What is the maximum cargo capacity of 2008 Chevrolet Impala?

The 2008 Chevrolet Impala doesn't have a single, universally stated "cargo capacity" number because it varies slightly depending on the trim level and whether the rear seats are folded down. However, you'll generally find it listed around 18.8 cubic feet with the rear seats up. Folding the rear seats down will significantly increase cargo space, but a precise figure isn't typically published.
