Why SUVs are getting bigger and bigger: GM, Toyota, Ford enlarge hefty vehicles

Just when you thought sport-utility vehicles couldn’t get any bigger, they are.

Two of the auto industry’s most hulking SUVs, the Chevrolet Tahoe and Chevrolet Suburban, are growing in size for the 2021 model year.

For customers, that means more headroom, more legroom and more space to haul stuff.

For automakers, that means more profits because large SUVs are among the industry’s biggest moneymakers, rivaled only by full-size pickups, which are also getting bigger.
