JTD 1.9 16v vs 2.4

Changes in job mean I will double my mileage so a 156 V6 may prove too
costly. If the figures stack up I may need to consider trading in for a JTD
at some stage in the future. The 175 bhp 2.4 looks quite appealling,
especially as the 5 cylinder at least makes an interesting noise.

How does the 1.9 16v 140bhp compare? How does it sound and perform?

Also what real world fuel economies are JTD drivers getting bearing in mind
I will now be doing a lot of motorway miles. The V6 gets into the low
thirties on a motorway run, low twenties every where else.

I'm still rather old fashioned when it comes to diesels, clattery things
that run out of revs half way round the rev counter...

Cheers
Tony
