The ZF EcoLife is an automatic transmission designed to handle the high torque outputs of newer city buses. The EcoLife was launched in anticipation of Euro 6 and EPA 2010 emission standards in Europe and North America, respectively. The EcoLife boasts lower operational costs as well as reduced drive noise with a new integrated torsional damper and helical gearing. With few filters and lower oil consumption, oil change intervals are increased. The EcoLife also manages drive programs in real time unlike the Ecomat Series which use a pre-determined drive program.
The TopoDyn program helps regulate normal or power drive programs more intelligently. TopoDyn selects the best shift points based on the gradient, thus maximizing fuel savings. On starting, the TopoDyn program selects the "Eco" mode. For inclines, it selects "Normal" mode. For strong inclines or declines, "Power" mode is selected.
In 2016, ZF introduced a start/stop feature. This automatically shuts off the engine when the bus comes to a standstill. As the driver moves their foot from the brake pedal to the accelerator pedal, the engine and the transmission are able to immediately start. This function allows for a decrease in fuel usage.
