GM Announces Dual hybrid
The company that promised you hybrids were "of doubtful benefit" has announced that it will release a new hybrid technology in trucks and SUV’s in 2008. Using a combination of electric motors and timely deactivation of engine cylinders, the dual hybrid technology promises gains of 25% on current fuel economy.
The Good: The system works and has been tested in busses for several years.
The Bad: Unfortunately, since GM plans to launch this technology in trucks and SUVs that are anything but efficient, the actual savings will be meager (23 MPG instead of 18 for a Chevy Tahoe).

What bad? There is no bad. 25% is 25%, and saving 25% of the fuel on a 18 MPG truck saves a lot more gas than 25% on a 40 mpg car. And, because of the large number of gallons saved, the amount of time to recover the cost of the technology in the truck is much less than the time for a higher efficiency car. This is all good.
