Replying to: dfrancia (Mar 06, 2006 2:28 pm) While I haven't driven them all in snow I think that I have driven or ridden in enough of them to say that pretty much any AWD vehicle will get around pretty good in snow. Proper tires and ground clearance are things to consider. With sport sedans you are trading off ground clearance for handling. Most of the AWD versions of these cars will have slightly higher ground clearance but not as much as your average SUV. Getting around unplowed city streets and unpaved roads with a foot or less of snow should be no problem but venturing into really deep snow is best left for a proper 4WD vehicle/truck.   The other thing to note is what type of tires you will be using. All seasons are adequate for driving year round but if you are looking at several months of heavy winter driving switching to a dedicated set of winter wheels will provide the best traction. Some manufactures such as Audi provide performance versions of their AWD sedans that come equipped from the factory with summer performance tires. These will NOT work in snow and a second set of wheels/tires would be mandatory with such a vehicle. So pay attention to the type of tires that come on the vehicle.   So other than that, it would make sense to concentrate on the other features of the cars to help make your decision, as the AWD systems will perform pretty much on par with one another in the snow. One other thing to keep in mind is that AWD only helps get your moving (which can be a really good thing in slippery conditions), it will have no positive effect on how quickly you can stop This is where having the dedicated winter tires will help.....

Some manufactures such as Audi provide performance versions of their AWD sedans that come equipped from the factory with summer performance tires. These will NOT work in snow and a second set of wheels/tires would be mandatory with such a vehicle.   I've driven my S4 on snowy roads a few times this year. Even with performance tires I had no drama at all. Hills were not a problem either. I was amazed. I don't recommend doing this though unless you're very comfortable driving in the snow.   I've had my '06 S4 for 3 months now and 7K miles later I couldn't be happier. I admit though, I'm kicking around the idea of maybe trading it in on a new RS4 in a few months, but I may hold out for a couple of years and see if the 2008 RS6 gets approved for production. If not, I may have to at least check out the S6. Audi's decision to buy Lamborghini was pure genious. Audi is tapping the Lambo V10's as we speak and I can't wait to get behind the wheel of one. The engine specs on the '08 RS6 are already known- 550bhp V10 according to Motor Trend, but Audi is being real quiet about it and will continue to do so until after the R8 comes out in late 2007.

Replying to: dfrancia (Mar 06, 2006 2:28 pm) You have picked, deliberately?, two cars that approach AWD very differently.   Volvo's version is 95% FWD "at rest" and can move power in reaction to wheel slippage.   Infiniti's version is biased "at rest" to be an RWD car, and the faster it goes, the more RWD-like it becomes. It, too, reacts to wheel slippage and shifts power where it is needed.   Most of the primary and secondary roads eventually are plowed to a reasonable (whatever that means) depth after a snow event. Having said that, during the snow event or during the plowing, the depth of the snow may be greater than a normal ground clearance sedan can straddle, so to speak. Even with pure winter tires, even with studded tires if the depth exceeds the ground clearance, no AWD system is of much use.   I, too, have done things I do not suggest others do -- I kept 4 UHP Z rated summer only tires on a 2003 Audi allroad through the winter here in SW Ohio (which normally is very "moderate" insofar as snow accumulation is concerned.) In one year, however, we did have a bad winter season (for a couple of days) and although I was never stranded, the tires were less than desirable.   The main advantage of UHP all season tires is their resistance to cold temps, not their superior snow traction.   With the AWD systems, however, UHP All Seasons, even here would rarely be inadequate.   With either of the cars you have chosen you will find, broadly speaking, superior winter capabilities.   I would choose the car, however, on the other characteristics, capabilities and content given your two choices. If your only concern is snow traction, to underscore the point, flip a coin; and, based on your location, consider all season or two sets of wheels and tires.   The Volvo has ONE key advantage over the Infiniti -- and that is the Volvo S40 w/AWD (and a nifty turbo 5) can be had with a sport suspension AND AND AND a manual transmission. For me, the Volvo should only be acquired with the stick shift. Given your two choices if you must have the auto trans, go with the Infiniti for many reasons you will be able to glean here with some research on edmunds.   Drive it like you live.

Replying to: markcincinnati (Feb 25, 2006 6:06 pm) Well, that's a very interesting theory( AWD saving fuel ) but it seems highly specious. Every car i know of that's offered in FWD/RWD and also in AWD gets worse fuel economy in AWD. This includes audi torsen systems. The a4 front trac gets 23/34 and quattro gets 22/31, both 2.0T and 6-speed manual.   This is also borne out anecdotealy by acquaintances who have a particular car in both 2 and 4 wheel drive. The 4 wheel drive car always gets a few mpg less with the same driver/driving patterns.   I'm not saying it doesn't exist, but i can't think of one car that gets better MPG with an AWD drivetrain when it's also available with the same engine/tranny in 2wd.

You might say it has too much power. I'd get a winter beater too, if I had one.   -juice

Replying to: dhanley (Mar 08, 2006 5:14 pm) It has been so long since I had a 2WD car I can't recall if I, personally, would ever claim that an AWD car that one can actually purchase when compared with it's fraternal twin 2WD version saves fuel.   The point of my summary of someone else's findings was to present some findings that while perhaps specious may actually be factually based rather than "made up."   "This means that given an “efficient” transmission, it is revealed that an AWD drive-line, in addition to all its other [performance] advantages, can save fuel.    Moreover, this fuel saving advantage actually increases with the power transmitted."     There are data that support the preceding. The info to most of us would be darn near arcane. And, despite its apparent veracity, I am not in a position to even be interested in fully attempting a full-blown "Myth-busters" on it.   A college professor I had, as if that makes much difference these days, said "you need to make certain what you are reading (and writing) has the requisite verisimilitude" for you and from you.   I was probably 19 and had little idea what verisimilitude meant -- so, being the dutiful and well-trained son of a librarian, I looked the word up and I can conclude that the stuff written (and summarized by yours truly) seems to represent and contain the "requisite verisimilitude."   I can imagine many reasons why my production Audi A6 quattro gets a mile or two lower mileage than an otherwise identical 2WD version would get. This does not mean, however, that I think Piech's (or whoever's) "discovery" of the potential for improved economy is bogus.   You, after all, may be right -- but just because something seems to be counter-intuitive, doesn't mean that it is inaccurate.   I am not suggesting a lengthy Thesis Defense is needed. If you find it is bogus, and want to dispute it, that is OK with me.   At this point, even if the study were false, I find many more compelling reasons for the widespread adoption of AWD than reasons to the contrary.     Replies to this message: dhanley (Apr 04, 2006 11:35 am) tradscott (Apr 18, 2006 12:04 pm)

I'll bite.   Infiniti is supposed to debut a new G35 at NY. I wonder if the AWD model will now come with a manual trans?   The S4 convertible and the Concept X (EVO) will be there too.   -juice Replies to this message: esf (Apr 01, 2006 2:54 pm)
