Austin, TX – Peterbilt Motors Company announced updated offerings for the 2019 PACCAR Engines at the ATA Annual Meeting on Oct. 28.

Peterbilt will offer the MX-13 with two new ratings for the 2019 model year engines; a multi-torque 455 HP with a torque rating of 1,650 – 1,850 lb.-ft. and a 405 HP with 1,650 lb.-ft. of torque. Each update for model year 2019 engines was specifically designed to result in increased 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, the company says.

“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 lbs. when spec’ing the full PACCAR Powertrain on the Model 579,” said Peterbilt’s on-highway marketing manager Wesley Slavin. “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.
