FOR IMMEDIATE RELEASE
Cat® C7 engine to power Workhorse R Series Diesel chassis
UNION CITY, IN, November 22, 2006
"” And now, you can get a Workhorse with a Cat®
Workhorse Custom Chassis
are announcing another new choice for motor home owners. Starting in April, the Workhorse R Series Diesel chassis will be exclusively powered
by a C7 Caterpillar diesel engine.
Caterpillar is the RV market leader in diesel power and a fitting match for one of the most innovative diesel chassis on the market, said Bob Wert, Workhorse vice president of sales and marketing. "We are the customer's advocate to the RV industry,"¯ said Wert. "We are dedicated to bringing new choices to the RV consumer, and based on what we know consumers want, this was an irresistible match to make."¯
The 2007 C7 used for the R Series is an in-line, 6 cylinder, 7.2 liter powerplant with a 4-stroke cycle that generates 350 hp at 2,400 rpm and 925 ft.-lbs. of torque at 1,440 rpm. It is fully compliant with'07 emissions standards, using Caterpillar's unique ACERT™ Technology.
ACERT uses a Diesel Particulate Filter that replaces the diesel oxidation catalyst and reduces sound to eliminate the need for a muffler. Made from ceramic material, Cat's DPF employs "wall flow"¯ technology to capture particulate matter, or soot, from the exhaust gas, which the engine heat oxidizes. In cases of extended idling or low ambient temperatures, where not enough engine heat is generated, the proprietary Cat Regeneration System takes over to oxidize the remaining soot. This method of emissions reduction results in improved engine response, increased fuel economy and better performance. What all this means is NO customer intervention in the regeneration process.
Additional changes to the 2007 R Series Diesel will include the introduction of Workhorse's patented WISE™ (Workhorse Integrated Smart Electrical) multiplexing system, which puts all of the coach's electrical systems under one control center to simplify monitoring and control.
"A great chassis has just gotten better,"¯ said Wert. "We have a number of manufacturers very interested in this development, and we think the R Series Diesel's time has come to shine in this market."¯
The R Series Diesel has received high marks for its excellent ride and handling from owners and test drive surveys. This is due to its groundbreaking design that includes a more forward and lowered engine placement and rear parallelogram suspension with a V-rod sway bar, which helps reduce tail wag and decrease body roll. It also makes innovative use of existing technology to provide superior cooling.
The R Series Diesel has GVWR options of 28,000, 29,000 and 32,000 lbs. It currently uses a raised rail construction with a main frame of 50,000 psi steel. An I-Beam front suspension with custom-tuned air springs along with front and rear Gabriel® Ryde FX shock absorbers further contribute to the platform's excellent stability and ride.
