2013 sees a new 3.6l V6 added to the range. More powerful than the 3.0l it replaces, fuel economy remains similar according to GM. A top of the line Denali trim is also new for 2013. The 2.4l four-cylinder is unchanged and all-wheel drive is optional on all models. A six-speed automatic is the only transmission available. The long wheelbase combined with a wide track greatly contributes to the comfortable and reassuring handling.
