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.

2014 BMW M235i

We know a number of BMW owners who reside in the Munich brand's core demographic - upper-five- and six-figure professionals who like to keep their automotive brand credentials as highly respected among their peers as their alma maters or the letters after their names. Before heading to Las Vegas to drive the new M235i, we asked four of those owners, "What did you think of the E30 3 Series?" Although phrased differently, every one of them had the same answer: "What's that?"
You can counter that we just happened to query a tiny and ignorant sample size, and it's possible that you're right. Nevertheless, in every case,we were speaking to BMW's core demographic, the increasing legion of buyers who have fostered another year of record growth and are responsible for BMW retaining its global luxury title for nine straight years. Question that, and we'll refer you to BMW's marketing department, its several hundred PowerPoint slides and several thousand pages of research that prove the point.
That second-generation E30 3 Series built a name, a brand and an entire segment by defining BMW-ness as superlative driving dynamics meets luxury - shortened to the phrase, "The Ultimate Driving Machine." Thirty years later, just being a part of BMW-ness and luxury is enough for the majority of buyers. The superlative handling, that's optional, and 150 hairy guys meet every Tuesday to keep the old religion going, light torches, sing dirges to the siren long gone and bang on their keyboards about the apostasies of modern buyers.
