Peterbilt Motors Company announced a new optimized drivetrain package
for its already fuel-efficient leader, the aerodynamic Model 579, that
brings even greater levels of fuel economy, the company announced during
the Mid-America Trucking Show.
Called APEX, the new spec option pairs the PACCAR MX-13 Engine with the
Fuller Advantage Automated Transmission. The combination features
optimized shift calibration, weight savings and proprietary control
logic between the two components.
“This is a winning combination for our customers looking to get even
more miles per gallon from their already fuel efficient Model 579,” said
Darrin Siver, Peterbilt General Manager and PACCAR Vice President. “It
assists drivers with error-free shifting that means even a fleets’
novice drivers can operate with the fuel efficiency of more expert
drivers.”
APEX is available now available for order through the Peterbilt dealer
network.
According to Peterbilt Chief Engineer Landon Sproull, APEX can result in
up to a 4 percent improvement in fuel efficiency versus previous
drivetrains. Superior fuel economy is achieved, he said, through the
precise fuel management resulting from proprietary communication
technology.
“APEX results in exceptional performance and fuel economy by pairing two
already fuel efficient components together and optimizing the way they
communicate to reach even greater levels of savings,” said Sproull.
“This is a fully integrated powertrain that is packaged in our flagship
Model 579, which is already exceeding customer expectations for fuel
efficiency.”
The 12.9 liter PACCAR MX-13 Engine and the 13-speed Fuller Advantage
share critical data including torque, operating gear and other vehicle
performance metrics.
Additionally, Sproull said, APEX is more than 80 pounds lighter than
previous combinations and features a small-step ratio in 9th
and 10th gears for a more fuel efficient operating range
while downshifting.
The PACCAR MX-13 Engine is available with 380 to 500 horsepower and up
to 1,850 ft-lb of torque.
