The Pacifica is a minivan. :p According to the automotive press anyway. The EPA classifies it as a light truck.
It is an interesting concept, but really nothing that isn't on the market already. I'm kinda disapointed that it is using Chrysler's existing 4 speed automatic and not a 5 auto from the Mercedes or ZF parts bin.
Now, as for being $6,000-$9,000 cheaper, that is not really acurate. The FWD Pacifica comes in at around $32,000 and the AWD comes in around $34,000.
You can get a Lexus RX330 for around $35k.
You can get an Acura MDX for around $35k.
You can get a Volvo XC90 for $33k.
The list goes on and on.
It will be interesting to see how well the model fairs in the marketplace after the initial "Gee Whiz, something new." rush dies off.
