Category Breakdown
Fuel Economy
Kenworth T680 winsThe T680's aerodynamic cab design and optimized drivetrain deliver class-leading fuel economy for a Class 8 truck. The W900's traditional long-nose design sacrifices 15-25% in fuel economy compared to the T680.
Resale Value
Kenworth W900 winsThe W900 is arguably the best-holding value in all of trucking. Its iconic status means demand for used W900s consistently exceeds supply. A well-maintained W900 can sell for near-purchase price after 5 years. The T680 depreciates at a more normal rate.
Cab Comfort
Kenworth W900 winsBoth offer excellent interiors, but the W900's wider cab provides slightly more elbow room. The T680 counters with better noise insulation and a more modern dashboard layout. Sleeper berth options are comparable.
Payload Capacity
Kenworth T680 winsThe T680 is slightly lighter due to its aluminum and composite construction, giving it a small payload advantage. This matters for weight-sensitive commodities where every pound counts.
Driver Recruitment
Kenworth W900 winsFleets running W900s have an easier time recruiting and retaining drivers. Many experienced drivers will take lower pay to drive a W900. The truck itself is a recruitment tool that the T680 simply cannot match.

Our Verdict
The Kenworth T680 wins on operating economics — fuel savings of $10,000-$20,000 per year make it the smarter financial choice for most operations. Large fleets overwhelmingly choose the T680 for its efficiency.
The W900 wins on everything money cannot easily measure: driver satisfaction, recruitment advantage, resale value, and the intangible pride that comes with driving the most iconic truck on the road. For owner-operators, the W900's resale value can offset much of the fuel penalty.
