Its “free floating” fleet of 290 BMW 1 Series, Mini Countryman and BMW i3 is the largest selection of electric vehicles in London.
Travellers can pick up a car waiting at the terminal in Docklands using the app-based service.
The firm is linked with nine further European airports, including Cologne, Berlin, Munich and Hamburg.
Motorists can leave one DriveNow car in east London and switch directly to another of the service’s fleet after disembarking abroad.
The app will indicate the location of the nearest vehicle.
Driving costs come in at 39p per mile with fuel, parking, insurance and car tax all included.
Managing director of DriveNow believes it offers a “fully flexible solution” for Londoners.
Commercial manager at London City Airport Tom Murphy said: “We pride ourself on offering the best possible experience for customers.
“This new partnership with DriveNow offers more choice for passengers to make their journey as convenient as possible.”
