Class 8 Truck FAQ
What is a Class 8 truck?
A Class 8 truck has a Gross Vehicle Weight Rating (GVWR) over 33,000 lbs. This is the heaviest commercial truck class under the US DOT system and includes long-haul tractor-trailers (18-wheelers), heavy-duty dump trucks, concrete mixers, tankers, and other vocational trucks. Class 8 vehicles require a Class A CDL when used in combination with a trailer, or Class B for single-unit straight trucks.
What brands make Class 8 trucks?
The primary Class 8 manufacturers in North America are Freightliner (Daimler Trucks), Kenworth (PACCAR), Peterbilt (PACCAR), Volvo Trucks, International (Navistar), Mack Trucks (Volvo Group), and Western Star (Daimler). Each OEM offers line-haul, regional, and vocational configurations with proprietary or third-party engine options.
What does a Class 8 truck cost?
New Class 8 tractors range from roughly $150,000 for a base day cab to over $200,000 for a fully optioned sleeper. Vocational Class 8 trucks (dump, mixer, tanker) vary widely by body and spec. Used Class 8 trucks are available from around $25,000 for older high-mileage units to $150,000 for late-model, low-mileage sleepers. Fleet disposals (3–5 years old, 400k–700k miles) typically run $60,000–$100,000.
What engines power Class 8 trucks?
Common Class 8 diesel engines include the Freightliner Detroit DD15 (up to 505 hp), PACCAR MX-13 (up to 510 hp), Cummins X15 (up to 605 hp), Volvo D13 (up to 500 hp), Mack MP8 (up to 505 hp), and International A26 (up to 475 hp). Most 2020+ models pair these engines with automated transmissions — Detroit DT12, PACCAR TX-12, Volvo I-Shift, or Eaton Endurant.
What is the fuel economy of a Class 8 truck?
Modern aerodynamic Class 8 sleepers achieve 7–9 MPG in long-haul service with a loaded trailer. Day cabs on regional routes average 6–8 MPG. Vocational Class 8 trucks (dump, mixer, tanker) typically see 4–7 MPG depending on duty cycle and terrain. Fuel economy depends heavily on load, speed, terrain, engine calibration, and aerodynamic equipment (skirts, fairings, APU).
What should I check when buying a used Class 8 truck?
Pull the ECM report to verify engine hours, idle time, and fault codes — a truck with high idle percentage has more wear than miles suggest. Inspect the aftertreatment system (DPF, SCR, DEF) for faults; repairs run $3,000–$10,000. Check frame rails for cracks, prior repairs, or misalignment. Test all air systems. For sleepers, inspect the bunk heater or APU. Always obtain service records and run a VIN history report.
