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.

Sunday Drive: The future looks bright, and the present ain't bad, either

A look at the week that just passed proves that Autoblog readers love looking into the future. Spy photos of the next Porsche 911 and a mysterious Dodge Demon prototype led the way last week as some of our most popular stories. A teaser from Subaru has our appetites whetted for the next WRX, and we're intrigued by the value proposition offered by the rear-wheel-drive Kia Stinger. Long-distance motorcycle tourers went gaga over leaked images of the next Honda Gold Wing. Such intense interest comes as no surprise considering that it's the standard by which all its competitors are judged, and it looks to be getting some serious new technology in its next iteration. And finally, we can't help tooting our own horn a bit. Autoblog just launched a brand-new Car Finder tool, which, after getting a few data points to work with, offers up a perfect list of vehicles for new-car buyers.

Former Porsche CEO Wiedeking indicted over VW takeover bid

Do you recall the failed efforts by Porsche to take over Volkswagen? According to a Bloomberg report, former Porsche CEO Wendelin Wiedeking (above) and ex-CFO Holger Haerter have finally been charged with market manipulation over the exercising of options as part of the German sportscar manufacturer's ill-fated attempt to take over the much larger VW. That failed bid eventually resulted in the reverse coming true - VW swallowing Porsche.
The charges leveled by Stuttgart prosecutors come after a three-year investigation centered around allegations that Porsche execs made a concerted effort to increase the company's share in VW to 75 percent in preparation for a hostile takeover. Porsche had previously told its investors on at least five occasions that it had no intention to buy VW.
Portions of the investigation have subsided, according to prosecutors, citing an inability to prove certain improprieties with a "necessary degree of certainty." The number of charges is down to 5 from a previous 14 counts regarding "information-based market manipulation."
