Nissan, Renault break up the Ghosn-style almighty chairmanship

YOKOHAMA, Japan — Japan's Nissan Motor and France's Renault said they would retool the world's top car-making alliance to put themselves on more equal footing, breaking up the all-powerful chairmanship previously wielded by ousted boss Carlos Ghosn. The removal of Ghosn, credited for rescuing Nissan from near-bankruptcy in 1999, had caused much uncertainty about the future of the alliance and some speculation the partnership could even unravel. The companies, together with junior ally Mitsubishi Motors, on Tuesday said the chairman of Renault would serve as the head of the alliance but — in a critical sign of the rebalancing — not as chairman of Nissan. "This is a very special day for the alliance," Renault SA's chairman, Jean-Dominique Senard, told reporters after a meeting at Nissan's Yokohama headquarters. He spoke to reporters along with Renault's chief executive, Thierry Bollore; Nissan CEO Hiroto Saikawa; and Osamu Masuko, CEO of the smaller Japanese alliance partner Mitsubishi Motors Corp. Those four executives will meet every month in Paris or Tokyo and oversee various projects, helping to make the companies' operations more efficient, they said. Nissan has said that Ghosn wielded too much power, creating a lack of oversight and corporate governance. It was not clear who would become Nissan's chairman, vacant since Ghosn was arrested in Japan in November. But the automakers gave no indication of any immediate change in their cross-shareholding agreement, one which has given smaller Renault SA more sway over Nissan. The alliance did not announce any changes in mutual stake holdings. The so-called Restated Alliance Master Agreement that has bound them together so far remains intact, they said. "We are fostering a new start of the alliance. There is nothing to do with the shareholdings and the cross-shareholdings that are still there and still in place," Renault Chairman Senard said. "Our future lies in the efficiency of this alliance," he told reporters at Nissan's headquarters in Yokohama. Senard also said he would not seek to be chairman of Nissan, but instead was a "natural candidate" to be vice-chairman. Former Nissan chairman Ghosn was released on a $9 million bail last week after spending more than 100 days in a Tokyo detention center.

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.

Nissan, Infiniti issue recall for replacement Takata air bags in older models

Nissan and Infiniti are recalling older vehicles that were repaired after collision damage to address problems with Takata replacement air bag inflators that were potentially installed. The overall campaign population is difficult for Nissan to pin down because the only vehicles impacted would be those that Nissan and Infiniti know to have been serviced with the replacement units in question. Officially, the recalled population numbers just 375, but Nissan says more than 18,000 cars could have the defective parts installed.  Drivers of 2001-2003 Nissan Maximas, 2002-2006 Nissan Sentras, 2007-2012 Nissan Versa Sedans/Hatchbacks, 2002-2003 Infiniti QX4s and 2006-2010 Infiniti M35s/M45s that had their vehicles repaired after a collision or theft should be aware that these deadly replacement parts may have been used.  "The potentially affected inflators may have been installed on vehicles after final remedy repair completion under the vehicle recalls as part of a subsequent theft or collision repair," Nissan's notice said. "Vehicles that received the subject parts prior to December 9, 2016, are not affected as they would have been subsequently included in the final remedy recalls and replaced with a final remedy driver and/or passenger air bag inflator. Nissan has identified 18,422 vehicles that may have had these parts installed during service." The air bag inflators in question were inadvertently shipped to service inventory between December 9, 2016 and November 12, 2021 — after the dangers of Takata's inflator design were known to the industry. Notices are already being mailed; owners will be asked to bring their cars in for inspection, and if defective parts are found, they will be replaced.  Related video: This content is hosted by a third party.
