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 considering turbo for new GT3 RS [w/poll]

Some automakers make one hardcore version of a sports car and are done with it. Or at least they make one at a time. Think Ferrari 458 Speciale, Lamborghini Gallardo Superleggera (or Super Trofeo Stradale or Squadra Corse) or Maserati GranTurismo MC. But not Porsche. It transforms the 911 into the hard-core GT3, the even harder-core GT3 RS, the you've-got-to-be-psychotic GT2 and the do-you-have-a-death-wish GT2 RS. The RS models take things to a further extreme, but what separates GT3 from GT2 models has traditionally been the use of foced induction: GT3s are naturally aspirated, while GT2s go turbo. But that could all be about to change.
According to the rumors making their round of the webosphere, Porsche is considering using a turbocharged engine for the next GT3 RS. The reason is that, as we all know, Porsche has already pushed the 3.8-liter flat-six in the existing GT3 about as far as it can go, and then some. And buyers expect not only a more bare-bones package with the GT3 RS, but also a bit of extra power.
Given that everything seems to be going turbo these days, the move might make some measure of sense, especially if Porsche wants to avoid with the GT3 RS the spontaneous combustion issues it faced with the GT3. But we can't help but wonder why, at that point, it wouldn't just skip the GT3 RS and go straight for the GT2.

Porsche Boxster Spyder GT4 under consideration

Apparently, the Porsche Boxster Spyder will not be the ultimate example of the breed, after reports have surfaced indicating that Porsche is considering an even hotter roadster after seeing strong demand for the all-new Cayman GT4. The new lightweight Boxster was just unveiled a few weeks back at the 2015 New York Auto Show, showing a 3.8-liter flat-six, just like the Cayman GT4. It's without a number of GT4-specific components, though. According to Autocar, a Boxster Spyder GT4, if it were built, would benefit from the same 911 GT3-inspired adjustable front suspension, a unique rear suspension, GT3-spec brakes and a new aerodynamic kit. "We are looking at it right now," a source within Porsche told Autocar. "Much of the engineering has already been done for the Cayman, so we think this might be a good direction for us."
