1 INTRODUCING CE SERIES WITH CUMMINS ISB6.7

2 OVERVIEW 1. Introducing the Cummins ISB Cummins ISB6.7 Features, Technology and Enhancements 3. The CE Engine Portfolio

3 INTRODUCING THE CUMMINS ISB6.7 What do you get when you take the industry s best selling medium-duty diesel engine and the most popular conventional-style bus over the past decade? A product that raises the bar. A time-tested design that features the Cummins SCR after-treatment system, the CE Series with Cummins ISB6.7 will offer the durability and uptime you demand while meeting EPA 2010 emissions. As Cummins ISB6.7 joins an engine line-up that includes the MaxxForce 7 and DT, IC Bus now offers the widest choice of diesel powertrain options in the bus industry.

4 BLUE DIAMOND JOINT VENTURE Through our Blue Diamond JV, Navistar has extensive experience designing and building trucks with the Cummins ISB6.7 Engine. The Ford F650/750 Trucks, for which we have built over 20,000 units, share a common chassis with the Navistar DuraStar truck Model. This experience has enabled us to minimize the amount of time it took to bring the ISB6.7 to market in the CE Series Bus. Customer s can feel confident that quality and performance will be top notch at Job 1. These trucks are surpassing warranty and quality objectives and we expect the same results with the CE Series.

5 CUMMINS ISB6.7 FEATURES, TECHNOLOGY & ENHANCEMENTS

6 MAJOR FEATURES VGT Turbocharger The patented design is widely recognized as the industry leader for performance. Electric actuation improves precision and responsiveness. The VGT Turbocharger also increases fuel economy and braking horsepower. High Pressure Common Rail (HPCR) Higher injection pressures produce quick throttle response at every rpm. Optimized timing increases fuel efficiency, lowers emissions and enables smoother, quieter operation. Single High-Capacity Electronic Control Module (ECM) A single ECM manages the engine and aftertreatment system for optimum performance and fuel efficiency. Cummins SCR Aftertreatment System Proprietary system consists of a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) technology for near-zero emissions.

7 FUEL ECONOMY The 2013 ISB6.7 gets some of the best fuel economy of any engine in its class. In 2013, the ISB6.7 gets up to 2 percent better fuel economy versus the 2012 model. The addition of an air-intake throttle makes the Exhaust Gas Recirculation (EGR) system more efficient, to increase fuel economy and lower operating costs.

8 2013 ENHANCEMENTS Better Fuel Economy 2013 certification meeting the 2014 fuel efficiency and greenhouse gas standards Reduction in parasitic losses Better Reliability Continuous improvement NanoNet filter Better Customer Support Additional components covered with new Extended Coverage plans

9 BETTER RELIABILITY A new ECM for the 2013 product controls the DEF Dosing Valve and helps improve the overall efficiency and reliability of the Cummins Aftertreatment System. The VGT Turbocharger, EGR Crossover Tube and EGR Valve Orientation have all been on engine improvements. The VGT Turbocharger s actuator has been improved, the actuator controls the Variable Geometry portion of the Turbocharger. Improving the actuator leads to reliability and efficiency improvements for the ISB6.7. Another area of improvement of the ISB6.7 has been with the EGR. The Crossover Tube allows for easier installation for the OEMS and assists with the EGR flow. The Valve and Valve orientation also assists with OEM installation and has an internal seal that prevents water leaking into the EGR Cooler.

10 BETTER RELIABILITY EGR Crossover Tube And EGR Valve Orientation ECM There has also been an EGR Crossover Tube routing change which has lead to improvements in EGR reliability. The Valve orientation change switched from a vertical valve to a horizontal valve. There is also an addition of an internal seal to protect against water intrusion. The New ECM 2350 incorporates all changes needed to meet the 2013 OBD requirements. The ECM 2350 incorporates the DEF Doser Valve controls which helps improve the reliability of the Cummins Aftertreatment System.

11 BETTER RELIABILITY VGT Turbocharger Improvements to the actuator, which controls the VG section of the Turbo, leads to improved reliability.
