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.

Ruf Turbo Florio is the Turbo Targa Porsche won't sell you

Porsche offers a staggering array of 911 variants. You can get the Carrera, Carrera S, Carrera GTS, Carrera 4, Carrera 4S, Carrera 4 GTS and Turbo and Turbo S (to say nothing of the GT3 and new GT3 RS). And with few exceptions, you can get each as a coupe, cabrio or Targa. Except you can't get a Turbo Targa. The partial-convertible model tops out at the GTS. But if the one thing you really wanted was a Targa with a turbo engine, the folks over at Ruf will be glad to hook you up with the tuned version you see here. It's called the Ruf Turbo Florio, taking the latter part of its handle from the second part of the Sicilian road race where Porsche got the name for its lift-top in the first place. But Ruf's take doesn't just match the factory Turbo's output – it far exceeds it: with 621 horsepower and 608 pound-feet of torque on tap, it'll put even the 911 Turbo S (on Sport Plus overboost, no less) to shame. Plus you can get it with a six-speed manual or seven-speed DCT, driving all four wheels like the factory Turbo or just the rear set like the GT2 that Porsche doesn't even make any more. It'll top out at 205 miles per hour, and all the while with the wind in your hair – but not too much of it. Related Video:
