Workhorse Custom Chassis, an affiliate of Navistar International, has upgraded its W62 chassis for walk-in trucks.
The company had a UPS delivery truck with the upgraded W62 gas-powered chassis on display at the National Truck Equipment Association Work Truck Show in St. Louis.

The Workhorse gas chassis features the improved 6.0-liter GM Vortec gasoline engine, designed to achieve up to 20 percent better fuel economy than the previous 8.1-liter Vortec gasoline engine, the company claims.

The UPS truck is one of a number of units built on the W62 gas platform that UPS will use to evaluate fuel economy for its duty cycle. Production of the 2011 W62 model will begin this summer. The 6.0-liter V-8 gasoline engine uses variable valve timing and an Allison 5-speed 1000HS transmission. It also comes with several extended warranty options.

Workhorse has also begun offering the new 2010 6.4-liter MaxxForce 7 diesel powertrain for its 2010 W62 diesel platforms. The 2011 models will feature the MaxxForce 7 with MaxxForce Advanced exhaust gas recirculation technology.

"The fact that we offer both gas and diesel choices, with durable and dependable platforms powered right for the job, makes it easier for commercial walk-in truck users to meet their bottom line-both in terms of fuel consumption and work efficiency," said Jim Gavaghan, Workhorse vice president, sales, service and warranty.
