Scania S520 Used Trucks - Current Offers for Sale

Powertrain and Driveline

The Scania S520 is powered by the DC16 16.4L V8 turbo-diesel, delivering 520 hp at 1,900 rpm and 2,700 Nm of torque across 1,000–1,300 rpm. The engine features individual four-valve heads, XPI common-rail injection up to 2,400 bar, and a "low-rev" torque band, which supports efficient high-gear cruising. Later S520 units use SCR-only aftertreatment, reducing complexity and enhancing fuel efficiency. The S520 utilizes Scania’s Opticruise automated manual transmission (GRS905/GRSO905), equipped with a lay-shaft brake for rapid, uninterrupted shifting, plus two low crawler gears. The R4100D retarder, with a mechanical disengage clutch, delivers up to 4,100 Nm auxiliary braking with reduced drag for fuel savings. Rear axle options include single reduction (e.g., R780, R756) for standard haulage, and tandem hub reduction axles rated for GCMs up to 210 tonnes for specialist applications.

Cab, Ergonomics, and Aerodynamics

The S520 is exclusively paired with the S-series flat-floor cab (CS20), available in Normal (1.85m internal height) and Highline (2.07m) variants. Internal cab length is 2,060mm, with extendable lower bunks up to 1,000mm wide, optional upper bunk, and multiple mattress choices. Exterior surfaces are optimized to reduce drag (up to -18% Cd vs previous gen), with precise panel fit and available aerodynamic kits. The cab structure enables the installation of low-profile, high-capacity parking coolers (e.g., Bycool SLIM) without breaching the EU maximum height limit.

Chassis and Bodybuilder Adaptability

The modular chassis supports various frame thicknesses up to F950 (270x90x9.5mm, >700 N/mm² tensile strength), optional double frames for heavy haulage, and flexible wheelbase/fuel tank layouts (up to 910L diesel, 123L AdBlue with D-shaped tanks). The pre-drilled 50mm grid enables fast bodywork installation without structural compromise. Electrical and pneumatic prep, plus the programmable BCI CAN-bus interface, streamline external equipment integration.

Driver Assistance and Digital Systems

The S520 integrates advanced ADAS supporting GSR II: BSIS, MOIS, ISA, DDAW, REIS, and the Smart Dash digital cockpit (up to 12.9”). Safety features include a rollover airbag and short-nose, forward-set front axle optimizing brake dynamics. Telematics, flexible maintenance scheduling, and full compatibility with HVO and FAME biodiesel align with VECTO CO2 class efficiency for toll and fleet optimization.
