I think that what cdptrap is referring to is that at peak acceleration in a hybrid, 100% of the ICE output is going into moving the vehicle PLUS the batteries are being depleted as the electric motor has kicked in. If you KEEP your foot in it (not allowing some of the engine output to go back into recharging the batteries), then the batteries can be depleted over time.
I would imagine this event to be relatively rare due to the overall capacity of the batteries and the fact that we rarely drive at WOT for extended periods of time (although the issue was a concern for C&D when they were attempting to set a speed record for Hybrids at Bonneville using a Prius).

Dewey said :
"Correct but what do I mean by performance?
Low level of body roll
How it Corners
A musical growl with acceleration(like a BMW growl) "
You have just descitbed a GO-KART!
Thee are so many goals for a Hybrid. Most aren't driven towards perfromance, so the Hybrids bigots try to redefine what performance really is
YMMV cruis'n in 6th and manualy happy! ,

"Heavier weight causes more friction for motion! "
You are kind-of sort-of on the right track.
Netwon's Law's of Motion:
Newton's second law of motion explains how an object will change velocity if it is pushed or pulled upon.
Firstly, this law states that if you do place a force on an object, it will accelerate, i.e., change its velocity, and it will change its velocity in the direction of the force.
Secondly, this acceleration is directly proportional to the force. For example, if you are pushing on an object, causing it to accelerate, and then you push, say, three times harder, the acceleration will be three times greater.
Thirdly, this acceleration is inversely proportional to the mass of the object. For example, if you are pushing equally on two objects, and one of the objects has five times more mass than the other, it will accelerate at one fifth the acceleration of the other.
Actually it is the mass rather than friction that couses the acceleration slowness.

Thanks for the clarification:
Now how about I rephrase my prior statement to the following :
It is the added mass of weight from a bulky battery , an additonal electrical motor and hybrid components that will cause a hybrid's acceleration to be slower than an equivalent car that is powered solely by an internal combustion engine. And let us not forget how added mass can negatively affect the handling dynamics of any vehicle.
How's that for a Newtonian interpretation of hybrid performance?

Check this link for more if any of you doubt you can have your cake and eat it too. www.L3research.com and San Diego State University engineers have designed and built a 260Hp Biodiesel Hybrid sports car that not only gives performance, but also runs on a renewable fuel! www.biodiesel.org.

It was suggested to me that it might be a good time to look at this question again, so the discussion has returned.
Now, in 2009, can a hybrid be a performance vehicle?

Absolutely. Just don't expect to sell many. They would have to be luxury vehicles to make a profit. Otherwise, you just end up with the Accord hybrid.
Actually, you might put most hybrids into this category (depending on how loos you want to make the definition of performance).

What about a hybrid that is projected to get 100+mpg highway, 125mph top speed, 0-60 in 8.1sec, the size and handling of a Miata, and requires no plug in. However it will not be cheap.
Is there a market for this type of car? Can this break the idea that performance and hybrids dont mix?
