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.

Scion rules out roadster, turbo versions of FR-S

Ever since Toyota and Subaru released the sports car alternatively known as the GT86, 86, BRZ and Scion FR-S a couple of years ago, rumors have circulated that even more exciting variants could be in store. But at least as far as Scion is concerned, those rumors are apparently nothing more than wishful thinking. Speaking with WardsAuto at the LA Auto Show last week, Scion chief Doug Murtha said that the prospect of an FR-S roadster has been taken off the table entirely. Apparently Scion lobbied parent company Toyota to produce just such a model, but after failing to find other markets interested enough in the model to put it into production, corporate HQ said no. "I think we were pretty aggressive on our (submitted plan), but we looked at what we would have conceivably lost on the product and said, 'We're not going to even push it further,'" Murtha said, going on to note, "Nobody was more disappointed than we were." Murtha further shot down the idea of a turbo version of the FR-S, dismissing it as a prospect the blogosphere (that's us) wanted to happen but "that's not something that's coming." Either variant might have helped Scion and Toyota boost sales of the model (which are predictably dropping after their first two years on the market), but the investment also might not have paid off their development, tooling and marketing costs. Of course, Murtha can only speak for Toyota, but we'd be surprised to see Subaru go it alone on either model, as costs would be that much more prohibitive without a partner. Bummer.

Toyota and Subaru file patents for performance FR-S and BRZ

People have longed for a more powerful version of the Subaru BRZ, Scion FR-S, and Toyota GT86 since the triplets arrived on the market. So far, neither partner in the deal has launched a model to fully satiate that hunger. However, the Japanese patent office recently approved documents from Toyota for the design of a vehicle that looks just like the Subaru STI Performance Concept (pictured above). According to AutoGuide, the filing also gives Fuji Heavy Industries credit for the design. The STI Performance Concept debuted at this year's New York Auto Show as an early step in STI's attempt to expand its reach here. The BRZ-derived coupe featured a body with a ground-scraping front bumper, tweaked headlights, wider fenders, a massive rear wing, and diffuser with a center-exit exhaust. All of these elements also show up on the patent renderings. The concept was just as exciting under the hood because STI installed a 2.0-liter, turbocharged boxer four-cylinder from its GT300 racer, and upgrades for the chassis, suspension, and brakes came from the Japanese market's BRZ tS. While the coupe made hearts race, the company was clear it didn't necessarily plan to build the model. Patent filings aren't a guarantee for production, and even if this one does arrive in showrooms, it might not come to the US. That's because Subaru and Toyota have a history of creating Japan-exclusive versions like the tS or Style Cb. That being said, spy shots have revealed a camouflaged GT86 testing in Europe, and rumors indicate more power from the engine. Subie's boss has even confirmed the existence of a partnership to create a next-gen model. Related Video:
