If I am reading the WSJ article right, no Li-Ion before 2011 and maybe not then. Any new Hybrids are on hold till they can find a battery to replace the NiMH currently being used.

I wouldn't call any Hybrids that does 50k a year a flop.
Civic Hybrid does about that, maybe less. I wouldn't consider that a flop.
They were speaking relative to the Prius, which is a huge success. These are in relative terms.
Is David Wright a flop compared to Alex Rodriquez?

Interesting how nobody has tried that yet....a hybrid minivan. Ford did a great job on the Escape Hybrid - you can hardly tell the batteries are even in there, the spare is still underneath, and you still have a decent floor in the back too. I would think the Sienna could be made to work with the Hybrid.....maybe engine bay space is a problem?

Toyota has the "Estima" hybrid minivan in Japan, and has had it for several years.
Click here for more info on the Estima
I cannot for the life of me understand their reticence to do it as a Sienna in the USA.
Confusing as heck !!!

If you stick the 2.4 hsd in sienna, you get your estima. minivans w/o v6 don't sell in the US, unfortunately. Looking at the link, it seems the hybrid will improve the mpg by about 25% over the 3.5l. I think they will bring it out if the next gen ody comes with a diesel option.
#35 of 35 What about....

A Sienna hybrid with the I4 but with a Miller Cycle using a positive displacement variable speed Supercharger. Use an E-CVT with a engine drive belt into one end and a permanent magnet AC synchronous motor at the opposite, ~3:1 reduction, end.
A variable frequency drive to the AC motor would allow complete, full range, engine throttling without a throttle butterfly valve. No boost would be provided unless extraordinary level of power were asked for.
Note that the 2.3L Twin-turbo engine in the Acura RDX produces 240HP. In comparison a hybrid Miller Cycle 2.3L I4 SC'ed as above (NO Turbo LAG) would only need to produce about 200HP w/full boost in order to match the performance of the RX400h.
A 40MPG Sienna....?
