Does Cummins Make the World’s Best Diesel Engines?

Ask a dozen friends, “Who makes the best pizza?” and you’re bound to get a dozen different answers. Ask a dozen experts, “Who makes the best diesel engine?” and you’ll likely hear one name more than any other – Cummins. From road to rail, water to worksite, Cummins is a world leader in diesel engine manufacturing. Here’s why…


Cummins is dedicated to giving our customers the power they need to get the job done. Our diesel engines are engineered to maximize torque and horsepower. From efficient 49-horsepower (37 kW) off-highway engines to mammoth 4400-horsepower (3132 kW) rail engines, we design every Cummins diesel to deliver exactly what’s needed for your specific application. In the pickup truck market, our 6.7-liter inline six-cylinder boasts 385 horsepower (287 kW) and 900 pound-feet (1220 Nm) of best-in-class torque, 50 pound-feet (68 Nm) more than the competition. For tough jobs, there’s no substitute for power.


An engine is only as valuable as the work you get out of it. That makes uptime the most critical metric for any engine, and that’s where Cummins truly outshines the rest. Our engines are precision-crafted to resist wear and deliver a lifetime of reliable service. Legendary endurance and low maintenance are Cummins hallmarks. Many Cummins-powered trucks easily surpass the million-mile mark. When our engines do need parts or service, the Cummins network of more than 7,000 dealer and distributor locations provides the best service density in the business.


Cummins diesel engines can be found in a wide variety of vehicles and equipment. While most consumers know us for the Turbo Diesels that power Nissan TITAN XD and RAM 2500 and 3500 pickups, or for our popular big rig engines, we also produce diesel engines for industrial applications around the globe. Cummins engines power everything from agriculture and construction equipment to power generators and marine vessels. Collectively, our engines have been tested in every environment on Earth and proven their worth for hundreds of different uses.


Since our founding nearly 100 years ago, Cummins has pioneered new innovations in engine technology. Clessie Cummins launched the company in Columbus, Indiana in 1919, with a commitment to producing the finest diesel engines on the planet. From humble beginnings grew an international enterprise that today provides products and service to customers in more than 150 countries. Nearly a century spent amplifying diesel engine performance provides Cummins unmatched insight and expertise.


At Cummins, innovation isn’t just a word; it’s ingrained in our culture, our vision, our mission and our values. From producing the first diesel-powered racecar to break the 100-mph (161-kph) barrier back in 1931, to partnering with Dodge to haul two tons more than any competitor in 1989, to meeting 2014 EPA and NHTSA greenhouse gas regulations a full year ahead of schedule across our entire on-highway product line-up, we’re always pushing the boundaries. Today, Cummins engineers around the world are developing and testing the next generation of new technologies to improve customers’ lives and productivity – including surpassing the next wave of global emissions standards.
