1) The replacement rate on hybrid battery packs is *extremely* low, and they're not that expensive any more. *New* Prius batteries cost $2,229 for the first-gen and $2,588 for the second-gen. Used packs can be bought for several hundred dollars.
2) Where are you getting "similar highway ratings"? The Jetta TDIs score just above 40mpg (depends on what year you got).
3) Diesel mpgs != gasoline mpgs. Diesel is a denser fuel, representing more oil per gallon and releasing more CO2 per gallon. The proper comparison is gravimetric, not volumetric.
