The 1990s began the decade in a recession, which resulted in weak auto sales and operating losses. In addition, the Invasion of Kuwait by Iraq caused a temporary jump in oil prices. However, the automakers recovered fairly quickly. In the mid-1990s, light truck sales (which included Sport utility vehicles, Pickup trucks and Minivans) began to rise sharply. Due to the Corporate Average Fuel Economy standards differentiating between passenger cars and light trucks, the automakers were able to sell large and heavy vehicles without fear of the CAFE fines. Low oil prices also gave incentives for consumers to buy these gas-guzzling vehicles. The American automakers sold combined, and even separately, millions of pickup trucks and body-on-frame SUVs during this period. Imports such as the Toyota 4Runner, Land Cruiser, Tacoma, and Nissan Pathfinder and Frontier were also popular during this time period.
