Ousted Renault CEO Bollore raised concerns over Ghosn investigation

PARIS — Renault's former chief executive Thierry Bollore, who was ousted in October, had sought to flag alleged conflicts of interest and governance problems at the company's Japanese alliance partner Nissan before his departure, Le Monde reported on Monday. Citing a letter from Oct. 7 addressed to Nissan's board, of which he was member, France's Le Monde newspaper said Bollore had raised questions over the firm's internal investigation surrounding former alliance boss Carlos Ghosn. Nissan and Renault were left reeling by Ghosn's arrest in Tokyo a year ago, on financial misconduct charges which he denies. They have since tried to reboot their strained partnership by revamping their management teams, including by purging them of Ghosn allies and removing people in top jobs at the time of the scandal. Bollore — who took a step up at the French carmaker when Ghosn left even though he was known for his close ties to the alliance founder — was eventually pushed out as Renault's CEO on Oct. 11, days after penning his letter. In comments sent to Reuters, Nissan spokeswoman Azusa Momose denied there were any irregularities in its internal investigation of Ghosn's affairs, and added that the company had reviewed its processes once again following Bollore's letter. "Nissan's independent directors confirmed that the investigation was properly conducted and could be relied on," Momose said. Nissan directors had discussed all the allegations raised by Bollore and the company "concluded that Bollore's concerns were not founded and were based for the most part on inaccurate information and speculation," she added. Bollore said in the letter that he was particularly concerned by the revelation that Nissan had a list of 80 managers implicated in financial dealings similar to the ones attributed to Ghosn. He also raised issues with the chain of command at Nissan, saying some key board members were sometimes kept in the dark on internal matters. Renault, which is still searching for a permanent replacement for Bollore as CEO, had no immediate comment. As well as changing its CEO, Nissan recently demoted senior vice president Hari Nada — a key whistleblower against Ghosn and whose role was also questioned in Bollore's letter — although its internal investigation had found no evidence against the executive.

A journey to our driving future | Autoblog in Japan

TOKYO — We here at Autoblog recently went to Japan to drive cars, ride trains and talk to people about the past and future of mobility. In 1964, Japan hosted the Summer Olympics. To showcase to the world how far they had come since WWII, Japan launched its latest marvel in mobility, the Shinkansen (or as we call it, the Bullet Train). In 2020, Japan is hosting the Summer Olympics in Tokyo, and this time the nation is prepared to showcase a huge push toward autonomous cars. Green Editor John Beltz Snyder, Senior Producer Christopher McGraw and Associate Producer Alexander Malburg traveled there to get a sense of the country's transportation ecosystem with the 2020 Games on the horizon, and we filmed the experience along the way. In this series of videos, you'll see us try out car features that aren't yet available in the U.S., talk to an expert at Nissan about electric and autonomous mobility, ride the incredibly fast Shinkansen bullet train between Tokyo and Kyoto, pay homage to Soichiro Honda — and Ayrton Senna — at the Honda Collection Hall at Twin Ring Motegi, and see some beautiful and historic sites along the way. Here's what we'll be showcasing from our trip to Japan. Check back here as we update the list with links to all the videos: Driving a Subaru WRX equipped with EyeSight with Touring Assist Reviewing the 2018 Nissan Leaf on the roads of Japan Testing ProPilot Park on the Nissan Leaf Talking with Nicholas Thomas, Nissan's director of electric vehicles How to ride the Shinkansen in Japan (We love trains!)

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.
