I spoke to a diesel S Type owner today. MPG shock.

[Benbay001]

They said they were getting 31 mpg from their 2.7l S Type diesel.
They were about 70 y/o, so i can only assume that they drive a lot lot slower than i do too!
Makes 20 mpg bearable for my STR.
Are the later Jaguar Diesel engines just as uneconomical?

How long were his journeys?

If I do sub 10 mile journeys in my XF Diesel, it'll struggle past mid 30s. If I do a long motorway journey and stick the cruise on about 0.76 leptons, I see low 50s.

Completely meaningless. What is your average fuel consumption, month after month?

Why is it completely meaningless? If the 2.7 from the first post only does 8-mile journeys, then 31 is pretty good. My overall average is 40, but if I just told you that, it would be meaningless as it has no context.

Hi

I used to own an 05 plate S Type and the life time average after 70k was 37mpg

Pleased to say I picked up another S Type yesterday (07 plate), computer 'B' was showing 6k with 38.2 mpg from previous owner, I drove the car home 140 miles from previous owner mainly on dual carriageway, so 70mpg and many round a bouts, didn't hang around with acceleration (enjoyed the car!), stook to 70mpg as there were a lot of campera's, and averaged 43.2mpg. Obviously will expect this to drop a little when I do a few local town runs.

Hope this helps

I get an overall (brim-to-brim - not computer) 38mpg, with a range from 44mpg charging through France and Italy for the Mille Miglia, to 32mpg in winter on very short runs.

Just got back from France again and the last fill-up yielded 43mpg.

I don't get the idea of anyone buying a Jaguar for economy as opposed to performance.I'd be surprised if 'charging' in this case means around 10 hours total from Calais including fuel stops and using one of the alpine passes and over an equivalent distance as Monza for example.

if your normal use was a 30 mile each way commute on DC/ motorway and then various stuff at the weekend you'd have a different average than someone who commutes 8 miles a day through congested stop-start traffic and doesn't leave town at t the weekend

Exactly.

I didn't buy it for economy, that comes as a bonus; I bought it for the monster mid-range torque and the sublime compromise between pinpoint handling and the waftiness that comes with a Jaguar.

The 'charging' bit was more a reference to the return drive from the MM via the Route Napoleon and the Tarn gorges.
