2015 Subaru WRX caught testing in US on Mulholland

In April, we got our first glimpse at the 2015 2015 Subaru WRX - the car was caught in STI form in photos and in motion running around Germany's infamous Nürburgring. That's all well and good, but obviously Subaru will sell a good number of the hotter Impreza models here in the United States, and thus, it's nice to now see a video of the next WRX testing out in California, albeit in what looks to be non-STI form.
Originally posted on the Subaru Owners Club website, this video comes from YouTube user 31200MulhollandHwy. And that's quite appropriate, since the video clearly shows the now de-winged WRX prototype testing on the well-known - you guessed it - Mulholland Highway. Just like before, we're disappointed that the prototypes spotted testing don't appear to be as bold and beautiful as the WRX Concept that Subaru brought to this year's New York Auto Show. Nevertheless, we'll hold our final judgments until the camouflage is peeled away.
Have a look below to see (and hear!) the 2015 WRX running up Mulholland.

2021 Subaru Crosstrek updated with new engine, refreshed styling

For the 2021 model year, the Subaru Crosstrek is getting some mechanical and aesthetic updates, along with a new Sport trim (pictured above). The biggest difference you’ll find for 2021 is the addition of a new engine to the lineup. While the base and Premium trims will continue to use the 152-horsepower, naturally aspirated 2.0-liter four-cylinder carried over from 2020, the Sport and Limited trims will employ a new-to-Crosstrek 2.5-liter four-cylinder boxer engine. Borrowed from the Forester, and also found in the Outback, this naturally aspirated 2.5-liter provides 182 horsepower and 176 pound-feet of torque. That power is put to the wheels via a continuously variable transmission (CVT) and SubaruÂ’s torque-vectoring all-wheel-drive system. The base and Premium trims, with the holdover motor, still come with either a six-speed manual or optional CVT. In terms of efficiency, the new 2.5-liter offers 27 miles per gallon in the city, 34 mpg highway and 29 mpg combined. The 2.0-liter still provides 22/29/25 mpg with the six-speed manual, or 28/33/30 mpg with the CVT — just one mpg better across the board than the 2.5. That aforementioned Sport trim is new to the Crosstrek, and it has more to set it apart than just the engine. ItÂ’s the only version with the dual-mode X-Mode system, with Snow/Dirt and the additional Deep Snow/Mud setting. Standard X-Mode — which essentially offers better traction in snow and dirt — with hill descent control comes on the rest of the CVT-equipped Crosstrek trims. The Crosstrek Sport also gets unique visual touches to set it apart from the other trims, like more prominent wheel arch moldings, dark grey 17-inch alloy wheels, and a gunmetal finish on the grille, side mirrors and badges. Inside, it gets StarTex synthetic upholstery, yellow stitching and other yellow accents throughout the cockpit, and gunmetal and faux-carbon fiber accents. Sport Trim exterior paint colors include new Plasma Yellow Pearl and Horizon Blue Pearl finishes. 2021 Subaru Crosstrek Limited View 9 Photos Speaking of looks, all 2021 Crosstrek trims (like the Limited pictured above) get refreshed grilles and an updated front bumper, with fog light insert covers on the base model, and other trims getting new fog light covers.

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.
