Subaru Stars CVT vs. Manual

What is the best preference for your Subaru Impreza? I currently own a CVT and seem to enjoy the manual mode (Pretty much just auto clutch). I'd like to know what you guys prefer, in regards to enjoyment, response, and convenience.

It is all about preference. If you already own one, what's the point of asking? Anyways, to answer your question, I prefer the CVT. Why? Convenience. I have/do own a 6 speed manual S2000. My fiance/future wife can't drive stick, and she sometime needs my car. The CVT gets better MPG and according to Subaru, the CVT is the better AWD system than the manual 50:50. In terms of enjoyment, I wouldn't say this car is soul crushing. But, it is nothing compared to a S2000. Response, I feel as if the CVT is "preppier" off the line in city driving compared to the manual.

TL;DR: CVT b/c future wife can't drive stick and mpg.

My current Impreza CVT is the first automatic that I have owned in nearly 20 years...I hate it. My wife's Outback 3.6R is a traditional automatic...I hate it moderately less.

If my new commute was not 70+ miles a day on crowded urban highways, I would certainly have a manual transmission. That said I got really tired of riding the clutch in traffic jams every day, so my CVT serves the purpose...even though it is definitely soul crushing.

I wanted a manual, but the dealer said they'd have to order it from Japan, taking at least 90 days to arrive.

The CVT is fine. The paddle shifters are great for wringing all the performance out if this engine for spirited driving, and normal CVT mode is great for lazy driving, simply to get from A to B. I have no issues with it. Supposedly it's more durable than a traditional auto too.

What was that comment about the CVT-equipt models having a better AWD system?

CVT supposedly has a 60/40 split between front and rear wheel where Manual has a 50/50

So i would guess the Manual has the better awd system.

2014 XV Crosstrek

Default

I've got a 2014 XV Crosstrek with the 5spd manual. It's definitely love/hate with this transmission. I've owned many 4 and 5spd manuals years ago and most were much nicer shifting vehicles than my new XV.

With my previous ride having been (a leased) 2012 Legacy 2.5i CVT, I do somewhat regret not getting the CVT again. That was an excellent drivetrain and I couldn't say enough positives about it having clocked ~3yrs/43K mi on my Legacy CVT.

The reason I went with a 5spd XV was, it happened to be on the lot and a color I wanted. It was a little cheaper to buy and I thought it would be fun. It's not that fun.

It is supposedly better because the CVT's system has electronic clutches which can transfer power faster and more efficiently than the manual's.

Yes, it's probably better from an efficiency standpoint being a more reactive system as opposed to the 'dumb' constant 50/50 system the 5spds have.

The pluses on the 5spd is, it's a simple mechanical system and one gearbox full of 75w90 gear oil lubricates the whole system; gearbox, front diff, and T-case. The 5spd has a gear oil dipstick and a drain plug. Real easy DIY maintenance.

The CVT uses the blue liquid gold CVT oil and a LOT of it, then has a separate internal reservoir for the 75w90 diff gear oil. The CVT portion is "sealed" with drain and level check plugs. Atleast they were in 2012 when I owned my Legacy CVT and the diff oil has a drain plug, level check plug and is filled through the breather tube hole.

CVT is variable, and is likely more 90/10 than 60/40. But someone will post the 10 year old Subaru of Canada marketing material soon trying to debate that.

According to Outback owners on their forum, who owned and drove Outbacks with both systems, viscous coupler (MT) and the electronic clutch (Automatics), they thought both systems worked great, but the electronic clutch system responded marginally faster (slippery back country roads, ideal test conditions for each).

Re. the AWD system:

The manual is 50/50 on dry roads under normal conditions. According to AWDWiki.com, it can go to 80/20 either way when necessary. It uses a limited slip center diff with a viscous coupling to do this. The coupling takes a moment to react to wheelspin, so it doesn't react with the same immediacy as the electronically controlled CVT system.

There's conflicting information out there from various sources about the CVT system. AWDWiki says it's 60/40 under normal conditions, Subaru of America was saying for a while that they can't give a real answer, since it's constantly varying based on road conditions, and someone or another says it's more like 90/10 under normal conditions. The electronically controlled system is able to respond to slippage more immediately than the mechanical/hydraulic system with the manual.

I have 13 impreza manual, last weekend my fiance got 14 impreza CVT
I drove her car and it felt like somewhat slower than my car, but paddle shift was fun.

I believe you give up 1 second in 0 to 60 mph comparisons with the CVT (that is, 8.5 seconds for the MT vs. 9.5 seconds for the CVT).

The drive systems aren't comparable in their workings. Differentials split torque, clutches transfer torque.

CVT:
-Operates like a variable 4WD system.
-No center differential
-Multi-plate clutch
-No fixed torque "split"
-Front wheels never lose power
-100% of power transfer to rear is computer controlled
-Clutch allows one way power transfer to rear

5MT:
-True AWD system
-Center differential AND viscous coupling
-50/50 initial torque split
-Center differential powers both front and rear axles equally
-Viscous coupling is the reactive element
-VC transfers power between front and rear axles
-Initial 50/50 split makes traction loss less likely in the first place
-Slight rear bias through cornering by VC
-Bidirectional front/rear power transfer by VC
-Front/rear symmetry

For mountain driving, the CVT is fantastic. It can choose the optimum gearing for any incline, and it makes adjustments easily. For that reason, the CVT also delivers great gas mileage in the mountains. Just don't use cruise control when going up steeper grades; that often sends the CVT into a panic.

While we all discuss the differences between the 2 systems just know that the people with the 5 speeds are talking with 1k dollars in their pocket because of their choice.


Winners.

I drove a 2015 WRX premium CVT and bought a 2015 WRX Limited 6-spd. I've always preferred manual transmissions.

The shifts under WOT are meh after owning a Mustang 5.0..
The CVT was super smooth and could really utilize the turbo to great effect.

I bought a manual. Why? Aside from the ancient argument between manual vs. automatic.. the CVT was boring.. and couldn't predict turns very well.

I could've lived with either.

Yes indeed. On my last vacation around the desert southwest, by far, my best MPG was in the Rockies, when I was fully in the Rockies. In the mountains I could easily get 50+ mpg, 53 mpg was my best over ~300 miles one leg. On the flat, my best has been 44 with absolute perfect conditions, and normally being 38-42. My downhill stretches in the mountains more than made up for the uphill ones. I also didn't push it very hard uphill, I took it nice and easy not feeling the need to make it go above ~50 mph (a happy place for the car going up the mountain passes, La Veta, Wolf Creek, etc.).

This is all of course on summer gas, warmer temperatures (early fall in the Rockies)

There is a bushing kit for the stick that is supposed to make the gates better and the shifter not so sloppy. This one is the first auto I have bought for myself in 20 years, so far so good. I like the paddle shifters.

For me, the actual gate and throw of the 5spd is great. It's the occasional not so smooth take-off and whip-lashy 1-2 and 2-3 that are absolutely frustrating.

Like I say, I've owned many manual trans vehicles in the past (I think 7 all together?). Cars, light trucks and SUVs. Pretty much all smooth as butter compared to my 2014 XV Crosstrek 5spd.

That has more to do with your driving than the gearbox. The throttle by wire requires a different technique.

Problem with that is, I've driven other E-throttle equipped vehicles with 5 and 6 speed manuals. Smooth as butta. This was with the first time driving them.

Different all together, but I shuttle tractor-trailers around the plant at work. Most lately are Volvo or Freightliners with 10spds. Very little drama with those.

I have the CVT and really like it. It's not as involved as a stick but it's infinitely better as a DD IMO.
I love the smooth and effortless shifting in normal mode while commuting.
If I want to be more involved the paddles are there and work pretty well. It's not a DSG lightning quick shift but is acceptable. I really like it in the mountains and twisty roads where it rev matches ready to surge out of a corner. I think 3k - 5k rpm driving with the CVT is quite spirited and I use the paddles all the time to engine brake. Pretty sure I'll never go back to stick unless racecar.

Agreed, except I'd say 4k-6k. That's where all the "get up and go" is, IMHO. Hopefully revving near redline isn't bad for these engines, as long as it's at proper operating temperature and has the correct oil in it.

Driving the 5MT in a 2012 Premium Sedan. We've always had manual transmissions, just can't do automatics.

A friend has a CVT version and comments about the CVT being noisy, make that whiny. The 5MT is silent and smooth as silk.
