the snow and AWD do not mix unless you have traction control (This is true).

Uhh..., regardless of traction control, AWD will be better in snow than FWD or RWD.  In fact, just comparing generic drive systems (not any specific vehicle) and with no fancy electronic anything (so just the drive system, no TCS, etc.) on snow, AWD will be the best, followed by RWD, and FWD is the worst.

Let me explain how that works, it is usually 60/40 there is either an auto clutch to make it 50/50 or in the STI it is a knob. So if the front tires are spinning and the back ones have grip, for example going around a corner when coming out of my neighborhood... you now have a rear wheel car, which is nice to have in the summer but on hell of a bitch to handle on the road when it is slippery.

If considering a standard subaru, you have a limited-slip center diff (front/rear power split) and just regular open diff's at the front and rear.  So - in a situation where you apply too much power for the road condition, power will be split front/rear as evenly as possible (regardless of 40/60 or 50/50 split), and 1 front tire will spin, and 1 rear tire will spin.  In a corner weight would shift to the outside, so the inside tires would be the ones spinning.

In the STI it's limited-slip diffs front, center, and rear.  If you apply too much power, all 4 wheels will spin.

And of course a traction-control-system will totally change what I just said, as it will apply individual brake power to any spinning wheels.  That will cause the diff to send more power to wheels with traction - if they spin too TCS may intervene and reduce your throttle input.

I just looked at the Audi A3 it would be probably 5K more then my Subaru, which was 29,500K but it is also a solid car. So I think after the winter is over, I might convince my wife that the A3 is a much better car or just sell the Impreza... anyone want to buy an 07 Impreza Special Edition, slightly used (8 months or so)... only 18,000 km :D

Unfortunately the A3 is only available in AWD if you get the 3.2L engine - aka the S3, which is priced in the 55K range.  Also, with the bigger engine and AWD it is only available in automatic transmission..


Ok, ok let me back up the AWD is very nice to have and it seems to work very well when I am on the highway / freeway or when I am taking larger turns but sometimes during the stop and go traffic when I turn left or right I seem to loose control of the back end. I was playing with it last night it takes a bit of getting use to but now I can control it and compensate for it.

Ok here is the real reason not to get a Subaru, I had a tire puncture about 4 months after I got my car, I didn't want to buy 4 new tires so I called up Subaru to see what they could do. I was told the tire would cost 475 dollars, I said pardon... I only want one tire, and no rim. Yep it will be 475 for that tire and it won't be in for 4 weeks... Now I held my temper and said you mean you don't keep any in stock? Nope we are a small shop she replied and said that they don't keep a lot of parts in stock. I asked how long she would guess it would take for a part for the engine would take? About the same time frame. Now I called around and found really there was no price difference for those tires anywhere and they seem to be very expensive. I am just wondering how much the STi tires would cost? Oh and how I got the puncture, damn construction by my house at least I got the construction company to pay for it. Total price $509.00 to mount and balance the tire.

So you would take a RWD car over a FWD car in the winter?  I always thought it was better to pull the car then push the car? Well I guess I have learnt something. :D

I'm trying to imagine what you're describing here.  Do you mean that you were traveling in a straight line, then tried to turn but couldn't because your fronts lost traction (aka your car understeered)?  Or do you mean that you were stopped at a corner, then hit the gas and tried to turn but the fronts lost traction and the rear swung out?

The second one I stop to turn on to another road and the back-end will swing out from the front tires. The only saving grace is that the front end will pull the back end into place. [..] I normally try not to drive too fast but it seems either the tires or the awd cause the car to act out of character.

Sounds like too-liberal an application of the go pedal...  The front tires are probably spinning as well but you can't tell because you're focusing on the rear swinging out.  If you were driving a FWD or RWD car through that same corner, would you be givin' it as much gas, or would you have to keep off the gas more to keep the car from swinging out?  The answer to that question will indicate whether you're just driving it harder because you think it should have better traction...  And I can tell you I drive my Suburban more aggressively in the snow than I do my FWD light-weight Colt because, well, the Suburban has better traction.

Are the tires summer or all-season tires?  True winter tires that retain their pliability and elasticity might give you the grip you're expecting.  (checks subaru.ca) Yeah, they're low-profile all-seasons...  If you're looking for some, I suggest you mount them on winter rims, go an inch smaller on the rim, and at least 10mm less wide for the tire.  So, your WRX has 215/45R17 regular, so I suggest 205/55R16 winter tires.  The Michelin X-Ice on canadiantire.ca (I'm only referencing CanTire because they actually publish prices on their site) are listed at $192.74.  Throw in a steel rim and hubcap and tax and installation, you're probably looking at a $280-$300 price tag per tire.  For some people that's too much, for others it's a worthwhile investment in winter traction.

I'm surprised they didn't just plug the hole for you for a couple tenners.  Was it a huge puncture?  $475 for a specific tire of a specific make and model is believable (I don't even know what tire store would carry Potenzas)...  But you could've bought a couple performance tires of a different brand for less.  Still, I'm really surprised that they couldn't just plug the puncture.  As for time frame for the parts, well, there aren't a lot of WRXs on the road in Edmonton.  If you had a regular Legacy with the other motor the parts would more likely be in stock, because there's a larger customer base to sell them to.  Still, when parts are made in Japan or Europe rather than here (I'm looking at you, Mitsubishi and BMW!), it can take forever and they cost too much.  He'll have that same problem whether he buys the Sube or the Audi.

So you would take a RWD car over a FWD car in the winter?  I always thought it was better to pull the car then push the car? Well I guess I have learnt something. :D

I would have to try each car before picking one over the other.  Some FWD cars slide like crazy because of poor weight balance.  Some RWD cars have good snow traction because of proper weight balance.  The size and type of the tire matters quite a bit, too.  And then you throw in letter systems (ABS, TCS, ESP, ABD, etc), and it's all up in the air.  In emergency procedures I'm more comfortable driving a RWD than a FWD vehicle because the response to throttle and brake input seems more natural to me.  Although I've found the Suburban's AWD response the *most* natural.

Puncture was a side wall rip...  >:(

The tires are all seasons I believe, I think I will look at getting some winter tires next year, this year was a trial year since I have never had a car with winter tires. Also I am driving about 50% more now so I guess it would be a good idea to look at winter tires and summer tires.

Some background on my last vehicle, it was a 2002 Grand Am Manual and FWD now I have a 2007 Impreza so I guess I have to get used to well an automatic transmission (That was my wife's idea)  and AWD. :D

I was playing with it last night it takes a bit of getting use to but now I can control it and compensate for it.

First off, especially on snow/ice, you have to be prepared for at least a little bit of sliding around - but that doesn't mean loss of control.  When you know what you're doing you can use the throttle to help get the car around the corner, and I don't just mean stunting.  If you want some time, I'll take you out somewhere to find a nice big empty parking lot/field that hasn't had its snow cleared, and do a little training on car control in slippery conditions.  Best way to learn to control a car thats sliding, is to spend lots of time in cars that are sliding.

As to the reason behind why the back-end is sliding out on you, I am going to guess that the TCS is the only thing keeping the front wheels from also spinning and sliding, and you need to wait a little longer in the corner before getting back on the throttle.  The WRX I test drove late last week acted in a way consistent with that - with the TCS on if you were heavy on the gas you could still slide the ass-end around, though the front wheels stayed planted.  Of course, with the TCS off the WRX was very happy doing nice very controllable 4-wheel drifts.

1. Why didn't you repair the existing tire instead of replacing it?

2. I'd never pay that much for a tire - I'd just go down to tire village or a similar place, and order 1 tire of the same brand/model/size that Subaru uses.  For comparison - I had performance summer tires on the RSX, almost identical tires to the factory STI tires except in a different size, and the set of 4, mounted and balanced, was about $1100.  And I got a screw in one of them a few years back - had it repaired at canadian tire, took 1/2 an hour and didn't cost much.  Now the STI would come with 18" rims, so that'll bump tire prices for it up to the about $300 mark prolly - but thats no different than any other car with 18" rims.

Quote from: Adams on December 06, 2007, 08:30:45 AMSo you would take a RWD car over a FWD car in the winter?  I always thought it was better to pull the car then push the car? Well I guess I have learnt something. :D

The only advantage FWD has is starting from a slippery intersection, most of the vehicles weight is on the front wheels which gives you maximum traction there (especially if the vehicle is naturally front-heavy eg. a truck).  Acceleration in non-slippery conditions FWD loses traction because weight shifts to the rear.  Torque steer is another issue that virtually all FWD's have - the torque from the engine turning the front tires ends up partially transfering through the steering, and the car pulls left/right when you get on the gas.  In the corners, FWD understeers, while RWD oversteers - I'll take oversteer anyday, where the front-wheels still maintain traction and with a little counter-steering you can keep the car on the intended path.  The moment you lose traction in a FWD, you lose steering as well.

Or look at it from a slightly different point of view.  Your car only has 4 small patches where rubber meets pavement - and all engine power, steering input, braking, etc. all has to get by with only the friction from those 4 small contact-patches.  Don't you think it makes more sense to use the front 2 for steering and the back 2 for acceleration, instead of the front 2 for everything, and the back 2 just hold the ass of the car off the ground.

And finally..., if FWD is so good, why is it that none of the high-end cars use it.  Porsche doesn't make a FWD vehicle.  BMW doesn't make a FWD vehicle.  The only FWD mercedes is the new B-class (their cheapest car).  Infinity I don't think makes a FWD vehicle.

Thorin

Porsche, no.  BMW owns and directs the design of Mini, a FWD small car.  Mercedes has a stable of models sold in Europe but not North America that are FWD (and diesel).  Infiniti used to have the G20, a FWD 4-cylinder.  Acura and Lexus (direct competitors to Infiniti) are all about FWD in their cars.

Other high-end car manufacturers?  Cadillac used to be FWD only but is now mixed.  Volvo has FWD nowadays.  Rover doesn't sell any cars in Canada, but they have FWD cars in England.  Jaguar sells both FWD and RWD.  I guess the question here, though, is what is the cut-off to be considered "high-end"?  Price?  Drive configuration?  Do we look at manufacturer or at each individual model (Porsche has $60k cars, Chevrolet has $110k cars)?

I will take a well-designed and -balanced vehicle over a poorly-designed and -balanced vehicle any day.  For instance, a Buick Century (FWD) drives much nicer in the snow than a Ford F-150 (RWD), and an Infiniti G35 sedan (RWD) drives much nicer in the snow than a Ford Focus (FWD).

And a different power output, different initial throttle response, different weight balance, different wheelbase, different tire size, and possibly traction control (don't know if your Grand Am had traction control - it was dependent on what model and trim level you had - but your WRX should have it).

So back to the original topic - Cova, have we poked enough holes in your two picks yet? :D

Sorry for topic hogging... I am guessing you are heavily choosing the Impreza... what dealership you going to? I dealt with Renzo @ the South side Rally Dealership. Nice guy, good knowledge let both me and my wife do some donuts in a parking lot to see how the AWD worked.

I suppose "high-end" was the wrong term to use, as there are a few examples of very nice, very expensive FWD cars.  The RWD split is aligned more with cars designed for people who enjoy driving (which is typically higher-end stuff, but not all), and who would likely have the experience to know how to handle a RWD properly.  Where FWD vehicles are marketed more towards soccer-mom's who just want to move the kids from point A to B.

I'd still take the F-150 over the Century.  A few sand bags in the back and decent tires and you'll be fine.  Or for a more interesting ride, make sure the weight you add is unsecure and slides around easy :)

1. I don't mind the topic drifting around.   We're still discussing cars, we're keeping it civilized, and

2. I've pretty much decided on the 2008 STi.  Through much discussion (both here and elsewhere) I've come to the decision that I'd rather put the $ into engine/drivetrain/etc. instead of interior luxury - the STi meets my luxury needs (heated power everything, 7" touch-screen navigation, automatic climate control, etc.)

So with that said - here's another pic of the STi, and feel free to take this thread off onto other topics, as long as it remains car/driving related.

So far I've also been dealing with Renzo @ south-side rally.  Ironic that you had the same salesman, and double-ironic that Renzo happens to be an old friend of mine.  Hadn't seen him in probably close to 10 years - walked into the dealership last week when I test-drove the WRX, and it was one of those "Hey - you look familiar, I know you" moments.  He took me and the WRX out to a empty field full of now - doesn't get much slipperier than snow on grass - and we played for a bit, checking the AWD with and without TCS, testing ABS, etc.

And feel free to "topic-hog" - if it was bothering me I wouldn't have written all those giant responses.

Nope.  I much prefer new over used - especially considering to import a Skyline it'd have to be 15+ years old.  It would also not have some of the interior-luxury that I'm looking for (eg. heated seats mandatory), and being a sedan-style with a trunk also doesn't meet my storage requirements (must be able to haul my mountain-bike, or the entire set of gear I take to LANs - includes office chair).  I'm sure it'd be a great car to drive - it's just not the one for me.

I don't think I could go back to a car that doesn't have heated seats.

Thorin

I was driving a car with heated seats long before the idea took hold in North America.  Back in 1989 I was tooling around in a Volvo 240 station wagon imported (via the Volvo Diplomat import service) from Sweden (thank you mommy and daddy for providing a brick for me to learn on).  Since then I've had cars with and without heated seats, and currently have two vehicles - one with heated seats, the other without.

Although sitting down on a warm seat is nice, there are some things to consider
- Overheating the lower back will cause it to tire more quickly; to test this, try setting the heat on high for a five or six hour drive and notice how tired your back feels when you get out
- Overheating the buttocks and thighs will cause less warm blood to go to your calves and feet; to test this, get in your car when it's really cold out and set the heat on high - notice after fifteen minutes that your feet feel like ice cubes!

The only time I miss the heated seats while driving my non-heated-seat Colt is on those first ten minutes when the car is still warming up.  After that, the body heat is retained and reflected by the seat enough for me to stay warm.  The heated seats feel nice 'n all, but I can imagine driving a car without them no problemo.

Now, hot air out of the ventilation system?  *That* I couldn't imagine driving without!

If you have a leather interior, heated seats are a GREAT thing in the winter.. As for the over heating I have never used them for more than the initial warm up.. I don't like the extra warmth all the time.
