Hmm, still I would take a Prius and the hybrid batteries over the explosive potential and EXTREME cost increases of hydrogen fuel cell or ethanol driven vehicles. Having said that, I would think Prius for city work with occasional highway, while TDI for mostly highway use. One big factor that many here but not many outside understand is that turbo's operate best under certain higher heat conditions and loads than a non turbo, and that "blowing the carbon" (archaic term) is what helps keep them spinning properly. Take note about the use of ultra low sulfer diesel fuel and the requirements of keeping your idle time low to prevent soot build up and the associated troubles with it. (Semi drivers learn this quick as a failure for us can mean a 17,000 repair bill)
