Thread: It's official isuzu is the best

Absolutely make the engines and transmissions common and optional throughout the range.

However when you talk to LRA and people in the know at JLR UK it seems that they want their engines in particular to be exclusive and related to the status of the model. i.e. the L322 and RRS will be the only models to get the supercharged V8 petrol likewise the TDV8, the D4 gets the TDV6 while Defender gets the 4cyl Puma diesel.

Why can't someone who wants the size of a D4 be able to option the TDV8 to tow their 36' caravan while doing the big lap. Similarly the Defender get the TDV6 or TDV8, but as I said before the bigger the capacity, the greater the CO2 output over greater numbers of cars and they get punished by EU enviro laws.

Sorry, I don't buy that.

Yes but Toyota, Mitsubishi, Nissan and Mazda manufacture and sell thousands of small shopping cart sized cars to offset the CO2 outputs of the larger vehicles.

Land Rover have no such vehicle in the market to offset the CO2 emmissions against and it is probably a part of the reason for the development of the 2WD Evoque with stop start technology.

It's all part of the obtrusive EU environmental laws.

The other problem, they'd have to replace almost the entire driveline.

2.5 diesels have no problems powering some bloody big vans and fast utes. 450Nm and 190hp is becoming standard.

My Navara has 450NM out of a 2.5L 4 cyl. Does so quite nicely and in the wet almost as much fun as our SS utes just not the same noise.

I drove all the twin cabs and the only one that performed better was the smaller engined twin turbo VW ute.

@Dougal:

Yeah, I hear you, but 2.5 common-rail direct inject turbo-charged and intercooled diesels are highly stressed animals.

AFAIK, if it's not a proven high mileage unit, it's no good. Nissan is starting to get problems with the YD25, even down-tuning the ECU on the sly from what I've heard so that they don't start drowning in warranty returns.

As was mentioned above: offering a bigger TDi engine with one of the existing auto boxes is possible from the current line-up (TDv6, TDV8) and hardly a major re-engineering effort. Some guys on this forum would do that in their sheds on the farm......

Didn't think about the emition laws that's a good point its all a load of crap the sooner they relise it isn't making the world better the better everyone will be LR don't make the tdv8 3.6 now due to the 3.0 tdv6 making almost the same output for less emitions but now have the tdv8 4.4L... Dougal that's alot of power but ill say something that sounds like something you would say and that is "i still know which one I would prefer"

You can make small very efficient engines to the job of much larger engines, but to do it the engines are running under stress at or close to their limits. Using a larger engine particularly when it's made more efficient, means that it doesn't need to work close to it's limits and from that should be more reliable over a longer lifespan.

Isn't that why we like the 4BD1 and particularly the 4BD1-T?

Good point! If you take a look at the navaras d22 and d40 both 2.5ltr but the d40 is 30kw more
