Replying to: toyolla2 (Oct 31, 2007 6:57 pm) The bottom end torque could be limited just as easily as top speed, not that TC wouldn't already, but only after the "fact". Perhaps a "snow" mode..?? |

That's 90 miles per Imperial gallon, somewhat better than 2004-2008. The batteries will remain Lead/Acid not Li-on as originally planned. |

Replying to: stevegold (Nov 09, 2007 5:42 am) This is set to be powered by a 1.6-litre turbo engine, mated to a more efficient hybrid system. Previously, Toyota has hinted it would use lithium-ion batteries to create a vehicle capable of returning up to 100mpg. However, technical challenges in the development of the new cells has forced bosses to abandon this plan, and instead it will use less advanced lead acid cells.

Replying to: gagrice (Nov 09, 2007 7:02 am) NOT...!! There is just barely enough HEAT level left in the exhaust of an atkinson engine to fire off the catalyst to operating temperature. Certainly NOT enough to "power" a turbo. On the other hand a fully variable speed/boost Supercharger might be an ideal way to increase the power of a 1.6L engine up to the level "required". Adding another variable frequency inverter to power a 2-3 HP AC motor to drive the SC would be a POC. Even better, driving the SC via a combination of the ICE and an AC motor via a form of the e-CVT would be even better. |

We all know that Toyota, as with other auto companies, is on this track of more power with succeeding models whether the consumer needs it or not. With the Prius the most obvious upgrade is to let the 1NZ-FXE engine run at 6000rpm which should up the power from 76Hp to something around 90Hp with only incremental increases in the electrical equipment. Of course the engine may not be quite so clean at this level but does the DOT testing actually require the engine to touch maximum output over its standard driving cycle, does anybody know ? I have brought this up before that the amount of time that full power is ever used is comparitively small, perhaps the standard should be that when cruising at top speed. But could you even fail a vehicle on its pollution count at 100mph since that condition is beyond posted limits permitted in any state ? T2
