I’m wondering why it is that the biggest Diesel engine manufacturers sell in a 4x4 is 3.0L?

Excluding the Yankie trucks, there’s only a handful of exceptions that I can think of, like the D4D V8 in the Cruisers & the 4.2 in the Patrol. Even the G-Wagon 350d made by those lying-Germans is actually only a 3.0L.

There’s BMW that makes bigger but that’s not a 4x4.

There’s no more Cayenne diesel & even the Maserati 4x4 is only 3.0L

I suspect it’s related to emissions, but why not even slightly bigger?

Economy and politics

But how do those equate to 3.0L?

I think there is a tax levied on engine cc in a number of countries. Along with more efficient engines that produce higher power with lower ccs its probably an optimum for most manufacturers. Besides, Dizzys are notoriously asthmatic and they would need huge turbos if they got any bigger

A Diesel is sold on the basis of perceived economy, conventional wisdom dictates that anything bigger than this is excessive, lets be honest, aal the diesels ever bigger than this magical number were in luxury suv’s!

I think we in SA and Aus has contributed to this perception, in that we would not expect anything less from a “bakkie” in the flagship model, but the manufacturer sits with the dilemma of getting it past the environmentalists and the politicians!

So they give us the bare minimum we accept as well as conforming to “authorities”

A modern 3litre diesel can sail under the radar when it comes to emission taxes, as well as make sufficient power to satisfy the masses!

The Cruiser is exempt from this, pretty much a niche vehicle labeled as a work horse and as such can get away with more, it also has a noteworthy almost cult like group of followers who does not prescribe to environmental confabulation!

The same goes with American trucks.

You need to travel bad and rutted roads before you get into the real nature. We Cruiser guys does not care about city roses dying

Jokes aside I think 3.0l is the midway between economy, relative good power and torque. Excluding big yank diesels 3.0l are right up there with some bigger engines in power and torque.

When my wife still had the 2.0l VW bus I were the champion in stalling the 2.0l enine in manual guise. Good economy but lagged of idle torque.
Think that is the very reason for multi speed boxes to overcome the low down torque on small engines. Once above 1800rpm it were fine.
I can pull away with the 4.5 V8 Cruiser even in 3rd gear if I want to.

A 3.2 DiD is the optimal size for power and reliability. Best there is [emoji106][emoji2532][emoji51]

There hasn't been a 4.2 Patrol for many, many years...

I found one, but its a rare beast and I’m not sure sales figures are even worth mentioning!

Bentley Bentayga V8 4.0 diesel with not one, not two, but 3 forced insuction (sic) devices, well two turbos and a hair dryer on steroids! 320kw/900Nm

It’s sibling the SQ7 is not sold in SA

Some of you will argue it’s not a true offroader, but I’m willing to sacrifice some of my valuable time to test drive a demo unit should the manufacturer require a test[emoji12]

I also promise to really put it through its paces

Quack when you test drive that Bentley I want a front seat ticket.

Please do take their Tech`ies along cause they will have a hard time erasing fault codes. I mean someone must stop you from pulling fuses and stuff like you did on the v6 Amarok
