ORLANDO, Fla. (Jan. 21, 2013) – Cummins Inc. (NYSE: CMI) announced today its 2013 engine lineup for the market at the United Motorcoach Association (UMA) Expo in Orlando. The Cummins ISL9 and ISX12 clean-diesel engines meet the 2013 U.S. Environmental Protection Agency (EPA) regulations as well as the 2014 U.S. Department of Transportation (DOT) greenhouse gas (GHG) and fuel-efficiency standards, achieving fuel-economy improvements for motorcoach customers. The engines will be on display at the UMA Expo on Jan. 20-24.

Both engines will offer customers up to 2 percent better fuel economy compared with the 2012 model-year engines while also delivering improved reliability. A more efficient fuel pump and water pump on the ISX12, as well as enhancements to the VGT™ Turbocharger on the ISL9, help reduce overall parasitic loss, resulting in increased fuel efficiency.

“Cummins is committed to delivering fuel-efficient, reliable engines designed to meet the needs of our customers, and we are doing so without any major hardware changes in 2013,” stated Chuck Goode, Cummins Account Executive – Motorcoach Business. “We are building upon industry-leading base engine continuous product improvements that will directly impact our customers’ bottom line.”

In 2013, the EPA regulations call for the same near-zero emissions levels relative to oxides of nitrogen (NOx) and particulate matter (PM), as regulated since 2010. Also included in the 2013 regulations are On-Board Diagnostics (OBD), which are required for the complete on-highway engine lineup. OBD monitors emissions-related engine systems and alerts drivers via an in-cab warning lamp, helping to provide early detection of any potential emissions-related malfunction. New regulations for 2014 from the EPA and the DOT will institute equivalent carbon dioxide (CO2) and fuel-efficiency standards for commercial vehicle engines. All Cummins on-highway engines are certified to meet both of these standards, providing customers with a single product launch in 2013.

The Cummins 2013 ISX12 will continue to deliver exceptional performance by offering motorcoach customers the strong pulling power and throttle response they have come to expect with Cummins. In addition to performance benefits, the ISX12 will also achieve up to 2 percent better fuel economy versus the 2012 model. Ratings for the ISX12 include 385 hp (287 kW) and 425 hp (317 kW), providing an optimal balance of performance and fuel economy. Engine and aftertreatment extended warranty options are available, ranging from 5 years/200,000 miles to 5 years/500,000 miles on the ISX12.

The 2013 ISL9, rated at 380 hp (283 kW), includes heavy-duty features such as replaceable wet liners, roller followers, by-pass oil filtration and targeted piston cooling, all designed to deliver a dependable engine built to meet the needs of motorcoach operations. The addition of an air intake throttle on the ISL9 leads to improved Exhaust Gas Recirculation (EGR) efficiency, delivering up to 2 percent better fuel economy compared with the previous model. There are extended warranty options available for the ISL9, ranging from 5 years/200,000 miles to 5 years/500,000 miles.

The 2013 Cummins engines feature proven technology including the XPI fuel system, VGT Turbocharger and the Cummins Aftertreatment System with Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR). These components, designed and developed in-house, work as a totally integrated system driven by a single Engine Control Module (ECM) that manages both the engine and the aftertreatment system for optimum performance and improved fuel economy. Cummins ISL9 and ISX12 are both Buy America-compliant engines manufactured in the United States.

Cummins Care will continue to provide motorcoach customers the same access to 24/7/365 customer support via 1-800-DIESELSTM (1-800-343-7357) for their Cummins engines. Built on Cummins strong commitment to customer support, Cummins Care provides a trusted information source for questions regarding the latest engine, aftertreatment and related technology. The Cummins Care team is prepared to assist customers with any operational questions such as fuel and oil specifications and maintenance intervals. In addition, customers will have access to the largest and most capable service network in the United States and Canada, with over 3,500 locations. Cummins Care representatives can assist customers with finding the nearest authorized and available service location, ensuring that the location can quickly meet the customers’ specific service requirements.

“Cummins continues to offer motorcoach customers a lineup of fuel-efficient and reliable engines, all backed by exceptional customer support,” stated Goode. “This, along with meeting the 2014 GHG and fuel-efficiency standards a full year early, demonstrates our commitment to the motorcoach industry while being better where it counts for our customers.”
