FOR IMMEDIATE RELEASE

CUMMINS RECEIVES FIRST EPA CERTIFICATION FOR MEETING 2014 GREENHOUSE GAS AND FUEL-EFFICIENCY RULES

COLUMBUS, Ind., (Oct. 1, 2012) - Cummins Inc. (NYSE: CMI) announced today that it has received certification for its ISX15 engine from the U.S. Environmental Protection Agency (EPA), meeting both the EPA 2013 regulations and the new greenhouse gas and fuel-efficiency rules that will take effect in 2014. Cummins 2014 greenhouse gas certification is the first engine certificate issued by the EPA.

Cummins ISX15, the top-selling engine in the heavy-duty truck market, will deliver higher levels of fuel efficiency and reliability in 2013. Efficiency improvements to the base engine include optimized combustion and reduced parasitic load through high-efficiency water, fuel and lube pump systems, and the ISX15 will achieve up to 2 percent fuel economy improvement over today's product. Cummins ISX15 for 2013 uses the same proven base engine with the XPI fuel system, VGT(TM) Turbocharger, Cummins Aftertreatment System with Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) technology, and fully integrated electronics.

"Cummins 2013 truck engines will deliver better fuel economy with no major hardware changes," said Jeff Jones, Cummins Vice President - Sales and Market Communications. "This results in improved reliability due to stable architecture.

"The certification of the ISX15 demonstrates Cummins commitment to deliver products that exceed both environmental and customer requirements. We are confident that we'll receive certification for our other on-highway engines well before the end of the year," Jones continued.

Cummins entire lineup of on-highway engines for truck, bus, RV and specialty-vehicle markets will enter production on Jan. 2, 2013. All engines are expected to be certified a full year early to the 2014 greenhouse gas and fuel-efficiency rules.

The EPA 2013 regulations require the same near-zero emission levels of oxides of nitrogen (NOx) and Particulate Matter (PM) as were required beginning in 2010. The new greenhouse gas and fuel-efficiency regulations will be required for all heavy-duty diesel and natural gas engines beginning in January 2014.

On-Board Diagnostics, which were introduced on the ISX15 in 2010, are also required across the full on-highway product line in 2013. On-Board Diagnostics will provide enhanced service capability with standardized diagnostic trouble codes, service tool interface, in-cab warning lamp and service information availability.

Cummins Care will be available for all EPA 2013 certified engines, including natural gas engines, and is available free of charge.
