I am in the midst of configuring and ordering a 2010 turbo cab. Is PTV worth it? While it sounds like an "advancement" and helps in the handling, I guess I'm unsure of how much it really does help. I don't plan on tracking the car and while I will push it and have fun, not sure I would be pushing it to the "911 limit" where I would need/notice PTV. I haven't had a 911 before so I'm not as in tune with it's handling/understeer, but the car has been a pretty good handling car without this, and can i save the $1,320 on something i may never use/realize? (aside from the cosmetic stuff and creature comforts, i am getting pdk and sport chrono)

 

I think it is skippable...especially on a cab.

 

worth every penny and then some

 

Yes to Porsche vectoring! The 4WD turbo has tendency to neutral/understeer more than its 2WD 911 cousins; consider all the efforts we go through to reduce understeer in this car: stiffen rear anti roll bar, front neg. camber, front toe out, etc. Torque vectoring by measuring yaw and applying brake to inside rear wheel addresses this very issue. I also think it helps to stabilize the rather happy rear end of all 911's as well and would not be surprised to see it in other 911's. (BTW, this is the same technology seen in the fugly -- but fast -- GTR. I personally think torque vectoring, and PDK, are major parts of the secret as to why that car has such fast lap times while being such a pig -- near 3900 lbs.)

Much more than PDK, torque vectoring & dynamic engine mount are the changes that I wish I could have in my 997.1 Turbo the most. I consider these to be "revolutionary" change and think it would be a HUGE mistake not to get either of these 2 options.

All speculating of course as to date there has been no formal back to back comparison. But the downside is IMO little (less than 1% of MSRP, brake wear (don't know)? feels like a robot (don't know)?), and the potential upside so significant, this is a no brainer. And I don't think you have to be on the track to feel the difference either.

 

PVT is a must have as is SC with PADM.

 

why is it a "must have" and "worth every penny"? have you driven the 911 with torque vectoring or other cars that make have it? is the understeer/handling that bad that this will make a noticable difference? i'm not trying to be difficult, just trying to understand the necessity for more computer gadgets. thanks!

 

for what it's worth, just read this in a review:

"We then embarked on a couple dozen laps, always right behind an instructor and always with the Porsche Stability Management system on. I concluded that the new 911 Turbo is undeniably fast on the circuit, with all that acceleration and braking power, but it’s not that agile or playful. At least not with the PSM going, even if this system allows for a little more drifting than it used to. The understeering is actually accentuated on accelerations and the Porsche Vectoring System doesn’t seem to do much in those situations."

What is PADM?

 

Dynamic engine mounts, which first debuted on the 10 GT3. PADM/Porsche Active Dynamic Mounts.

 

I wouldn't neglect it for it's value at $1,320 alone; as well as residual value. It's appears to be the only way to get a LSD, so basically PVT costs an additional $400 or so, as the LSD option was previously priced at $920+/-. It will only make the LSD that much better. This is one of the many reasons why the GTR is so fast around a track.

I woudn't care what some reviewer's subjective opinions were.

I would absolutely spec it, but it's your money. Considering that you can not get a LSD without is even more validation. The next gen 991 Carreras will likely have PVT as well. It is the future and it is not just hype.

 

PTV is a must have for 2010 TT,otherwise you should probably pick up a 09 leftover for a much better price.
Since you cannot really install the PTV as a aftermarket unit on 997.1 tt yet.

It only cost 1320,and it will add to your car's resell value as it is a new feature. LSD is a must have as well,and you don't need to track your car to appreciate its benifit. If i am on the market for a pre-owned tt, i would skip all cars without LSD. It is a cheap option,but enough as a deal breaker wihout it.

 

In addition, the PTV car also has stiffer front and rear anti-sway bar, whereas the non-PTV car only has stiffer front bar. (There is a reason for this, I think, but I won't go into it now to cause further confusion. It has to do with understeer/oversteer.)
What this tells me is that PTV will further tighten the car's feel, which in general is a good thing with the Turbo.

Trice, I am well aware that the final verdict may not be clear, but I am in agreement with others here, this is one option you want to keep. It is so cheap (relatively) to not take a chance. LOL. Seriously, the risk is little and the potential benefit high IMO.

 

Only you can determine your driving objectives. If this cab is simply a cruizing vehicle PDK and Sport Chrono will certainly keep resale in fair shape and manage the city streets . However if the purpose behind the car is to have the best performing machine that this Turbo can be .. then engine mounts and axle lock (comes with PTV) are desireable . The fact that you opt out of a coupe in favor of a cab implies pleasure driving .

The common term is "show Vs go" . Most guys on the forum want their cars to be geared for performance .

As for the review .. the Turbo does get a lot of flack in terms of handling with it's AWD and Turbo engine . The added weight of AWD and lack of throttle control has the guys in Gt3's and 997S cars touting the prowess of their cars on the twisties .

I have both cars . I like BOTH too.
The Turbo's strongest race is the rolling start or the one mile events . It will eat a Gt3 alive in both of those and for this type of thing the biggest deficit is lacking the roof --not the PTV .

It's your car . You are specing it to your taste . If it was me I woild get all the performance options and make the car a coupe . That's why you have to decide for yourself .. because we all have different driving preferences and priorities.
