I agree with you, more accel power would be great as well as a higher EV mode speed. I find better accel power when I have a full charge. I've been seeing a lot of hype about the A123 systems new LI-ON batteries. Wonder if that would help?
These cars ultimately get all of their power from the gas engine. The system is designed to run the gas engine when it is more efficient than battery only, and acceleration is one of those times. When the battery is near full charge it will allow more battery-only acceleration to drain the battery down to insure it will be able to absorb regenerative braking energy.
Some times, when im on back roads, i will force the EV mode until the battery runs down to empty. On almost flat roadway i can get about 2 miles in ev mode before the engine forces on. I get some of my best mileage this way. What is the top speed for EV mode in your TCH? My top speed is about 41-42 MPH then the gas engine kicks in.
Can you mod the HEV for more / longer EV use?
