You can't compare a car built in 2000 with one built in 2007. A 2007 Camry gets 24/34 vs 40/38 for the hybrid. Making it 11% savings on the highway and 40% in the city. Assuming you had an even mix of driving you get a 26% average savings.

You know what? If they're saving $$$, GREAT!!! Maybe it will send the message to other businesses that they can take steps to become environmentally responsible without cutting into profits, if not potentially increasing them after the initial investment.

What is not being told here is how much Verizon spent on each vehicle to have it converted. Given how much more hybrid cars cost than non-hybrid cars, it is not reasonable to assume that the cost of converting each vehicle for hybrid use could be that high. For example, compare the cost of a 2007 Honda Civic Hybrid Sedan to a non-hybrid Honda Civic Sedan. The hybrid costs about $7500 more than the non-hybrid (assuming the lowest MSRPs are used).

Another factor is that hybrid cars realize much of their gas savings from the fact that they are small. Compare the 4 cylinder Saturn VUE SUV to its non-hybrid counterpart. The former gets 27-32 MPG and the latter gets 22-27 MPG. That isn't exactly a stellar difference.

I am also assuming that a field truck gets more abuse than a standard car, so there might also be a battery replacement needed (especially since older batteries lose their ability to retain charge). There's another ding in the potential savings.

Quoted from »www.hybridcars.com/faq.html

"How often do hybrid batteries need replacing? Is replacement expensive and disposal an environmental problem?"

Answer:
"The hybrid battery packs are designed to last for the lifetime of the vehicle, somewhere between 150,000 and 200,000 miles, probably a whole lot longer. The warranty covers the batteries for between eight and ten years, depending on the car maker.
