Anyone have some good links for other DIY Hybrids? Please post them here!

If I want to be able to "cruise" at 55mph+ and have the ability to do that at least some of the time on the motor, instead of the engine, I'll need to know how many horsepower are required to do that.

Can anyone help with some horsepower calculations? For now, let's assume that we want to use either a VW Rabbit Pickup, a Subaru Outback stationwagon, or Chevy S10 pickup truck. How many HP are needed to push those vehicles down the road at 55mph? Then we can find a motor - AC, DC, or brushless DC powerful enough to do that. We also need to figure in the RPM range of the motor for how it would be connected to the vehicle, and the gear ratio required. Does anyone have a link for a good HP calculator?

Once we figure on a motor, a matching controller can be found/bought/built to go with it.
