Default Question on new 2010 Impreza

I'm looking at possibly buying a new '10 Impreza 2.5 (slow 170hp) 4dr.

My main question is about the different AWD systems on the 4speed auto and 5 speed manual. I'm leaning towards the automatic since my wife will be able to drive it and I've done enough rowing through the gears in my life.

I understand the 5 speed manual has a viscous-coupling locking center diff and the 4 speed automatic has an electronic controlled variable transfer clutch.

Is one better than the other? I'm mainly concerned how the car will do on ice and snow, since I'll be driving on it for 6-7 months out of the year. Will the 4 speed automatic be able to get out of snow with only one tire having traction? I run winter tires, so I'm just interested in how the AWD system works. Right now I have a Dodge Magnum R/T AWD and it has open diffs which isn't the greatest.

I'm getting price quotes for a new 4dr Impreza Special Edition Automatic (/w sunroof/heated seats) for just under $18,000 with 3.9%/72. Has anyone seen better prices?

There is a significant difference between the two. Simply put, the viscous center diff in the 5 speed will always try to maintain a 50/50 split between the front and rear wheels. The automatic will tend to keep more power up front, gradually locking up the differential when the front wheels are slipping. I don't have all the words to describe this in detail right now, as it's been a long time since my training on these systems from Subaru. The 5 speed is definitely a better system though, so I would get that if circumstances allow.

Thanks. I figured the manual had the better system. I am going to test drive one and see what they can do on my Magnum. I'm not sure I'm ready to go from a 340hp tank to a 170hp economy car. We shall see. The Magnum is just at 60k miles and it's starting to rattle and has some suspension issues (most of it my fault from missing a ramp during an oil change, doh!).

I had a 5sp Forrester (which i wanted a manual for the same reason), and now have an Auto OBS.

The OBS drove like a dream in the snow and ice and I don't notice a traction difference between the 2.

One thing to note, I noticed you are in CO. The 4eat with 170hp might struggle in some mountain climbs. The 5MT is better geared and is sufficient, at least up I-70. You might want to test out both drivetrains for your driving roads.

Also - I believe that all current Subies, except maybe the STIs and the Spec B Legacies have open diffs. I think that the Vehicle Dynamics Control (VDC) and traction control are supposed to take care of all that now so you're not supposed to need them.

I've owned an 06 Forester, 4eat, and currently an 08 Impreza, 5mt.

Both are great in the snow.

Automatic trans is nice for just point-and-shoot in the snow, and the car does its thing.

Manual trans is better in my opinion, because you're controlling everything. Easier and more intuitive to get into neutral to cut power, easier to modulate power to start from an icy intersection.

I have seen a video produced by Subaru which shows a Legacy (I believe an automatic) climbing up a set of ramps with only one powered wheel. The other three were on rollers and had no traction. If you're using winter tires like I do on my Impreza, you'll have no trouble unless things get really deep. I did hang up my Forester suddenly in very deep snow once!

For me, mileage is nearly identical, but I drive the Impreza harder than I used to drive the Forester.

Hope this helps.

FWIW we've currently got two 5-speed 2.5 motor Scoobies currently (one Baja one 2010 2.5i Imp).

I really prefer the amount of control the 5-speed gives me.

But that said I've spent significant time behind the wheel of a 2.5 Forester (older one 98) with an auto and it was always FINE in foul weather. Had to take my newborn daughter (3 days old) back to the doctors for a follow-up in a blizzard the year she was born (ya know first time parent, nervous and all that) watched a couple of accidents occur on the way as cars slid into each other, or curbs, or off the road, but the Forrester with Blizzaks was COMPLETELY SOLID, like a frickin' tank - no worries.

So I'd say test drive both if possible, but go with what you want. Both should probably be fine.

And yes, I suspect a 5-speed would be a little more fun to drive especially coming off so much hp, but NEITHER is really gonna compare to that hp.

I bought the 5MT for my '09 Impreza 2.0L (Australia) as the 147hp 2.0L engine we get in our Imprezas really struggles with the 4AT. The official fuel consumption figures are actually better for the auto, which is attributed to it running in FWD most of the time rather than the continuous 50/50 split in the manual model.

When doing some research I found many in the Outback/Forester forums prefer the auto gearbox as when off-roading it is easier to crawl along. I have done some light off-roading in my Impreza (fire trails etc) which can lead to a bit of a smelly clutch if you have to ride it a bit. It is a shame the manual subarus don't still come with a dual range gearbox like the previous generation did in Australia!

From what I gather there shouldn't be a huge issue with either manual or auto for snow/bad weather, however my personal preference will always be for the extra control you get in a manual.

I vote 5-speed, but I suspect that you will be happy with either system.

I've driven a Subaru 5MT in New England winters for 14 years now and I haven't gotten stuck yet (well, once during a winter TSD rally, but I was being stupid and slid into a snowbank). If you've driven AWD on ice already, then you know that it's not a silver bullet. Ice is still ice and you still have to drive smart. No AWD system will overcome stupid driving, no matter how good it is.
