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.

Renault will split EV from combustion unit, seeks partnerships

PARIS — Renault has received several partnership proposals for the combustion engine unit it plans to create alongside one dedicated to electric vehicles and software, two sources familiar with the matter said. Renault plans to separate its electric and conventional car businesses, creating two entities to manage the shift towards fossil-free vehicles. "The group has already received partnership demands" for its internal combustion engine unit, one of the sources said. By bringing in partners on the combustion engine side Renault aims to free up funds to invest in electric vehicles, a technology in which it was a pioneer with Nissan and Mitsubishi, but in which it is now eclipsed by pure players such as Tesla. Renault intends to retain majority ownership of its electric division, which will employ about 10,000 people and which could be bourse-listed via an IPO in the second half of 2023. However, it will only remain a reference shareholder, not a controlling shareholder, of the combustion engine unit, which will have similar staff levels, said two other sources familiar with the plans. One of the sources said Renault may hang on to a 40% stake. Renault declined to comment. The carmaker at a capital market day this autumn will set out its plans for its electric arm based in France and the combustion unit headquartered abroad. That entity will include factories producing engines and gear boxes for gasoline and hybrid cars in Spain, Portugal, Turkey, Romania and Latin America. Among potential partners for its combustion engine business, CEO Luca de Meo in April mentioned Nissan, other automotive groups and long-term investors. De Meo is set to travel to Japan next month to discuss potential Japanese participation in its electric and combustion engine projects. Renault is undergoing a major restructuring aimed at restoring its finances and recently signed partnerships beyond its historical alliances with Nissan, Mitsubishi and Mercedes, such as with China's Geely Automobile Holdings. This month it sold 34% of its South Korean unit to Geely, which owns Volvo Cars and is a shareholder in Mercedes. With Geely, Renault plans to develop hybrid vehicles which will be assembled in its plant in Busan, South Korea. Earnings/Financials Green Mitsubishi Nissan Renault
