Another factor driving demand for large SUVs is the fact gas prices have been in check this year, and even started dropping over the last couple of months.
AAA said the average price for a gallon of gas in the U.S. is now $3.07, with 17 states selling gas for less than $3 a gallon.

"As the cost of gas has dropped, so has the cost of ownership," Dominique said. "When people spend less on gas, the lifestyle component comes into play. They're willing to pay to get the vehicle they want."
In addition, large SUVs have become more fuel-efficient. Take the four-wheel drive 2015 Chevy Tahoe, for example. Its fuel-economy rating says the SUV will deliver 16 miles per gallon in the city and 22 miles per gallon on the highway. While it's certainly not blockbuster mileage compared with a midsize car or gas electric hybrid sedan, it's an improvement from the 2008 model's 14 mpg in the city and 19 mpg on the highway.

"There will always be a segment of the population that wants a large SUV. For those people, the mileage on the new full-size SUVs is improving and that makes the models more attractive," Dominique said.
