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 releases new Panamera Edition models

We can't remember the last time we came across a special edition called "Edition," but that's what Porsche is offering with the Panamera. Available on the base, 310-horsepower models, the Panamera Edition is so subtle you'd need to be in the secret owners club to identify it. High-gloss black trim strips outline the windows, it sits on 19-inch Panamera Turbo wheels with colored center caps, the sills are inscribed with the word "Edition," and body-colored door handles are fitted if you pay extra for Porsche Entry & Drive. The cabin gets Porsche logos in the seat headrests, those front thrones being 14-way in the US, climate controlled seats throughout, and a two-tone treatment in black and Luxor Beige. Oh, and special floor mats. Performance upgrades come in the inclusion of active suspension, and convenience comes with the included Park Assist. Tempted? Head to your Porsche dealer in June to take one home. The Panamera Edition will require $80,000, an eminently reasonable (for Porsche) $1,900 premium over the standard car. The Panamera 4 Edition needs $84,300, an even more reasonable $1,500 premium. Destination adds another $995 to both of those prices. The press release below has a few more details.

A new special version of the Porsche Panamera sports sedan stands out through elegant styling combined with a significantly expanded range of standard equipment. Two models with powerful six-cylinder engines will be offered: the Panamera Edition and Panamera 4 Edition both come with an engine that delivers 310 hp. The Panamera 4 Edition features active all-wheel drive with an electronically controlled, map-controlled multi-plate clutch (Porsche Traction Management, PTM). The exterior of the Panamera Edition models is marked by additional subtle design tones, including high-gloss black trim strips on the side windows. The standard 19-inch alloy wheels in Panamera Turbo II design feature wheel center caps with a colored Porsche crest. The door handles are finished in exterior color when Porsche Entry & Drive is optionally selected. The Panamera Edition also boasts a two-tone standard interior in Black / Luxor Beige with the Porsche crest embossed on all head rests, Sport Design steering wheel, door sill plates with "Edition" lettering, and special floor mats.
