General Motors will sell the first of its "two-mode" hybrid vehicles in the fall of next year, according to Edmunds.
Two electric motors will work in tandem with a new V-8 in a GM Sierra or Chevy Silverado, or both. GM also developed a computerized fuel management system to optimize the transmission and balance between the engine and electric motors.
For a premium of $3,000, owners will get a truck that average 25 mpg and has 365 horsepower, up from 300 for the current GMC Sierra 2500 model.
If it lives up to the promise, the new hybrid technology could reverse slumping truck sales are resuscitate GM as drivers will get more accustomed to the higher prices.
