Here is a little question I keep asking myself.

We all know the D4-d is a pretty good turbo'd engine.
Pretty good power, not really a slug on the motorway.

However, how does altitude change things ?

I know the normally aspirated diesels, suffer greatly from altitude sickness.
How much affect does it have on the newer engines, with all the ecu, compensating airflow, fueling pressure, and injection timing ?

What is the sort of dizzy heights the 120 owners have driven their vehicle over, and what was the feeling of any sort of drop in power ?

Having just been 5000ft up the Massif Central on the Raid Asterix, I can tell you my D-4D pulled like a train at altitude - I was VERY impressed ;)
