For more and more consumers, the decision to buy a new car quickly becomes a choice to buy some kind of sport utility vehicle. Automakers are rushing to feed that demand, especially given signs that industrywide U.S. sales are peaking.

At this year's Los Angeles Auto Show, Alfa Romeo revealed its first-ever SUV, the sleek Stelvio, while Jaguar introduced an electric I-Pace concept. Mini pumped up its Countryman crossover, while Ford is bringing its EcoSport to the United States. Mazda has a new CX-5, and Volkswagen showed the seven-seat Atlas, conceived to woo American shoppers.

The onslaught of SUVs - typically big profit generators - should help insulate the automakers from next year's predicted decline in U.S. vehicle sales. Light trucks, which include SUVs, pickups, and vans, climbed to 59 percent of U.S. sales this year through October from 55 percent a year earlier, according to the researcher Autodata Corp. In an era of low fuel prices, much of the gain has been from new SUV models, and the shift shows no sign of ending.

SUVs are the overwhelming choice when consumers switch from one class of vehicle to another, including almost a third of everyone who trades in a car, according to The trade-off suits both sides: Consumers get more storage and a more elevated view, while automakers earn more profit from SUVs than from sedans.

And once consumers buy an SUV, they tend to buy another. This year, 72 percent of people trading in a sport utility decided to stick with that vehicle class - considerably higher than car loyalty at 62 percent and very close to pickup loyalty at 74 percent, said senior analyst Jeremy Acevedo.

SUVs are making their popularity felt even in Los Angeles, as California pushes ahead with its U.S.-leading crackdown on fuel efficiency in part because of the proliferation of SUVs and pickups. Automakers already are responding with battery-powered SUVs such as Tesla's Model X, which debuted in September 2015, and Jaguar's I-Pace, slated for production in 2018.

Broadly defined, sport utilities and crossovers have outsold all sedans since the second half of 2014, said Tom Libby, an analyst at IHS Markit.

SUVs are "taking share from every body type except pickups," Libby said. Pickups are basically holding steady because they are more rugged and have unique capabilities that make them suitable for work. Mini's redesigned Countryman SUV - 8 inches longer than its previous iteration - has a navigation and entertainment system adapted from BMW's 7 Series, restyled to fit the smaller brand's image. The biggest Mini will also be available as a plug-in hybrid by mid-2017. With all-wheel drive, British styling, and go-kart handling, it provides a unique take on the popular segment, said Ralph Mahler, the brand's vice president for product management.

The Countryman has "all-day functionality," Mahler said. "I think that's the combination of why the segment is also growing and why we have so many customers going for SUVs."

Though SUVs may seem typically American, their popularity is global and they are gaining share across Europe and China. By the end of this year, SUVs and crossovers will probably catch up with cars worldwide, said Finbar McFall, Jaguar Land Rover's head of product marketing. The company's Jaguar I-Pace is the brand's first electric model and second SUV.
