Typical Torque Range: Significant torque output, crucial for heavy-duty hauling, typically exceeding 1000 Nm for larger displacement engines. Fuel System Fuel Injection: Typically features direct injection, with mechanical or electronic injection pumps (e.g., Bosch rotary or inline pumps, later EDC - Electronic Diesel Control). 🔧 Transmission Standard Gearbox Options: Various Scania manual transmissions (e.g., GR800, GR900 series with overdrive) and potentially Scania Opticruise (automated manual transmission) on later 4-series models. Optional Transmission Types: Range of manual gearboxes with different gear ratios and speeds (e.g., 8, 12, 16 speed configurations), potentially ZF or Allison automatics as OEM options. Features Gearshift Mechanism: Direct shift or remote shift linkages for manual transmissions; electronic or hydraulic actuation for automated/automatic transmissions. 📐 Dimensions Exterior Cab Configurations: Variety of cab types: Day cab, Sleeper cab (low or high roof), Crew cab (less common). Exact dimensions vary greatly by specific model and chassis configuration. Weights Gvwr Gcwr: Gross Vehicle Weight Rating (GVWR) and Gross Combined Weight Rating (GCWR) vary significantly based on axle configurations, engine, and intended application, often ranging from 18,000 kg (40,000 lbs) GVWR up to 60,000 kg (130,000 lbs) GCWR or more for specialized haulage. 🛡️ Safety Features Ratings Crash Test Data: Specific crash test data for these vintage models may be limited or vary by region. The manual would detail structural integrity and passive safety features of the era. Active Features Braking System: Predominantly air brake systems with ABS (Anti-lock Braking System) available on later models and higher specifications. Parking brake, exhaust brake/retarder. Passive Features Occupant Protection: Reinforced cab structure, seat belts (typically three-point), energy-absorbing steering column. 💡 Technology Features Infotainment Cab Features: Basic amenities for the time, including radio/cassette player, optional CB radio, climate controls (manual or semi-automatic HVAC). Limited to utilitarian functions. Driver Assistance Assist Features: ABS (Anti-lock Braking System) became more common during this period. Some models may have offered retarders for enhanced braking. Connectivity Diagnostics Interface: Early diagnostic capabilities may rely on proprietary Scania diagnostic tools or basic OBD-II interfaces...
