The ESV's extended dimensions don't yield significant gains for first- or second-row occupants, but third-row passengers gain nearly 10 inches of legroom. Cargo volume behind the third row increases from 16.9 cubic feet to 45.8 cubic feet. With the third-row seat removed and the second-row seats folded forward, maximum cargo volume is 137.4 cubic feet — about 28 cubic feet more than the standard Escalade offers.

In the Escalade ESV, the optional DVD entertainment system includes a second 8-inch screen for third-row passengers. A leather interior, automatic climate control and power-operated front seats are standard. Total seating capacity is seven, though an optional second-row bench expands capacity to eight.
