can't help but try to steal them. The German brand is at the top of the charts for luxury car thefts in the US, according to the National Insurance Crime Bureau, with New York City leading the way. (And those New Yorkers complain about Detroit being bad!)
The C-Class was the most stolen model, with 485 ganked between 2009 and 2012 in NYC alone, while the E-Class and S-Class (which also boasted the worst recovery rate, at 59 percent) both finished in the top ten. Following the C-Class was the BMW 3 Series and Infiniti G. Not surprisingly, each of these were the most common models in their respective lineups. Los Angeles and Miami are also prime hotspots for luxury car thefts, according to the Detroit News report.
While getting your car stolen is pretty awful, there was one inspiring statistic compiled by the NICB - the average recovery rate across the board was 84 percent, with the Cadillac CTS getting recovered 91 percent of the time.

BMW 2 Series Active Tourer getting third row

In what enthusiasts will likely see as a continued attempt to dilute the BMW brand, the German manufacturer is testing a three-row variant of its already controversial 2 Series Active Tourer. Our trusty spy photographers captured images of the new, front-drive MPV testing on the roads of Europe.
The easiest way to ID this more passenger friendly 2er is its slightly longer length, which will allow it to accommodate seven people in total. As our spies point out, this should make the 2AT an attractive proposition for European taxi companies. Yep, BMW built a car that will be praised by taxi drivers. On top of the extra seats, the rear overhang appears larger as well, which should mean extra cargo space.
This, of course, is not the first time we've captured images of a new 2AT variant undergoing testing. Back in May, we spotted a hybrid-powered variant out for a drive.
