I do hear a lot about diesel engines, more specifically how they have to be turbocharged and that they generally have poor acceleration etc. But why is this?

Well now that depends on what you mean by underpowered. There’s a reason race cars use gas but big trucks, bulldozers, ships, most tanks, use diesel.
If you want something that speeds up fast to launch you off a starting line, gasoline engines are built lighter as they operate at lower pressures and use a more volatile fuel.
If you want something that runs at a lower speed but at that speed provides much more torque for moving something large at a steady pace, diesel is the right tool.
Try to scale up a gas engine to run something huge? You’re going to have a bad time. Try to scale down a diesel to run something not so huge, like say a passenger sedan? You’re going to have a bad time.
