PACCAR MX-11 Engine and Drivetrain

DAF XF440 features the PACCAR MX-11 10.8L engine constructed from Compacted Graphite Iron (CGI) for increased strength and reduced weight—over 180 kg lighter than the MX-13. The 440 hp variant delivers peak torque from just 900 rpm. Key design elements include a DOHC architecture with four valves per cylinder, hollow camshafts reducing 15 kg of mass, and a Common Rail system operating at up to 2500 bar. The "Pure Excellence" update introduced lighter components, improved turbocharger, lubrication system, and multi-torque logic, providing an extra 100-150 Nm in top gear for enhanced high-load performance.

Transmission and Axle Configurations

The XF440 initially employed ZF AS-Tronic 12- or optional 16-speed automated transmissions; later models feature the ZF TraXon with pneumatic ConAct clutch actuator. TraXon integration with Predictive Cruise Control (PCC) leverages GPS data and road profiling for optimal shifting and fuel efficiency, including EcoRoll mode. Rear axles offer multiple ratio options (2.05–2.53), with the fastest ratio supporting highway speeds at low rpm, reducing fuel consumption and mechanical wear.

Cab Variants and Ergonomics

Available only with Space Cab or Super Space Cab. Super Space Cab provides 2.23 m standing height and 12.6 m³ volume. The lower driver's bed measures 220 cm x 80 cm, with a 15 cm thick mattress and extensive storage (925 L). The Silent package reduces exterior noise to 71 dB, meeting urban restrictions. Low Deck variants—with 91 cm fifth wheel height, unique tire setups, and aerodynamic kits—support Megatrailer operations under European 4.0 m total height limits.

Advanced Safety and Telematics

Advanced assistance systems include ACC, FCW with AEBS, LDWS, and VSC for active lane and stability management. Telematics are managed via PACCAR Connect, integrating Eco SCORE analytics, Remote Tacho Download, and 10-year OTA support. Retardation is handled by a 320–340 kW MX Engine Brake or optional ZF Intarder, the latter providing up to 500 kW braking force for mountain routes.
