Common engines for this class of chassis typically include Cummins ISB/ISF, Navistar MaxxForce, or DT series, and Detroit Diesel DD series. Engine displacement can range from 5.9L to 6.7L or higher. Performance Horsepower Torque Inference: Typical horsepower ratings for these chassis range from 200-325 HP, with torque figures from 520-750 lb-ft, depending on the specific engine and application requirements. Fuel System Fuel Type: Diesel (standard). Hybrid variants will incorporate electric drive components. Injection System: Commonly Common Rail Direct Injection (CRDI). Emissions Control Emissions Systems: Likely includes Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR) with Diesel Exhaust Fluid (DEF), and Exhaust Gas Recirculation (EGR). 🔧 Transmission Standard Transmission Type Inference: Often equipped with heavy-duty automatic transmissions like Allison 1000/2000 series or similar commercial-grade automatics. Manual transmissions are less common in this specific application but not entirely out of the question for certain configurations. Optional Transmission Variants: Hybrid variants will feature integrated electric motors and power split devices. Features Transmission Features: Torque converter, electronic controls, power take-off (PTO) provisions are common. 📐 Dimensions Exterior Wheelbase Range: Variable, typically from 108 to 178 inches (approx. 2743mm to 4521mm) or more, depending on body configuration and customer requirements. Overall Length Range: Highly variable based on body builder, typically 20-30+ feet. Weights Gvwr Range: Gross Vehicle Weight Rating (GVWR) commonly ranges from 14,000 lbs to 26,000 lbs (Class 3-5), with potential for higher ratings on the MT55. Curb Weight Inference: Curb weight varies significantly based on chassis configuration and body, but typically ranges from 6,000 lbs to 10,000+ lbs for the chassis itself. 🛡️ Safety Features Ratings Crash Test Inference: As a chassis cab, crash test ratings are primarily for the cab structure itself. Manufacturers like Freightliner typically meet or exceed federal safety standards (FMVSS). Specific body integrations will have their own safety considerations. Active Features Braking System: Hydraulic disc brakes (front and rear) with ABS are standard. Air brakes may be an option on heavier configurations. Traction Control: Electronic Traction Control (ETC) is a common feature. Passive Features Restraint Systems: Driver and passenger airbags, seat belts are standard. Cab Construction: Reinforced cab structure for driver protection. 💡 Technology Features Infotainment Infotainment Options Inference: Basic infotainment systems are common, often including AM/FM radio, auxiliary input, and potentially Bluetooth connectivity. More advanced options are rare in base chassis but can be added by upfitters. Driver Assistance Driver Assistance Features: ABS is standard. Other advanced driver-assistance systems (ADAS) like lane departure warning or adaptive...
