They won't arrive in dealer showrooms until the fall, but the new Chevy Silverado and GMC Sierra pick-ups are already making headlines. Some of them will be made in Flint at GM Flint Assembly.
General Motors says they'll get up to 24 miles per gallon highway.
The all new pickups will come with an all new engine. The 4.3-liter EcoTec3 V6 engine is estimated by the EPA to get 17 mpg city and 22 mpg highway for 4x4 versions and 18 mpg city and 24 mpg highway for 2WD models
In a statement, GM claims the full-size pickup trucks will be "leading the segment in city fuel economy and helping customers save money through a host of fuel-saving technologies".
According to a GM statement, "EcoTec3 engine technology matches Ram HFEâ??s 18 mpg city, while 4x4 Silverado and Sierra models achieve 17 mpg city, the best of any full-size pickup".
