General Motors isn't saying how it plans to do it, but according to our friends at, it is saying that consumers are "...going to see substantial improvements in towing capability in our next hybrids." Right now, the Chevrolet Silverado Hybrid and GMC Sierra Hybrid can pull 6,100 pounds with their electrically-assisted, multi-displacement 6.0-liter V8 engines. The improvement will be "up to 50% more," meaning a tow rating of 9,000 pounds could be coming this way.

If GM can wring a full 50% improvement out of the drivetrain, that would put the hybrids just 1,600 pounds short of the max towing capacity of the standard gasoline V8 crew cab half-ton with the enhanced tow package. The transmission torque capacity and the necessary cooling systems are the apparently the chief limitations to be overcome, and GM says if the current package can evolve enough, then "one of the things you might consider is E-Flex." And how neat would a Volt pickup be?
