InsideUPS had an article on the new hydraulic hybrid that is going to be road tested in Detoit. Every now and then in the past few years I see UPS brag about how they are at the forefront and deploying new test vehicles to see how they are doing. I've seen the CNG, LNG, fuel cell, electric and now hhybrid cars. What do you think? Have you seen/driven them? Any thoughts on when there might be a general rollout?
