🔧 PACCAR MX-13 Diesel Engine
The PACCAR MX-13 is a 12.9-litre inline-six developed exclusively for PACCAR's two premium truck brands — DAF in Europe and Kenworth/Peterbilt in North America. Because PACCAR owns both the DAF factory in Eindhoven and the Kenworth/Peterbilt plants in North America, the same engine family serves premium trucks on both continents under different badges. The XDi (Extreme Diesel) injection variant achieves 510 hp with 2,650 Nm, and the EPA-certified North American version produces 490 hp.
