Carlos Ghosn takes a walk in a park, as lawyer apologizes for disguise

TOKYO — Former Nissan chairman Carlos Ghosn was seen walking in a Tokyo park on Friday, two days after his release in a strange disguise from a Japanese detention center. Ghosn, this time in sunglasses and a Stanford baseball cap (his daughter Caroline's alma mater), was spotted outdoors twice on Friday, strolling outside in the crisp March air. He and several others, believed to be his wife and daughters, visited a downtown Tokyo garden as members of the media trailed them and watched. The intense media attention was what led Ghosn's lawyers to suggest he leave the Tokyo Detention Center after his release on bail Wednesday in a laborer's outfit of cap, surgical mask and high-visibility vest, attorney Takashi Takano said. Many were baffled by the somewhat transparent disguise, which has riveted Japanese tabloid media. One TV show re-enacted his departure. Takano said in a blog post that he took full responsibility for what he called the "theater of disguise." He apologized for its failure. The outfit was confusing but didn't deter media from tracking the small van he traveled in after his release, in a spectacle broadcast live on television. "My immature plan, as a result, has tarnished the reputation that he has devoted his whole life to build," Takano said of his client. Takano asked the media to respect Ghosn's privacy. That plea appeared to go unheeded as cameramen closely followed the celebrity executive as those walking with him stared straight ahead in apparent annoyance. Ghosn, who headed the Renault-Nissan-Mitsubishi Motors alliance, has been charged with falsifying financial reports, under-reporting his income and breach of trust in having Nissan Motor Co. shoulder personal investment losses and make payments to a Saudi businessman. He says he is innocent and that the income allegedly under-reported was never paid or decided, that Nissan never suffered the investment losses and the payments were for legitimate services. In Japan, suspects are routinely kept in detention until preparations for their trials are ready, meaning they are often detained for months. The court rejected two earlier requests by Ghosn for bail. Ghosn led Nissan for two decades, saving the Yokohama-based automaker from near bankruptcy. He was arrested on Nov. 19.

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's Ghosn called out by Deltawing's Panoz in print ad

When the Nissan ZEOD RC limped to the side of the Circuit de la Sarthe a mere five laps into this year's 24 Hours of Le Mans, we imagine that a certain American motorsports figure at least smirked a little. Don Panoz's ongoing feud with Nissan probably means he wasn't sorry to see the arrow-shaped racecar's poor showing, and now he's stepping up his campaign against his former racing partner.
For those who need a refresher, back in 2012, Panoz and Nissan teamed up to field the DeltaWing, an innovative, wedge-shaped racer, as the first entry in the 24 Hours of Le Mans' experimental Garage 56 concept. The car rapidly became a fan favorite. The Panoz/Nissan alliance didn't last, though, and before long, the DeltaWing's designer was getting a paycheck from Nissan and the ZEOD RC racer arrived. Shortly after that, Panoz began mulling over a lawsuit alleging intellectual property infringement. The American motorsports icon would eventually pull the trigger on a suit back in December of 2013.
Panoz's latest move in the ongoing feud involves an open letter in both The Nashville Tennessean, the paper that serves Nissan's US headquarters, and trade paper Automotive News. The letter calls out Renault-Nissan CEO Carlos Ghosn directly, and points out some of the similarities between the DeltaWing and the ZEOD RC, going so far as to quote the original car's designer, Ben Bowlby.
