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.

Basic Continuously Variable Transmission explained with Legos

In recent years, the search for better fuel efficiency and smoother shifting has produced automatic transmissions with double-digit gears. Alternatively, the same quest has boosted the popularity and usage of a different type of automatic transmission without any fixed gears, the continuously variable transmission, or CVT. YouTuber Sariel's Lego Workshop recently took the time to build a CVT demonstration model out of Legos to help explain how they work. Sariel begins by showing the model's input and output shafts that are parallel to each other. Each shaft has a cone attached to it, and they are inversely placed so that the large part of one cone is next to the small part of the other cone. The two cones are connected using a rounded rubber band.  By shifting the rubber band up and down the cones, the machine changes the effective ratio between the cones. So, a 1:4 ratio can be smoothly transitioned to 4:1. No clutch is required to operate the mechanism, and it eliminates hitches or pauses between gear changes. CVTs are also advantageous over 9- or 10-speed automatics in that they are far less complex and weigh less.  To demonstrate how the CVT operates in a vehicle, Sariel used a joke about Top Gear. The original Top Gear is represented by a faster-moving car that has the rubber band around the large part of the cone on the input shaft. Top Gear without former hosts Richard Hammond, Jeremy Clarkson, and James May is represented by a slow-moving car with the rubber band around the large part of the cone on the output shaft.  For an even more detailed explanation of how CVTs work — albeit one that doesn't involve toys — you can click here.

Waymo partners with Nissan, Renault on robotaxis outside U.S.

SAN FRANCISCO — Self-driving car pioneer Waymo is teaming up with automakers Renault and Nissan to make its first journey outside the U.S. with a ride-hailing service that will dispatch a fleet of robotaxis in France and Japan. The partnership announced late Wednesday underscores Waymo's ambition to deploy its driverless technology throughout the world in an attempt to revolutionize the way people get around. The Mountain View, California, company can afford to try because it's backed by one of the world's richest companies, Google, which secretly began working on driverless technology a decade ago before spinning off that project into what is now known as Waymo. After launching its ride-hailing service in France and Japan, Waymo intends to explore other European and Asian markets with Renault and Nissan. "This is an ideal opportunity for Waymo to bring our autonomous technology to a global stage," Waymo CEO John Krafcik said. Waymo, Renault and Nissan didn't set a timetable for when their ride-hailing service will launch. They left most other details vague. It seems likely it will still be several years before Waymo will be in a position to pose a serious challenge to Uber, the world's largest ride-hailing service. Although Waymo's self-driving technology is widely considered to be the world's most advanced, it still isn't adept enough to be trusted without a human poised to take control in case something goes awry with the robot. Waymo had hoped to launch a fully autonomous ride-hailing service last year in the Phoenix area, but instead is still keeping human safety drivers in those vehicles more than six months after it rolled out. That service, known as Waymo One, is still only offering rides to a few hundred passengers that previously participated in a test program. Krafcik told the German newspaper Handelsblatt last year that Waymo will likely use a different brand for its ride-hailing services outside the U.S. That could be one reason Waymo is working with France-based Renault and Japan-based Nissan, household names in their home countries. Waymo has previously struck deals with two automakers, Fiat Chrysler and Jaguar, but those involved ordering tens of thousands of vehicles to be equipped with self-driving technology for services in the U.S. So far, Waymo is only using Fiat Chrysler minivans for its Phoenix service. The partnership with Renault and Nissan also involves a long-time alliance they formed with Mitsubishi.
