EcoLife CoachLine for Coaches

A new product family specifically for coaches


Power shiftable

Without tractive force interruption, also on gradients


Low fuel consumption in demanding topography

Primary retarder

High braking force even at low speeds

What can EcoLife CoachLine for Coaches provide?

Hilly roads, narrow curves, high altitudes with reduced engine output, back to intercity or city traffic. Stop and Go. Slow driving. Frequent braking and acceleration. For this mix, ZF has developed the new, independent product family EcoLife CoachLine especially for coaches – for engines between 1,200 and 2,800 Nm.


Powerful and universally applicable

Based on the second generation of EcoLife, CoachLine guarantees high average speed at the lowest engine speeds – now also in top high-performance coaches with up to 2,800 Nm in combination with longer axle ratios.

Without tractive force interruption, and designed for a significantly higher service life, the EcoLife CoachLine shows its advantages over manual and automated manual transmissions.

The engine always brings its full torque to the road – without tractive force interruption and without loss of speed when changing gears. Despite fast acceleration even on uphill gradients, passengers will not notice any gear shifts.

The standard integrated TopoDyn Life driving program makes a major contribution by activating the correct shift strategy to deliver optimum fuel consumption, based on topography and driving resistance. Brake force is adjusted automatically while fuel consumption and noise are kept at a low level.

Since the primary retarder does not depend on the output speed, it delivers maximum deceleration almost until it reaches a standstill. With the CoachLine, downshifting until first gear during retarder operation allows for further fuel savings through the engine fuel cut-off.

The dual cooling system, with the transmission heat exchanger and the increased retarder heat exchanger, enables reliable braking with the retarder even on long downhill gradients and reliably protects against overheating.

The oil quantity, which is nine liters larger than the city bus version, also extends the oil change interval. Depending on the OEM, this can be up to 480,000 kilometers.
