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.

Porsche 911 Reimagined by Singer First Drive [w/video]

"There's still a couple hundred rpm left," coaxes the voice from the passenger seat. Though I'm wailing down a mercilessly knotted up Southern California canyon road in someone else's half-million dollar coupe, my manic pace apparently isn't sufficient for the Singer Vehicle Design rep in the right seat. On one hand, my Irish co-pilot with more than a passing resemblance to Bruce Willis is playfully ribbing me because I've been driving hard, but haven't yet hit the 4.0-liter engine's 7,200-rpm rev limiter. On the other hand, if you've never heard of an Irish bloke who doesn't drink because he's got control issues – well, now you have, because the dude's stocky paws are white knuckling the car's rain gutter like his life depends on it. Within my microcosm of itinerant auto writing some days are odder than others; this particular Monday is beginning to look like one of the weirder ones. Rolling, In My Four-Point-Oh The car in question, according to a release I've signed prior to the drive, is a "Porsche 911," a "Porsche," or a "911," but certainly not a "Singer Porsche," a "Singer 911," or any number of variants thereafter. Sigh. I suppose "Porsche 911 reimagined by Singer Vehicle Design" will suffice? Oh, legal department. Nomenclature aside, what started life as a 1990 Porsche 911 has been dismantled and rebodied with a carbon fiber skin that makes it more closely resemble a small-bumpered, wide-hipped 1960s-era 911 than it does its melted bumper donor car. According to company founder (and former Catherine Wheel vocalist) Rob Dickinson, the decision to source a 964-series 911 was based on its delicate foothold between the model's combination of heritage and drivability. "I think the 964 is in the sweet spot of having one foot in old school 911 thinking with the [semi-trailing] rear suspension, which honors every earlier 911, while having a front end which is very much of the modern era and allows the car not to feel like an antique," he tells Autoblog. The specimen I'm driving is the latest evolution of Singer's vision of the reinterpreted 911, distinguished by a 4.0-liter powerplant that's been heavily modified by Ed Pink Racing (and, in Singer tradition, the serial number matches the donor car's chassis). The Van Nuys, California-based firm knows a thing or two about high-strung Porsche mills: the tuner has a long history of rebuilding such mechanical exotica such as 917, 935, and 962 race engines.

Former Porsche boss Wiedeking won't face criminal charges over VW bid

Hedge fund managers have been suing Porsche for years now, alleging that the car company lied about its intentions during its failed attempt to take over Volkswagen, a gambit that caused them billion in losses. Over the same period, authorities in Stuttgart built a criminal case against former CEO Wendelin Wiedeking (above, left) and Chief Financial Officer Holger Härter (right), filing charges in December 2012. When those fund plaintiffs lost their most recent court case, one of the dimming lights in the dark and receding tunnel was that the criminal investigation might unearth more evidence about Porsche's actions that could help the plaintiffs in pending litigation.
Bloomberg reports that another light has gone out, though, with a Stuttgart court dismissing the market manipulation case before going to trial because, as a court spokesperson said, "there wasn't enough evidence backing up the charges." When prosecutors get the files back from the court, they have a week to decide to refile, but unless they've been sandbagging evidence that could bolster the case, the only lights at the end of the tunnel will be those welcoming Wiedeking and Härter back to the world of legally unencumbered men.
