The 2013 GMC Terrain has completed its final testing and GMC reports that the new, 301 hp, 3.6-liter V6 is more powerful, yet has the same fuel economy ratings as its predecessor in the 2012 GMC Terrain. The V6, which is be optional in the 2013 Terrain, will go 0-60 mph in 6.7 seconds, according to GMC engineers. Terrain's lead engineer Essy Ipakchian also said that drivers will notice "improved passing power with fewer downshifts, as well as stronger towing performance."

The new V6 has a maximum towing capacity of 3.500 pounds. EPA-estimated fuel economy is 17 mpg city / 24 mph highway for front-wheel drive models and 16/23 mpg for all-wheel-drive versions.

The new 3.6-liter V6 replaces the 3.0-liter V6 in the 2012 model. It will be a $1,500, stand-alone option on the SLE-2, SLT-1 and SLT-2 trim levels. On the 201`3 GMC Terrain Denali, it will be packaged with upgraded 19-inch chrome wheels for an extra $1,750.
