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.

Sebastien Vettel testing Infiniti's production Etherea?

It sounds like Sebastian Vettel has had his hands full recently, juggling his Formula One racing career while moonlighting as the newly appointed director of performance at Infiniti. On that latter note, Autocar is reporting that Vettel has been testing a production version of the Etherea Concept at France's Circuit Paul Ricard.
There is still no word as to when we could see this car go into production or what it will be called (possibly the Q30), but it will likely share a platform with the Mercedes-Benz A-Class as a part of the Daimler/Renault-Nissan collaboration. The article also said that this future entry-level Infiniti would be produced at Nissan's Sunderland, UK plant.

Carlos Ghosn video: 'This is about conspiracy. This is about backstabbing'

TOKYO — Nissan's former Chairman Carlos Ghosn maintained his innocence in a video released by his legal team Tuesday and accused some executives at the Japanese automaker of a "conspiracy" that led to his arrest on financial misconduct allegations. "The first message is that I'm innocent," said Ghosn, wearing a white shirt and dark jacket and speaking calmly in the nearly 10-minute video shown at the Foreign Correspondents' Club in Tokyo. "This is a conspiracy," he said. "This is not about specific events, this is not about, again, greed, this is not about dictatorship. This is about a plot. This is about conspiracy. This is about backstabbing." His lawyer Junichiro Hironaka said the video was prepared in case Ghosn was not able to speak at a news conference planned for Thursday. Ghosn was arrested last week while out on bail and remains at the Tokyo Detention Center. Ghosn said the executives behind the conspiracy were motivated by what he called "selfish fears," including what they saw as a merger with French alliance partner Renault SA. They mistook his leadership for greed and dictatorship, when he was the biggest defender of Nissan's autonomy, Ghosn said. He also said he was worried about Nissan, wondering whether those executives were really watching out for the company. Hironaka said a section of the video in which Ghosn mentioned names was removed on his legal advice. Nissan Motor Co., while declining to comment on the criminal case, has said an internal investigation has found that Ghosn falsified financial documents to under-report compensation, and that he used Nissan money for personal gain. "Nissan's internal investigation has uncovered substantial evidence of blatantly unethical conduct," company spokesman Nicholas Maxfield said when asked for comment on Ghosn's video. "The company's focus remains on addressing weaknesses in governance that enabled this misconduct." Ghosn's fourth arrest was on a fresh breach of trust allegation based on suspicion that payments from a Nissan subsidiary to an Oman dealership were diverted to a company effectively run by Ghosn. On Monday, Nissan Motor Co. shareholders voted to oust Ghosn from its board and to approve the appointment of French alliance partner Renault SA's Chairman Jean-Dominique Senard as Ghosn's replacement. Renault owns 43 percent of Nissan.
