Cummins Financials



In late July, Cummins reported its second quarter revenue was $4.8 billion USD, up 7 percent from the same quarter in 2013.



Revenues in North America increased 14 percent while international sales decreased 1 percent compared to the second quarter a year ago. Within international markets, lower revenues in Mexico, Brazil and India offset stronger demand in China.



Earnings before interest and taxes (EBIT) were $657 million for the second quarter or 13.6 percent of sales. This compares to $621 million or 13.7 percent of sales a year ago.



Net income in the second quarter was $446 million, compared to $414 million in the second quarter of 2013, up 7.7 percent.



Cummins expects full year 2014 revenues to grow between 8% and 11%, up from its previous forecast of growth of between 6% and 10%, due largely to improving demand in North America. EBIT is expected to be in the range of 12.75 to 13.25 percent of sales.

Cummins 6.7L Turbo Diesel Emissions Highlights



Cummins 6.7L Turbo Diesel is now California Air Resources Board (CARB) LEV III certified; the first such medium duty engine to do so.



The new standard applies to all vehicles under 14,000 lb GVWR. The Cummins 6.7L Turbo Diesel drive the Ram 2500/3500 (MD4) and 4500/5500 Chassis Cab (MD5) Heavy-Duty lineup.



The 2015 6.7L Cummins is the first medium-duty diesel engine in the 8,501-14,000 lb GVWR segment (MD4) to be certified to the new 2015 LEV III standards.



Under the upcoming LEV III emissions standards, the nitrogen oxide (NOx) and non-methane organic gas (NMOG) standards are combined into a single NOx+NMOG certification with a fleet average in 2025 of just 0.030 g/mi.



The new certifications also include an emissions-useful life which was increased from 120,000 (LEV II) to 150,000 miles (LEV III) for emissions control systems.

According to DieselNet, the 2015 Cummins 6.7L engine tune was certified in two configurations. The MDV4 (8501-10000 lb) was certified as a LEV 3 ULEV340 (NMOG+NOx ≤ 0.340 g/mi), with a certification NMOG+NOx = 0.1362 g/mi (FTP).



This compares favorably to the 2014 Cummins 6.7L engine tune as LEV II with a combined NOx and NMOG level of 0.154 g/mi (0.15+0.004). This amounts to an 11.6 percent reduction in combined emissions.



For the heavier MDV5 (10001-14000 lb) 2015 Cummins 6.7L engine tune, it is now certified as LEV 3 ULEV570 with a certification NMOG+NOx of 0.206 g/mi.



This also compares favorably to the 2014 Cummins 6.7L engine tune with a combined NOx and NMOG level of 0.223 g/mi (0.22+0.003). This amounts to a 7.6 percent reduction in combined emissions.

Even though engines were produced for Chrysler to support a model-year 1989 launch, the relationship began in the fall of 1981 when Cummins pitched the B Series engine to Chrysler. Talks continued for four years, and then in April 1985, Chrysler agreed to offer the Cummins 5.9L Turbo Diesel in its Ram pickup. By 1988 they were available at Dodge/RAM pickup dealerships nationwide. Since that time, Cummins has shipped > 2 million engines.
