Why Subaru’s CVT Is The Most Misunderstood Feature On New Forester And Crosstrek

Why does Subaru use a CVT automatic transmission in the 2021 Forester and Crosstrek? See why it’s one of the most misunderstood and the best drivetrain feature.

We know we’ll get a negative response from this report. Still, the Subaru Lineartronic CVT (Continuously Variable Transmission) automatic gearbox is one of the best features on the 2021 Forester, Crosstrek, Outback, and Ascent SUVs. It’s probably the most misunderstood part of the drivetrain and despised by most automotive “experts.” But when used correctly, it’s a feature that ramps up driver engagement.

The CVT automatic transmission is criticized most because they are high revving, noisy, and slow to accelerate once the car is moving. In most cars, this is true. Subaru pairs the Boxer engine with the CVT automatic for its fuel-saving capabilities. The CVT uses a step-less gear ratio that allows the engine to run in its optimal power range, no matter what speed you maintain, for improved fuel economy and performance. But Subaru adds two misunderstood features.

But Subaru adds a manual mode function with steering-wheel-mounted paddle shifters that allow the driver to select seven or eight preset ratios depending on the model. Most automotive journalists don’t take the time to understand, and most importantly, use the system correctly to maximize the Lineartronic CVT’s abilities.

They leave the transmission in automatic mode, eliminating the need to shift and let the Lineartronic CVT adjust to match acceleration. But they let one of the best attributes of the Forester, Crosstrek, and Outback go unused.

The 2021 Subaru Forester Sport, Limited, and Touring models use a Lineartronic CVT with Adaptive Control and a 7-speed manual mode with steering wheel paddle shifters. All 2021 Subaru Outback trims come with Lineartronic CVT with Adaptive Control and an 8-speed manual mode with paddles.

The 2021 Crosstrek Sport and Limited get the automaker’s newest Lineartronic CVT with Adaptive Control, Incline Start Assist, and 8-speed manual mode with paddle shifters.

In 7-or 8-Speed Manual Mode, paddle shifters are mounted near the top of the steering wheel for easy “fingertip control,” giving the driver the ability to select the gear ratio that suits the driving situation. The result is a sharper and sportier driving experience. But many automotive journalists are either too lazy or fail to learn how to use the paddles correctly.

They let the transmission sort everything out on its own by default and then complain because it doesn’t “shift” like a conventional automatic transmission. But Subaru’s Lineartronic CVT manual mode combined with the steering wheel paddles are a unique feature for drivers who take the time to understand how it works.

The CVT, manual mode, and paddles work in concert and are an excellent option to have in a performance context. The driver can “downshift” with the left paddle and bump the shifter on the center console left to lock it into manual mode. The two features give the informed driver a high level of engagement and control over the transmission’s behavior, as you’ll find in more expensive sports cars.

The Subaru Lineartronic CVT automatic gearbox is one of the best features on the 2021 Subaru Forester, Crosstrek, Outback, and Ascent SUVs when appropriately used.

I'm a life long manual transmission user but a few years ago rented a Subaru Legacy for a vacation trip up the Olympic Peninsula. I discovered the paddle shifters after a bit and used them extensively going through the mountains. It was one of the best driving experiences I've had in a rental car. While I prefer a manual (as in my 2018 Forester), the eventual (forced) transition to a CVT probably won't be as bad as I once feared.
meh I have a 2018 Legacy and the CVT sucks. The paddle shifters are pointless and do nothing but pinch your fingers when you're gripping the wheel. Car is so slow off the line and the engine groans.
I had never driven an automatic until I bought the crosstrek in 2013. The CVT is an excellent transmission. It is always in exactly the right gear for the throttle position selected. Yes, that means that it revs high, the optimum number for the conditions. Auto writers seem to hate them but I don't have any idea why. I really enjoyed the paddle shifters. I have since purchased a car with a normal automatic, 9 speed, and the crosstrek was much better. Smoother, better gas mileage, and I really miss the paddle shifters.
This reads like a paid advert. Is it?
Is what you are calling "adaptive control" the adaptive cruise control?
All cars that use CVT should have paddle shifters or ability to select to select lower gear ratios, like conventional automatics, for better control on downhills. The braking mode on many CVTs is only good for lower speeds, at higher speeds, too much braking is added. If Subaru was really concerned about driving experience, the paddle shifters would be across the board, not just on higher trims.
I think you're talking exclusively about the Forester as this is the only model still excluding paddle shifters on some of the trim levels (at least as far as I recall). I believe Subaru's view of Forester customers has been that they are generally older (especially since the front section of the doors double as hand-holds for getting in and out) and the Forester buyers didn't want anything complicated. So unless customers were getting the performance version (XT) then any unnecessary complications were avoided. I started leasing Subaru's in '14 and for the longest time I wouldn't get my wife a Forester because it only had a "Drive" and "Low" mode for the transmission (which drove me nuts, even if I was only using her car once in a while). She ended up with a couple Crosstreks instead until we finally had to upsize to a '17 XT (wanted a 2.5 but got the XT because it had paddle shifters and they are indispensable in the mountains). So I think keeping it simple was what took them so long to bring any paddle shifters into the Forester lineup. I believe it was the Black Edition in '18 that was the first naturally aspirated engine with a CVT and paddle shifters, but much like the 2021 Crosstrek Sport it was very limited in the options you could get and I remember considering it for my son, but it was more of a dumping ground for their old technology than anything else. So even though every other model has already had paddle shifters in every trim for years, the Forester is only now catching up, but Subaru is still "giving the customers what they want" with certain trims and I think more than anything the company is saving money for as long as possible by not including them.
My favorite characteristic of the CVT in my Outback 3.6r is when driving up long mountain grades like I-70 Eisenhower Tunnel approach in Colorado. Since the CVT can choose any gear ratio to maintain speed, it never lurches to downshift like automatic transmissions nor do you end up having to choose between 2 not-quite-right manual gears. This means that the engine doesn't rev too high or low and just smoothly drives up whatever grade.
The use of the "manual" mode in snow and ice is necessary to keep the transmission in a lower gear to maintain traction and forward progress.
I disagree. Turn off VDC and mash your foot down when you want to spin the wheels, or on the newer cars the Deep Mud/Snow setting lets the wheels spin a bit instead of cutting the throttle to maintain traction without wheel spin.
This article was a poorly written fluff piece. It's true that the Subaru CVT is a good transmission and it does work well, we've owned 3 of them; all the high torque versions from the WRX and 3.6R, but to say that automotive journalists don't understand how it works or have never seen paddles before is ludicrous. Calling manual mode a "feature" is even a stretch. Most automatics, whether they are traditional gears or CVTs allow you to switch to manual mode. It's a basic function of all these transmissions. The takeaway here is: don't hate on the CVT, it's just as good as other automatics. The way it was presented was like there was nothing else to write about today.
I don't even own a Crosstrek, but whenever I drive one I typically use the paddle shifters. Even in automatic mode, I feel like the CVT is plenty responsive and the drive-terrain is peppy for only 150+ hp in the 2016. Pretty impressive vehicle for the price. I might be buying one or a Lexus NX 200t. Mileage in the Crosstrek is tough to beat tho.
Have a 2019 Forester Sport with about 23,000 miles on it. I've generally found the CVT to be enjoyable and can manage as high as 35mpg with a full (like evacuated my home FULL) car if I'm taking it real easy and sticking to about 70 on the freeway. More average is about 30mpg though with my mountain driving. I use my paddle shifters all the time to help keep me at a good engine braking level or for more spirited driving. I also found that sometimes coasting downhill more than 1 or 2 degrees will initiate some engine brake, but if you want to just coast and gain speed, toss it in manual mode and your highest gear to override that. I did notice though that my highest gear still isn't as high as the CVT can go in auto-mode (by about 200-300 RPMs). Maybe I am missing a weak point in the CVT, but couldn't it also be setup with an x-mode only range of gearing below "1st gear" in lieu of a transfer case?
Are you kidding? Worst article... how much time did you really spend on this?
I've had CVTs in '14, '16, and '18 Outbacks (also 6 other '14 and later Crosstreks and Foresters for my wife) and they have all been great. Most people that complain about them haven't driven them. The worst "feature" is the ridiculously annoying and power-sapping "fake shift" they added because of all the whining from people that don't realize how CVTs work. My '14 Outback was super-smooth and always had the optimum engine speed during hard acceleration, but the '16 had the fake shifts added and was beyond annoying until I figured out how to avoid them. I've been writing to Subaru ever since to lobby for it to be a software selectable option. I found in both my '16 and '18 (both 3.6Rs) that if I keep the RPM below 3,000 when accelerating then the fake shifts don't happen and it is much less annoying while still pulling quite well.
I agree, I have a 2018 Forester 2.5 and as long as I don't "floor it" and drive it "normally", it works just fine....only if I try to drive aggressively with lots of "flooring the pedal" then its OK...a 2.5 Forester was simply not designed to drive aggressively, so if people keep in perspective what the vehicle is designed for, they'll be OK with it I think...
I have a 2018 Forester...first vehicle I have owned with a CVT. The thing I have learned about driving my Forester is that the CVT works fine when you drive "normally" Accelerating at a models pace from a stop and general stop and go driving as well as the occasional passing maneuver all work well. If you like to drive a vehicle "hard and fast" with lots of "Jack-rabbit" full-throttle starts and lots of flooring the gas pedal, you are not going to like the CVT...this tranny is not designed for aggressive driving...if you drive normally and "conservatively" you will be just fine with a CVT.
