Despite the hybrid hype, I think they'll be long gone soon enough. Their real world mileage is much worse than claimed and they're only decent for slow, stop-and-go traffic. Unless a breakthrough in battery technology happens which allows pre-charging of your hybrid so that you get a few hundred miles before the gas engine even starts. I've done a fair bit of reading on these and the bottom line is: ALL HYPE.
I think this truck's got a shot, if they don't price it out of the stratosphere. Which they'll need to do (price it competitively) if they want to sell enough to drop their fleet average MPGs.

Hybrid isn't really all Hype something is going to have to happen at some point Gas Engines will be very phased out in the near future it's about expected. I do feel right now This Diesel Hype is a day too late for Toyota and People arn't going to buy these in large numbers like the Gas v8 Toyota provides
. Currently The 2nd gen Tundra tow's a pretty good chuck of space and will sell. I doubt strongly people are going to buy these in such large number's esp with the cost assoicated with it. With the New Caft standard's coming out Toyota is going to have to go back to the drawing board's and rethink it's master plan which too some degee is done year's in advance.
another option is Active Fuel Management (formerly known as Displacement on Demand) is a trademarked name for the automobile variable displacement technology from General Motors. It allows a V6 or V8 engine to "turn off" half of the cylinders under light-load conditions to improve fuel economy. EPA tests show a 6% to 8% improvement in fuel economy.
GM's current Active Fuel Management technology uses a solenoid to deactivate the lifters on selected cylinders of a pushrod V-layout engine.
