Porsche planning back-to-basics 911 GT

With the latest 911 GT3 and GT3 RS track toys, Porsche clearly put the emphasis on outright performance. After all, if they were all about a puristic driving experience, they'd probably have manual transmissions instead of DCTs, right? Well that's just one point where the Porsche GT division's next project is tipped to depart. According to Autocar, Zuffenhausen's skunkworks are preparing a new addition to the 911 range that will put all the emphasis on the raw driving experience, even at the expense of lap times. The yet-to-be-named model is expected to do away with the second clutch in favor of one you can operate yourself, but that's not all. We're told to expect skinnier tires to make it easier to hold at the limits of adhesion, the narrowed track from the base Carrera, and the absence of large wings and other aerodynamic features. The inspiration apparently comes less from the GT3 than from the new Cayman GT4. Look for the new back-to-basics Elfen to arrive sometime next year, after the rest of the 911 range gets updated with turbo engines. Chances look good, though, that this particular model will stick with the atmospheric boxer six. Related Video:

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.

Race Recap: 2013 Petit Le Mans draws curtain on the ALMS [spoilers]

The 16th Petit Le Mans Powered By Mazda, in the final year of the American Le Mans Series presented by Tequila Patrón, was run on Saturday. Even though many of this year's championships had already been decided, the last ALMS race ever would be a 10-hour, 1,000-mile slog around Road Atlanta to get names in the record books and decide a few series trophies.
