Updated February 2012 Freightliner Natural Gas Product Overview 2/10/2012

Daimler Trucks North America 2 Whats Driving Natural Gas? Improving operating economics vs. diesel Increasing diesel fuel costs driving quick NG payback Reduced after-treatment complexities Reduced GHG Emissions; 20% Average Noise reduction- Ten db reduction vs diesel Domestic Fuel/Energy Security Renewable Fuel

Daimler Trucks North America 3 Natural Gas Basics COMPRESSED NATURAL GAS Natural Gas that is compressed – typically to 3,600 psi – for dispensing and storage Gas is distributed through natural gas pipeline (the same infrastructure that delivers to homes and businesses currently) to the fuel location Gas is compressed at fuel location into CNG for dispensing into the truck Dispensing is similar to gasoline or diesel fuel The CNG is stored on the vehicle in one or more cylinders LIQUEFIED NATURAL GAS Natural Gas that is cryogenically cooled – to 260 o F – for dispensing and storage Gas is processed at LNG production and transported by special truck to the fuel location LNG is stored at fuel location in cryogenic tanks and dispensed directly into the truck Dispensing requires special safety equipment The LNG is stored on the vehicle in cryogenic tanks

Daimler Trucks North America 4 Natural Gas Basics COMPRESSED NATURAL GAS ADVANTAGES: Lowest price (compared to diesel & LNG) Lowest emissions Extensive infrastructure already exists Truck-Friendly technology CHALLENGES: Volume per energy content (requires more storage) Additional weight and OAL Range limits approximately 300 miles Performance of existing stations LIQUEFIED NATURAL GAS ADVANTAGES: Lower price than diesel Fastest Fill LNG is lower weight than CNG; allows greater storage and distance (current max of 400 miles) CHALLENGES: Infrastructure only exists in Southern California; SLC; and Connecticut, and Houston Venting; Performance Issues Higher production and distribution costs Truck cost for larger engine (15L) Shop Requirements

Daimler Trucks North America 5 Natural Gas Engine Technology Stoichiometric EGR engine (Example ISL G/ISX12 L) Uses high EGR rates in combustion process in place of excess air (Lean Burn). End result is an oxygen free exhaust allowing use of a simple 3 way catalyst Fuel Neutral- LNG and CNG Dual Fuel engine (Example Westport GX 15L) Uses diesel fuel as a pilot injection for Liquefied Natural Gas Due to the use of diesel fuel, exhaust requires emissions control devices (DPF, DOC, SCR) ONLY operates on LNG

Daimler Trucks North America How Safe is Natural Gas? Heavily regulated industry 20 year tank life TYPE III and IV Tanks, lightest weight Methane is lighter than air; will not pool under vehicle Drop/crash Testing Bonfire testing Dynamite testing Pistol/rifle testing – armor piercing bullets Google CNG Tank Testing – Numerous Web Sites and You Tube Videos SUMMARY: NATURAL GAS IS AS SAFE, OR SAFER, THAN DIESEL AND GASOLINE
