PARK RIDGE, NJ – In an apparent race to be seen as the greenest company in the industry, car rental giants Hertz and Avis are adding thousands of new, fuel-efficient hybrid cars to their fleets this month, according to USA Today.

Hertz announced on June 14 it is putting 1,000 Toyota Prius gas-electric hybrids into its U.S. fleet this month. They will be available at 50 big airport locations and in Manhattan. The company expects to have nearly 2,000 hybrids in its 410,000-vehicle U.S. and European fleet by the end of this year and 4,300 by the middle of next year.

Asked about its plans, Avis will introduce 1,000 Priuses into its fleet by the end of this month. The Avis hybrids will primarily be available in California, with some in the Washington, D.C. area, Seattle and Portland, Ore. Hertz and Avis guarantee hybrid reservations, according to USA Today.

The moves follow an announcement a week earlier by Enterprise Rent-A-Car, highlighting what the company called its “unparalleled fleet of fuel-efficient vehicles,” which includes 3,000 gas-electric hybrids in the United States.
