But it's a nonsense design, the caps on the big ends etc are freeze cracked with no tabs to stop them spinning, spin and cut off oil supply. Even Morris Minors back in the day didn't spin bearings unless you ran them with no oil. Its utter junk and due to costs, its cheaper to do freeze cracked ends than machine them properly, cutting costs results in shite reliability. Same with the plastic impellers on BMW water pumps, cost cutting.
Yet LR keep trading on their past reputation.

That sounds a colossal number, but not altogether surprising - a quick googl reveals that they sold over 430000 vehicles worldwide in 2020/21, so that makes them about six months behind.
Actually according to JLR themselves
"Our products are in demand around the globe and in Fiscal 2019/20 we sold 508,659 vehicles in 127 countries. We employ some 40,000 people globally and support around 250,000 more through our retailer network, suppliers and local businesses."

That was mostly before Covid or component shortages.
Next year… "Our class-leading Jaguars and Land Rovers are in demand around the world and in Fiscal 2020/21 we sold 439,588 vehicles in 127 countries"

However their production capacity excluding China’s joint venture is about 550,000. Probably far more considering that it includes Jaguar where production is only at about 25% of potential.

So at the face of it, it looks like they have six month’s worth of orders but since the turnaround for a factory order in the most efficient European plants is three months and that the JLR factories are not running anywhere near full capacity, I suggest that their order book is far less healthy than the face of it suggests.

I suggest when the world runs out of money they will be on a three day week as will a lot of stuff

You may be right - I had taken the 430k figure from the same source that you appear to have found it. The production capacity in China is apparently 130000 per year, but I imagine a combination of Chinas attitude to Covid and the shortage of chips has curtailed its potential at least as much as it has done to the UK, Slovakia, India and Argentina factories.

It is true, the Ranger get a variation of the F150 V6 diesel which is a PSA/Ford derived engine.
They've reworked the heads and crank to a steel forged one and now a compacted iron graphite block , but in essence it is the v6 lion.

Still the impossible to replace rear HP pump belt and the oil filter is still 6 miles away from the oil pump and the intake manifolds look the same as before, so one of those will burst!

They're saying a design life of 150,000 miles.

They have always had a compacted graphite thin-wall cast iron block. The reworking is minor and mostly just rejigging the layout to suit various new applications. It is now assembles in Mexico where most of the metal was always sourced. The V8 diesel has been assembled in Mexico from the start.

It is still too short to have a strong enough crank for longevity. Land Rover’s straight six is potentially a far better engine but as usual with these companies they cheap-out on critical components such as timing chain tensioners.

3 discovery’s no electrical or gearbox issues yet! Yet!!!!

I’ve certainly no brand loyalty I think the 90 is horrendous and think people who drive them must me be clinically insain,

But there’s nothing else much with 6/7 seats that tows 3.5 tonne simple as that plus there extremely nice to drive, I’d be open to something else that’s a cheap to run in that class std?

A design life of 150,000 miles???
Ffs that's 25% of a Landcruiser engine and half of my 4G63 that's never been dismantled and runs as good as when it was new!!!

Ironically Fords best engines were actually made in Australia!!! The Geelong cast "Cleveland's" and the 6 cylinder Barra were vastly superior to any comparable Ford or GM engine of the period.
Now a new Ranger with a Barra, decent ZF or Asian transmission, centre and rear diff lock and optional front diff lock would well and truely be a Toyota beater.

Yes still here, with 72K on it, just needed a new alternator last month, otherwise its just been brake pads all round. I did have a look at the last new ones on sale but none had the spec I have... seems it was loaded with nearly every option. I looked for heated and cooled seats but non did so kept the old one.

I have no idea what I would replace it with, dont want a Land rover badge (dont like walking!) or a VAG car, Merc and Audi are for disabled drivers who cant move an indicator stalk, and the top Ford Kuga is a bit of a backward step
Something from Japan or South Korea?
