You. Personally.

That sums it up.

The torque curve is the beauty of the 4.5D (479@ 1,600 rpm) over the 5.7 (403@ 3,600 rpm). The utility is what an SUV is all about and towing capacity of the diesel is increased 716 lbs over the 5.7 gas. Further, you being a CT driver (if that's what the "CT" means) maybe you can respect the 24 city/ 31hwy/ 27.7 combined mpg numbers. Now that we got that out of the way, what is it that makes the additional 115 horses in the 5.7 more attractive? Because with 5 people (1000 lbs), luggage (600 lbs), and a 6,000 lbs camper, the 5.7 will be a bit too small for the job.

No, you are incorrect. The Land Cruiser 5.7 has a higher tow rating than the Land Cruiser 4.5.

And load up both, the 5.7 will out haul the 4.5, you keep neglecting the fact that the 5.7 has 403 ft lbs at 3400rpm. Add in 383 hp and it is a far superior engine. The 4.5 while nice, it really is a Substitute for the 4.6 petrol land cruiser. Add in at least a $6k-$8k price increase over the 5.7 and you can clearly see why the 4.5 would never fly in the USA.

And uploaded, the 5.7 is a far better engine than the 4.5.

A Nissan Titan Cummings would be a good argument for an alternative over the 5.7.

Sorry but that's not how things work. Case in point -- you can gear a bicycle to have 1000 lb·ft of torque does it make it a superior towing machine? ;-)

In order to tow an engine needs to perform a certain amount of work. This amount of work is measured in HP. An engine with a bigger HP will always be able to tow more than an engine with lower HP simply because it's able to do more work. This is simple mathematics -- HP = TORQUE x RPM.Yes the 5.7 gasser has less torque but it's able to compensate for it by having more RPM and thus archive a greater HP number.

Those here advocating the 5.7 over the 4.5 Diesel....

When's the last time either of you actually drove one, or ANY Diesel for that matter?

This information is available on the net. The LX450d is not a substitute for the old gas motors. The LX450D is priced less than the LX570. The LX450D tows more than the LX570. LX450D uses a 6 speed transmission and the LX570 uses the 8 speed. The 450D tows 7,716 lbs * and the 570 tows 7000 lbs. Every statement is not opinion. These statements are the facts from the two sites listed below. We should get to the facts about cars instead of the feelings or perception.

Has anyone considered fuel mileage *while* towing?

Certainly the diesel will stomp all over the gasser in this case.

So I saw this thread yesterday, and incidentally I was driving my diesel truck last nite. I went to a gas station to fuel it up yesterday and snapped these pictures. The pump on the left is for petrol and the one on the right is for diesel. See how filthy the area around the diesel pump is? I promise it was an absolutely random gas station that sells diesel, I did not specifically pick it out. You will notice the same at pretty much every gas station that sells diesel. The problem is that diesel fuel is a stinky oily substance, and all the little spills never dry out. You get this stuff on your hands and shoes and then you transfer it to your car carpets and steering wheel. I carry a pair of rubber gloves in my truck so I don't get diesel on my hands, because the pump handle is always filthy. Just for that reason alone I would never ever get a passenger diesel car, never mind a luxury diesel car.

A minor inconvenience to a superior fuel.

Unless you missed I never disputed diesel advantage in MPG while towing over gasser.

Default Valid Point, but there is a solution on the horizon...

Valid Point, but there is a solution on the horizon...It won't be long before you pull up to a gas station, pay via wifi or bluetooth and get back on the road.

Toyota has some of the finest diesels in the world. It would be interesting to see if the USA gets introduced to them. Someone mentioned dreams earlier...the hybrid diesel SUV is the stuff dreams are made of: http://www.hino.com/hino-trucks-hino-195h.html

A diesel hybrid will never happenin USA.

1st there is a premium for diesel tech
2nd there is a premium for hybrid tech

Makes no sense.

We are in the USA, there is a premium for any service (if that's what you mean). In Russia the 450d sells for less than the 570, so not sure where your statement is headed. Toyota offers 150,000+ mile warranties on it's diesels. Once upon a time Submarines were diesel electric (and some are now). Can you fathom taking a 1,000 mile trip and paying less than $65 to do it? Take a look at these beauties from MB:
