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.

For next Nissan CEO, priority is profit before Renault partnership

The next head of Nissan Motor Co will need to prioritize a recovery in profits at the troubled Japanese firm ahead of trying to fix its relationship with top shareholder Renault SA, executives and analysts say. Reviving earnings would strengthen the carmaker’s hand in negotiations with its French partner, and is something Renault itself would welcome as the owner of a 43.4% stake in Nissan. JapanÂ’s second-largest automaker said on Monday CEO Hiroto Saikawa would step down on Sept. 16 after he admitted to being overpaid in breach of company rules. ItÂ’s another heavy blow for Nissan, which is already reeling from the arrest of former chairman Carlos Ghosn last year and a subsequent plunge in earnings. Its stock is down 20% this year. For SaikawaÂ’s yet-to-be-named replacement, the top priority will be lifting profits from a more than decade low. Earnings have been undercut by years of heavy discounts and low-margin sales to rental firms that have cheapened NissanÂ’s brand image. Renault, which has unsuccessfully sought a full-blown merger with its larger partner, is likely to give the Japanese firm time to focus on its turnaround, a Nissan executive said. “It goes without saying recovery is the biggest priority,” the executive said, declining to be identified because the information is not public. “We have RenaultÂ’s understanding on that.” Tensions in the Nissan-Renault partnership worsened after GhosnÂ’s arrest. He is awaiting trial in Tokyo on financial misconduct charges that he denies. The strain has sparked investor concern about the future of the Franco-Japanese automaking alliance at a time when car companies desperately need scale to keep up with sweeping technological changes like electric vehicles and ride-hailing. Nissan executives have long complained about their unequal partnership with Renault, which saved the Japanese firm from bankruptcy in 1999. Nissan holds a 15% stake in Renault, but without voting rights. Tokyo is also seen as being uneasy about the French governmentÂ’s 15% holding in Renault, which makes Paris an indirect shareholder in Nissan. “Profitability is likely to remain under pressure and it (Nissan) is unlikely to promptly reach an agreement with Renault over the future shape of the alliance,” analysts at Standard & PoorÂ’s said in a note. Tensions worsened when Renault tried to in vain to merge with Nissan and then Fiat Chrysler.

Nissan names Makoto Uchida as next CEO

TOKYO — Nissan named Makoto Uchida, the head of its Chinese business, as its next CEO, picking an executive known for close ties to top shareholder Renault and for a frank, straight-talking manner that has marked him as an outsider. By selecting Senior Vice President Uchida, Nissan's board has gone with someone slightly at odds with its traditional corporate culture. He joined the carmaker mid-career in 2003, a rarity in a country where top executives usually spend their entire working lives at the same company. Known for his unflagging work ethic and relentless focus on cost control, Uchida was described by one long-time associate who spoke on condition of anonymity as a "foreigner with a Japanese face" — direct and to the point in conversations. He will be joined by newly appointed Chief Operating Officer (COO) Ashwani Gupta, currently COO of junior partner Mitsubishi Motors, in trying to find new ways to revive a business that has been struggling for months with plunging profits, management scandal and tensions with Renault. Japan's second-largest automaker has been shaken in particular by the arrest of former Chairman Carlos Ghosn last year on allegations of financial misconduct, which he denies, and the more recent departure of CEO Hiroto Saikawa after he admitted to being improperly overpaid. Whether the 58-year-old former theology student can deliver a miracle turnaround — particularly at Nissan's business in the United States — and repair ties with Renault will now be a focus for investors. "The biggest business challenge for Nissan is speeding up," the head of Nissan's nominations committee, Masakazu Toyoda, told a news conference. "Speedy decision making is a challenge that Uchida raised, and to this end he said that he wants to empower people as much as possible, so we decided to ask Uchida to take on the CEO role." One source close to Renault described the selection as "a victory for the alliance", saying that both Uchida and Gupta knew the business and were ready to help Nissan recover. 'ISN'T REALLY JAPANESE' Before his ouster, Ghosn had been working on a plan for a full merger of Renault and Nissan, but had met resistance in Japan, which is concerned about French influence in the alliance. The French government is a major Renault shareholder. Relations were further strained this year when Renault held abortive merger talks with Fiat Chrysler Automobiles.
