The Cummins ISB has a long reputation as the most fuel efficient engine in the motorhome industry. The ISB utilizes the Cummins Variable Geometry Turbocharger (VG Turbo) and High Pressure Common Rail (HPCR) fuel system to produce outstanding driveability, integrated exhaust braking and, arguably, the quietest diesel engine in a motorhome today. Its industry-leading fuel economy, extended oil change intervals and minimal maintenance requirements also make the ISB the low-cost-of-ownership leader in its class.

Whether you're rushing paramedics to an accident scene or responding to a brush fire, you can count on Cummins ISB. Every call. Every time. The 2007 ISB combines increased displacement (5.9 liters to 6.7 liters) and High Pressure Common Rail fuel injection with our patented Variable Geometry Turbo to deliver stronger performance at every rpm. Multiple injection events per cycle also make the ISB run extremely quiet.

Cummins ISB raises the bar for performance and productivity in every type of medium-duty truck, P&D van or other vehicle. At the same time, it lowers noise by as much as 80% and meets every EPA and Euro emissions standard through 2006. In other words, we’ve taken an engine that has proven worldwide acceptance (over 3 million sold) and improved it in virtually every aspect, from acceleration to pulling power (up to 350 lb-ft of clutch engagement torque) to fuel economy (increased by as much as 2%).
