i got a 06 m35x with 38kmiles on it 14 speakers.nav.lane departure warning. Dvd and screen in back. and more for 25k after tax which is the best i sawSo awd is very important to me, but some one told me it will be awd up to 25mph, if this is true what would happen i if i was a bit faster and the rear wheel detected a skid would the front wheel start spining

Also i heard with snow mode on it does awd up to 45 mph.. What if i was going 60 on the highway during rain or snow and the car lost slight control can the front wheels move and get equal torque as the rear wheels? Thank you

Here is some lit that I found when I was buying.http://editorial.autos.msn.com...35277

http://www.familycar.com/roadtests/infinitim35x/

the M35X is what Infiniti engineers refer to as ATTESA E-TS - Advanced Total Traction Engineering System for All Electronic Torque Split. The rest of us can simply call it all-wheel drive.

The important thing is that it allows the M35 to perform pretty much the same as a rear-wheel-drive car under most dry-weather conditions, and then automatically switches to four-wheel-drive when the road turns slippery.

I couldn’t begin to explain how it works, but I can explain what it does.

From a stop to 10 mph, power is apportioned 75 percent to the rear wheels and 25 percent up front for maximum traction. At this point, the power flow is directed 100 percent to the rear wheels unless or until rear-wheel slippage is detected. Then, with the assistance of traction control, up to 50 percent of the power will be transferred to the front wheels.

For the record, the AWD system is the same one previously introduced on Infiniti’s G35x entry-level sports/luxury sedan and its FX sport utility vehicles.

Will it really satisfy the enthusiast who lives in a four-season climate? You might be surprised.

The professionals at Road and Track magazine recently timed a rear-wheel-drive G35 against the G35X on a closed course and found that the all-wheel-drive car posted the best times in both dry and wet conditions. There is no reason to believe that results with the M35X would differ.

Snow Mode

For driving or starting the vehicle on snowy roads or slippery areas, turn on the SNOW mode switch and the indicator light on the switch will illuminate. When the SNOW mode is activated, engine output is controlled to avoid wheel spin. The vehicle should be driven with the Vehicle Dynamic Control (VDC) system on for most driving conditions. If the vehicle is stuck in mud or snow, the VDC system reduces the engine output to reduce wheel spin. The engine speed will be reduced even if the accelerator is depressed to the floor. If maximum engine power is needed to free a stuck vehicle, turn the VDC system off.

Here is some more info from infiniti news.

The key to the performance of the new all-wheel drive G35 is its state-of-the-art ATTESA E-TS™ all-wheel drive system, which is arguably one of the most advanced on-pavement all-wheel drive systems in the world.

The ATTESA E-TS, which stands for Advanced Total Traction Engineering System for All Electronic Torque Split, utilizes an electro-magnetic clutch control design (in contrast to typical oil pressure clutch control) to provide quicker response, lighter weight (approximately 22 pounds lighter than a similar oil pressure clutch control design with center differential) and true variable torque distribution, ranging from 50:50 up to 0:100 percent front-to-rear ratio (versus fixed ratio competitive systems).

Some of the G35 system's benefits over front-wheel drive-based AWD systems with traditional center differentials include:

Faster torque distribution control response to changes in road conditionsAbility to adjust torque without the onset of wheel spin allows G35 to uniquely optimize the torque distribution based on driving conditionsBetter base performance due to rear-wheel drive base layout (versus front-wheel drive based AWD layouts)Better standing start performance on snow through use of Snow-Mode switch

Another unique feature of the G35 AWD system design is the addition of a Snow-Mode function, which reduces throttle sensitivity and fixes initial torque distribution at 50:50, helping avoid wheel spin for smooth starts on snowy roads. At speeds above 12 miles per hour, the Snow-Mode function allows the central computer processing system to take over again, continually monitoring traction conditions and changing the torque distribution as needed.

wow.. This helped alot, thanks for the info. This seems better to me then full time awd and such, on the forum people complained about it driving poorly in snow because of the tires, i am yet to find out since i should be getting it this week, it is being serviced. Had new tires when i took a test drive, but the navigation needs the cds, and a few filters is the rest he has to replace. I have a big driveway with a steep hill in the begining so i will report how it does, hopefully they will put some good all season tires on them, i remember they were a good brand since my uncle used them on his mercedes 4 matic E class before

I live in the Seattle area and have a '06 M35X. Over the week leading up to Christmas we got about 2 1/2 feet of snow. I was extremely impressed with the M35X's snow performance. To leave my street, I make a right hand turn and the road immediately goes up hill. As the hill starts right after the turn there's no room to get a running start. What I found to do is after I make the turn, I just pointed the car forward and pushed the gas all the way to the floor and the car did the rest. The engine speed would just set itself at around 2200 rpm and it would just transfer the power from wheel to wheel - it basically walked the wheels to go forward. On most days I had no problem getting out of my neighborhood, while it would have been impossible with a 2 wheel drive (I tried with my Altima). My neighbor even got stuck with his 4wheel drive pick-up, but the M35X didn't. And this was with Goodyear RSA tires which are supposedly bad in snow, I now have ContiExtremeContacts and I'll be interested to see how they do.

I did find two limitations 1) if the snow is much deeper than the undercarriage, then the car tends to high center and loose traction. The one day I couldn't get out was on Christmas when it snowed 8" on about a 16" base and I high centered and just spun my tires. With a little push, I was able to get back in the garage and called it a day. 2) The other problem is icy, hard packed snow on downhills. Uphills with icy hard packed snow the car did just fine, but it was a total loss of control on downhills. Any braking caused the car to slide and steering did nothing. I think chains on the back wheels may help. I ordered chains, but UPS was unable to get down my street until the snow melted away, but I have chains now and will see how they do during the next snow.

I've been back and forth to Rossland, BC in all kinds of snow. My M has yet to get stuck, altho I try to stay out of areas where I might get high centered. Last winter I got high centered and ripped off the plastic skid plate-sounded like the undercarriage fell off! I've got a custom made piece of sheet metal to replace same-w/no similar problems. Just put your foot on the pedal, gently, and be very careful braking (as w/any vehicle on an icy road). She'll eat snow for breakfast!!

Has anyone else noticed that in snow mode, the 35x feels "heavier"? Idling toward a stop sign, for instance, and the car seems to slow to a crawl rather than float along.

That's probably because the front diff is engaged at 50%.
