When you say the word "efficiency" to anyone in the trucking industry, the conversation immediately turns to fuel economy – for good reason. It’s one of the single most important factors in your total cost of operation.  And that’s why Cummins is redefining a classic and introducing the newest-generation B Series engine from Cummins – the B6.7. The Cummins B6.7 for 2017 is more efficient, with up to 7 percent better fuel economy over the EPA 2013 ISB6.7, with the highest gains in key duty cycles running at lower speeds and in inner-city operations.

SmartEfficiency: High-Achieve and Cost-Lowering The Cummins SmartEfficiency initiative is a focused approach that improves uptime and reliability while providing a broad spectrum of reliable engine choices to meet every need. The combination of a low cost of operation, high reliability, clean operation and long-term durability are unsurpassed in the industry. The fact that all Cummins engines use the same control system technology and can be serviced at any authorized Cummins location ensures serviceability anywhere, anytime

From ambulances to wildland firefighting equipment, the B6.7 is designed in Indiana and built in North Carolina specifically for the fire service, with maximum performance and reliability. Designed For The Fire Service.

American ingenuity and over 30 years of continuous improvement have made the Cummins B6.7 a standard in reliability and performance for motorhomes and thousands of other applications, from RAM trucks to minehunters serving our armed forces. Because they provide higher confidence, performance and reliability, you deserve a diesel. Confidence.
