Nissan-Renault mule teases mysterious subcompact

There's always something intriguing about a mystery, especially of the automotive kind, and that's exactly what we have here. Our spies recently spotted this Nissan-Renault test mule on the road in Southern Europe. But what, exactly, are they testing? From the front end, it's clear this mule started life as a Nissan Versa Note, but check it out in profile to see the cut down rear doors. They're significantly shorter than on the production car, and the wheelbase isn't as long here, either. The tacked on fender flares suggest a wider track than stock, too. Making things even more complicated is the bizarre cladding this subcompact hatch is wearing. The odd tumors on the hood and blistered side panels indicate that the automaker is trying to keep the design underneath a secret. Given Renault and Nissan's tight relationship, it also isn't clear which company is testing this model. While the body comes from the Note, this one is wearing French license plates. According to our spies, the vehicle was also spotted leaving a Renault testing location. There are some possibilities, though. Renault already has the new Twingo out, and the next-gen Megane has an imminent release. The French brand could now be at work on a future Clio. Alternatively, Nissan is reportedly using the Sway concept as inspiration for the upcoming Micra, and we could be getting a preview here. Give us your best guess in Comments. Related Video:

Nissan Murano production fires up in America for first time [w/video]

Production of the new, third-generation Nissan Murano has finally kicked off at the company's Canton, MS factory, marking not only the eighth vehicle built on the facility's lines, but also the first global product to be built there since it opened in 2003.
"The strategic investments that Nissan has made in Canton serve as a testament to the flexibility, efficiency and talent of our workforce and suppliers," said John Martin, Nissan's boss for manufacturing, supply chain management and purchasing. "In Canton, we build high-quality vehicles that compete and win globally, and the bold new Murano will build on that reputation."
The addition of Murano production, which joins Altima, Armada, Titan, Frontier, Xterra and NV, brought a further 1,300 jobs.

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.
