New model Ford Ranger has 3litre V6

Again that would be the lack of diesel.

Although to be fair I believe some F1 engines are (speculated to be) running compression ratios up around 18:1.

However the pressure rise in the chamber compared to diesel would be substantially different, therefore creating different torque loadings.

Don't forget the rpm they run as well, so they actually make a lot less bang (torque) per fire than you might imagine.

And it's likely that if you tried to run one for a couple hundred hrs you might find a number of parts leaving the crankcase in a hurry.

You also need to consider the development $$ spent on an F1 car and the cost of the parts compared our road cars. Look up the cost, it's staggering.


And the road car needs to operate under a myriad of circumstances whereas F1 is reasonably tightly controlled.

The 2.7 TDV6 oil pump pricing would beg to differ!

Big assumption there of 're-engineer'. VW have been involved in the T6.2 platform since 2017 - as such, it's highly likely that it was engineered from the start to suit their engines too.

There were many V6 petrol engines built over the years that were extremely reliable,but I suppose with no where near the high output of these modern engines particularly the torque of the diesels.

The Tojo V6 petrol comes to mind,started at 3.4L then went to 4.0L,sold all over the world and fitted to many different vehicles with virtually no issues or breakages.

I loved the V6 Ecotec i had in my VS ute. Light on fuel and heaps of power.

(Based on Buick V6 sold in zillions)

Yes I forgot about that one,I had a six seater wagon,great vehicle,fantastic on fuel,but the brakes were never up to the task if it was driven enthusiastically.Very reliable as well.
Coming from a 202 HZ,anything that sort of era(90’s)was better[biggrin]

I think the original LR 3.5L V8 also came from that stable?
Although weeping heads,and later on slipped liners were a continual issue.

Came across this video today, whilst it doesn't directly comment on what I've written here before, the guy presenting it might do a better job than I have in explaining it!!

This video is not what I was basing my previous comments on, as I mentioned, the first time I ever saw it was 10 minutes ago.

If you have a think about what he says, the gist of what I was saying earlier might make more sense.

Dont the majority of prime movers use V8's though ?

I though the same. But a quick look on the Kenworth and Mack sites, and both use inline 6. Kenworth a Cummins and Mack a 13ltr Mack unit.

I have a great book on balancing engines from the 60's which points out pretty much the straight 6 and V-12 can be perfectly balanced (and boxers, but they're something else entirely), anything else is a compromise. It's not like you can't build a V6 to last.

It's actually much simpler, the V6 engines found in land rovers have design problems.
