    hey guys ,
    i really need your help :)
    this my calculations on toyota prius model and when i calculate the IC engine power i found it equal 162.1 kw
    when i open Toyota Prius Specifications i found it equal only 73 kw

    Where are you getting your figures from?
    What exactly is the question?

    the power i get is 162 kw and this is suppose to be 73 kw as toyota engine
    what is wrong with my calculation ?

    Why is it supposed to be as the cars power output?

    ie, How did you come up with that scenario.
    Is it an official Toyota performance scenario, for the Prius?

    What you have shown is that a car that weighs nearly 1.8 tons cannot accelerate up a 1:5 hill at 0.18g at 60mph with the power output of a Prius. Which I would say is probably right.

    Did you make up the scenario?

    Total power available is obtained by adding the power from the engine and the power from the motors.
