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.

Nissan leaning on JATCO to remedy CVT problems

Nissan's decision to fit continuously variable transmissions across even more of its new models may be coming back to bite the Japanese automaker, as it's been hampered by customer satisfaction issues relating to its XTronic CVTs, which are provided by a supplier called JATCO.
From what we're understanding, the issue largely relates to customers' unfamiliarity with the non-traditional shift nature of a CVT. Dealers have reported complaints and service visits from owners over the belt-driven automatics (did these people not test drive the cars before they bought them and notice that they don't shift conventionally?).
The company, which Nissan owns 75 percent of, has come under fire from none other than Nissan CEO Carlos Ghosn, who's spoken about JATCO and its troubles rather openly. "Every time you launch a new CVT you always have some risks," Ghosn said in an interview with Automotive News. "So we now have a process by which, before we launch any new CVT, [JATCO] come before the Nissan executive committee to explain all the measures they have taken to make sure there are no surprises."

'Qashqai' so hard to pronounce even Nissan is poking fun at it

In the US, there aren't a lot of vehicle names that are very difficult to pronounce. Maybe the Volkswagen Touareg might trip up a few people, but by and large, we've got it pretty easy. Our friends in Europe, though, have a bigger challenge, thanks to vehicles like the Nissan Qashqai. Yes, Qashqai.
Like the Touareg, the Qashqai draws its name from a nomadic people. While Nissan isn't making up words, then, it's still not an easy name to pronounce. Top Gear host Jeremy Clarkson routinely calls it a kumquat, for example. According to Nissan, though, it's pronounced "Cash'kai".
To get its point across as the second-gen Qashqai, the close cousin of the US market Rogue, prepares to launch in Australia, Nissan set up a little event at a coffee shop. Customers would place their orders, only to have the spelling of their names butchered rather badly. On the other side of the cup, there's a message from Nissan and the Qashqai.
