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.

Kaz and Shiro talk Gran Turismo 7 details, Titan Nismo and more in AMA

One of the greatest innovations to come about thanks to the gigantic popularity of Reddit is the Ask Me Anything (AMA) question and answer format. The AMA becomes especially worthwhile, of course, when the person(s) answering the questions have detailed information or insight on products we love.
So, in the case of the recent AMA session with Gran Turismo creator and mastermind Kazunori Yamauchi (above), and his buddy and Nissan chief designer Shiro Nakamura (right), it was basically must-read stuff.
The pair really lived up to our expectations, too, with Kaz offering a lot of useful information about the future of the Gran Turismo franchise (especially the upcoming GT7 for Playstation 4), and Shiro promising to bring some interesting new ideas back to his colleagues at Nissan.

Carlos Ghosn launches initiative to help his native Lebanon

BEIRUT — Former Nissan Motor Co. Chairman Carlos Ghosn made a new public appearance in Lebanon Tuesday during which he launched an initiative with a local university to help the country that is undergoing a severe economic and financial crisis. It is GhosnÂ’s second appearance in public since he was smuggled from Japan in late December to his ancestral Lebanon. In early January, Ghosn gave a news conference in Beirut saying he fled because he could not expect a fair trial, was subjected to unfair conditions in detention and was barred from meeting his wife under his bail conditions. Ghosn declined to elaborate about the details of his arrival in Lebanon, saying it happened in “dramatic circumstances” and also refused to answer questions regarding two Americans who allegedly helped him flee Japan to Lebanon through Turkey. He also refused to talk about former Nissan executive Greg Kelly, who is standing trial in Japan. Ghosn said that the initiative with the Maronite Christian Holy Spirit University of Kaslik, USEK, titled "Moving Forward," aims to launch a top executive management program, a training center on new technologies and to support startups. “The objective is obviously serving this institution ... but also serving the country and the society,” Ghosn said in an opening speech. “If there is one specific thing that Lebanon needs it is create jobs.” “When we are developing top management, we are developing people strong enough to carry companies through this difficult time, to grow a company and to create jobs,” Ghosn said. Lebanon is mired in the countryÂ’s worst economic and financial crisis in its modern history. It defaulted on paying back its debt for the first time ever in March, and the local currency has collapsed, leading to hyperinflation and soaring poverty and unemployment. Talks with the International Monetary Fund on a bailout package have stalled. The economic and political crisis deepened after an Aug. 4, blast in Beirut that killed and wounded many and caused damage worth billions of dollars. Many Lebanese consider Ghosn as one of the countryÂ’s heroes in the diaspora who succeeded in turning troubled car companies in France and Japan into profit making ventures. Some have suggested that Ghosn should be given a governmental post in Lebanon to get the country that is notorious for corruption and mismanagement out of its troubles.
