The main difference between the Peterbilt 388 and 389 is the length of the hood. The Peterbilt 389 has a longer hood, measuring 131 inches, compared to the 388's 123-inch hood, which gives it a more classic, elongated appearance. Additionally, the 389 is often considered the successor to the 388, with some updates and improvements in design and aerodynamics.
