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.

Most reliable cars in America

For many people, the absolute worst thing they could experience with a car is for it to break or have a problem. The good news is there are cars that will ease the anxiety of their owners with infrequent trips to the shop. According to Consumer Reports, using data from its annual survey of subscribers, the following ten vehicles are the most reliable in the country, and are ordered from most to least reliable. Any of these vehicles should be a solid choice if the most important consideration in your car-buying decision is predicted reliability. That said, they aren't all vehicles that Autoblog's editors would recommend as fun to drive. We've provided links to our own driving impressions on these vehicles where possible. Also, if you care more about overall brand reliability than individual nameplates, check out the list of most reliable car brands. 10. Mazda CX-9 This three-row Mazda straddles the line where luxury begins and ends. It’s also pretty fun to drive for a family hauler. The fact that itÂ’s reliable to boot makes this an easy SUV to recommend. 9. Subaru Crosstrek Few vehicles define a segment quite like the Subaru Crosstrek. ItÂ’s a good buy, with class-leading ground clearance, tall seating position and good visibility, a surprisingly spacious cargo area, and multiple driving modes geared toward inclement weather and dirt roads. According to CR, it also sees fewer trips to the shop. 8. Toyota Highlander It wouldnÂ’t be a reliability list without at least one Toyota on it, and indeed the Highlander isnÂ’t the sole Toyota here. We especially like the Hybrid for its excellent fuel economy, but CR didnÂ’t break out its reliability list by powertrain. 7. Honda Insight The Honda Insight is a handsome, comfortable and affordable hybrid sedan. ItÂ’s also quite safe, and, according to CRÂ’s data, reliable. 6. Mazda MX-5 Miata Any Autoblog editor will happily profess their love for this Mazda MX-5 Miata. ItÂ’s an incredibly engaging roadster — at least when equipped with a manual transmission — that behaves a lot like the classic British and Italian roadsters of yesteryear. Thankfully, it doesnÂ’t share its European forebearsÂ’ penchant for breaking. 5. Cadillac XT5 One of the newer nameplates on this list, the Cadillac XT5 is also a hot seller for the American luxury brand. ItÂ’s also CadillacÂ’s most reliable vehicle. 4. Toyota Prius The Prius has been the face of Toyota efficiency for years now.

Subaru Crosstrek Baja Racer is a glorious blue and gold liveried masterpiece

Subaru just revealed its new Baja racer, and it's the coolest one yet. The Crosstrek Desert Racer is now sporting Subaru's traditional blue and gold livery that we all know and love from the many years it was plastered on Impreza-based rally cars. It's hard not to be nostalgic on this one, and we just had to share it. This Crosstrek, which bears about zero resemblance to an actual Crosstrek, is being run in the grueling Baja 500 off-road race through the Baja California Peninsula. Crawford Performance and Grabowski Brothers Racing are running the show, hoping to improve on their second-place finish from last year. The vehicle has a 2.5-liter naturally aspirated flat-four engine built to produce 300 horsepower. It's great to see Subaru continue to expand the blue and gold livery theme to more motorsports efforts. At the 2019 Detroit Auto Show we got to see the same livery on an STI rally car destined for competition. Now this beast of a Baja racer looks ready to strike fear into the hearts of its opponents just the same. The vehicle itself is rather insect-like in nature with the suspension and lights sticking out everywhere. There's still no word on whether the team will try for the big Baja 1000, or just stick to the 500 for 2019. Regardless, it looks supremely capable, and must be an absolute hoot to drive.
