Category Breakdown

Fuel Economy

Kenworth T680 wins
Kenworth T68090
Kenworth W90060

The 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 wins
Kenworth T68072
Kenworth W90092

The 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 wins
Kenworth T68084
Kenworth W90086

Both 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 wins
Kenworth T68082
Kenworth W90078

The 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 wins
Kenworth T68070
Kenworth W90088

Fleets 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.

Choose the T680 if you run the numbers. Choose the W900 if you run your heart.

Frequently Asked Questions

The W900 represents everything owner-operators love about trucking — it is big, powerful, distinctive, and commands respect. Its outstanding resale value means it is actually a reasonable financial decision despite lower fuel economy. Many owner-operators view it as the ultimate reward for years of hard work.
Kenworth has no announced plans to discontinue the W900. Despite industry trends toward aerodynamic trucks, demand for the W900 remains strong enough to justify continued production. It is a cultural icon that Kenworth understands holds value beyond economics.
The W900's traditional long-nose design provides significantly better engine access for maintenance and repairs. The hood tilts forward to expose the entire engine compartment. The T680 requires more disassembly for certain maintenance tasks due to its compact cab-over design elements.
