The midsize Colorado offers efficiency thanks to the XFE model that achieves the lineup's best fuel economy. Also available is a 5.3L V-8 engine on extended cab and crew cab models that enables a towing capacity of 6,000 pounds (2,721 kg). The 5.3L features variable valve timing for greater overall performance. Head curtain side air bags are standard on all models. The Colorado's enhanced brake system features four-channel ABS with yaw control for flatter, more controlled stopping during panic stops and improved control on slippery surfaces.
