First off, I am far from being up to date or knowledgeable on this topic like all of you guys, so please correct me where I am wrong.
So, what I gather is that (based on the list of manufacturers mentioned earlier) the majority offering extensive diesel options in their US lineup are European brands? Now aren't the Europeans generally much more into consumer diesel vehicles versus the US? Which would mean that these brands can possibly bring diesel technology to the US at a much lower cost than say...Toyota?
Now turning to Toyota's current line up, I think it would be fair to say that they are pretty decent at hybrid technology?
Which leads me to my point...if one argues the CAFE position, wouldn't it make more financial sense that Toyota pursue a hybrid option as opposed to a diesel option?
After all, Toyota is here to first make a profit, and then appease to the masses if/when they can. So, I am going to go out on a limp here and say that I doubt Toyota really cares about a bunch of 4runner enthusiasts
I do understand that other manufacturers are now trying to introduce diesel into their line up as well, but they also probably don't have a successful hybrid technology going for them currently. Thus, from a cost stand point, it really wouldn't matter if they now invest in diesel or any other alternatives. But for Toyota, hybrid seems to be the obvious choice over diesel (at least for most of their consumer grade lineup).
4Run4Yourlife pointed out the 3.0 Turbo Diesel used in the Toyota Prado. Toyota uses diesel in the global market just not here in North America. So the idea that it would be more cost prohibitive for Toyota to provide a diesel than any other brand doesn't seem tangible.
I will take the opposite position of 1Engineer on the subject of Hyrbids but I will try to provide some reasons for my position. I think a Hybrid can make sense for a small car like the Prius because the mpg are very high. If purchased new the battery has a warranty that usually will outlast the first owners time with the vehicle, but they do eventually wear out and when they need to be replaced it's a huge bill. Hybrid's at this point and time don't have the longevity that a diesel engine would provide. The next is performance of the Hyrbid powertrain in a heavy vehicle, the Highlander Hybrid weighs 3,946 and manages mpg estimates of 28/28 what would the numbers be with the additional weight of the 4Runner and worse aerodynamics? The SR5 4x4 weighs 4,675 and the Limited 4x4 weighs4,805 without passengers or payload.
So you end up with a vehicle that would have a similar cost due to the Hybrid drive, likely not perform as well in most driving situations, wouldn't even match the diesel mpg's, and if kept long enough to justify the Hybrid would not have as good resale as people wouldn't be wanting to replace the battery shortly after purchase. These are some of the reasons Hybrid doesn't make sense to me in a mid to fullsize SUV.
