Did we ever find out if they did away with the fuel bladder? I believe I heard yes, they did ... but was unsure.

Hi Danny,
Thank you for the information.

I believe Toyota revised the numbers, 51/48/50.

I believe the rear suspension does not come with stabilizer bar, same as Auris.

At Detroit, we saw it was Bridgestone ECOPIA EP20 which is the OE version of ECOPIA EP100 summer tire.

Can anyone solve the puzzle?

Ken@Japan

Yes, poly resin tank now. No bladder.

Also - This info seems to be a reprint of the preliminary info provided by Prius Team in another thread. People spotted several typos and errors in that info, so people should review that thread. E.g. - Turning circle numbers are actually radius numbers; and there's one mistaken tire size reference to "185". There were other errors.

The current Prius has one, I would expect the new one to have it, too.

You're correct about the current Prius suspension.
Toyota Prius: Base specifications here
"Rear Suspension: Semi independent, torsion beam with trailing arms, strut-type coil springs, gas damper units and anti-roll bar"

Are you familiar with the 2010 Prius suspension is same as the Auris/Corolla?
Toyota Corolla: Ascent (Hatch) specifications here
"Rear Suspension: Semi-independent trailing torsion beam, coil springs and gas damper units"

FYI,
Following figures are Iconic Prius rear suspension with the stabilizer bar and Auris rear suspension.
I think Auris's one (same as 2010 Prius) is stiffer eliminating to add an independent stabilizer bar.

So, you missed post #3 and #9 of this thread?

Ken@Japan

I believe from memory the rear suspension cross member is an "S" form rather than the iconic "C" form with the sway-bar in the C. I suspect the "S" form of the cross member makes it stiffer so no need for a sway-bar.

OK, I'll probably betray my ignorance here, but isn't the cross member in the 2010 that we've all seen pictures of (forward of the rear beam) considered a stabilizer bar?

here's the picture:

Following picture is shown the Iconic Prius rear suspension torsion beam with the stabilizer bar.

My observation is the 2010 cross member is something like upside-down "U" shape.

I agree.

I believe no need to add a separate bar.
