If you're familiar with the 2008 Tahoe/Yukon Hybrid, then the Silverado Hybrid will be instantly recognizable. The 2009 Chevrolet Silverado Hybrid shares the same two-mode hybrid transmission, 300-volt nickel-metal hydride battery pack and aluminum-block 6.0-liter pushrod V8 as the full-size hybrid SUV twins. This transmission packs four fixed gear ratios and two 60-kilowatt electric motors with planetary gearsets into the space of a conventional gearbox and forms the heart of the hybrid's namesake.
The approach taken in creating the Silverado Hybrid is not a carbon copy of the full-size SUVs, however. Unlike the SUVs, the pickup did not receive an extensive weight-reduction program, and as a result the Silverado Hybrid weighs about 300 pounds more than a comparably equipped non-hybrid Silverado. The pickup also wears a less extreme front airdam than its SUV brothers in order to provide a more useful approach angle, which is the kind of real-world issue you'd face on a job site. ...

Re: Silverado Two-Mode Hybrid
Not to argue an old thread Bob, but the Silverado did go through a pretty extensive weight reduction program. They took 300 pounds out of the vehicle so that the 600 pound hybrid drive train increase would only amount to a 300 net increase. Hense, no drivers/passenger seat memory, chrome clad aluminum, wheels, no LTZ interior, and many more less noticable minor changes to get the weight down. But the aerodynamics are less than desirable as is the case in a "pickup". I think they did a great job in the give and take department to reach an adequate compromise to deliver a great vehicle. Not the mileage some may hope for but in a pickup, not bad. Way to go GM!

Re: Silverado Two-Mode Hybrid
What kind of mileage does the hybrid Tundra or Sequoia get?
Those Toyota pickups do have that progressive weight loss system as their frames rot out over time. Then they lose the weight of the spare tire and other components as they fall off the truck. Very clever engineering.
