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.

Carlos Ghosn 'very comfortable' after questioning by Lebanese prosecutor

BEIRUT/TOKYO — Carlos Ghosn's lawyer said he was "very comfortable" with legal proceedings in Lebanon on Thursday, after the fugitive ex-Nissan boss was questioned over an extradition request from Japan where he faces criminal charges. Ghosn fled Japan to Lebanon, his childhood home, last month as he awaited trial on charges of under-reporting earnings, breach of trust and misappropriation of company funds, all of which he denies. His dramatic escape has raised tension between Tokyo and Beirut at a time when Lebanon is seeking an international bailout to help it tackle a deep financial crisis. Ghosn slammed the Japanese justice system at a two-hour news conference on Wednesday, prompting Japan's justice minister to launch a rare and forceful public response. After questioning in Beirut about Japan's Interpol wanted notice, two judicial sources said the prosecutor had imposed a travel ban, a step Carlos Abou Jaoude, a Beirut-based lawyer for Ghosn, described as procedural to broadcaster Al Jadeed. Lebanon has no extradition agreement with Japan. "He (Ghosn) is very comfortable with the path," Jaoude told another broadcaster, MTV, adding that Ghosn was also comfortable in himself "especially after what he went through."   Related: CES 2020 and Carlos Ghosn | Autoblog Podcast #609 Ghosn: Nissan-Renault strife and his arrest can be traced back to Macron The rise, fall and flight of Carlos Ghosn   One of the judicial sources said authorities had asked Japan for its file on Ghosn, including the charges against him, and would not question him again until the information is received. Ghosn would surrender his French passport on Thursday, he said. Ghosn said later he was more comfortable with the Lebanese judiciary than that of Japan. "I will fully cooperate," he told broadcaster LBCI. Japan's Justice Minister Masako Mori said Ghosn's allegations that he had had "zero chance" of a fair trial in Japan were unfounded. "Defendant Ghosn was looking to justify his unlawful exit from Japan by propagating a false recognition of our justice system," she said at the second of two news conferences, the first of which was held shortly after midnight. "I felt that we needed to respond immediately to broadcast a correct understanding to people around the world." Ghosn told LBCI her comments were "ridiculous." "Today my concern is clearing my name and reputation because all the accusations against me are fabricated," he told Al Jadeed. Trial in Lebanon?

Nissan Micra gets fresh new look [w/video]

Nissan has given its popular Micra a substantial refresh. Completely revised fascias front and rear join small sheetmetal tweaks for an all-new look, and Nissan says buyers can expect to find a host of new technology indoors. That includes audio USB and AUX-in slots as well as a new audio and touchscreen navigation system with a larger display. Designers have also graced the model - known in some markets as the Nissan March - with a revised center console and new trim indoors. Be still our beating hearts.
Under the hood, a supercharged, direct-injection 1.2-liter gasoline three-cylinder engine continues to produce 97 horsepower, complete with a stop/start system that Nissan says helps make this powertrain one of the most efficient in the world. Buyers can also opt for diesel and non-supercharged engines if they so choose.
While periodically rumored, Nissan has no plans to bring the model to North America, but with sales in 56 nations and assembly in four different countries, the little Micra remains a big deal worldwide. You can check out an official video and press release below for more information.
