El Dorado National has begun offering a 9.3-liter MaxxForce® diesel engine in its E-Z Rider II paratransit bus, giving bus fleets a new option in clean diesel power for the demanding duty cycles of public transportation. Pace, the suburban bus division of Chicago-area Regional Transportation Authority (RTA), recently ordered the first MaxxForce-powered E-Z Rider II bus.
“ElDorado is committed to being America’s best bus investment, and that now extends to giving our customers a choice of diesel engines,” said Tony Wayne, president, ElDorado National California. “This allows fleet operators to more carefully weigh decisions concerning operating costs, uptime and service support.”
RTA’s Pace, one of the largest bus services in North America, serves more than 35 million riders a year throughout a 3,700-square-mile area covering six Chicago-area counties. It operates fixed bus routes, vanpools and dial-a-ride programs. Its huge vehicle fleet includes 372 paratransit buses.
The MaxxForce 9 engine provides 300 horsepower and 860 lb.-ft. torque for demanding transit applications. The 32-foot low-floor E-Z Rider II, with a 35,000 lb. GVWR (gross vehicle weight rating), features heavy-duty Meritor axles, large S-cam air brakes, and a transit-proven and crash-tested monocoque safety cage. Together, the engine and paratransit bus are engineered for reliability and durability to meet demanding, real-world operating conditions year after year.
MaxxForce engines from Navistar command a dominant share in other municipal and public services markets like fire and emergency, school bus and waste collection. Overall, Navistar has the most midrange diesel engines installed and in service in North America, and the largest dealer service network to back them up. Now, MaxxForce engines are available to manufacturers and buyers of transit buses, where reliability and durability are crucial in stop/start, frequent-idling operation.
“Navistar is pleased that ElDorado chose our technologically advanced engine,” said Eric Tech, president, Navistar Engine Group. “The MaxxForce 9 provides ElDorado transit customers with the most powerful, durable and environmentally friendly engines available in the market.”
To meet strict emissions standards, MaxxForce engines use Navistar’s advanced in-cylinder NOx-reduction technology, which provides bus fleets with significant no hassle operational advantages over liquid-urea SCR emissions aftertreatment systems used by other diesel engine OEMs. These advantages include no additional wheelbase length to accommodate additional catalysts, no secondary operating fluid (liquid urea) to add, no additional driver training, and ease of maintenance.
To showcase its capabilities in transit vehicles, a MaxxForce-powered E-Z Rider II was on display at this year’s BusCon Expo, Chicago, Sept. 13-14, and will be again at the American Public Transportation Association’s EXPO 2011 show, New Orleans, Oct. 3-5.
