Toyota's 4.5L TDV8 blows goats

For a so called offroad vehicle that is such a terrible engineering decision.

Not that unusual, leaf spring patrols were the same, long before Toyota did it.

Stock the V8 leaves much to be desired, their popularity is they can be easily modified for much more power/torque.

The pick of the bunch is the 4.2TD HDJ79, much better to drive, better steering and wheel track

Considering the Hyundai / Kia 2.2 puts out almost the same figures as the 4.5L I wonder what would happen if you did blow the V8 and do a swap to the 2.2?

Would it feel the same to drive? Similar performance? Much lower consumption?

The clip covers this in part through bigger engines having more losses through friction of more piston rings on more bores, having more camshafts to turn and valves to operate.

It would be interesting to test in real life rather than hypothetical as a VDJ79 is trying to punch a massive hole in the air at 100km/h.

What people are saying here is correct, with tuning and even turbo upgrades they put out decent power and torque numbers, the question I'm asking is why is Toyota putting this thing to market with such lame figures when its obviously capable of significantly better numbers.

Someone has mentioned that the VDJ79 uses the 6 cylinder gearbox, could it be a driveline problem? One of the first problems you run into with tuning these cruisers with the 4.5L V8 is the clutch, is it just barely adequate for the job or is it designed this way to act like a 'fuse' - rather replace clutch than a gearbox.

Is it a case of the J70 platform was designed in the late 1970s/early 1980s with minor modifications? Maybe if you start putting significantly more power and torque through it, it creates problems? Has anyone driven one of these with say 250KW+ at the wheels?

2007: The facelifted 70 Series began production in January for market release in late February / early March 2007. Changes involve significant modifications to the front end design, eliminating the trademark flat fenders featured on all commercial Land Cruiser series' since the 40 series. This change along with a wider front axle/track and wider chassis were required to allow fitment of the new Euro-4 compliant 4.5L V8 turbo diesel, the 1VD-FTV. This engine was initially just for the Australian market, where it was the only engine available. Africa and other markets continued with straight-6 petrol and 1HZ diesel engines.

Vehicles and Availability
The single-turbo variant of this engine was first used in Australia commencing 2007, fitted to the 70-series Land Cruiser range. The engine is available in Australia, Pakistan,[1] India, Southern Africa, Central and South America.

Though when you put a 200 series up against the last two models of the Nissan Patrol, the VK56 unleaded V8 is getting close to or matching the fuel economy of a 200 series on tow tests.

,........or was that too painful to admit?

On paper yes but i have owned a ranger and now have a LC79
The torque band on the V8 is so much lower down and larger

LC is also almost 5 years old now with nothing but maintenance

Ranger had 2 auto boxes, broken flexplate, multiple lots of seals in the transfer case, 2 cvs, front cover oil leaks, idler pully replaced, split intake pipes etc
at 3.5-4 years old

Yes the LC is less comfortable/fun to drive but its very well made, reliable and an absolute as soon as you leave the bitumen.

That last post is the reason why people buy these LC 70,s.
You cant argue with logic.

Why not? I’ve seen at least 8 2012 diesel Prados with over 500,000kms. The highest kms I have driven was just shy of 560,000kms. They won’t all do it, but they can do it

[cheap]

We have a couple of guys on another forum with TDV8's +500,000k's and one guy at +600,000k's - original engine, gearbox and diffs.

I do roughly 20K per year in my 200, serviced as per the book, purchased new, 3 Simpson Desert crossing, countless corrugated miles and dust, no issues.

Based on my usage it will be another 20 years before I get to 500,000K's. Don't know which will occur first (a) the asteroid hit or (b) me giving way?

Still made for a laugh at all the mis-truths generated by "Auto-Expert" and arm chair experts. Take a TDV8 cruiser out for drive into the outback-outback, you might then get to understand what they're all about.

Ok, so what about the other 99% of driving when everyone isn't in the 'outback-outback'?

There's no doubt that the 70/200 series are very capable vehicles, but given most Ive seen haven't got a scratch on them and they spend all the time driving along Melbourne's freeways then I'm second guessing how good they are for these purposes.

If people actually watched the clip this wasn't our favorite auto expert ragging on the cruiser out of thin air, it was a question from his viewer he took the time to give a very detailed response to.

Okay, I stand (partly) Corrected..
I still think (but Don't know) it'd be easier to Find High Km Cruisers than It would High KM Prado's....

[XR Martin]

There was a Prado getting around with over 1 million kms, read an article about it a few years ago.

Found the car.
Apparently the odo gets stuck at 999999, and must be reset.
Just noticed it's a petrol one. Perhaps the soot chuckers don't last that long.

Unfortunately, I did watch the video and it rambles on and on.

So here is the summary - different engines with different technologies with different capacities, with different gearing ... drumroll these differences result in different efficiencies.

Golly gosh Cordogan is the new Einstien!

Honestly the URJ202 petrol looks fine with its 4.6L V8

https://www.youtube.com/watch?v=vlmq8OIHaRI

Fine for my uses, which isn't much long range touring, pottering around town, occasional deep sand runs and beaches, and the odd needing to start at -10 in the snow.

sounds good too

How are these 4 litre diesel V8s in the new VW Touaregs! :

he new flagship of the second-generation Volkswagen Touareg range launched here a year ago is powered by the same 4.0-litre twin-turbo diesel V8 found in the Bentley Bentayga.

Fitted with two sequential turbochargers, the bent-eight diesel is good for a whopping 310kW of power and 900Nm of torque – 52kW/50Nm up on last decade’s V10-powered Touareg R50.

Its maker says that’s enough to accelerate the Touareg V8 to 100km/h in just 4.9 seconds, almost matching the pace of the much smaller and lighter Golf R hot hatch (4.8sec).

Shame we don't get the 5.7 that the yanks get.

I once drove a friends 8V71 Silver Eagle coach down Woy Woy Rd (NSW) scared the hell out of me, combination of the torque and torsional elastic suspension was interesting empty. Loved it at the end. certainly made a DD convert out of me.
