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.

Next-generation Panamera will spawn variants, Sport Turismo in the running

A few years ago it took actual willpower not to consider what kinds of cool derivatives Porsche could make with the Panamera. Our fancies were helped by patent drawings of a Panamera convertible, rumors of a two-door 928 GT and internal Porsche sketches of such a car, and report after report after report that the current, second-generation Panamera would begin to expand the family. That hasn't happened, but according to a new report in Auto Express, the next Panamera will be the one to begin the bifurcation. Wolfgang Hatz, the brand's head of research and development, told the mag that, "We have prepared it for a lot of derivatives, personally I like very much the Sport Turismo." The Panamera Sport Turismo, remember, was the hybrid, concept wagon that rolled into the 2012 Paris Motor Show and made everyone ask, "Why didn't you build this design from the beginning?" It could have been Hatz's English, but after professing his ardor for the Sport Turismo, the executive said, "But there is a good chance for more derivatives." We're not sure if that means the Sport Turismo is all but approved, or if he was speaking of the third generation Panamera's new MSB platform in general. Even though Hatz mentioned a coupe and convertible, it sounds like that latter variant won't be happening, Hatz saying that the brand already has the Boxster and 911 Cabriolet. We're willing to forgive that omission – who's really looking for a four-door convertible, anyway? – and welcome the Sport Turismo first if Hatz will please please please get us a new 928.

50th Anniversary Porsche 911 vs. Jaguar F-Type Coupe is a battle of beauty, brawn

There can't really be a loser between the Jaguar F-Type Coupe R and the Porsche 911 50th Anniversary Edition. One might be better than the other, but if you're behind the wheel of either of them, you can't complain. In a new video, Motor Trend takes on the difficult task of determining which one of these European powerhouses is the best, not just in terms of raw performance, but also how they actually feel to drive.
The Porsche 911 is one of the perennial favorites of the motoring world. It just doesn't go away and always seems capable of challenging the top vehicles in its class. In this video, Motor Trend takes a look at the 50th Anniversary Edition model that celebrates that heritage while boosting power somewhat over the standard version.
The F-Type Coupe is an incredibly masculine car, MT describing it as "a British Corvette." The coupe's exterior lines are tautly stretched over its athletic body, and it's supercharged 5.0-liter V8 sounds like a demon's growl. Jaguar seems to have things right with its latest sports car.
