2011 GMC Terrain SLT-2 4dr SUV (2.4L 4cyl 6A)
Dealer claimed 22 city and 32 HWY and I have never gotten better than 23 MPG and that was on a road trip with all highway driving. I only purchased this car because of the MPG. I would never have purchased had I know GMC lied about the MPG. I typicalley average 18-20 MPG with city and highway driving combined.
