PiP high rolling resistance vs my gen 2

Hello knowledgable forum members!

I have bought a 2012 PiP a couple months ago. It had about 27500miles on the odo and was in very good shape. It came with 17" Prius wheels but i have replaced them with 15" prius wheels with new Bridgestone Ecopia EP S001 which is their lowest rolling resistance tire available here in Sweden. I have the older EP 150 on my 2008 gen2 which is the older version with slightly higher rolling resistance and this tire comes stock on the PiP here.

The thing is that the PiP glides considerably worse than the G2 and i am curious if any of you have had the same experience?

I will have a wheel alignment done eventually as that is the "only" thing i can think of that might be slightly off with the car. It rides good but perhaps not perfect which i must say that my G2 does that have had a full alignment done with shimming of the rear axle by my very knowledgable friend who works at a Toyota dealership.

The brakes have recently been overhauled by me and my friend to.

The tires have rolled 1000 plus miles could it be they are not broken in yet?

I instantly feel a significant difference when i get in the G2 after having driven the PiP for a while and a good friend with a G2 have verified it to.

The only other thing i can think about are if the secondary planetary gearset in the transmission is causing more losses when gliding but i have been unable to find anything about it.

Would like to hear your thoughts!

Thanks for all feedback!

To clarify, the brakes we cleaned and lubricated as a preemtive mesure but we also noticed that one glide pin on each rear side were rusted stuck so i have got those replaced along with new disks and pads under warranty.
The brakes have no binding.

Close to sidewall on both cars.

I get a little worse fuel economy on the PiP on my 10mile one way commute if i dont charge. Around 50mpg and about 55mpg on the G2. Basically no P&G on this route more than because of elevation changes.

I run Toyota 0w-20 in both cars slightly underfilled.

I feel that pulse and glide dont work very well on the PiP because of the poor glide but it works very well on the G2.

Is there anyone that have similar experience going from G2 to G3/PiP?

 

Yes my expert friend thought it was very strange too but i am pretty certain the history are ok. Both other pins looked like new so there must have been some fluke going on there.

 

To clarify.
Both cars do NOT glide the same in neutral and i am not talking about how the car glides when the trottle is backed off all the way. I am very familiar with driving a prius, i have been driving our G2 for four years and consider myself a hypermiler having learnt alot from this forum and you guys over the years.
I practically always drive to maximize mpg or in my case minimize l/100km.

That beeing said i have a good feeling for these cars by now and what i am after is if anybody here have had a similar feeling in going from a G2-G3/PiP as far as the unassisted/unresisted glide are concerned?
That is do the PiP glide worse than the G2? If so is it because the second planetary gearset in the transmission or does the PiP pure and simple glide as well as the G2?

If it is supposed to glide just as well what else could it be? Wheel alignment? Bad transmission oil? Mecanical issue?

Driving a Prius is what i consider having a really good time but it is not so much fun when i know how well the G2 does at lower speeds

 

Interesting! Is this well understood how this programming are supposed to work? I definately feel the two cars are alot different to drive and perhaps i have not got the hang of driving the PiP well yet.
