4-wheel drive (passenger cars) - Torsen, Haldex, X-Drive - Which one pleases you best?

Subaru offering beats all of these.

In my opinion Subaru Symmetrical AWD is the best system out there, 40+ years in service and engineered and refined to near perfection and a proven system, they are the original masters for AWD in mainstream passenger cars.

Honda's SH-AWD is the best technically and modern system I have come across, they just havent deployed it in many of their cars yet, but it will start filtering in once costs and fitment becomes suitable.

i have to say after reading this: http://www.pistonheads.com/news/ph-americancars/tesla-model-s-p90d-review/33647 i very much like the sound of just having two seperate engines motors

My 1M Seat Leon Cupra 4 had a Haldex Traction multi-plate clutch (like the Golf IV 4 Motion). Can't remember if it was Gen 1 or Gen 2, but it was brilliant on snow.

My 8P Audi S3 had Quattro Haldex (obviously) and that was also brilliant in the snow and in the wet.

I've run lots of 4wd systems in the past, but the Evo did stand out in snow... particularly in its ability to hold a steady 30 degree angle down a dual carriageway.

This link gives some good info on the different evolutions of the Quattro system. The RS5 has torque vectoring... didn't realise that :- http://www.awdwiki.com/en/quattro+evolutions/

Having driven a few four wheel drive vehicles, my current Nissan Stagea M35 with ATTESA ET-S is the most entertaining for everyday driving. The system on the M35 is setup to deliver 100% RWD unless it slips, so it retains the desirable feel and handling until its nearly too late. The ability to force 50/50 is also great for snow/gravel/mud.

Never seen a 4wd Leon. Are you in Europe or outside UK?

And the A3 are all Haldex AFAIK.

The new NSX has a motor on each front wheel aswell.

A3's are Haldex - but any 4WD Audi's are branded as "quattro" (lower-case Q), regardless of technology employed.

Yep. I know that. Just mjt stated (upper case) quattro rather than Haldex. I am aware of the differences having owned both.

I think Audi Quattro (Torsen) has one disadvantage: it tends to suffer from front wheel slippage under heavy acceleration when driving on the icy roads.

Porsche C4S... only 4WD car I've driven that I actually liked... but that's because it felt more rear-driven to me than the C2S that wanted to understeer everywhere.

The comparison of the two most likely helped by the C2S having an open diff, which will have pushed forward more than wanting to kick the rear out like one with an LSD would have.



As for your list, I'd always prefer the ones that are prioritised toward the rear and only connect the front when needed... like a wet clutch to the front.
