Kenworth says production will begin in the fourth quarter of this year. 

The Paccar MX-13 CARB-compliant engine features new aftertreatment hardware to meet California's low nitrogen oxide (NOx) emissions requirements. It has a twin-canister selective catalytic reduction aftertreatment along with more optimized emissions controls systems. 

It's available in two options, one with a 510-horsepower rating with 1,850 lb.-ft. of torque and a 455-horsepower rating with 1,650 lb.-ft. of torque. 

Last week, Peterbilt announced the same engine is available for order in Models 579, 567 and 589.
