Oddly enough, out of all of the research done into hybrid technology GM has been forward thinking enough to make theirs are not only affordable, but ingenious as well. They now offer both the Sierra and the Silverado pickups as hybrids country wide. Using a technology not formerly seen in hybrids, GM attempted to not only lower emissions in their pickups, but to make them handier as well.
Affordable Technology
GM wanted to make a hybrid truck that was too well priced to turn down, the major complaint of the hybrid models is high price tag which counteracts the gas mileage benefits. In response to this GM produced their pick up hybrids to cost only $1500.00-$2500.00 more than its gas guzzling brothers, saved with tax cuts at the pump within the first few years of ownership. Especially if you consider that the hybrids produce a 10% improvement in fuel economy, all without sacrificing any power.
Both the Sierra and Silverado offer the same 245 horsepower V8 engine, and can tow up to 7,700 pounds. If you consider that pickup truck drivers are not sacrificing any power and when sitting stopped in traffic it emits very limited pollution for their size.
Hybrid System
GM employs what they call a "flywheel alternator starter hybrid system" which uses a compact electric motor incorporated between the engine and the transmission. This electric engine runs the truck when it is slowing or idling at a standstill. They calibrate the flywheel alternator system to turn off the engine more frequently than even those systems used in most smaller hybrid models. Eliminating much of the pollution caused by slow moving traffic in high volume.
Now Your Work Truck Can Double As A Generator
Both the Sierra and the Silverado boost four 120-volt, 20 amp three-prong outlets which can be used to provide power for electrical tools and electronics. This eliminates any need for a gassy generator spewing fumes into the air at a work site. The truck must be running, but utilizing it's electric engine allows it to run virtually emission free. GM reports that their hybrid trucks can continue to pump out power for up to 32 hours non-stop before needing to refuel. Aimed specifically at contractors, whose need to access abundant sources of energy and drive long miles to job sites fuel this intelligent new take on a work truck.
Testers Report
The power source for tools was not quite as juicy as GM would have you think, however the idea is a brilliant one. No doubt in a few generations they will have nailed down this imperfection in an already forward thinking vehicle.
Although the gas mileage is a tad better overall, it borders on insignificant. Which again is certain to be addressed and updated in generations to come. Reviewers say that the feel of the engine cutting out as you hit ten miles an hour is a bit disconcerting, and takes some getting used to, but its pollution saving benefits far outweigh that small detail. Every accessory on the truck is electrical, so the gas engine only runs when it is needed to for its sole purpose, to accelerate the vehicle.
Overall Appeal
The brilliance behind the ideas developed for these pickup truck models is really what drives them at this point. Fine tuning is necessary of any piece of equipment and GM has been making pick up trucks for a long time. They will continue to address the issues and refine the existing good points, driving the hybrid market to continue to bring us new and innovative ideas.
