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 executive Jun Seki resigns to become president of Nidec

YOKOHAMA, Japan — The executive tasked with leading a recovery at Nissan said he had decided to resign just weeks into his new job, a move that could disrupt the automaker's push to turn the corner on scandal and slumping sales. Jun Seki, Nissan's vice chief operating officer and a former contender for chief executive, told Reuters he was leaving to become the president of Nidec, a Kyoto-based manufacturer of automotive components and precision motors. He will likely depart in January after three decades at Nissan, including a stint heading its China business. "I love Nissan and I feel bad about leaving the turnaround work unfinished, but I am 58 years old, and this is an offer I could not refuse. It's probably my last chance to lead a company too," he said in a brief interview. "It's not about money. In fact, I will take a financial hit since Nissan pays us well," Seki said. He declined to elaborate further. Nissan and Nidec declined to comment. Seeking to roll back some of the costly expansion under ousted chairman Carlos Ghosn, Nissan has embarked on wide-ranging turnaround plan. That plan, which began in April, is now on track to generate a cumulative few hundred billion yen in cost cuts and operational efficiency gains by the year to March 2022, according to two Nissan sources who spoke on condition of anonymity. One hundred billion yen is roughly equal to $915 million (707 million pounds). Adding to concerns about disruption among Nissan's top management, the sources said that Seki, Chief Operating Officer Ashwani Gupta and Chief Executive Makoto Uchida have so far failed to gel as a team after being named to their posts in October. They officially took over on Dec. 1. "There was no instant, cohesive chemistry achieved by those appointments," one of the sources said. Gupta and Uchida were not immediately available for comment. Seki's resignation could further complicate Nissan's relationship with top shareholder Renault SA. Seki recently worked in Paris for a year and was seen as relatively close to the French automaker. PERSUADED IN THE END Asked if he was leaving Nissan because he was passed over for the role of chief executive, Seki said that was not the case but did not elaborate. He and Uchida, most recently the head of the China business, had been seen as top contenders for the CEO job. Reuters reported in September that Uchida was seen as more favored by Renault.

Mercedes, Nissan and VW slammed by China's CCTV

Several automakers in China, including joint ventures with Nissan, Volkswagen and Mercedes-Benz, are in hot water because their dealers are allegedly overcharging customers for repairs. China Central Television, the country's state broadcaster, leveled the claims during its annual Consumer Day expose. CCTV runs these reports each year on March 15 and often takes aim at foreign companies operating within China. This year the focus fell on automakers, according to the Financial Times, and no domestic car companies were targeted. The network also accused dealers of overselling parts, and it took aim at Jaguar Land Rover specifically for problems surrounding transmission repairs, according to Reuters. The yearly stories are often criticized for focusing on outside businesses. "It panders to a certain type of nationalism as it tends to target foreign companies and rarely touches large state groups or monopolies," Qiao Mu, a journalism professor at Beijing Foreign Studies University, said to the Financial Times. Foreign automakers seem to face tighter scrutiny when doing business in China than their domestic counterparts, in general. The government there investigated several luxury brands, including Audi and BMW, last year for how they supplied spare parts and whether the components were overpriced. Some incurred fines, and Lexus decided to lower its prices. Volkswagen also experienced protests when owners felt the company wasn't handling a recall properly. The CCTV report also comes as many auto dealers in China are feeling a pinch due to high mandated sales targets from automakers. The situation was so dire in early 2015 several brands cut back sales targets and in some cases even paid the sellers to offset poor profits.
