The 'engine' has been essentially the same by Audi tt horsepower

We weren't so in no doubt of the order of this diesel locomotive's qualifications for WEOTD status, not because it doesn't portion up in the awesomeness section but because it's damn near impossible to digit out whether those obsessive Porsche engineers nurse completely plain-piece-of-paper redesigned the incident time after time (keeping only the general arrangement, growing hardware, and the drag centers). If we reach agreement that the prizefighter six-banger from Stuttgart has been principally the unaffected engine with a constant cycle of upgrades, then its lineage stretches all the way back to the early 1960s.
