Yeah, as I've said before, in the near future, vehicles which emit harmful pollutants will be banned from city centres.Quote:

If a diesel Defender was only marginally dearer than the 2.0 petrol I would go diesel (unless the petrol 6 was not much dearer than the diesel.... that would be a hard choice especially if the petrol 6 driven lightly when touring and loaded was pretty frugal).

All about Jaguar's New Hybridized, Supercharged Turbo Engine
Apparently the generator is belt driven?
The issue with petrol is when touring,having to carry it in the vehicle,particularly remote area touring.
Sure fuel containers can be put on a rack,but that is not always practical,and when full are quite heavy.
Land Rovers traditionally have had smallish fuel tanks,which doesn't help the issue.
That 6 cyl petrol engine looks extremely complicated,more complicated than a late model diesel.
Hopefully we will get to see a 6 cyl diesel shortly,which will replace the Ford V6 engines.

I would say a straight 6 petrol with and electric supercharger and a single turbo vs a twin turbo desiel v8 desiel would be a fair bit more reliable for multiple reasons. Toyota 1VD-FTV 4.5L V8 D Engine specs, problems, reliability, oil, Land Cruiser 200, LX450D
Wouldnt a petrol 6 supercharged and single turbo petrol have many less moving parts and less to go wrong than a twin turbo v8 diesel, especially when you consider how sensitive modern diesels are, bad fuel, hard use, dpf and dusting etc.
If a similarly powerfull petrol is just as close to same efficient and can carry as much fuel, the fuel carrying argument doesn't hold up when choosing which type of engine.
Also having run a modern v8 petrol in deep water crossings, they don't seem to get affected by water either.
For the above reasons for me, if there were two identical Ingenium engines one petrol, one diesel there seems to be too many reasons not to pick diesel these days over petrol.
Ingenium 6 only rear pictures exist for some reason? Top picture is Cruiser V8 Diesel.

I don't think there is a lot to choose between petrol and diesel for complexity these days. Historically, diesel has had two basic factors in its favour - it typically ran with higher compression ratio, giving greater thermal efficiency, and the fuel contains more energy per litre, both increasing economy compared to petrol, where a lot more energy went out the exhaust and into the cooling system.
In recent years petrol engines have increased thermal efficiency mainly by recovering energy from the exhaust and by using instantaneous computer control to adjust both mixture and ignition timing and using very lean mixtures most of the time (this control also allows higher effective compression ratios).
Both petrol and diesel engines have needed to greatly increase complexity to ensure that the exhaust meets emissions standards, but petrol has benefited from these also being used to increase efficiency, where there has only been a small improvement in diesel efficiency, and in that case there has also been a small decrease in efficiency driving some of the extras needed to meet emissions.
In the case of the Ingenium engine, both petrol and diesel benefit from a number of measures to reduce mechanical losses.
However, diesel still retains the advantage of greater energy content per litre, and also has the advantage of being more readily available in some more remote areas, such as those where there are restrictions on petrol because of its misuse, and where dieel is used for heavy transport and machinery. And diesel still represents a lower fire risk (thinking not so much the vehicle as in fuel handling, especially in very hot locations).
I think you missed my point,or i didn't explain myself correctly.[biggrin]Quote:

Sure,people have to be extra careful,but things happen,diesel is just so much more less risky.
Petrol engines, ATM,in light commercial vehicle,and large 4WD's have no where near the efficiency of diesels,particularly when loaded,and or towing.
Maybe the very latest ones with turbochargers and supercharges could be,but we will have to wait and see.I bet they have to run on premium fuel as well,which is not available in many areas.
Any engine can be effected by bad fuel,high tech complicated petrols more so,than low tech petrols,and dusting can also effect any engine.
Sure an engine such as the one in the current Patrol is way more simpler than a modern diesel,but those types of engines will probably disappear in the years to come as well.
If you have a good look into the faults with the LC V8 engines,that have been around for approximately 15 yrs,and are currently fitted to over 250 000 vehicles,in Aus,many of the issues are not caused by the engine itself,it is other external issues that have caused the failures.Also many are very high mileage,having done over 500 000K's.
And NO we don't want to get into a Tojo discussion again,or a petrol verses diesel argument,just a friendly discussion.[biggrin]
Diesel in a Jerry is a lot safer on the roof than petrol. You can legally carry diesel on the rear bar in a Jerry. You can't with petrol. Plus if most of your mates have utes then they all have diesel so fuel sharing is a possibility in emergencies.
