Vocational Truck with new offering on display at World of Concrete 2015

LAS VEGAS, Feb. 3, 2015 /PRNewswire/ -- International® Truck announced today the availability of the International® WorkStar® vocational truck powered by the Cummins ISB6.7 engine. The WorkStar is the second International truck model to feature the ISB6.7 as an engine option, following the International DuraStar® which has been in market with Cummins ISB6.7 since December 2013.

"Adding the market-accepted Cummins ISB6.7 to our vocational line-up is a key part of our strategy to offer our customers the most comprehensive options of proven components in the industry," said Bill Kozek, Navistar president, Truck and Parts. "The addition of the Cummins ISB6.7 to our WorkStar model provides customers with a winning combination of uptime, performance, productivity and durability."

International® WorkStar® Features
Built on the same battle-tested truck platform as the International® MaxxPro® MRAP (Mine-Resistant Ambush-Protected) armored vehicle, the WorkStar has the strength and sophistication to take on the challenges of any environment. The WorkStar boasts multiple-frame rail options, a double-sided galvanized steel cab protected by an extensive five-step corrosion protection, and comes standard with the Diamond Logic® electrical system—the most advanced multiplexing architecture available in commercial trucks.

The WorkStar features unique advantages like a hood and radiator package with available integral front frame extension and front engine power take-off (FEPTO) without requiring modifications to the radiator or horsepower restrictions. The WorkStar also features one of the roomiest cabs in the industry and offers both standard and high-visibility sloped-hood configurations for enhanced driver comfort and ease of operation.

The addition of the Cummins ISB 6.7-liter engine now expands the WorkStar model's robust powertrain options, which include Navistar's proprietary 9.3-liter and 13-liter offerings. WorkStar is also available with a suite of traditional manual and automated-manual transmission offerings from Eaton and fully-automatic offerings from Allison. The ISB, which is rated up to 325 horsepower and 750 lb.-ft. of torque, with higher ratings available for fire and emergency applications, features flexible horsepower and torque ratings for medium-duty applications.

"When you put it together, the International WorkStar is the right truck for the toughest of jobs," said David Hillman, general manager, severe service trucks. "With the WorkStar, customers don't have to compromise. They can have it all—efficiency, comfort, functionality, productivity, and now the proven Cummins ISB6.7 engine."

The WorkStar with Cummins ISB6.7 is available for order today and will be in production this spring. The International WorkStar with the Cummins ISB6.7 engine will be on display this week at the International Truck booth (C6283) World of Concrete.
