Erm, no, the dci comes in 1.5, 1.9, 2.0 and 2.2. The new 2.0 is 150bhp, trust me....
What he said
The 2.0dCi is a new engine to the Renault range, and can be had in two states of tune.
It is being phased into the range on the Laguna and Espace, but it's not available for the Megane yet. Renault have just phased-out the 1.9dCi 120 and replaced it with the Euro IV compliant 1.9dCi 130 (with particulate filter) for the 2006 Megane, Scenic, Grande Scenic, Laguna, Espace and Grande Espace.
The 2.0dCi 150 can be had on the Laguna with a manual 'box. If you want an Auto, it's still the old 2.2dCi 140 engine, I'm afraid.
The 2.0dCi 175 (yes, 175bhp from a 2.0 diesel!!!!) is now available on the Espace and Grande Espace, once again with a manual box. Here, the old 2.2dCi 150 (yes, 10bhp more than the Laguna for some reason) can still be had as a manual or auto.
Both states of tune for the dCi are Euro IV (and have particulate filter).
Back to the question about the Fiat diesels, the 1.9 115bhp engine is a JTD (i.e. unijet). The 1.9 120bhp engine is a multijet unit.
I suspect Fiat think there will not be much market for the 1.9 150 bhp 16v multijet engine as most high-powered diesel engines in the UK are bought by user-chooser company car fleets and more expensive Fiats (due to high depreciation) tend not to figure on most lease-companies books; I know quite a few people that can have various family hatchback on their list, but Fiat are often excluded
As for the high percentage of Abarth owners on here, that will be due to them being enthusiasts and having a real interest in the car. Not being rude, but most Stilo 1.2/ 1.6 owners will have bought the car 'cos it's cheap family transport and won't even know sites like the Fiat Forum exist; the 1.2/ 1.6 owners on here (who therefore don't fit into this catagory, so I'm not having a pop) will be the exception rather than the rule
