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.

2015 Nissan Murano: Introduction [w/video]

Right as winter turned to spring, a 2015 Nissan Murano was added to the Autoblog long-term test fleet. And while we'd like to report that it's been nothing but smooth sailing, the truth is, as we wrote this, the Murano was undergoing its second stint in the service bay at Suburban Nissan in Troy, MI. It only had 2,400 miles on the odometer. In fact, that's part of the reason why it's taken us so long to introduce this new member of the long-term fleet. After driving the new, third-generation Murano late last year, where we learned that Nissan thinks of its stylish crossover as the flagship for the brand, we decided to order one for a full year's worth of testing at Autoblog HQ. Right from the start, our Murano had problems. At 227 miles, the Check Engine Light illuminated. With no warning messages displayed in the car's onboard infotainment system, we took the Murano to the dealer, where a diagnostic check revealed a faulty O2 sensor. A new part was ordered and we were sent on our way. The Murano went back to the dealer, and now, that issue has been resolved. About 100 miles after the O2 sensor failed, the small storage cover on the center console broke. We aren't really sure how, since this small cubby hasn't had a whole lot of use. Rather than explain it in words, see what's going on in the video below. That's not the only issue we've had with the interior, either. We sort of expected the light, almost white leather to show signs of age during the year-long test, but even after just 2,400 miles, the seats are starting to look worn, with obvious discoloration showing on the driver's seat. What's interesting is, we never had this problem with the light-colored leather on our long-term 2013 Pathfinder. Beyond that, parts of the Murano's interior generally feel poorly put together. The door panels pull away upon light tugging (while closing the door, for example), some of the plastics creak, and we've noticed a few small rattles. Some of this is pretty alarming, especially considering the low mileage of our test car. But it stands to reason that these problems could've been baked in from the start. We're told our car had a couple of issues prior to delivery, and we've heard rumblings from other journalists that their test Muranos haven't been up to snuff. Our early impressions of the Murano were generally positive.
