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.

2020 Subaru WRX and WRX STI Series.White sneak in one more special edition

LOS ANGELES — This generation of Subaru WRX and WRX STI is nearly done, and has celebrated with special versions here and back in the home country. But the company isn't finished with limited edition models yet, as proven by the 2020 Subaru WRX and WRX STI Series.White model (their punctuation, not ours). Just like past Series.Whatever models, the Series.White is distinguished on the outside by an exclusive Ceramic White paint scheme. It's accented by black mirror caps, black badging and matte bronze wheels. On the WRX, they're 18-inch wheels from Subaru, and the STI gets 19-inch BBS wheels. The paint color isn't the only perk, as each car comes with a selection of desirable options. The WRX basically gets the Premium trim's Performance Package, plus a few goodies. That means it gets Recaro seats, Brembo four-piston front calipers and two-piston rear calipers, LED adaptive headlights, and the sunroof is deleted. It also gets a special Bilstein suspension setup that hasn't been offered on the WRX before. The WRX STI gets a Bilstein suspension, too, as well as Brembo six-piston front calipers and two-piston rear calipers, Recaro seats, stiffer steering rack mounts and Michelin Pilot Sport Cup 2 tires. Neither model gets any extra power, though. Subaru will only build 500 examples of each model, a total of 1,000 cars. The WRX Series.White has a price of $34,895, and the WRX STI costs $43,595. These special Subarus go on sale next year.
