The PACCAR MX-13 engine features a new torque curve that further refines the engine’s fuel economy performance in line-haul and regional haul applications by lowering the engine’s horsepower rating while maintaining its torque.
“This combination maximizes fuel economy and offers excellent performance for our customers,” said Kurt Swihart, Kenworth marketing director. “One of the bigger contributors is the deeply integrated predictive cruise control function, which varies the vehicle’s speed over rolling hills without reducing the average vehicle speed. The transmission software is also optimized for the PACCAR MX-13, allowing for lower engine RPMs at cruising speeds. At Kenworth, we’re continually researching ways to enhance spec’ing to find the best fuel economy combination available. The new 405-horsepower rating is just one example.”
The PACCAR Powertrain Fuel Economy package will be available in the first quarter of 2019.
