The Hertz Corporation is developing compressed natural gas (CNG) vehicles in the US. Hertz will begin renting CNG Honda Civics and CNG GMC Yukons at Will Rogers World Airport in Oklahoma City early next month. All vehicles will include NeverLost GPS units to assist renters in mapping local CNG refueling stations. Oklahoma City is serving as a pilot program for Hertz’s CNG airport rentals program. In addition to having significant CNG fueling infrastructure across the state -- approximately 70 existing or planned public stations -- Oklahoma is also home to several of the top natural gas producers in the country, including Chesapeake Energy Corporation. The expansion of energy-efficient and clean vehicles stems from the launch of Living Journey, Hertz’s global sustainability strategy announced earlier this year.
