When it comes to Uptime, we’re all business
The Cummins B6.7™ is one of the most dependable and durable medium-duty engines available. It’s been tested and proven with more than 13 million engines produced over nearly 40 years, with billions of miles driven. We’re proud of this history and proud that Cummins medium-duty products power more trucks across North America than any other engines.
The EPA 2021 B6.7 builds on this legacy. We listened to our customers and focused on making enhancements to reliability and durability while lowering the total cost of operation (TCO), helping to keep trucks on the road longer. Others talk a big game, but only Cummins delivers uptime … big time.
New for EPA 2021, the B6.7 features upgrades that allow for extended engine maintenance intervals, including longer oil drain intervals, more time between fuel filter changes and a completely maintenance-free crankcase ventilation filter. That means trucks go longer between trips to the garage for regular maintenance and more money back to your bottom line. Also new for 2021, the B6.7 offers advancements in connectivity to find, prevent and resolve issues faster.
Of course, the B6.7 is also backed by the best warranty and extended coverage plans in the industry and the largest, most capable support network in North America.

Cummins designs, develops and supports every component, from the air handling to the exhaust aftertreatment, to work as a totally integrated system – so we can optimize every function better than other engine manufacturers.
- VGT Turbo from Cummins Turbo Technologies – This patented design is widely recognized as an industry performance leader. The refined design improves responsiveness in the B6.7 while an upgraded bearing system increases overall robustness. The VGT Turbo is a key element in providing increased fuel economy and exceptional braking horsepower
- Connected Diagnostics™ – Wirelessly connect your engine to Cummins through a telematics device for immediate diagnosis of a fault alert. Within seconds, Connected Diagnostics provides a clear recommendation for continued operation or the need for service.
- High Pressure Common Rail (HPCR) Fuel System – Delivers superior performance even in lower engine rpm ranges. Enables multiple injection events per cycle, for improved fuel efficiency with quieter, smoother operation.
- Air Handling System – A more robust Exhaust Gas Recirculation (EGR) cooler and valve enhance thermal efficiency and reliability.
- Single Module Aftertreatment From Cummins Emission Solutions – Combines high-efficiency SCR, a more reliable dosing unit and a DPF into a single flow-through unit. It is up to 70 percent smaller, so it’s easier to install, and as much as 30 percent lighter than the aftertreatment units it replaces. Better heat management improves fuel efficiency and minimizes periodic maintenance.
- Fuel Filters And Lube Filters From Cummins Filtration – Fleetguard® filters protect against corrosion and contaminants with innovative NanoNet® technology. NanoNet media provides 10 times better protection than conventional fuel filters for lower cost of operation.
- Single High-Capacity Electronic Control Module (ECM) – Offers higher capacity for faster processing of more information, fully integrated control over the engine and aftertreatment system for optimized performance and improved engine lamp strategy.
