The SD4 is the old engine, Tombie. The new one is the TD4 132. Same power, near enough, but 2.0l instead of 2.2l.
In the test posted by the OP they mentioned the engine groaning due to the low revs, which I referred to as grumbling. At 100kph the engine is doing only 1250rpm and even groans then. That is the main thing that spoils the otherwise excellent engine but it seems to be the price you pay for going for absolute minimum fuel consumption. I tried it in sports mode the other day but it still keeps the revs at 1250 when possible. Its not really happy until a bit above those revs.
We get 7.5l/100 on both trips and driving around the suburbs.
