Subaru teases Viziv Adrenaline Concept crossover for Geneva

The latest installment in Subaru's Viziv line of concept vehicles is set for a reveal at the Geneva Motor Show next month. It's called the Viziv Adrenaline, and it'll add to a pair of electrified "e-Boxer" models on display, possibly the e-Boxer version of the Forester and a Crosstrek plug-in hybrid, which is branded as the XV in Europe. We're limited to this darkened, front three-quarters view for clues about the Viziv Adrenaline. It appears to be a two-door, raised crossover with bulging quarter panels, an interesting undulating belt line and plenty of creases for a rugged look. It also appears to sport futuristic-looking rearview cameras in place of conventional mirrors, and the LED headlights look pretty close to the ones found on last year's Viziv Tourer. Also, two cutouts at the top of the hood may indicate the presence of a combustion engine. Given that this is called the Viziv Adrenaline, are we looking at a performance model? Viziv is Subaru-parlance for "Vision for Innovation," so there are doubtless more details in store for us in Geneva. Last year's Viziv Tourer Concept presaged a production WRX wagon, and the Viziv Performance Concept from 2017 previewed a possible future WRX (don't forget the Viziv Performance STI Concept from last year's Tokyo Auto Salon). While Subaru has given us reasons to be wary about its concepts' ties to future production models in the past, don't forget the Viziv-7 did indeed become the Ascent three-row SUV. The Viziv Adrenaline debut is scheduled for March 5. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

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.

Hi-po Toyota GT86 to get KERS?

We happen to like the Toyota GT86 - and, it of course goes without saying that the same applies to the Subaru BRZ and Scion FR-S, as well - just the way it is. Yes, that includes the standard 2.0-liter four-cylinder boxer engine and its 200 horsepower at 7,000 rpm.
That said, a little extra power never hurt anybody, right?
The most obvious way to add some punch to the GT86 would be with a turbocharger, and that has indeed long been rumored for an STI version of the BRZ. Will Toyota follow suit? According to Top Gear, the answer is no. Says GT86 chief engineer Tetsuya Tada, "I think 300bhp with a turbo and 200g/km of CO2 would be tasteless in this day and age. And a turbo would mean the loss of the GT86's uniqueness." Perhaps a bit harsh, but there you go.
