RRSman, I have just had a long chat with our mutual friend at LPR, and what you say about disappearing diesels appears to be right, which is a pity as petrol engines emit far more Greenhouse gas emissions than diesels emit NOx and particulate.


Do you mean disappearing from the whole LR range?? Shocked If so, on what sort of timescale?

That's simple, I'll no longer be a LR customer, and only purchase makes that stick with Diesel.

Most London parking where they charge extra on "certain" diesels I have found I don't get charged, they have a "Polution figures" book and the RRS SDV6 HSE comes under the limit they charge for, the date is only to scare people, but if you check they will consult the guide, otherwise no point in having all the extra equipment on your car to reduce emissions.

Also found that if your car is registered as "Disabled" class, you are exempt from these stupid extra charges. John

Dissapearingvdeisels is more about getting out of any Ford diesel.
When Ford sold JLR to TATA, there was an agreement on the price of the engines from Ford. When that was coming to an end, it was cheaper for JLR to design and build its on straight deisels, hence the 4 cylinder and the upcoming 6 cylinder straights.

The v6 and v8 are Ford built diesels and I can see them dissapearing.

As for petrols, well, expect those to change to straights too in most usages, making tge the old V's specialist uses..

Just hope they don't suffer in the 6's from crank whirl ussu4s...(cough, cough) Just bought a RRS 06 MY HSE TDV6 136,000 miles, to be a second car to my bland, boring Mitsubishi Outlander 68 plate 2.0 petrol 4

Diesel sales have supposedly fallen by 20%:

Modern petrols have made diesel almost redundant in "cars". Where diesels used to do much better on fuel and CO2 emissions, petrols are right up there on fuel use and CO2 is not the headline pollutant anymore.

You still get higher torque and over a wider rev, range out of a comparable sized diesel.

Peak torque is produced at lower revs in a diesel but the rev range is much the same. The petrol just does it at higher revs. Choose the right gearing and shift strategy and the fuel makes little difference.

Power accelerates. Diesel produces power at lower revs (called torque by the motoring press) where petrol produces power at higher revs. Petrol will produce higher peak power, for a given engine size, than diesel.

Power is torque X speed so you can produce the same power by having more or less torque at less or more revs.

The 4.4SDV8 produces more torque than the 4.2S/C. Which is quicker assuming each is driven in its working rev range? The smaller petrol.

The subjective performance of diesel is that it is "torquey" because it produces power at lower revs. This is nice when poolting about. But the petrol will be quicker when driven to its strengths I.e. with revs on the clock. Horses for courses and both will work equally well, e.g. towing, if the gearing and shift strategy is correctly selected.

Modern turbo petrols, especially in ordinary cars, have very wide and flat torque curves. They rival or better the equivalent diesel in many cases. 2012 SDV6 - it's missing a couple of cylinders

Exactly. Maximum acceleration in any ONE gear is at peak torque, but since we are blessed with gearboxes then maximum acceleration in ANY gear is at peak power. A petrol engine of a similar size to an Aga diesel will usually produce more power. How well one can use this depends on the gearbox.

The one major difference in driving characteristics between petrols and diesels is simple - throttle response.

I so miss the instant response of a decently-sized petrol vs my current diesel. MY2016 HSE D SDV6 - gone due to fuel dilution problems.

None of that alters my basic point, that diesel produces more torque for a comparable size engine. The 3.0l SDV6 produces 700 Nm compared to the 3.0l petrol (supercharged) V6 at 450 Nm. The SDV8 produces 740 Nm compared to the (bigger capacity) 5.0l (supercharged) petrol V8 at 625 Nm.

As regarding power, I'd rather pull a caravan out of a muddy field with a diesel than by revving up a petrol-driven car any day.

In my SDV8, I can do 70 mph at 1,750 rpm and still be getting excellent acceleration in motorway traffic. I'm not entirely sure where, in the UK, the petrol versions come into their own! (I also have a 5.5l Mercedes SL500, so have a car that will keep its performance going at peak well into illegal speeds, but don't really get full advantage out of its capabilities!).

(As an added bonus, I get an indicated 40 mpg on a 70 mph motorway journey as well).

I find the power and torque of the 3.0l SD suits my driving perfectly although I would like a petrol engine. How practical would it be for LR to tune a version of the 5l petrol engine to produce similar figures to the 3.0 diesel and would it give decent economy figures?
