The programme launched in San Antonio in March, and its success has made the city the second in Texas to have an electric vehicle on its fleet. Hertz on Demand is a pay-as-you-go service with no annual fees and permanent access to vehicles with no late fees. Cars can be reserved online by any of its 150,000 members.

Mark P. Frissora, chairman and chief executive officer of Hertz, said: ‘We've enjoyed a successful partnership with the City of San Antonio, seeing membership and usage continue to grow each month, and we're pleased to expand Hertz On Demand to make it even more convenient and accessible to residents, visitors and workers throughout the city.

‘Hertz is bringing the future of mobility to city residents with the addition of the Nissan Leaf Electric Vehicle while expanding our overall fleet to more than 20 vehicles and tripling the number of car sharing locations, allowing members to easily select the car they want and go.’
