P-AWS vs. SH-AWD

So a salesman from a dealership near me told me that the PAWS system and the SHAWD system are almost identical and that I should consider them the same. Does anyone else think this is completely false and a major red flag and that I'm dealing with someone who doesn't know wtf they're talking about?!?! I mean, there's a major price difference and I thought PAWS only allowed you to steer the rear wheels to turn a bit, where the SHAWD was a more robust system using axles, wheels and steering. Am I wrong?

I think I should take the red flag and go with someone more knowledgeable OR they're all gonna be like that and just get make sure I use my knowledge to my advantage, if possible.

you are correct, the salesman was just lumping terms together to get a sale that day.
instead; he/she should ask if you need AWD, or if you are comfortable with front wheel drive.

Dont go back to that Salesman! as your intuition is correct.

Ask yourself, why would Acura offer both P-AWS and SH-AWD if they were the same thing? Your gut instinct is correct and your salesman is a stupid lying idiot.

P-AWS simply turns the rear wheels slightly to help for tighter turns, it however sends ZERO power to the rear and is 100% FWD. SH-AWD is a full time AWD system that can send as much as 70% of the torque to the rear and of that 70% each individual wheel can get 100% of the power to turns like a kayak does when you move only one oar.

SH-AWD is VERY superior to P-AWS by a long shot. It completely transforms the way the car drives and if you live in a place with a lot of rain, snow, or like to drive your car very sporty, get the SH-AWD and don't look back. Now it won't turn your TLX into a rocketship or a sport car, but it really does transform the way it handles and drives.

SH-AWD is very superior to P-AWS mainly when it comes to traction and torque vectoring.

But, each are intended as different approaches to increase handling capability. To that end, the TLX V6 is better served with SH-AWD than without it particularly as the TLX V6 FWD can struggle in putting power to the pavement.

However, in the absence of SH-AWD, its better to have P-AWS than not have it in terms of handling. (Speaking from experience having come from a 14 Accord Sport to a 16 TLX V6 FWD.)

Don't waste your money on AWD ... you are at Miami!!! You know with your 2014 TL that AWD is NOT a necessity.

I would have taken my car FWD if available for sure. You'd save about 1mpg and that yearly differential oil change.(about $150).

Superior indeed.

The issue I discovered though is that you really need to be spanking the TLX at greater than 7/10ths to really take advantage of torque vectoring. And then you quickly discover that the ZF 9AT/weak brakes/non-grippy OEM tires and soft suspension can't cash the check that the SH-AWD is trying to write.

It's true that the AWD is more useful in a location where you get snow. Of course it's worth mentioning that FWD works well in snow too if you have decent winter tires (engine weight over the drive wheels). It's also true that on dry pavement you do need to be pushing the corners rather hard to feel the advantage of the torque vectoring. Doing so with the crappy stock tires requires a bit of a leap of faith that the system will kick in before things go sideways. However, there is another advantage with the AWD on dry pavement. The AWD car hooks up really well when you punch it from a dead stop. Though the TLX may not be the quickest car around, this ability certainly makes it feels quick at launch time.

This is something discussed quite often in the 1G RDX section. All SH-AWD systems (barring hybrid) work the same. However there are actually 2 programs for SH-AWD. One used on lesser models or possibly lighter models like the 1G RDX and the TL and the other on top end models like the RL and MDX. The SH-AWD in my rdx required me to drive like a bat out of hell to activate however the system in my MDX is active on the mildest of turns. This is very unfortunate because obviously these lighter cars will benefit much more.

Today the dealer gave me an ILX hybrid as a loaner (with shitty shitty OEM, I am guessing all season tires...maybe even summers) and it was the scariest time I have ever driven in my life. It has been extremely icy here lately and I am not kidding you when I tell you the car would not move on some intersections, I gave my self AMPLE (1km distance+) room before cars came and it would not move, I was a sitting duck with cars barrelling towards me on super icy roads...to say I have never been as alert while driving in my life is an understatement of enormous proportions. In hindsight I should have returned to the dealer and told them it was unsafe and unfit to drive in these conditions. It really did risk my life. I was never happier to get back into my own car before, literally night and day difference, did not slip ONCE and I own a 2007 SH-AWD MDX with some all season mud+snow tires. Will NEVER EVER buy a FWD car in my life or drive a RWD one anytime but the summer even with sinters.

It would be worth it for me even if there was no snow in NY. Once I made the switch to READ, AWD could be the only alternative. The torque steer elimination, and added push through the corners were definitely worth the premium to me. If FWD was my only option, then I'd be driving something else with rings or a roundel on it.

I did ditch the tires were horrible, and run Michelin SuperSports for 3 seasons which made a huge difference and take full advantage of the SH-AWD system.

The PAWS system does really work, and you can feel it in the corners, but as was said, it's not a substitute for AWD which gives you added traction, and completely changes the handling dynamics vs a FWD vehicle.

I have no input whatsoever regarding the technical aspects of this thread.

But I sure like the way Fibonacci made the point! "cash the check" indeed

The 2nd and 3rd Gen MDX has the best sh-awd programming. It sends more tq to the rear and either side instead of being more fwd heavy like the sedans. The MDX evens switches up to 70% rwd on steep inclines and you can feel it when it does. I even get tq vectoring taking a right hand turn at a stop sign in the MDX while my RDX will only budge 1-2 bars with tq vectoring when I'm +20 mph over the posted speed limit on a tight curve. The MDX drives like a much smaller vehicle with the more aggressive sh-awd when the road gets twisty. You have to learn how to drive sh-awd a little differently since the tq vectoring only works with engine power.

I will stick with sh-awd when I'm ready for my next Acura a few years down the road.

Exactly! The RL and MDX have something called "hill logic control" where on a steep hill they will send 70% of the power to the rear. The TL and RDX do not have this software (I don't recall if my RDX even sent more power to the rear on an incline unless the front slipped) but if the front wheels were on ice, it would send 70% to the rear and this is yet more proof that not all SH-AWD systems are the same. Similar to how Audi calls all AWD Quattro when there are VERY BIG differences.

I will say during my year with the RDX, I got it to send more than 1-2 bars to either rear wheel maybe twice and I drove that thing WAY harder than my MDX. The MDX in stark contrast will send all the bars to one side if I am making a right or left hand mild turn at an intersection going 20mph or less. I once watched a video of a RDX on TOV and the guy went under it and showed that the left and right axles on the RDX were MUCH MUCH thinner than those on the front axle, this indicates that they are rarely intended to receive the 70%.

This makes sense to me that they would cut costs on the RDX and lesser models a little bit by using less robust SH-AWD components.

The 0 - 60 time is .1 seconds faster on the FWD than the SH-AWD, interesting. Perhaps a the very start the SH-AWD gets off the line faster, but the lighter weight of the FWD makes it slightly quicker to 60?

I wish my dealer would have an SH-AWD TLX as a loaner car. I'd really like to see how it feels compared to my P-AWS TLX.

Strangely, I read today that the P-AWS model actually "feels more like a RWD car than the SH-AWD does", but, I will remain skeptical of that opinion until I can test out SH-AWD for myself.

Where did you read about that characteristic of PAWS?

....and yes. The PAWS 3.5 is quicker than the SH-AWD, particularly 0-100 and 1/4 mile traps. Off the line is really dependent on road conditions and the PAWS driver’s ability to get traction under aggressive throttle application, which is no easy task.

To the OPs question, yes, that salesman is a noob and either ignorant or lying. A ton of good explanations and opinions from forum users about the differences and reasons to choose one over the other. I sought out the TLX specifically because it offered SH-AWD, which differentiates it from many other competent sedans. Snow is the obvious reason to want AWD when living in the Midwest. Sure, AWD acceleration in light to moderate snow is superior FWD, but many drivers forget that all-wheel acceleration does not mean all-wheel stop or all-wheel steering in snow. These are the SUV-driving idiots who end up in ditches. But AWD also adds confidence and security in heavy snow to know you can get to wherever you're going. This last year alone, I saw a dozen FWD sedans hung up in drifts, snow banks or intersections they couldn't get out of, stuck without leaving the pavement. I've been there and it sucks. At least two of my FWD neighbors last winter couldn't get up their inclined driveways without a push. To me, it feels better to have AWD when I don't need it (cruising the expressway in the middle of a nice summer day) than want AWD when I don't have it (during snow/rain storms, quick acceleration up a cloverleaf onramp, or a spirited drive on a curvy backroad).

F23A4 makes a good point. I've read elsewhere on here that it's hard to plant all the torque that the V6 makes, even on dry pavement. I've never driven a V6 AWS so I can't compare to mine. But I'm confident in my car getting up and going when I want it to and not having to worry about doing huge burnouts in town or around corners. In fact, one of the many things I love about my car - maybe the top of my list - is the feeling when I punch it from a rolling (5-10mph) stop and it goes. Fast. The ZF9 picks the right gear. No burnout. SHAWD display shows the back wheels maxed out. The V6 pushes you into the back of your seat. The power band feels like it's the entire tachometer range. The throaty exhaust sounds amazing. It feels like I get to 60 in like 3 seconds and I realize I'm 15mph over the speed limit. Guaranteed smile on my face every single time.

If you live in Miami, especially during the winter, you probably don't "need" SH-AWD -- unless you want V6 power. From what I have heard, the V6 FWD is the worst of the three models, neither light and agile like the 2.4 nor solid and planted like the SH-AWD.

The V6 PAWS really only trumps the other two configurations in the area of midrange acceleration and maybe top end, ideally on a dry smooth surface.
