I was initially displeased with the new GMC Terrain being offered with only a 1.5 or 2.0 Turbo 4 having the 3.0 V6 in my 2012 Terrain now, Which I am very pleased with. But from what I have read the 2.0 Turbo 4 does a decent job accelerating the not so compact 3,800 lb Terrain Denali to 60 in about 6.5 sec. As expected the standard 1.5L Turbo engine is under powered for most folks, Probably OK in the Chevy Malibu Though. I have never driven a Turbo engine before, But am willing to give this new Terrain a try when its time. I hope I get better luck than my neighbour's new Ford Escape which when he lets off the gas with the 2.0L Turbo approaching traffic, and stomps it to pass, It dies long enough to scare the pants off you. Pretty scary, Even dangerous on a 2 lane road. I wonder if other cars have the same problem. I didn't see any reference to turbo lag with GM's engine yet. Despite modern technology, It seems turbo lag is alive and well. I just read references to Ford turbo V6's exhibiting the same frustrating and dangerous turbo lag in their pick-ups. This doesn't inspire confidence. But it seems we have little choice today for many small and mid-size cars and SUV's. For trucks, I suggest stick to a V8. GM for one offers some good ones.
