I just got back from a 2,500 mile road trip to Colorado, and this car ran like a dream. I've owned it for 18 months, but this was the first really long trip, and I have to say how incredibly impressed I was. I left it in Mountain driving mode pretty much the whole time, and even going 80+ mph up mountain highways were not a problem at all. It had pickup when I needed it, and performed flawlessly while averaging 44 mpg. Had plenty of room in the back for our family of 4, and everyone was very comfortable. I also loved the on-board maps when we didn't have service combined with using CarPlay when I looked up something on my iPhone and then could just plug it in and go. Really pleased - great job, Chevy!
