Peterbilt Motors Company recently announced updated offerings for the 2019 PACCAR engines.
Peterbilt will offer the MX-13 with two new ratings for the 2019 model year engines: a multi-torque 455 horsepower with a torque rating of 1,650 to 1,850 pound-feet, and a 405 HP with 1,650 lb.-ft. of torque.
Each update for model year 2019 engines was designed to increase reliability and fuel economy.
When packaged with the PACCAR transmission and the PACCAR 40k rear axle, the new 405 HP and 1,650 lb.-ft. torque rating for the MX-13 provides one of most fuel efficient integrated powertrains for long-haul customers, Peterbilt said.
“Peterbilt and PACCAR Powertrain work closely to ensure Peterbilt customers have the most fuel-efficient options available, and they already benefit from a total weight savings of more than 500 pounds when spec’ing the full PACCAR Powertrain on the Model 579,” said Wesley Slavin, Peterbilt’s on-highway marketing manager.
“Peterbilt’s customers have challenged us to find even more ways to maximize fuel economy and these new ratings deliver.”
The new engine ratings will be available January 2019, the company said.
