If Toyota wants to make a splash,
then a new bigger engine in the 5.9 liter class would be something to consider. Each of the Big 3 will make similar engines but will not make the same size engine so that each can brag that they have the best/most powerful engine in their class: GM used to make the 5.7, Ford had their 5.8, Dodge had the 5.9. GM don't make the 5.7 anymore, going to the 5.3 so Dodge got the go ahead to call theirs the Hemi 5.7, etc.
Nissan calls theirs the 5.6 Endurance. That means Toyota has to find an "unoccupied" size.....alreayd taken is the 5.6, .7, .8, .9, and the 6.0. Calling it the 5.5 does not make much sense since you need to make a good size jump away from the 4.7.....go to the 6.1?
Go to the 5.9 makes some sense since Dodge ceased using the 5.9 gas--since going to the 5.7 Hemi, but still has the 5.9 Cummins diesel....
That's it! 5.9 liters. 350 horses. 450 pounds of torque. Great engien for the big brute Landcruiser, enough for Toy to make a real 1/2 truck in their new plant, or going ot a larger Tundra with a real truck engine.....
But Toyota has been and is known for being conservative.....how else to explain the largest sub 5 lliter engine compared to BMW, Range Rover, and Mercedes and the lowest horsepower?
It would be nice, and if it comes in the next 5-6 years, that would be just the time I can trade in for a new updated and redesinged and up-powered Landcruiser......bu I wouldn't hold my breath....
