The Freightliner FL-70 and M2 are both medium-duty trucks, but they differ in design and capabilities. The FL-70, produced primarily in the 1990s and early 2000s, offers a more traditional, rugged design, while the M2, introduced in the early 2000s, features a more modern aesthetic and enhanced driver comfort. The M2 typically boasts better fuel efficiency, improved safety features, and a wider range of engine options compared to the FL-70.
