In 2004, GM redirected resources from the development of new sedans to an accelerated refurbishment of their light trucks and SUVs for introduction as 2007 models in early 2006. Shortly after this decision, fuel prices increased by over 50% and this in turn affected both the trade-in value of used vehicles and the perceived desirability of new offerings in these market segments. The current marketing plan is to tout these revised vehicles extensively as offering the best fuel economy "in their class" (of vehicle). GM claims its hybrid trucks will have fuel economy improvements of 25%.
