        Take a look at the Dodge Intrepid ESX proto HEV. They have 250HP
Zytec (Zytek?) electric motors mounted where the brakes would be.

        Try Capstone Corporation's website at
<http://www.ring.com/capstone>, they build a small, fuel effecient
turbogenerator that produces 24kW, and weighs 165 lbs.

        I'm not sure how to work the kW to acceleration thing. My general
idea on this subject is this, take the Zytec motors, mounted in a small car,
with a generator (Capstone's seems ideally suited). Sure, maybe the 250HP
Zytec's are a bit much, but why not 4 smaller motors at each wheel? Say, 75
or 100HP each? 
        If I build an HEV, then it's going to have to perform as well, or
better than, the car with it's IC powertrain.
