Specific model/size not provided, but common for JCB would be Cummins, Perkins, or JCB's own diesel engines. Performance Horsepower Range Estimated: Typically 200-300 HP range for a truck of this class, but can vary significantly based on specific configuration. Torque Range Estimated: Likely 500-800 lb-ft, providing substantial pulling power. Fuel System Fuel Type: Diesel Injection System: Common Rail Direct Injection (CRDI) or similar modern diesel injection technology, requiring specific electrical control. 🔧 Transmission Standard Transmission Type: Likely an automatic or manual heavy-duty transmission. Automatic transmissions (e.g., Allison, ZF) are common in this class and have complex electronic controls. Optional Transmission Options: Could include different gear ratios or specialized heavy-duty manual transmissions. Features Electronic Control: Many modern heavy-duty transmissions feature electronic control units (TCUs) for shift logic, requiring specific wiring and sensor inputs. 📐 Dimensions Exterior Vehicle Class: Heavy-Duty Truck / Commercial Vehicle Configuration Options: Likely available in various configurations such as tractor units, rigid trucks, or specialized chassis for mounting equipment. Weights Gross Vehicle Weight Rating Gvwr Estimated: Typically in the Class 8 (GVWR > 33,000 lbs or ~15,000 kg) range, often exceeding 50,000 lbs (22,680 kg). 🛡️ Safety Features Ratings Safety Compliance: Must comply with relevant national and international heavy vehicle safety standards (e.g., FMVSS in the US, ECE regulations in Europe). Active Features Anti Lock Braking System ABS: Standard on most modern heavy-duty trucks, electronically controlled and integrated into the braking system's wiring. Electronic Stability Control Esc: Increasingly common, also requiring dedicated sensors and wiring. Passive Features Lighting Systems: Includes regulations for headlights, taillights, brake lights, turn signals, and side marker lights, all managed by the vehicle's electrical system. Cab Construction: While not directly electrical, the electrical systems power safety features within the cab (e.g., warning lights, seatbelt pretensioners if fitted). 💡 Technology Features Infotainment Cabin Features: Basic to advanced infotainment systems can be integrated, including radio, CD/MP3 players, Bluetooth connectivity, and potentially navigation, all requiring electrical power and CAN bus integration. Driver Assistance Advanced Driver Assistance Systems Adas: Depending on the year and specification, may include features like cruise control, potentially lane departure...
