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 Forester adds a rear seat reminder, new pricing announced

The 2020 Subaru Forester has officially arrived with a few changes. To start, every Forester will be equipped with Subaru’s rear seat reminder as standard, following the larger 2020 Ascent which got that update earlier this year. Subaru is on the path to get the tech in all its cars, just like many other manufacturers have been doing for awhile now. ThereÂ’s a small revision to the standard EyeSight driver assistance tech for 2020. Now, every trim of Forester will be equipped with a Lane Centering function and a new Lane Departure Prevention function as standard. Previously, the standard equipment just included lane departure warning and lane-keeping assist.  Beyond those few tech add-ons, most things remain the same. A small increase of $200 bumps the price of entry up to $25,505. The destination charge was also increased by $35 to $1,010. All five trims from before are still available, including Premium ($28,405), Sport ($30,005), Limited ($32,105) and Touring ($35,605). The biggest trim-specific price increase comes at the Limited trim level, which went up $700 compared to the 2019 Forester Limited. You can read what we thought of the 2019 Forester in our first drive review of the redesigned model here. The 2020 Forester will be hitting dealers this fall.

Subaru nixes plans for US-built XV Crosstrek

Subaru is on a sales tear, with numbers up 21 percent through the end of November compared to last year. It's been investing in its Indiana factory, and having ended its contract to build the Toyota Camry there, the 400,000-unit capacity was once seen as more than Subaru needs. At some point Subaru had plans to build the XV Crosstrek here in the US, but Reuters reports that the company has changed its mind and will build the little crossover Scooby in Japan, in the same Gunma Prefecture factory where the Impreza, BRZ and Levorg are built. The report cites "the relatively high sales price," the weakening yen versus the dollar and capacity constraints at the Indiana facility. For a planned production run of 65,000 Crosstrek units annually, the new math – especially the yen valuation, which has declined against the dollar to a rate not seen since 2007 – makes Japanese production a viable option. Subaru isn't the only manufacturer taking its toys back home, either: the Reuters report says Toyota is considering shifting some Camry production back to Nippon, while Nissan plans to do the same with the Rogue. Our guess is that if Subaru sales continue the trend they've been on for years, the assembly decision will give them more local flexibility here for addressing it.
