Workhorse Custom Chassis is the first manufacturer to offer the all new, power-enhanced CatÂ® C7 engine in a motor home chassis.
Gulf StreamÂs Crescendo and Yellowstone rear diesel motor homes are the first to use WorkhorseÂs Cat-powered diesel pusher chassis. The new models were introduced at the California RV Show in Pomona this fall. The Yellowstone model immediately sold to a couple from Palm Desert, Calif. The chassis was also one of the highlights at the National RV Trade Show in Louisville, Ky., last week.
The rear-engine diesel platform has a GVWR range of 28,000 to 32,000 lbs. and includes an Allison 3000 MH six-speed automatic transmission. It is available on all Crescendo and Yellowstone models from 36 to 40 feet. Workhorse is using the most powerful C7 developed to date, with 360 horsepower and 925 lb.-ft. of torque. The new engineÂs common rail fuel system and variable nozzle turbocharger, enhanced electronics, and turbo brake all work to improve performance and lower operating costs.
Powerful engine, performance platform
The Workhorse R Series diesel chassis is WorkhorseÂs other rear engine chassis, not to be confused with the Workhorse UFOÂ chassis that was launched last year. The R Series is known for outstanding ride and handling and rugged reliability.
Last year many chassis manufacturers consolidated diesel engine offerings, which provided Workhorse an opportunity to use the Caterpillar powerplant.
ÂThe Cat has a loyal following among many RVers,Â said Bill Walmsley, director of RV marketing for Workhorse. ÂSo we are pleased to offer the engine in the mid-range diesel marketplace. ItÂs an excellent engine, and Caterpillar has been building a first class RV service network for it. The top-end C7 model we are using will provide a perfect complement to the superior ride and handling of the R Series diesel. It supplies the power and performance desired in this class of motor homes.Â
ÂWe are pleased to be the exclusive engine offering in the Workhorse R Series diesel chassis and look forward to introducing this product to the RV market,Â said Suzie Adcock, Caterpillar senior account manager, OEM Sales Division. ÂThe new, more powerful rating makes this engine the best C7 option yet for RVers, and weÂre glad we can continue to be a significant presence in this market. Our Cat RV Center network continues to add new locations and we remain committed to giving RVers the same reliability, durability and fuel economy advantages that Cat engines have always delivered.Â
Recently Caterpillar Inc. received the prestigious J.D. Power and Associates Award for ranking highest in customer satisfaction for its Pickup and Delivery Heavy-Duty diesel engines as part of the 2007 Heavy-Duty Truck Engine/Transmission StudySM. This award is the tenth that Caterpillar has received from J.D. Power for heavy-duty truck engine satisfaction in the 11 years the study has been undertaken.
ÂCat and the R Series is a terrific combination that weÂre proud to be a part of,Â said Walmsley.
Advanced emissions technology
CatÂs C7 is 2007 emissions compliant thanks to its ACERT Technology that positions it to meet future EPA emissions regulations and provides a long-term emissions solution. ACERT Technology relies on four basic systems to lower emissions Â air management, precision combustion, advanced electronics and effective after-treatment. These systems reduce particulate matter, oxides of nitrogen and hydrocarbon emissions while preserving the engineÂs reliability and durability, which keep operating costs low.
ÂACERT is a very efficient system for restricting emissions and requires less service than many competing technologies,Â said Walmsley. ÂThereÂs little the RV owner needs to be concerned about, except having a good time driving it.Â
Excellent road performance
The R Series diesel is a proven dream to drive. The front and rear suspensions are uniquely designed to work as a unit for optimal handling. Air bag placement, engine placement, V-rod stabilizer, dual leveling valves and a parallelogram suspension are among the systems Workhorse integrated to provide a greater feeling of comfort and control. Test drivers immediately notice the reduced body roll and tail wag, along with minimal noise and vibration. With the R Series, the coach maintains superb balance and stability.
Furthermore, Workhorse SmartChassis engineering also designed the R Series to be easy to own, with less maintenance and complexity, giving RVers more time to enjoy the lifestyle theyÂve chosen. For example, the Workhorse Integrated Smart Electrical (WISEÂ) system can provides a chassis ÂbrainÂ to monitor all of the electronic systems on one panel and indicate whether everything from light bulbs to brake systems are working properly, depending on manufacturer integration.
The R Series also eliminates such things as complex ping tanks and related hardware to reduce the potential for air leaks and other complications. It has automatic heated moisture ejectors on both air tanks to prevent freeze-ups and eliminate the need to crawl under the coach to manually open a valve. It has a fixed pneumatic compressor discharge line with no low points so moisture canÂt collect and freeze.
Overall, the R Series is designed to do more with less to make life on the road more enjoyable and trouble-free. Many of its innovations have been duplicated elsewhere, making the R Series a significant contributor to the overall development of motor home technology in recent years. Now that the Cat C7 is offered, the Workhorse R Series diesel is ready to turn another page in the advancement of motor home enjoyment.
