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.

2015 Nissan Versa Sedan continues to prioritize space and price over looks

Nissan's refresh of its cavernous Versa Sedan is on hand today at the 2014 New York Auto Show. While we continue to appreciate the Versa for its space and low price, this slight restyling of the four-door sedan hasn't done much for its uninspiring appearance.
Newly enlarged headlights and a reworked, more Altima-like grille are the biggest changes to the front of this Versa, although Nissan has also added some brightwork around the revised foglight housings. Integrated turn signals liven up the mirrors, while the rear of the car wears a new and almost strangely sporty bumper.
Perhaps more importantly for prospective owners, Nissan has also made a few interior tweaks, with a new steering wheel and a revised center stack leading the change. There's some new available tech on the top-end SL model, as well.

Carlos Ghosn's lawyer requests bail again after Nissan ex-chairman indicted — again

TOKYO — Japanese prosecutors indicted Carlos Ghosn on Monday on another charge of aggravated breach of trust, a Tokyo court said, the fourth charge against the former Nissan Motor Co Ltd chairman, which his lawyers met immediately with a bail request. The charge came on the day Ghosn's latest detention period was set to expire. Ghosn had been out on bail when authorities arrested him for a fourth time on April 4 on suspicion he enriched himself at a cost of $5 million to the automaker. "We are confident that we have the evidence to successfully prosecute all four cases," an official from the prosecutor's office said at a briefing after the indictment was announced. Ghosn has denied all four of the charges, which include understating his income, and said he is the victim of a boardroom coup. He has accused former colleagues of "backstabbing," describing them as selfish rivals bent on derailing a closer alliance between Nissan and its top shareholder, France's Renault SA. "Carlos Ghosn is innocent of the latest charges brought against him by the Tokyo prosecutors, aided and abetted by certain Nissan conspirators," a Ghosn representative said in a statement. The case has exposed tensions in the Nissan-Renault alliance forged by Ghosn some two decades ago when the French automaker invested in Nissan, then on the brink of bankruptcy — a deal that gave Renault control over its larger partner. Nissan is due to reject a management integration proposal from Renault and will instead call for an equal capital relationship, the Nikkei newspaper said on Monday, citing sources. Ghosn's arrest has also focused a harsh light on Japan's judicial system, which critics refer to as "hostage justice" as defendants who deny their charges are often not granted bail. Under Japanese law, prosecutors are able to hold suspects for up to 22 days without charge and interrogate them without their lawyers present. In accordance with these terms, prosecutors had to indict or release Ghosn by Monday. According to the latest indictment, Ghosn caused a total of $5 million in losses to Nissan from July 2017 through July 2018. During that period, prosecutors allege two separate payments of $5 million were made from the account of a Nissan subsidiary into the account of an overseas dealership. A total of $5 million was subsequently transferred from the dealership's account to another account in which Ghosn had an interest.
