xFE

 

xFE is another in a string of innovative, fuel saving ideas from Allison. xFE stands for Extra Fuel Economy. This fuel savings results from new gear ratios designed to squeeze more value from every tank of fuel.

 

Earlier Lock Up + Lower Engine Speeds = Extra Fuel Economy

 

xFE models have been designed to deliver significantly more torque converter lock up operation and spend more time in higher ranges at lower engine speeds producing exceptional fuel savings.

Faster Lock Up For Increased Efficiency

 

We’ve designed our transmission models with xFE to lock up at lower speeds, specifically for the constant shifting and lower average speeds of fleets. This means lock up happens significantly earlier and vehicles run longer where they are most efficient.

xFE + FuelSense® 2.0

 

Mediante un insieme di perfezionamenti apportati al software proprietario, FuelSense® 2.0 fornisce combinazioni infinitamente variabili di punti di cambio marcia. Piuttosto che affidarsi a rapporti fissi predeterminati, FuelSense® 2.0 utilizza un algoritmo intelligente che individua continuamente l’equilibrio tra economia dei consumi e prestazioni più adatto al vostro ciclo di lavoro, facendo in modo che il vostro veicolo operi in maniera più efficiente.

 

Per Saperne Di Più

 

Designed for Both Fleet and OEM Convenience

 

City and transit buses, distribution trucks, refuse vehicles and pupil transport buses are ideal applications for xFE technology. The start-stop dense routes and lower average speed duty cycles present special challenges for any transmission. Allison fully automatic transmissions with xFE meet these challenges without sacrificing drivability or performance and are compatible with alternative fuel engines. Best of all, installation of an xFE transmission is the same as a standard Allison model.
