🔧 PACCAR MX-13 Engine
PACCAR's MX-13 is the proprietary 12.9-litre inline-six diesel used in Kenworth and Peterbilt (both PACCAR brands) as well as DAF Trucks in Europe. The same engine is sold under the DAF and PACCAR names in different markets — a rare example of a truck manufacturer designing its own powertrain and deploying it across multiple brands on separate continents.
