New Mercedes-Benz city bus is equipped with a fully automatic Allison Transmission

Mercedes-Benz and its official dealer COLCAR joined with Allison Transmission to develop a new bus for public passenger transport. The Omnibus OF1621 Euro V is equipped with the fully automatic Allison T270R, which features a retarder to extend brake life.

Allison Automatics are designed to deliver unrivaled reliability and durability while helping to protect vehicle driveline. By engineering and manufacturing reliable, fully automatic transmissions, customers experience a greater overall economic value with reduced downtime and the ability to get more work done.

The Omnibus also features a Mercedes-Benz OM 924 LA front engine with 208 CV of power and torque of 780 Nm, and complies with Euro V pollutant emission standards. Its electronic injection system ensures maximum performance with reduced fuel consumption and high torque at low laps.

Allison transmissions use a torque converter to smoothly multiply engine torque and deliver more power to the wheels. With Continuous Power Technology™, drivers get faster acceleration, greater operational flexibility and increased productivity. This also enables Allison Automatics to outperform manual and automated manual transmissions (AMTs) which lose power and torque with every shift, resulting in wasted fuel and time.

Additionally, Allison Automatics are unique because the torque converter experiences very little wear and the transmissions require only periodic fluid and filter changes to maintain peak performance. Manual transmissions and AMTs both rely on a clutch that eventually burns out and requires more downtime for maintenance. With the Allison T270R, the hydraulic retarder further reduces downtime by increasing the life of the brakes up to four times longer.

Allison transmissions also help fleets expand their driver pool. With today’s drivers being less familiar with driving manual transmissions, Allison fully automatic transmissions are easy to drive. Even experienced drivers benefit from more precise, safer handling and improved comfort. Once behind the wheel, drivers are more alert and in tune with the vehicle, leading to increased driver retention and better safety records.

When factoring life cycle costs – including decreased maintenance and increased productivity – an Allison Automatic-equipped vehicle costs less to operate than a comparable competitively-equipped vehicle.
