Volvo AWD and Subaru AWD

Tmuldoon - 22 Nov 2007 15:30 GMT Hello,
Would someone be able to tell me the difference between Volvo AWD and Subaru AWD, and don't be afraid to dumb it down!
I do mostly city driving, but on weekends head out to ski hills. In the summer - out into the mountains where the weather can change quickly.
Volvo is much more expensive. Subaru says they have 'true' AWD.
I checked Youtube and saw some comparison tests - seemed to setup in favour of one car or the other.
Anyone have both cars and noticed the difference?
Thanks for you comments!

I am aware the vehicles in the video wont be the latest incarnation of each company's awd system.

The Volvo in the video ist not awd, the rear wheels don´t move when he tries to free himself when stuck uphill.

It was a Volvo XC70 - it is AWD (part time: normally it is 95% to front wheels and 5 to the back, but it "senses" when to change distribution, up to 50/50 I think). Obviously it doesn't do it very well, or at least *didn't* do it well. What I've heard is that originally the XC70 had Volvo's own center diff. In 2003 they dropped it and started using one from Haldex. So later models shouldn't exhibit this behaviour.
AS - 24 Nov 2007 17:59 GMT The Volvo in the video is awd, but your statement just confirms that the volvol awd system for that car does not work as well as it should.

Seriously, the Subaru has a locking centre diff. I don't believe the Volvo does
Tony Hwang - 24 Nov 2007 18:27 GMT > Hello, > [quoted text clipped - 15 lines] > > Tmuld. Hmmm, I live in Alberta in the Foothills(Calgary). Driving to mountains ski hills is usual week end activity. AWD, 4X4, whatever, without proper winter tires, you're doing a half job. Most ones in the ditch is Jeep with idiotic drivers who think 4X4 is invincible. AWD with all season tire is just as good as 2 wheel drive with GOOD winter tire. Me and wife do not switch tires but for my kids(daughter and son), they both drive Subaru and in winter they switch to Michelin X Ice. We buy tires at Costco.
bigjim@backpacker.com - 24 Nov 2007 21:55 GMT Winter tires are a waste of money. I never had a problem in snow ice with GOOD all seasons.
> > Hello, > [quoted text clipped - 26 lines] > > - Show quoted text - JD - 24 Nov 2007 23:17 GMT It seems to me that you gnerally have no idea wat you are talking about most of the time. An all-season tire loses traction at about -4C where a good snow tire is good at -25C. A good ice radial will give you grip on ice you can barely stand up on.
An all-season is useless in more than 10cm of snow, below about -5C or on ice. Incidently, it is a pretty useless summer tire too.

Me, Live on the coast (Vancouver Island), and while we get a dump or two of snow each winter the biggest driving challenge is the wet roads. The Goodyear Ultra Grip Ice tires I used to run are the worst rain tire I've ever had. While the Goodyear Triple Treads I run now are the best wet tire I've driven and perform very well in the snow, especially the wet slop we get out here.
It's not a one size fits all scenario.

In US driving from deserts to mountains I've found good all seasons to work on ice and snow just fine. The vehicle and driver are more crucial than the tire. So you can waste money if you want but I'm smart enough to see through the hype. You probably think DRL's are good too!

They make you visible and are proven to reduce accidents because of it.
The driver is more crucial than the vehicle or the tire, but an all-season is a compromise. Would I bother with a winter tire somewhere where it never really gets that cold and snows a couple of times per year? No. But to state a winter tire is a waste of money is right up there with your statement that engine knocking is normal.

No one has ever been able to backup the claim that lower octane has caused damage that wasnt warranteed!

[quoted text clipped - 71 lines] > > - Show quoted text - JD - 26 Nov 2007 01:32 GMT They don't need to back up the claim. If it reduces the life of the engine, it costs you money. If you get fuel consumption that is worse than on the recommended, then it costs money. I have never had to change a high-beam bulb on any car that I had DRLs on (and I generally keep them six to seven years). Its all false economy.
The only thing that keeps any driver from disaster is good brakes and good tires. I prefer not to compromise on either. Its false economy; just like getting crappy gas mileage by using lower grade fuel.

Subaru Outback uses low beams for DRL- I had to replace 3 in 4 years. I disabled DRLs and feel so much better.

If the engine is knocking, it is causing damage. And if the timing is retarded (which it will do when knocking) gas mileage is worse; if your mileage drops by 2MPG, its cheaper to use high test.

What works for you in your neck of the woods may not work for the bloke down the road. Different vehicle, road surface, snow/ice thickness, temperature, length of time road is frozen, etc,etc,etc.
You're never gunna win ! :>)

I went once to the north Michigan state. It was -6F (-21C), roads were black but covered with a slippery thin layer of a salt. To my surprise, I was able to carve quite aggressive corners at high speeds on all-season Continentals.
and I am still look for raw data showing exact speeds/surface type (tarmac/deep snow/shallow snow/ice/slush)/tire combinations where the car is loosing control/traction for braking/acceleration/cornering.
are such available?

Most of the stuff around has to do with side-by-side comparison on ice, snow-covered tarmac, and dry cold road. All-seasons don't fair well on any of those.

Yeah, your statement. Do you live in COLD SNOW country? I don't need to argue with you. You already showed your ignorance.

[quoted text clipped - 39 lines] >Do you live in COLD SNOW country? >I don't need to argue with you. You already showed your ignorance. **Well, talking about ignorance, it was bigjim that said Winter tires are a waste of money, not JD. :) That said, the only car I've ever had winter tires on was a rear-wheel-drive '79 Malibu. All my other cars were either FWD or AWD and I've never had a problem driving either type on snow or ice with all seasons.
As for snow country, I've spent all of my driving years in CT, then MI and then back to CT. I spent 11 years in the tropical state of southeastern Michigan (yearly snowfall avg. 41 inches) and have now returned back home to the Berkshire mountains of Connecticut with a yearly snowfall avg. of 75 inches.

[quoted text clipped - 51 lines] > returned back home to the Berkshire mountains of Connecticut with a > yearly snowfall avg. of 75 inches. Hi, Typical winter temp. out here is -30F. Roads are usually black ice. Poorly charged battery has slush inside. That shows how cold it is. Further up North from here, they never shut of engine in winter time.

There is TONS of information around all-seasons and how poor a compromise they are in any weather; tons. If you think otherwise, you are the ignorant one.
