Multi-Torque Ratings
OEM
Description:
Multi-Torque is an optional engine rating that provides
two different torque or power curves for a single rating.
The engine operates on the “standard torque” curve in
the lower gears and on the “multi-torque” curve in the
top 4 gears. The number of gears in which multi-torque
is operational depends on the drivetrain component
specifi cation. Either 100 or 200 lb-ft of additional torque,
depending upon the rating, is typical at peak torque
when operating in the “multi-torque” mode.

Multi-Torque
Standard Torque
The ECM determines when the vehicle is in the top
gears by calculating the ratio of engine speed to vehicle
speed. The number of affected gears is determined by
the selected Multi-Torque Rating feature.
Available:
C-10, C-12, C-15, C-16, C11, C13, C15 heavy duty engines
Advantages:
With the additional torque the truck can crest the hill
without shifting. This can increase fuel effi ciency,
reduce wear and increase driver satisfaction.
