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 engine wizard Wolfgang Hatz resigns

Wolfganag Hatz has resigned from his position as Member of the Porsche Executive Board with responsibility for Research and Development. He has held that title since 2011. Hatz's storied career came to an abrupt end in September when he was suspended pending investigation into the Volkswagen diesel scandal. Before the Porsche job, Hatz was the head of engine and powertrain development for the Volkswagen Group. It has been alleged that he is at the center of the investigation into the company cheating on emissions testing, but so far there has been no direct link made to him, according to Porsche's announcement today. Hatz has worked at a variety of European automakers, including Audi, BMW, Opel, and Fiat. He is considered the father of the BMW S14 engine, which powered the E30 M3, and also developed the Porsche 911 Carrera RS 3.8. He was also very involved in Porsche's motorsports efforts, including the recent return to the prototype class and a short-lived F1 V12 engine project. Ulrich Hackenberg, most recently VW's lead engineer and a board member at Audi, was also suspended at the same time as Hatz and resigned shortly thereafter. It's not clear why Hatz waited so long to do the same, but Porsche claims his resignation was voluntary. Michael Steiner has been named Hatz's replacement as head of Porsche R&D. Steiner has been with Porsche since 2002 and seems like a forward-thinking sort, having headed the innovation and concepts division, lead Panamera development, and, most recently, been in charge of complete vehicle engineering. Prior to his time at Porsche, Steiner held positions at Daimler. The change in leadership is effective immediately. Related Video:
