I'm pretty sure it's mostly about gearing just like with any vehicle/engine. If the vehicle doesn't have gearing that puts the engine in a nice part of the BSFC map when cruising then the driver would need to P&G to see better mileage. This can happen w/ a diesel, gasser, even LPG powered vehicle. The specifics depend on the gearing versus BSFC map, but it's possible to have a TDI w/ poor gearing given the power requirements when cruising.
