Bob Cher Posted August 12, 2008 Share Posted August 12, 2008 We have a CI on a 2006 2ltr Fiat Ducato. I have been trying to find out what the economical cruising speed is and what the engine powerband revs are. I have searched through the technical data from Fiat and even tried the Fiat web site to no avail. Are there any clever people out there who have this knowledge. We would be forever grateful.

Philman Posted August 12, 2008 Share Posted August 12, 2008 Hi, forgive my ignorance but is it a petrol or diesel? Mine is a 1.9TD and I find it is best between 55 and 60 on motorways and dual carriageways or 40 to 45 on other roads. Phil. Link to comment Share on other sites More sharing options...
Guest Tracker Posted August 12, 2008 Share Posted August 12, 2008 Depends on the wind speed and direction quite a bit on Motorways! The 2.0 hdis that I have had would happily plod along at 45mph or could be pushed along a level motorway at 75 for many miles - dropping off significantly uphill. At 45 mph I got about 35 mpg and at 75 mph I got about 25 mpg - in round figures and at 55 I got about 30 mpg. A suitable cruising speed is one at which you and your passengers are happy and feel safe as the modern diesel engine is pretty durable and will happily oblige you with whatever speed you feel like on the day. I now have a Fiat (old shape) 2.3 and this does similar mpg at similar speeds - but it maintains speed uphill and into a headwind much better - and will really fly on the Autobahn when asked! The day I have to worry about mpg is the day I will stop motor caravanning because I like to travel quickly when I have a long way to go and want to get there quickly, and slowly when once I have got there and want to explore without regard or worry about the fuel bill.

Derek Uzzell Posted August 13, 2008 Share Posted August 13, 2008 A July 2005 MMM report of a Swift Sundance gave output figures for its 2.0JTD Fiat motor as 62kW (84bhp) @ 4000rpm and maximum torque of 192Nm (141.5lb.ft) @ 1900rpm. I don't have easy access to the 'power curves' for this motor, but I've got the graphs for a similar capacity Ford Transit DuraTorq engine that produced 63kW at 4000rpm, though its maximum torque (230Nm at 2000rpm) was greater than the Fiat's. Assuming the Fiat and Ford motors have roughly similar power-delivery characteristics, I'd expect you'd get best economy in whatever 5th gear cruising-speed range 1900rpm to 2500rpm produces, where the Fiat motor's torque curve is likely to be pretty much flat-topped.

Bob Cher Posted August 27, 2008 Author Share Posted August 27, 2008 Thank for your help folks, unfortunatly we would love to just get to our destination without worrying about cost but as a retired ex-service man we have to watch the pennies. Thanks again Link to comment Share on other sites More sharing options...
tricky dicky Posted August 29, 2008 Share Posted August 29, 2008 The Peugeot Boxer website and brochure show maximum power for the 2.2 l HDi 100 bhp engine at 2900 rpm and the maximum torgue at 1500 rpm. Also gives graphs of output at different rpm. Link to comment Share on other sites More sharing options...
