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.

2011-2012 Nissan Leaf class-action lawsuit finally settled

In 2012, a group of Nissan Leaf owners sued the automaker in a class-action lawsuit over the "wilting Leaf" issue. That describes the steadily decreasing battery capacity of the electric vehicle's battery pack, which didn't line up with drivers' expectations. At the time, Nissan said the lawsuit was without merit but the legal wranglings continued. A new, $24-million settlement will give Leaf owners a new (not repaired) battery if their current pack drops down to fewer than nine bars of energy capacity. There are also options for 90 days of free charging at some of the No Charge To Charge locations or, if they don't live near any of those, a $50 check. One of the main complaints of the lawsuit was that the initial ads for the EV were less-than-clear, telling people the car could go 100 miles when fully charged but, and here's the problem, the automaker recommended that Leaf owners not charge their cars up all the way in hot climates. The class action suit was filed on behalf of Leaf owners in California and Arizona. It reads, in part: Before purchase or lease, Nissan failed to disclose its own recommendations that owners avoid charging the battery beyond 80% in order to mitigate battery damage and failed to disclose that Nissan's estimated 100 mile range was based on a full charge battery, which is contrary to Nissan's own recommendation for battery charging. Following early reports of the wilting problem in warm climates and the initial filing of the lawsuit, Nissan upgraded its battery warranty. It also improved the EV's battery chemistry. The class action suit says that it's this new chemistry that needs to go into any "wilting Leafs" that are affected by the suit. There's more information at the class-action site. Nissan told AutoblogGreen it does not typically discuss litigation.

2013 Nissan Juke Nismo

Scratching All The Right Itches
Say what you will about the unconventional aesthetics that Nissan employed on the company's Juke. I love the thing. The universe has no shortage of ambiguously styled CUVs, and while I can't exactly say I would have turned to the amphibian world for design inspiration had it been me with the charcoal in my hand, I can certainly appreciate the fact that the Juke isn't just another box-on-box design.
And then there's that engine. The turbocharged 1.6-liter four-cylinder under the hood is one of the best powerplants in the company's toy box, offering plenty of low-range torque and comical levels of thrust. Hell, it even makes the optional continuously variable transmission tolerable. Praise be to the deities of forced induction. But something has always been missing from the mix. From the first moment I got my hands on the Juke, I couldn't help but think how much better the machine would be if Nissan ditched an inch or two of ground clearance and sharpened up its suspension. Think more "hot hatch" and less "Kermit goes to Kroger."
