The 2011 GMC Terrain is powered by an Ecotec 2.4L four-cylinder engine with variable valve timing and direct injection technology that helps the Terrain achieve a segment-best EPA-estimated highway fuel economy of 32 mpg. Maximum fuel economy is achieved in part with an “eco” mode that is activated via a console-mounted button. When engaged, it lowers the torque converter lockup speed of the standard six-speed automatic transmission to 1,125 rpm to help save fuel.
A 3.0L DOHC direct injected V-6 engine delivering 264 horsepower (197 kW) is optional; and for 2011 it becomes E85-capable. Like the Ecotec 2.4L, the V-6 is backed by six-speed automatic that helps save fuel through reduced engine speed at highway speeds.
Terrain is offered in front-wheel-drive and all-wheel-drive models, in SLE and SLT trim levels. All models include four-wheel disc brakes with StabiliTrak electronic stability control and traction control, as well as six standard air bags: dual frontal air bags; head curtain side air bags and pelvic/thorax seat-mounted side air bags.
