JULY SALES: U.S. auto sales rose just 1 percent in July due to worries about the economy and continuing shortages of Japanese vehicles.

WINNERS AND LOSERS: New small cars like the Kia Optima and Chevrolet Cruze saw strong sales. So did fuel-efficient SUVs like the GMC Terrain, Ford Escape and Jeep Grand Cherokee. The Toyota Camry regained its spot as the top-selling car in the U.S., but sales of most Toyota and Honda vehicles fell sharply.

WHAT'S NEXT: Automakers must wait and see if sales rise after Japanese supplies are replenished or if demand remains soft because of the economy.
