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 stalls on Ferrari 458 rival

A few years ago, reports surfaced that Porsche was planning a new supercar. But the latest intel suggests that the plan has been put indefinitely on the back burner.
The project alternately referred to as 960 or 988 was put forth by CEO Matthias Müller shortly after he assumed control of the German automaker. It called for a mid-engined V8 supercar to slot in between the 911 and the 918 Spyder to take on the likes of the Ferrari 458 Italia, McLaren 650S and sister-company Lamborghini's Gallardo and subsequent Huracán.
Now three years since the idea was first mooted, the vehicle has yet to materialize. According to Autocar, Porsche is putting a greater emphasis on refreshing its existing lineup. Which is probably just as well, because the mid-engined supercar would have a heck of a challenge on its hands to differentiate itself in terms of performance from the 911 GT3 and 911 Turbo, which already give the 458 and company a run for their money.
