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.

The Bearable Lightness Of Being
Start with a standard Porsche 911 Carrera and its 350-horsepower, 3.6-liter flat six-cylinder engine. Bore a crepe-thin slice of aluminum from each cylinder to get to 3.8 liters, add a wider track out back and two extra exhaust pipes and voila, you can append an S to the Carrera's name. Hang two sets of wet, multi-disc clutches along its spine and you can make that a 4, or a 4S. Bolt on two forced-induction compressors and piping, add two fender vents and comically wide rear tires and you've redeemed your ticket to a Turbo. Increase the boost pressure and swell the corral to 560 horses and you have the Turbo S, which is the Virginia Slims of the 911 line-up because it's come a long way, baby.
Or you can go in a different direction. At that second stop, grab the 3.8-liter and cart it over to the engineers at Porsche's development center in Weissach, Germany. If racing were meat, they would be among the alpha carnivores. The baseboards in their homes are probably painted with miniature billboards for motor oil and vintage cigarettes along the straights, red-and-white stripes around every corner.

New details mooted about Porsche's '988' Ferrari rival

We could be on the verge of a big expansion at everyone's favorite rear-engined German sports car manufacturer. Porsche is allegedly preparing a four-car assault that will be led by a proper challenger to the Ferrari 458 Italia (sorry 911).
Code-named "988," the new model will reportedly feature a mid-engined layout and, get this: a flat-8. Autocar, which has the story, expects that engine to displace about 4.0 liters, while the car itself will draw styling inspiration from the 918 Spyder. 600 ponies and over 400 super-accessible pound-feet of torque should be on tap with the new mill.
Joining the 988's supposed eight-cylinder is a new family of four- and six-cylinder boxer engines that Autocar claims will have a focus on power density and fuel economy. These new mills will be available in naturally aspirated, turbocharged and hybrid forms.
