In addition to its use in all 6.2-liter-equipped trucks, the eight-speed transmission now comes with LTZ, LTZ Z71, and High Country trucks equipped with the 355-horsepower 5.3-liter V8.                    
                             
        
                        
				                    
                        
                    
                    
                        The Colorado will have to make up for the fuel economy numbers of the Silverado. With the more ubiquitous use of the 8-speed, overall fuel economy numbers are down.                    
                             
        
                        
				                    
                        
                    
                    
                        The articulating running boards are a great addition. They feel, look, and operate in a way that just feels neat.                    
                             
        
                        
				                    
                        
                    
                    
                        In terms of outright attractiveness, the Z71 is our winner. The higher price leads to less brightwork and an overall cleaner look.
