Chevy Volt Receives Preliminary Electric Rating, May Mean 100 mpg
The Chevrolet Volt will use electricity to move the wheels at all times and speeds and so General Motors is asking the EPA to certify the Volt as an electric vehicle. But the volt has a 1.4 liter naturally aspirated gasoline engine as well as a plug-in battery pack, and is therefore a hybrid.
CARB, the California Air Resources Board, has already given the Volt preliminary certification as an electric. The reason it matters is that the Volt would become the first vehicle rated at 100 mpg, a huge marketing edge for GM.
2008 Chevrolet Tahoe Hybrid Lightened Using Aluminum
The 2008 Chevrolet Tahoe Hybrid is the perfect example of a vehicle boasting a weight savings as a result of an expansive use of a lightweight material - aluminum. According to the United States Geological Survey (USGS), aluminum weighs about one-third as much as steel or copper; is malleable, ductile, and easily machined and cast; and has excellent corrosion resistance and durability. It’s use in auto manufacturing improves safety for occupants; performance, drivability and longevity of cars; and is easier on the environment.
