Scania S730 Used Trucks - Current Offers for Sale

V8 Powertrain and Driveline

The Scania S730 is powered by the DC16 108 16.4L V8, delivering 730 hp (537–544 kW) at 1,900 rpm and a peak torque of 3,500–3,520 Nm (1,000–1,400 rpm). The engine employs a single-cylinder-head-per-cylinder design for thermal efficiency and rapid servicability, with wet liners featuring anti-polishing rings for enhanced durability. Euro 6-compliant units use XPI common-rail fuel injection with multiple injection phases managed by an advanced EMS. The S730’s driveline includes the G33CM automated gearbox, featuring aluminum housing, layshaft braking, dry-sump lubrication, and up to eight reverse gears. The optional "Clutch on Demand" system enables manual clutch control for millimeter-precise maneuvering under heavy loads. The R4100D retarder offers up to 3,500 Nm braking torque with a freewheeling clutch to reduce drag.

Chassis, Axles, and Heavy Haulage Adaptations

S730 configurations range from 4x2 tractors to 10x4*6 heavy-haul variants, supporting GCWs up to 250 tonnes. Chassis design is underpinned by the Modular Architecture Chassis (MACH), enabling predictable mounting points and exceptional flexibility for chassis-mounted equipment. Both single and tandem hub-reduction axles are available, the latter supporting up to 210–250 tonnes GCW with ratios from 3.52 to 7.63. Electronic Level Control (ELC) air suspension is standard, with full kneeling and load-transfer functions. Heavy-haul models incorporate a rear-mounted equipment tower for high-capacity tanks, hydraulic systems, and auxiliary components, plus XT steel bumpers with 40-tonne tow ratings.

Cab Architecture and Ergonomics

The S-series cab features a flat-floor design with up to 2.07 m interior standing height in Highline versions. Extended Longline and Extended Highline variants provide interior lengths up to 3,320 mm for long-haul and oversized transport. The cab includes advanced sound insulation, multi-zone ambient lighting, ventilated exterior storage, and revised seating for optimal road visibility. Aerodynamics and airflow are refined through advanced wind tunnel testing, with multiple roof and side deflector sizes for precise trailer alignment.

Advanced Control, Safety, and Maintenance Systems

The S730 integrates CCAP predictive cruise control, real-time load monitoring, and selectable drive modes (Standard, Economy, Power, Off-Road) via Opticruise. Passive safety is enhanced by rollover curtain airbags and reinforced steel cab construction. Flexible maintenance scheduling leverages telematics, with centrifugal oil cleaning and dynamic oil change intervals. Dedicated service features address EGR valve stiction, XPI fuel system sensitivity, and DEF system thermal management, ensuring reliability in demanding heavy-haul operations.
