Cummins Inc. announced the release of its most powerful ISX in years, with 600 horsepower and 2050 lb.-ft. of torque. This new rating is designed for heavy-haul customers, fleets and owner/operators who specialize in expedited freight. It is scheduled to be available this fall.

Extra torque allows drivers to maintain road speed even on steep inclines, reducing the number of downshifts and fuel consumption. Maintaining a higher average road speed with less shifting also reduces driver fatigue and shortens trip time.

In addition to stronger pulling power, the ISX for 2007 also includes electric actuation on the patented VG Turbo, for improved engine response across the entire power range. The Intebrake system, an integrated compression brake that generates more than 600 braking horsepower, continues as standard equipment.

Cummins also announced the next generation of QuickCheck engine information tools – the QuickCheck 5100. This new product brings the power of a portable computer and proprietary engine-monitoring software into one handheld device.

The feature-rich QuickCheck 5100 is a self-contained device that makes capturing and reading engine data easier and faster, the company said. The shop-rugged weather-resistant handheld device is specifically designed and built for extreme environmental conditions. The QuickCheck 5100 connects to any electronic diesel engine, using standard J1587 or J1939 data links with supplied 6- or 9-pin cables. A supplied USB cable allows users to link their QuickCheck 5100 to a desktop PC.

The QuickCheck 5100 runs on the Windows CE operating system and is preloaded with QuickCheck CE and PowerSpec CE applications, so it’s ready to work right out of the box.

Cummins also announced the approval of biodiesel B20 blends for use in its 2002 and later emissions-compliant ISX, ISM, ISL, ISC and ISB engines. This includes the recently released 2007 products.
