Cummins RV Engines
Premium motorhome buyers don't settle for second best. That's why the number-one choice for diesel-powered motorhomes is Cummins. They offer a broad range of power for every size motorhome on the market. Plus, their 2007 engine and aftertreatment system reduces particulate matter by more than 90% without compromising performance, reliability or durability.
The Number-one Choice for Diesel-Powered Motorhomes
Designed To Deliver Every Advantage.
Of all diesel engine manufacturers, only Cummins designs and manufactures the complete system from air intake to exhaust system totally in-house. It’s a
process that gives us the ability to optimize every aspect of performance, on every engine from the ISB to the ISX.
The Cummins lineup of engines not only meets EPA ’07 and CARB emissions regulations, they do so without compromising fuel efficiency, reliability or power. Their fully integrated system includes a proven cooled-EGR
subsystem, a high-pressure fuel system, the patented VG Turbo, exhaust aftertreatment, combustion technology and advanced electronic engine controls, all designed to function as a single unit.
Cummins engines are built to give motorhome owners every advantage. That’s why Cummins continues to be the #1 choice in diesel power by an overwhelming margin.
- ISX Dual overhead cams, an integrated engine brake, and 525-650 horsepower from the most fuel efficient engine in its class.
- ISM Designed for long-distance cruising up and down the interstate. With the highest power-to-weight ratio in its class, the ISM 450 and 500 horsepower ratings let you climb every mountain.
- ISL The ideal engine for larger luxury motorhomes. With power up to 425 hp and 1200 lb-ft of torque, the ISL can accelerate at any speed and quickly climb the steepest grades even when towing. The ISL offers a very strong engine brake for extra braking capacity and added driver control. With 20,000 mile (32,000 km) oil change intervals, the ISL saves money and time when it comes to maintenance.
- ISC Built on a reputation of delivering additional performance when a little extra is needed. With up to 360 horsepower and 1050 lb ft of torque, the ISC is designed to provide the performance to deal with heavier loads and steeper grades.
- ISB The ISB XT combines the performance of 350 horsepower and the industry-leading fuel economy of the legendary ISB to set a new standard for the 350 hp motorhome. The "XT" in its name refers to the extra displacement (6.7 liters), extra power for acceleration and climbing hills, and extra stopping power of the integrated exhaust brake from its Variable Geometry Turbocharger. The ISB family also includes 340 and 300 horsepower ratings for motorhome applications along with the ISB AD models which are used in front engine diesel chassis.
Cummins electronic diesel engines are backed with a 5-year/100,000-mile (160,935 km) standard warranty, which is supported by the most extensive customer support in North America. ISB AD ratings have a standard base warranty of 3 years/75,000 miles (120,701 km).
