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 944 Turbo jumps in the MotorWeek wayback machine

While there's no shortage of five- or ten-minute time wasters on the Internet, we humbly submit MotorWeek's awesome series of retro reviews as the best way to take up a short break. This time around, we have a classic Porsche from the 1980s, with John Davis reviewing the 944 Turbo. With a whopping 247 horsepower, the 944 Turbo still represents something of a performer even today, with Davis and Company recording a solid 5.7-second sprint to 60. While it might hold its own against today's hot hatchbacks, it's clear that today's vehicles have come a very long way in terms of interior equipment. Among the things MotorWeek highlights that seem weirdly out of place today include the passenger front airbag and, among the variety of old fashioned controls scattered throughout he cabin, the hilarious equalizer controls for the 10-speaker Blaupunkt stereo.

Mark Webber hospitalized as Porsche takes first WEC victory, Toyota wins championship [UPDATE]

It was a mixed bag for the Porsche team at the 6 Hours of Sao Paulo this weekend – the last race of its first season in the FIA World Endurance Championship. On the one hand, the German team took its first win since launching its LMP1 effort at the start of this season. On the other, its star driver suffered a massive crash that left him in the hospital. The crash occurred with less than half an hour to go when Mark Webber, who was running sixth in the #20 Porsche 919 Hybrid, lost control at Turn 14 at the Interlagos circuit – the same spot where he crashed his Jaguar F1 car during the 2003 Brazilian Grand Prix – and crashed tail-first into the barrier. Both Webber and Matteo Cressoni (driver of the #90 Ferrari 458 Italia with which Webber collided) were evacuated to the trackside medical center and were then taken to the nearby Hospital Bandeirantes. Both were reportedly conscious throughout but are undergoing further testing, described as being in "satisfactory" condition by the FIA medical official on the scene. The occurrence of the crash so close to the end of the race, and the time it took to clear the wreckage, meant there was not enough time for a restart, so the race was completed under the safety car. But when the field did cross the finish line, it was the #14 Porsche 919 Hybrid driven by Romain Dumas, Neel Jani and Mark Lieb that took the checkered flag – marking the first time that Porsche has won an endurance prototype race since 1989. Of course, that solitary victory was not enough for Porsche to take the title, which went to the Toyota TS 040 driven by former F1 drivers Sebastien Buemi and Anthony Davidson, who finished the race in second place ahead of the Audi R18 E-Tron Quattro driven by the retiring Tom Kristensen and his co-pilots Lucas di Grassi and Loic Duval. Top honors for the season in LMP2 went to Sergey Zlobin for SMP Racing in the Oreca-Nissan, while Ferrari took the GT title. UPDATE: Mark Webber released the following statement on his condition: "I'm quite sore this morning, am pretty bruised and have got a stinking headache. I've got no recollection of the accident or how it happened. The team is looking into the details to find out more.
