U.P.S. Is to Put 150 Plastic-Body Trucks Into Service - New York Times The trucks are expected to be received in the fourth quarter of 2012 and to go into service on high-mileage routes, primarily in the Western region of the United States. Lynnette McIntire, a sustainability spokeswoman for U.P.S., said the field test proved to the company that the CV-23 would meet all durability challenges, adding that composites could eventually find use in longer-range and heavier U.P.S. trucks. Test trucks have a composite floor, but aluminum will be used in the production version. Ms. McIntire said the body panels were made with the desired brown shade when they were cast and would not show scratches or require painting.
