That's a decades newer engine design, in a smaller vehicle, and a much smaller engine. I'm not sure if everyone here realizes this is a late 70s or early 80s Volvo. The late 70s/ early 80s Volvo diesel uses a 6 cylinder version of the VW 4 cylinder engine used in the old Golf/Jetta, and is a historical precursor to the more efficient engine in your TDI. It was incredibly advanced and efficient for its time- it's competition, the Mercedes 300TD wagon, only got 22mpg at the time, and gasoline station wagons of that size would be lucky to get 15mpg.
