Just like the Tahoe, the new Suburban is going to be significantly larger than last year's model.
From
Chevrolet:
As the longest-running nameplate in automotive history at 85 years, Suburban established the segment and remains a trusted partner for customers who need maximum space. With a 4.1-inch (105 mm) increase in the wheelbase and a lower cargo floor, the new Suburban has the most passenger and cargo space of any SUV. Legroom increases for both the second- and third-row passengers, and maximum cargo volume expands 19 percent while Suburban’s overall length increases less than 1 percent.
