So what the heck is the XL? Think of the Envoy XL as a longer, stronger version of the popular Envoy SUV. Introduced in 2002 and retired in 2006, the XL increases the Envoy's seating capacity from 5 to 7 so you can carry more people with ease. The power train in our 2003 Envoy XL is a 5.3-liter Eight Cylinder. All that power keeps you situated on the road, rain or shine! In the end you have a safe feeling of road gripping power! The XL means increased passenger capacity or fold the seats for more for cargo, this XL handles a minimum of 23.4 cubic feet.
