For superior performance, exceptional fuel efficiency and incredibly strong braking power, ultra-luxury motorhome owners choose Cummins ISX. Every time.

With ratings from 525-600 horsepower, the ISX delivers uncompromising performance for towing heavy loads and climbing steep mountain grades. Standard features include the patented Variable Geometry Turbocharger (VG Turbo), now with electric actuation for enhanced engine response at every rpm. While the standard Intebrake system produces over 600 braking horsepower for superior driver control on downhill slopes.

Plus, the ISX is certified and compliant to the toughest standards — the 2007 EPA emission regulations. A Cummins-designed and built particulate filter reduces particulate matter by over 90%, and a crankcase ventilation system virtually eliminates oil carryover. Best of all, there’s very little maintenance to these components, along with the rest of the engine.

Ask any owner, and they’ll tell you that ISX reliability is second to none. Every ISX is backed by the most extensive customer support network in the industry, with programs like Coach Care™ to meet your service needs as you travel across North America in your motorhome.
