Huh? The 4.8 PTT was 520 hp and with PDK is probably the fastest 4-seater around. The thing pushed my eyeballs into my brain!

 

It is fast - but not as fast as the RS7 with the 4.0TT. They are pulling 620 hp out of a 4.0 while we get 550 (turbo S) out of a 4.8. The RS7 with a tune and down pipes is a 750hp car, it requires tens of thousands of dollars and extensive work to get that kind of power out of the current panamera so hopefully a change will be made to get the porsche in line (or ahead of) it's cousin

 

There's more to speed than raw horsepower. There's an interesting Motor Trend Head to Head where the compare the RS7 and the Panamera Turbo, and the Panamera Turbo comes out heads and shoulders above the RS7 in cornering. Which is usually how it is with Porsche - 911's regularly stand with cars with more raw power for the same reason.

It's more extreme in the "sports sedan" segment, because Porsche is the only one that seems to have any kind of effort in that direction.

 

I understand that argument and if I was going to track the car I agree with it. But for daily driving, highway cruising the RS7 is more than capable in the handling department. I also feel the interior and build quality is superior in the porsche but for almost $100K more it should be. I'm ready to make a change from my PTTS and the only 2 cars I'm considering are the new Panamera and the RS7. When the new panny is released if it isn't on par with the RS7 that's probably where my money will get spent.

 

Up to you, of course. But I wouldn't assume there's going to be a big gap. I'm not sure they're really all that far apart now - peak torque for both engines is in the 2000-5000 RPM range, and the PTTS supposedly delivers 800 nm when Sport Chrono is engage to increase boost in that range, vs. 700 nm for the RS7. I wanted to find a graph, but I keep getting graphs for 991's in overboost mode when I search.

As for aftermarket modifications, there's an unknown reliability variable you're introducing whenever you increase boost over expected design limits. I'm more aware than most of this because I used to drive a Supra Turbo, and there's a huge tuner crowd that fiddles with that car, sometimes up to over 1200 HP. Most engines aren't as over-engineered as the 2JZ-GTE.

 

I just configured an RS7 and a comparable PTTS (US spec). For starters, the RS7 quotes 605hp and 517 lb-ft (553 overboost) and the PTTS quotes 570hp and 553lb-ft (590 overboost). My take is that the outputs of both of these engines is comparable and both manufactures quote a 3.6 second 0-60 time.

The price of the Audi (how I would configure it) is about $150k and the PTTS is $201k, so the cost difference is 'only $50k'.

Is the Porsche worth $50k more? That's up to the buyer.

 

Folks, it's official... Panamera is moving to the Audi bi-turbo engines...

Get your true Porsche-engineered V8s while you still can, especially the NA V8 in the GTS.

Hmmm - may be semantics, but the C&D article referenced twin turbo. They are basically taking out 100cc per cylinder and increasing output by 6% or so from the current PTT engine.

I wonder if they have accounted for the Turbo S variant and how much power that will deliver. While the RS7 already has a 4.0, I suspect that it is different from what Porsche will be manufacturing (but perhaps not and VAG just playing a shell game).

It will be sad to see these gas guzzlers go - I believe that the same basic architecture launched in the Cayenne many years ago - it has been a great engine (the NA variants are/were terrific).

I wonder what the driving impressions from owners was when the Cayenne GTS went from the NA to the smaller turbo engine.

 

If you go over to the 958 section one guy bought a used GTS and loved it so much he went out and got a 2016 one. He's now selling the 2016 one with the turbo engine, and keeping the NA V8 one that he bought used.



BTW what the **** is up with the wing on the turbo?

 

I certainly miss my 2008 Cayenne S with the NA V8 engine - sweet sounds and the engine had good punch. The Cayenne was over engineered and built like a tank. I do love my PTT and I'm hoping that it will invoke the same feelings that my Cayenne did.

 

My initial guess on engines in this thread seems somewhat confirmed (4.0L V-8, 3.0L V-6), but the power output of the 3.0 V-6, if what the article says is true (S4 engine coming to the Panamera) comes true, is likely more; the S4 engine is 354 HP / 368 lb-ft!

 

I don't want a S4 engine in a Pan, I'd buy an S4...

 

There is truth to this. Even the current base V-6 is a derivative of the 4.8 V-8, so this article may be false. They might end up sharing displacement but that might be all.

I'll take the v8 diesel all day long. I wanted that power plant for years in my cayenne! Why not NA...
