A friend of my husband has a Prius and says that the Camry should/will have a speed above which the engine is forced to run by the controller software. On the Prius it's 42 mph. Above that speed you just have a gas engine car and you can drive it any way you want. All the electric only operation will be below that speed.

So, Hybrid Gurus, is this the way it is?

FYI..his Prius is the very first year that came out...
