M35x Gear Ratios

[khaug]

Hi all.

Can anyone point me to a list of the transmission and final drive gear ratios for my '09 M35x?

Many thanks.

I don't have the 2009 Service Manuals yet, but the older model years are listed in the Service Manuals link in my sig.

Hi all.

Can anyone point me to a list of the transmission and final drive gear ratios for my '09 M35x?

Many thanks.

Use an online calculator, it's easy and fairly accurate. Take your car up to a specified mph in manual mode using 4th gear, say 75mph, and record the exact rpm. Give the transmission time to get into full lockup so that the rpm is a direct reflection of mph. Using 4th gear puts you at a 1:1 transmission ratio to make it easy to determine the rear diff ratio.

Then just record your tire size diameter, probably 26.7" - 26.5" depending on how worn your tread is, and insert these variable into the calc and it should give you an idea of what your rear differential ratio is.

I use this online calc http://www.richmondgear.com/101032.html

If it's like the 06-08 m35x - then it should work out to be close to the 3.69:1 ratio they have

Thanks, Poyzinous, but the Xs still use the five-speed transmission. Do you have the ratios for it?

4th gear would be 1:1 thats all I know

khaug- Welcome to Nico and congrats on the new M it should make a great addition to your impressive garage. I really like the V10 Touareg (although not legal in my state), although I am not admittedly a VW fan, you have to respect the extreme torque that such a large diesel can put out. If only Americans could deal with the new clean diesel technology due to the poor reputation from several decades ago.

I never noticed that the 09 used the RE5R05A, I thought they switched to the RE7 but it makes sense that since this model is do for a complete redesign very shortly that they would finish the model run with the RE5, but why does the M35 rwd have that. That is really interesting I wonder what the logical reasoning for that was.

The VQ35 in the FX uses the RE7 but that model received it's update already. Now I want an 09 M35rwd even more.

Sorry for the thread jacking.

Again, thanks, Poyzinous. That's what I'm looking for.

Steve, I agree the 7-speed would be very desirable. Guesses for grabs why the AWD Ms don't get it while the RWDs do.

The V10 Touareg is all grins! 553 lb/ft @ 1800 RM makes it the best tow vehicle I ever dreamed of. I do performance driving instruction and tow the Porsche in a closed trailer to schools I instruct at.

The Touareg's predecessor was a 4.7 V8 4Runner which could manage only 9-10 mpg when towing and couldn't tow my rig at 65 mph without downshifting to 4th gear. The Touareg does 14-15 mpg and tows in 6th gear, happy as a clam! What a relaxing tow vehicle, and without the cumbersome mass of an F250 diesel truck or the like. Alas, VW dropped the V10 for the '09 MY.

Best regards, guys.

I really wonder what the reasoning for that is although I doubt you will ever find a straight answer.

So can I ask what the motivation to purchase an M35x was? How did your professional driving experience impact your decision to go with an M?

Does your Touareg use Blue-Tec or a similar urea injection system?

Impressive stones to live in Mi and not use a domestic as a tow vehicle. Although a tunes 7.4 liter Ford is an amazing vehicle I like the concept of a smaller platform and more utilitarian focused interior. A V10 diesel... it's interesting they went with a 10cyl instead of the typical diesel using less cylinders and larger displacement combustion chambers. I imagine that a smaller detonation would make acceleration slightly smoother than a conventional hauler with 550+lbs of torque.

Hmm... Quite....Big displacements are all about noise and heaping mounds of rev ready torque. I wish I could admire vw products with a miniscule fraction of what you show steve. you know how I feel about those things.

Steve, I wanted to replace our M-B E320 CDI that was out of warranty and needing WAAAY too many repairs. I test-drove the M350X not really expecting much and was stunned by its Germanic feel. I'm hoping I've got a Germanic car with Japanese reliability.

The Touareg has a particulate filter, but no urea injection. It is a 44-state car, as it couldn't meet California's CARB NOX emission standards or the similar standards of other states such as NY.

The V10 is, indeed, very smooth. Cross my fingers, it has been 100% reliable so far (23K miles, 24 months). Unfortunately it's again time for an oil change, which involves a fair amount of labor and requires12 liters of very special low-ash synthetic oil, which our dealer sells for $14-something per liter. The last time, the bill was $230.

Cheers.

Care to elaborate? For years MB has had a stigma of reliability and I learned this first hand when I worked there for a little while. The older (late 70s and up to mid 80s) MBs were marvels of performance and reliability for the day. I think their quality hasn't decreased but I'm reluctant to say it is on par (longterm own ability), as the upkeep costs far exceed competitors. That is the reason you can buy a 2003 E55AMG for barely 30k now, but many buyers. The insignia will continue to drive sales despite the fact that the new E class coupe has 4 fog lights and is going in the exact opposite direction other manufacturers are going with the overly complex user interface.

It's gaps like this that are allowing Infiniti to take charge. Within the next few years they will have the market cornered on the Performance Luxury segment of the market. From the rumors of the upcoming models they will be a force the Germans are going to have to adapt to. All that without having a flagship, that leaves a fair gap for the Germans (>100k price point) to keep their dominance. If the do decide to come out with the Essence though all bets are off.

Many people say even the best example of Japanese engineering pales in comparison to even the most basic offerings from Stuttgart. The rift runs deep between the two camps or purists. At the end of the day both regions have their pros and cons, I prefer the Japanese for their practical technology, firm yet comfortable and responsive. They tend to feel lighter than they are too, the M35 is a great example of that.

That is pretty interesting technology they went with on that model. Virginia is one of the states that does not allow vehicles like that to be registered here. The SLR McLauren is another model you cannot have here either. I really wonder why they didn't go for a broader market approach to that driveline. I guess after feeling the water they decided it wasn't going to work. At $230 every few thousand miles and most likely more in filters and other general upkeep items, and the mass market of appeal of the Phaeton VWs decision to pull it's nichemarket division.

Nissan recently came out with a recommended (not required) oil for it's VVEL equipped engines. The cost on that averages $11/qt and people will disregard that solely based off price without any regard for its practical implications. Just goes to show the grass isn't quite that different on the other side of the fence.
