2020 Subaru Outback Suspension Deep Dive | More than meets the eye

The 2020 Subaru Outback is a completely redesigned car. It has a lot to offer in terms of new convenience features, and the driving experience is much improved. A good deal of that comes from chassis improvements, and indeed a lot of work went into making the body shell and suspension subframes more rigid so the suspension attachment points could be more robust and stable. Don’t let all of that rigidity talk make you think the ride itself is stiff. It isnÂ’t. Any suspension tuning engineer will tell you that a stable platform is necessary even if a smooth ride is the goal. Rigid attachment points make it easier to control ride motions and road imperfections within those components designed for that very job – the springs, dampers and suspension bushings. So letÂ’s take a look at what Subaru has done under the new Outback. What weÂ’re about to see doesnÂ’t just apply to the Outback wagon, but to the closely-related and also-redesigned 2020 Legacy sedan as well.   ItÂ’s no surprise that a vehicle like the Subaru Outback uses strut front suspension, but from here, a couple of details do look curious.   Like any strut suspension, the steering axis (yellow line) is defined by the pivot bushing at the top of the strut and the center of the lower ball joint. The entire affair will pivot about this line when the wheels are turned. The lower control arm (red) of the newly redesigned 2020 Outback is now a lightweight aluminum piece instead of the steel hunk that was used last year. As before, thereÂ’s a “direct-acting” stabilizer bar link (green) that attaches to the strut housing, an arrangement that maximizes the efficiency of the stabilizer bar because the motion ratio is 1-to-1 motion with respect to wheel movement. As for the stabilizer bar itself, itÂ’s now hollow to save a bit of weight.   This spacer (yellow) raises the body relative to the suspension. The Outback has one, but the lower-riding Legacy sedan does not. The spacer pushes the arm down (or the body up - take your pick), so that means the OutbackÂ’s reinforcing bracket (green) will also differ from that of the Legacy. While weÂ’re here, look at the round rubber bushing just below the spacer. That void space and square nub you see pointing directly at you will make sense in a short while.   Subaru couldnÂ’t simply put a spacer on the OutbackÂ’s rear lower control arm pivot and call it good. They had to do something of similar magnitude at the front.

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.

Best-selling vehicles by state

America loves trucks. According to Edmunds, which has tracked the best-selling vehicles by state based on new vehicle registrations, 40 out of 50 U.S. states’ best-selling vehicle is a pickup. Most often, thatÂ’s the Ford F-Series, but occasional Chevy, Ram and even Toyota top the lists. Here, weÂ’ve compiled the best-selling vehicles by state, including the four runners-up for each state. Interestingly enough, only one EV shows up in a stateÂ’s top five (Tesla Model 3 in California). Read on below to see whatÂ’s most popular in your state.
