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 promising autonomous car production by 2020

Nissan will bring the autonomous car to consumers by the end of this decade. The announcement was made by CEO Carlos Ghosn at the company's US headquarters in Irvine, CA. Nissan has already begun construction of a dedicated proving ground for the self-driving cars in Japan, with completion targeted for the end of 2014.
Teaming with MIT, Stanford, Oxford and others, Nissan has already outfitted Leaf EVs with the Autonomous Drive (Nissan's brand name for the tech), a suite of new technologies developed from the brand's existing Safety Shield technology. The current iteration of Autonomous Drive uses the Around-View Monitoring system and laser scanners to analyze the environment, while artificial intelligence systems have been installed to help navigate and operate in a changing environment.
While it's easy to say that Nissan will bring the technology to market within the next six or seven years, it's more difficult to say at what price Autonomous Drive will be available. Most remarkable about all of this is Nissan's claim that self-driving cars will be both commercially viable and available at "realistic prices for consumers." It's expecting Autonomous Drive to be available across its range within two vehicle generations.

Nissan confirms what's in the box

While there were few doubts about what could've been hiding under the giant cardboard box being transported on a flatbed truck earlier this month, Nissan has officially confirmed that it was, in fact, a Versa Note being delivered from Amazon.
As a part of the special promotion, online shoppers who bought a Versa Note using the retailing giant also received a $1,000 Amazon gift card. Scroll down to watch how the car was packaged and shipped as well as what the buyer did with all that cardboard.
