Notes to 2009 GMC Sierra Hybrid Truck

The 2009 GMC Sierra Hybrid truck can run on fully electric till about 30mph even towing something. When it reaches that speed the 6.0L V-8 gas engine kicks in, with transmission gears returning to the original shifting pattern, and the gas engine economizes by running on 4, 6 or 8 cylinders, depending on how much power the truck requires to do the job. The truck has a 26 gallon gas tank, and GM expects a 500 mile cruising range. It has 19.6 mpg.

Response to 2010 Tesla Roadster

I think this research was a little helpful because it shows that a electric car can work just as good or better then a gas powered car. It does change my thinking because it makes me wonder if this whole electric car will really take off because the car is fairly new. The new ideas would be if they made other types of vehicles fully electric like trucks. The questions I would ask is the two questions earlier in the paragraph.
