Is a GT6 "Performance Point" the same as a GT5 PP?

Or has the PP range been effectively re-calibrated in the GT6 implementation?

I guess I'm not sure I should even expect them to be the same, but I'm thinking that there is a difference, and here is why I have this opinion.

In GT5, I was using a Ford GT LM Spec II Test Car set at a power limited PP650 for a lucrative Seasonal on the Nordschleife. A million credits a lap is nice money. Having done many laps in this car, I acquired the "same car" in GT6 and also used the power limiter to get to PP650.

Took it out on the 'Ring and immediately noticed it felt different. No surprise, a change in the physics model would explain that. I also noticed it was slower along the long straight, and my lap times were longer by some seconds.

So I decided to compare the specs on these "identical" cars. In both cases, the only "tuning" I did was to max out the downforce on both (the scales are different, but I guessed that the maximum values would be the same), and I used the power limiter to equalize at PP=650.

I'm surprised to find that the HP (and Torque) values are quite different in these cars. You'd expect me to tell you that the GT6 car has less power, right, since it's slower? In fact it's the other way around.

The GT5 version, at 608 HP is substantially less powerful than the GT6's 731 HP. That's a 20% difference, which is not small.

Many specs are identical. Weight, width, final drive ratio, and many suspension tuning factors are the same. There are small differences in the gear ratios for all 6 gears.

This post is in no way a complaint, I'm just seeking enlightenment. The comparative specs are in the attached PDF file.

Now it's over to you experts!

Excellent observations.

I can't begin to help answer your question, but I think the answer will be "only PD can explain such things"

Thank you very much for the reply. And I'm good with the "only PD" answer.

I was wondering if the tuning community here treat GT6 as a totally new way of calculating PP, with there being no point in comparing cars of a specific PP in both games.

Sounds like I should not bother with comparisons. Thanks again!

It's interesting that, PP for PP, your particular example is slower in gt6.

Alot of the cars, bone stock, are faster around the Nordschleife in gt6.

Or atleast that's what the stock lap time boards suggest.

Maybe compare what the stock PP's are in each game, then compare how much an oil change adds, or exhaust etc.

That's your huckleberry. GT6 doesn't take increasing the downforce into account when calculating PP, whereas GT5 did. Otherwise there isn't much difference between the two systems. If you minimized the downforce on the GT5 car, I wouldn't be surprised if the power numbers between the two were very close indeed.


As to why it is slower in GT6, I dunno.
 
Also, while in general I find the "feel" of GT6 cars to be better for me than the overall GT5 experience, this particular car felt much better in its GT5 guise.

There's a lot of moving parts in this thing!
