Scania makes fuel reduction a top priority.

Scania Reducing Truck Fuel Consumption & Brake Maintenance with New Retarder

Scania says its freewheeling retarder gives customers a smooth, powerful ride while still keeping comfort a top priority.

According to Orjan Aslund, who is responsible for product affairs at Scania Trucks, one of Scania’s main priorities is working to reduce fuel consumption. Now, one of the Scania Retarder models is available in a new version, and this truck does reduce fuel consumption while still providing a comfortable drive.

Many trucks have some form of auxiliary brakes. For almost two decades Scania’s customers have been able to appreciate just how powerful, yet smooth, effect a hydraulic retarder from Scania can provide. Besides comfort and a relaxing drive, it also provides savings by reducing the need for normal brake system maintenance. In this latest version, the retarder automatically disengages and freewheels when not in use to save on fuel. And it is now even more powerful than before. “The freewheeling retarder produces further savings that also contributes to an elevated driving experience,” explained Aslund.

One of the Scania Retarder models is now available in a new version (R4100D) that automatically disengages and enters a freewheeling mode when not active. This reduces drag losses because both vaned wheels that provide braking power when rotating in oil are disengaged. Actual fuel savings will vary depending on road conditions, but an average of a half percent reduction is taken as the rule of thumb.
