New GO 250-8 PowerShift transmission

Together with the Euro VI engines, Mercedes-Benz is introducing the new eight-speed GO 250-8 PowerShift bus transmission in the Travego Edition 1. This fully automated transmission is based on the highly popular GO 240-8 PowerShift transmission still in use in other models.

Drivers benefit from the familiar, progressive ratio graduation, together with fast and comfortable gearshifts. The ratio spread likewise ranges from 6.57 in first gear to 0.63 in top gear.

The designation of this transmission indicates that it is approved for a maximum engine torque of 2 500 Nm. A heat exchanger now keeps the oil temperature in the transmission at a constant operating level of around 80 degrees Celsius. This has a positive effect on oil change intervals.


Practical crawler mode and a new retarder

The vehicle also features a new crawler mode which works in the same way as on automatic transmissions. It allows for precise manoeuvring by only using the brake pedal.

The new, integrated retarder achieves a braking torque of up to 3 500 Nm. It is designed as a secondary retarder and uses the engine coolant for braking and cooling. This eliminates the previous oil/water heat exchanger and the associated oil changes for the retarder. Despite the improved performance, this measure has reduced the dry weight of the new GO 250-8 by 20 kg to 285 kg compared to the previous transmission.

The practically wear and maintenance-free clutch is also new. Thanks to a centrically located, pneumatically operated clutch cylinder it dispenses with mechanical parts such as a release fork, release bearing and servo assistance.
