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.

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....?
