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.

2023 Japan Mobility Show Mega Photo Gallery: All the highlights and reveals from Tokyo

The 2023 Japan Mobility Show managed to serve up a surprise heap of exciting and futuristic designs and production reveals. Our staff was on the ground in Tokyo for this year's show, where we captured not just all of the latest automotive trends, but some genuinely weird and fascinating stuff.  Browse: Some Delightful Oddities of the 2023 Japan Mobility Show But on to the cars. This year's show featured introductions from Daihatsu, Honda, Lexus, Mazda, Mitsubishi, Nissan, Subaru, Suzuki and Toyota. Some are weird; some are wild; most are probably destined to change significantly before production or merely fade into the void with the rest of the industry's vaporware, but if even a few of these make it to showrooms, we'll consider it a win. Scroll on down for our live galleries of each of the show's major debuts (and cars we're only now seeing in person for the first time).

Best. Year. Ever. Subaru breaks yearly and monthly sales records in 2017

After a generally good sales year for most car manufacturers, one company had a spectacular year: Subaru. The company reported with its end-of-year sales that 2017 was it's best sales year of all time. The total was 647,956 vehicles sold over the 12 months. Not only that, but December was also the best month of sales the company has ever seen with 63,342 cars sold. That's nearly 10 percent of the annual sales in one month. As far as individual models go, the Impreza and Crosstrek each had their best month in December and 2017 was each model's best year. The Impreza's year was especially impressive with sales jumping more than 55 percent compared with 2016. It was also the best year for Outback. Subaru credits some of its strong December to its "Share the Love" promotion that donated $250 of each new car purchase to one of a selection of charities. But a big part of Subaru's sales success has to be due to the fact that most of its products are in the hottest car market around: crossovers. The fact that its products are highly competitive against other similar vehicles certainly helps too. This is partly evident by the fact that year-to-year, every crossover model with the exception of the aging Forester saw a sales increase. Meanwhile, every traditional car (Legacy, WRX/STI and BRZ) with the exception of the redesigned Impreza had lower sales for the year. So if you ever wonder why companies aren't racing to release new sedans and coupes, this is why. Related Video: This content is hosted by a third party.
