Two of the new luxury suv models have seating for 8 people. Namely, the 2011 Ford Expedition and the 2011 Cadillac Escalade Hybrid. Both of these have plenty of room for an extended family, but for interior comfort and extra leg room. Even though it only seats 7, the Cadillac Escalade ESV, has to take pride of place. It is a whopping 221.4 inches in length. This extra length means extra leg room for both driver and passengers. Along with the other Cadillac, it has a removable third row of seating. The Ford has long leg room and a split bench seating arrangement for the third row of seating. The Ford is the most affordable of all.
