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 Murano production fires up in America for first time [w/video]

Production of the new, third-generation Nissan Murano has finally kicked off at the company's Canton, MS factory, marking not only the eighth vehicle built on the facility's lines, but also the first global product to be built there since it opened in 2003.
"The strategic investments that Nissan has made in Canton serve as a testament to the flexibility, efficiency and talent of our workforce and suppliers," said John Martin, Nissan's boss for manufacturing, supply chain management and purchasing. "In Canton, we build high-quality vehicles that compete and win globally, and the bold new Murano will build on that reputation."
The addition of Murano production, which joins Altima, Armada, Titan, Frontier, Xterra and NV, brought a further 1,300 jobs.

NRG eVgo ready for 'No Charge to Charge' in Atlanta

That loop of highways circumnavigating the city of Atlanta is about to get some fast chargers. And, for those driving newer Nissan Leaf electric vehicles, some free chargers as well, for the next couple of years. It's the new taste of southern hospitality. NRG Energy, which has been expanding its NRG Evgo fast-charging networks across the country, is now going into the Atlanta metro area. The stations, which can fully charge an electric vehicle in as few as 30 minutes, will be located "along major thoroughfares in retail locations." This makes sense, since Atlanta has emerged as a major plug-in vehicle market this year. Additionally, the "No Charge to Charge" program that NRG eVgo helps administer will apply in NRG eVgo's Atlanta network. That means that Georgians who either buy or lease Leaf EVs will be allowed to charge their cars at the eVgo stations for free for the first two years. Other eVgo programs are up and running in Texas, Phoenix, Nashville, Washington, D.C. and the Pacific Northwest. Last month, the NRG eVgo program took over a proposed fast-charging network in Chicago, where charging-station deployments had stalled. Take a look at the NRG eVgo press release for Atlanta below. NRG eVgo Announces Electric Vehicle Charging Network in Atlanta ATLANTA, December 09, 2014 – NRG eVgo, a subsidiary of NRG Energy, Inc. (NYSE:NRG), is expanding its comprehensive electric vehicle (EV) infrastructure designed to support EV drivers whenever and wherever they choose to charge - at single family or apartment residences, at work, on the road, or even at the airport to the Atlanta metro area. The new network will give Atlanta EV drivers unprecedented access to cutting-edge fast charging technology and bring much-needed EV infrastructure to the region. "We are pleased that NRG has chosen to expand its eVgo charging network in the City of Atlanta," said Mayor Kasim Reed. "Establishing a robust fast-charging network is essential to even broader adoption of electric vehicle use, both here in Atlanta and across the country." Recently, according to IHS Automotive, Atlanta emerged as the second major metropolitan market for EV sales, following San Francisco. Atlanta is geographically large, meaning most people commute to work, and have a need for a sustainable, reliable charging infrastructure.
