New 2024 Kenworth T680 Review. Cummins x15 | 450 hp | 76 inch raise roof. The new t680 is definitely a “next generation” truck for kenworth, and one that builds nicely on its existing reputation.
The truck is a technological tour de force that offers something for everyone in fleet operations today. However i saw a couple on the road and truck stops and seems the new aerodynamic bits and pieces are falling apart on these technically brand new trucks.
