Conclusions
  • The case for hybrid is stronger for sedans than for SUV
  • The case for hybrids is stronger as fuel cost per gallon increases
  • Bio-Diesel at 80% diesel mix is not going to save money but no maintenance issues
  • Alternative fuels will reduce pollution regardless of the cost scenarios
