In the hybrid article in the May issue of Motor Trend, they quote: "expect low seven second times to 60 MPG" with the AWD versions, which have an additional electric motor for the rear wheels. And over 600 miles cruising range. |

"expect low seven second times to 60 MPG"  As for the Civic HX, if a compact coupe meets your needs, you can't do much better than a Civic HX. But the Prius is quite a bit roomier and has a lot more versatility than the Civic coupe. It would be more fair to compare the HX coupe to the HCH, in which case I agree it's hard to justify the extra expense of the HCH. FWIW, I've seen real-world fuel economy reports from Prius owners in the upper 40s to low 50s. |

| Could be real. Toyota keeps claiming "sub 8", but is hedging based on the info I can find. Low 7's is not unreasonable. | |
| If a Prius struggles to reach 60 MPG, I doubt a Lexus RX400h could reach it. | |

That should have read MPH, as in low 7's 0-60. Sorry for the confusion. MPG should be low 30's. |

You assumed that ICE maximum 76hp and electric motor maximum 67hp meets at the same time to get 143hp. MG1 RPM behaves as a CVT between ICE:MG2 RPM ratio to merge the two max hp closer together. I do not believe they actually meet though. There will be a loss during conversion but the torque gained from the conversion during low speed will offset that. By looking at the results, the conversion is beneficial because Prius weights 2,900 lbs and it gets extremely high mpg in the city. "Anyway, the 67 hp of MG2 (50kw) can not possibly be supplied by the MG1 ( 10kw or 13.4 hp)primarily. The bulk of the MG2 power input has to come from the Prius battery." You are right but only in high demand situations. During regular driving, as John stated, the battery gets discharged rarely. I estimate that 04 Prius can do 0-60 acceleration 10 times in a row in order for the battery to run low. Realistically, how often do you need to drive like that? Regarding about Prius track running out of battery.... Who knows, maybe performance HSD needs to have more powerful MG1. The work that TRD put in will definitely go into the next HSD Sports car.

Hi Usbseawolf2000: ___From the C&D article, they were speaking of 10.2 seconds on a full SOC and a tad under 15 seconds with 0 SOC. I don’t know exactly how they measured the Prius’ battery pack assistance or SOC but I know the 01-03 Prius BCM attempted to take the Ni-MH to ~ 56% actual capacity. If the same is true of the 04 for batter longevity, the 04 Prius’ 9.8 - 11.2 seconds to 60 is at the best end of the scale. If the pack is heading towards a similar charge of ~ 56%, 12 + seconds to 60 is more then likely the result over time. We will need to see the lab results in a few months to make sure but 0 - 60 times are already pretty low on the scale at 100% SOC and it can only go from bad to worse. ___Good Luck ___Wayne R.
