Go and have a drive of one.
I’d take one any day.

I drove an LS crewman recently. Yeah, hammers if you rev it, but a bit dull compared to a good diesel during normal driving.

I guess you adapt, but the main way to adapt is to rev it more, which is even worse for economy.

All hail the quad-turbo BMW M550d xDrive | Top Gear

The early ls1 motors needed to be revved to make them work, bit of a flaw imo as the peak wasn’t that high.
The beauty of a petrol v8 is the wide torque band.
Even a rover v8 with its low overall figures performs well as it will pull from 750rpm to 5000rpm.
And it it quite linear and smooth as it does it.
Unlike modern turbo diesels which have a very narrow torque band, press accelerator wait for turbo to spool , turbo spools power comes on then falls off, change gear wait for turbo to spool. That’s why they need so many gears to keep them in the narrow band.
2speed powerglides were all that was needed for large v8 because of the nice wide power delivery before fuel economy was an issue

Well, good modern turbo diesels, particularly twin turbo types, spool quicker than a petrol will pickup, and they will rev enough to snick into the next gear, which isnt far away with modern multispeed autos. They change gear so quick there is no meaningful loss, and because of the oozes of torque they dont need to rev much.

Let me guess, like the ones on those Amorok’s.

Rammy i agree when it comes to 4wding. 4wding is about drivong as slow as possible and as fast as necessary and nothing is better for that then a diesel. 100% agreed.
However i reckon the big v8 goes alright. Sure its not ideal for the slow stuff but hell is it fun in the sand.

That plane stunt, not a good indicator.

Porsche Cayenne S pulled 314t aircraft last year

Yesterday arvo at boat harbour in kurnell.
Lets just say the y62 loves the sand.
