yes your dad is correct. honda came out with the new accord this year as an 08 model. they discontinued the hybrid because of poor sells. honda is instead making a diesel accord but it wont be coming out until next year as an 09 model. so you will have to wait about 1 year for one. however, honda has yet to release mpg estimates, so the whole 65 mpg thing, i dont know where your dad found that number ; )diesel vehicles USUALLY get about 25% better gas mileage than their unleaded gas counterparts. so....being as the accord averages about 25 mpg (in mixed city and hwy driving) I would guess that the diesel will get about 31 mpg (in mixed city and hwy driving).
