Workhorse Custom Chassis, which was acquired by International Truck & Engine Corp. this summer, has announced the production launch of its first diesel chassis powered by an International diesel engine. The new W42 Workhorse chassis boasts the International VT275 4.5L diesel, a V6 engine rated forh 200 hp and 440 lb.-ft. of torque.

“We’re very excited about this new chassis,” said Jay Sandler, vp of commercial products for Workhorse. “We’ve been strong in the gas market, but did not have a diesel in 2005.
