Here's an interesting diesel-electric hybrid truck I ran across that Kenworth has been making for a couple of years now, particularly for use in urban areas with a lot of stop and go traffic... the T270 Class 6... with battery system and electric motor included as part of the powertrain, but in a very different configuration from the Leaf.
As I understand it, it's got a conventional diesel engine and transmission which are used at highway speeds, while the electric battery-powered motor kicks in with additional power at speeds under 30 mph. I wonder if that's what the WAVE is up to.
Here is also my thought. If you can double the big rigs MPG - you should be able to double the light truck (3500 series and below as well) In nasty city traffic I get 14.5 - 16, on the highway 18 or so depending on how fast I drive. All time high is 21 where I was limited to 50 mph on a long stretch of highway. I actively watch this kind of stuff as what works in the big rigs eventually filters down to us little guys.
My thought is compressed natural gas likely provides the best reduction in CO2 for the dollar vs any hybrid currently being suggested. The technology needed to build a natural gas truck is well understood, and natural gas is lower in cost at this time than diesel. Of course once Uncle Sam starts to tax the bejesus out of natural gas, things may change.

Personally, I like Diesels that use Natural Gas as well. IIRC, the highest ratio on a diesel vehicle is 70% Natural Gas / 30% Diesel... And from what I have been looking at, you can run on 100% diesel if need be. at least on my personal F350 that is the case. The gas engine 350's can run on 100% natural gas, but I don't like the gas engines on the truck. Either way, this setup can helps to offset the chance that you either can't get Natural Gas or the price jumps really high.
