Couldnt let this go unaddressed-- Car and Driver tested the Prius acceleration and found 0 to 60 to be 12.5 seconds. The 1/4 mile and 0 to 90 data are worse still.

I have no idea how the prius got a 0 to 60 rating of 10 seconds initially; it ain't happenin. The HCH II has better accelaration, and particularly between 50-70 MPH- leaves the Prius in the dust, which is exactly what I do driving around and by Prius' here in Houston.

Interior room- actually for the driver the HCH II has as much room as the Prius. MPG- In highway driving the HCH II gets better mileage.
