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.

1992 Subaru Libero | eBay Find of the Day

The annals of history are filled with some pretty strange vans. Here in the U.S., we've seen such oddities as the Stout Scarab and, more recently, the mid-engine, supercharged, all-wheel-drive Toyota Previa. In other parts of the world, things have gotten even more interesting. Take this Subaru Libero for instance. A 1.2-liter three-cylinder engine means it isn't a Kei car, despite the van's diminutive dimensions. That engine is mounted at the rear, and it sends 73 horsepower to all four wheels through a five-speed manual transmission. This particular Libero is far from perfect, but it shows just 14,000 miles on the odometer and you're not likely to see many others like it here in the States. The high roof with its trio of glass panels keep things light and airy inside, and its massive rear hatch makes all that space inside extremely accessible. Sure, it's not a camper, which means its owner won't be living that hashtag-vanlife. But it offers a lot of space for its size, so it might be the perfect promotional vehicle for a local delivery business or the like. At the very least, this little Subaru Libero would definitely strike up lots of interesting conversation at your local Saturday-morning hangout, and that's what's really important, right? It's currently for sale on eBay with a Buy It Now price of $9,900 and located in Philadelphia, Pennsylvania.

Don't expect an all-new Subaru WRX until 2020

Despite Subaru completely overhauling the Impreza for 2017, it appears the WRX will stick around on its current platform for another few years. That's the word from Motoring in Australia, who spoke with an senior engineer from Subaru about a WRX replacement. For those that can't wait, the good news is that a WRX refresh is coming for 2018, which should carry the car for another few years. It should be no surprise that a full WRX redesign is a few years off. Although the fourth generation Impreza was released in 2011, the current WRX has only been on sale since the 2015 model year. Given an average five-year cycle, we can most likely expect a redesign for 2020. It's not clear how extensive the refresh will be or if the STI will finally drop the ancient EJ-series 2.5-liter turbocharged flat four engine for the more modern FA-series 2.0-liter turbocharged flat four engine found in the regular WRX. Rumors have been swirling for years of what else a full-redesign may encompass. The current model was rumored to have an electric turbocharger that obviously never appeared. There have been other rumors of a switch to a hybrid powertrain. While that may work when the WRX finally uses the updated Impreza platform, don't expect to see hybrid power in the refreshed model. Subaru says the time it would take to engineer such a system would be too great to have it available for 2018. The new Impreza's platform is designed to fit a hybrid system, so don't rule out the possibility of a WRX hybrid.
