The Paccar MX-13 engine is gaining acceptance among Kenworth Class 8 customers, the company says.
KIRKLAND, Wash. — Kenworth says the popularity of its Paccar MX-13 engine is growing amongst Class 8 truck customers.
The company this year increased its rating to 500 hp and 1,850 lb.-ft. of torque.
“Kenworth customers continue to choose the fuel-efficient and reliable, proprietary Paccar MX-13 engine at a growing rate for their Kenworth Class 8 truck purchases,” said Preston Feight, Kenworth assistant general manager for sales and marketing. “Customers appreciate the engine’s fuel efficiency, higher horsepower and torque ratings, excellent reliability, and quiet operation.”
Paccar says its MX-13 engine is designed for a B10 life, meaning 90% of the engines will reach a million miles without a rebuild. Earlier this year, the company tore apart a couple of the earliest MX-13 engines to be built. At about 550,000 miles, they showed wear patterns comparable to a newly broken-in engine, Paccar claims.
