The Pacifica is a bit lower, a bit wider, and a bit longer than the SRX. It's practically identical in weight. It's also k cheaper than the SRX. SRX is either RWD or AWD in both V6 and available V8 (with 320 Hp). Chrysler had a vision of a primo hybrid between a station-wagon and suv. Looks like Cadillac built it.
