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.

2014 Subaru Forester XT

Power Doesn't Come Cheap
When Subaru first offered a turbocharged Forester XT model to US customers for the 2004 model year, the shoe-shaped second-gen model fell into a ready-made competitive set of small, V6-powered crossovers and SUVs. The XT might have been more of a raucous shopping-trip companion than, say, a Ford Escape V6, but the basics of the cars offered a clear differentiation from the naturally aspirated, four-cylinder models found just a bit downmarket. Here in 2013, the V6 breed of crossover in this size class is all but extinct, and turbocharged four-cylinders with the power to compete with the XT are not thick on the ground.
In many ways, the comparative analysis gets most interesting when you start looking around for CUVs to match up with the all-boxes-ticked Forester XT Touring that we had as a tester for a recent week. The top of the line Touring trim means that the Forester comes with features like 10-way power seats, leather, navigation, a Harmon Kardon sound system with HD radio, Bluetooth and more. In fact, our Forester also had the only option package available on the XT Touring; one that included keyless access, HID headlights and Subaru's EyeSight system (adaptive cruise, lane departure warning and pre-collision braking).

Was the old one better? 2019 Subaru Forester joined by past generations

NEW YORK — Are you having a hard time telling the all-new 2019 Subaru Forester apart from its predecessor? Are you wondering what was actually changed? Well, it's as if Subaru sensed that confusion, and brought the new Forester's ancestors on stage for its debut here at the New York Auto Show. Honestly, it didn't help much. The rear looks considerably different thanks to its Honda Accord-like forked taillight treatment, but oh boy, is there a strong similarity between generations four and five. However, given the success Subaru has been enjoying these past few years, why mess with something that works. After all, the new Ascent looks the way it does because that's what Subaru customers expected. And now, Subaru Forester, this is your life. Which is your favorite? Generation 1: 1997-2002 Generation 2: 2003-2008 Generation 3: 2009-2013 Generation 4: 2014-2018 Generation 5: 2019 View 19 Photos Related Video: New York Auto Show Subaru Crossover SUV
