Your are partially correct my 2010 Legacy is a EJ25 (Phase II engines 1999 up) but there is a FA25 engine designation
Nope, I'm 100% fully correct. While there is an FA20, an FA20F and FA20D, there is no such thing as an FA2
5.
You'll notice that the BR-Z and FR-S use the FA20, the Forester XT and the new WRX use the FA20F (tuned slightly differently). Still no 2.5L FA motor. There is the F
B2
5, which is not the same as the FA, though similar.
I am actually waiting for Chrysler to announce their new minivan in hybrid form. The Fiat guy said a couple of years ago that they were working on one.
Not that I would buy one from Chrysler, but I believe that move on their part would force Toyota to move their *** out of the comfort zone and incorporate their hybrid powertrain into the Sienna. Possibly in a brand new and more fuel efficient new Sienna. Hopefully Honda follows suit, to give Toyota some competition and not end up like the Highlander Hybrid, that costs 6 grands more over the regular Highlander...
A hybrid minivan in 4, 5 years from now would make me seriously consider getting one.
Don't hold your breath. It's not because they don't think that they could get better fuel economy, nor that they don't have a hybrid system that they could use, but the battery has to go somewhere. It's kind of like the Sienna AWD - in order for the rear driveshaft to fit, there could not be a spare tire and all Sienna AWDs come OEM with runflats for that reason. Many folks already say "I won't buy the AWD Sienna because then I have to use runflats or take up cargo space with a spare tire!"
If they did make a Sienna hybrid, it could be AWD like the RX hybrid is, but it will then lose the rear seats' ability to be folded flat into the floor. Most folks would rather have the folding seats than save 2-3L/100km, and pay $3,000+ for the premium of having the hybrid system.
While I am fully in support of an AWD minivan, I have less support for a hybrid minivan. I would like to see a minivan be more fuel efficient, but the reality is that there's simply no great place to store the battery. I'm amazed that our RX400h has a full-sized spare tire and a massive battery pack, but that's because the battery sits under the rear seats. In a minivan, that's simply not possible, especially if you want the seats to be removable.
