I spent all morning reading about the different all wheel drive systems each manufacturer offered notably between BMW, Infiniti and Mercedes. All different but still the same. Most people won't care but since I live in the great white north, I'm interested since the white stuff comes a little too often. I had a chance to test drive an Infiniti G35x two days ago and I came out very impressed of Infiniti's awd system. What I loved even more was it's ability to send full power to rear under hard acceleration. I'm not sure if he was right or wrong but the salesman also told me that it reads the ext temp and during summer cruising, the power is always mostly send to the rear. True or false?

P.S I didn't bother including Audi since I supposed they only offer AWD on their cars. We're talking natural-propulsion vehicles that offer AWD.

The X-Drive 40/60 split

The ATTESA E-TS

4Matic


Your opinion?

 

Unless it does torque vectoring its last gen

That said, on more obtainable cars I would much rather have a system with a rear bias.

 

I think your dealer is smoking something...the system does not measure any outside temperatures to determine where to send power.

But also, I think you are mistaken about when power is sent to only to the rear wheels...Infiniti's system sends 100% power to the rear only when steady cruising and under very moderate acceleration. Any other acceleration from moderate to hard will send power to the front wheels.

It is very much rear biased in all conditions, but it is only 100% RWD only when cruising.

 

Just buy something already... it's not like you're gonna have it for longer than 6 months anyways

 

do you have a link to the article?

 

I did buy something, look at the signature!

 

Post some pictures!

 

lol, I think you should also consider the SH-AWD equipped RL (I'm sure you can afford it judging from your signature!). Or if you don't want an Acura, wait until BMW and Audi come out with its own torque-vectoring AWD.

Out of the three though (Attesa, 4-matic, x-drive), I'd go for Attessa, even though it's not the same one as the one used in R34 or R35 GTR, but it is perhaps the best out of those 3.

The S-AWC from Mitsubishi is also extremely good, but I don't think Sports Compact is your cup of tea?

 

Will do post a few of the A8 once the weather permits!

 

Some interior shots! Nothing special like your 335 though but a very comfortable, quiet and fast cruiser!

 

That'll have to do for now Jesal, later I will take some personal ones and not dealer ones later.

 

Nice....too bad they didnt make the red and white combo.

 

Nice A8

X drive isn't a 40/60 permanent split. Its a variable torque split transfer case. It can go from 100% torque to the rear to a 50/50 torque split.

 

Thanks for the info. I didn't know!:wink:

 

The 4matic in the ML63 has percent 40/60 split.

 

ATTESA is interesting...

From a standstill, it always starts at 25/75 Front/Rear under normal conditions then goes to 0/100 in normal cruising.

In Snow Mode it is locked at 50/50 up to 15 miles per hour.

Maximum transfer is 50/50 Front/Rear.
