Slide 2 BlueTEC Benefits - ALG, 04/29/08 The Diesel Trucks Same 3.0L DOHC 24-valve V6 CDI engine as in former diesel models + SCR Technology (AdBlue) The ML320 BlueTEC delivers impressive fuel economy, performance, and utility at an unmatched value - an excellent gasoline alternative. The R320 BlueTEC is the first clean diesel sports tourer, offering impressive fuel economy without sacrificing performance, utility, or space. 7,500 lb towing capacity 0 – 60 mph: 7.1 seconds The GL320 BlueTEC is the first luxury full size SUV with a diesel offering impressive fuel economy without sacrificing performance, towing capability and efficiency. 7,200 lb towing capacity 0 – 60 mph: 8.0 seconds 3,500 lb towing capacity 0 – 60 mph: 8.1 seconds 210 3,800 rpm 398 1,600 – 2,800 rpm 7-speed automatic transmission 4Matic permanent all wheel drive

Slide 3 BlueTEC Benefits - ALG, 04/29/08 Diesel Definitions M, R, & GL Class CDI E-Class BlueTEC (1) MY09 Future BlueTEC (2) Launch first in MY09 SUVs, followed by 212 E-Class Common-rail Direct Injection (CDI): Oxidizing Catalytic Converters Particulate Filter: DeNox Storage Catalytic Converter : AdBlue SCR Technology: Emissions:BIN 10BIN 8BIN 5 / LEV Availability:42 State40 State50 State DeNox earns E-Class BlueTEC Name AdBlue System provides 50 state availability

Slide 4 BlueTEC Benefits - ALG, 04/29/08 What is BlueTEC SCR (Selective Catalytic Reduction) AdBlue - injection Two different variants of BlueTEC NOx exhaust treatment technologies exist: ML320 BlueTEC R 320 BlueTEC GL320 BlueTEC E320 BlueTEC- System with DeNox Catalytic Converter (which current CDIs don’t have) 50 State-System (MY2009) 40 State-System (MY2009)

Slide 5 BlueTEC Benefits - ALG, 04/29/08 Clean enough to be 50 State AdBlue, a non-toxic additive is injected into exhaust stream Consequential large improvements in emission of: NOx = Nitrogen Oxide, which combines with hydrocarbons to create smog -> - 80% HC = Hydrocarbon, which is an organic compound consisting entirely of hydrogen and carbon - > - 61% CO = Carbon Monoxide, a colorless, odorless, poisonous gas -> - 34% PM = Particulate Matter, tiny particles of solid matter that lodge in the lungs and cause asthma - > - 88% AdBlue topped off at regular service intervals

Slide 6 BlueTEC Benefits - ALG, 04/29/08 Less Fuel Consumption:  Consumes 20-30% less fuel than comparable gasoline-powered vehicles  It offers fuel economy improvements in both city and highway driving  Results in less dependence of oil resources Less Emissions:  State of the art after-exhaust treatment system reduces NOx.  Lower fuel consumption translates to reduced Green house gas emissions. More Driving Fun:  Impressive torque, acceleration, and performance (incl. Towing capability)  Less engine noise and better insulation provides a quiet ride  Nonstop driving excitement up to 600 miles before refueling  Extremely Strong customer benefits for multiple target groups (“Save the planet”, “Fuel Prices/Cost of ownership”, “Energy independence”) BlueTEC Summary - Consumer Benefits
