2009 GMC Sierra Enhances its Fuel Economy

June 24, 2008

DETROIT - For 2009, the GMC Sierra lineup enhances its segment-best fuel economy with a new six-speed automatic that is paired with V-8 engines (except the 4.8L). Additionally, the 6.2L engine previously exclusive to the Sierra Denali is offered on SLT crew cab models; it is also more powerful than last year’s model and E-85-capable. Other new features and content changes give customer more choices that support both safety and convenience.


A Sierra Hybrid model also is available beginning in 2009 and it delivers a 25-percent improvement in overall fuel economy while offering Sierra’s traditional capabilities — including a 6,100-pound (2,767 kg) towing capacity.
