Daimler Trucks North America has announced the launch of the Freightliner Cascadia Evolution, a new heavy-duty truck that achieves up to 7% better fuel efficiency compared to its predecessor, featuring advanced Detroit DD15 engines and aerodynamic improvements. A recent 2,400-mile test drive confirmed the truck's capabilities under real-world conditions, while compliance with the upcoming Greenhouse Gas 2014 regulations positions Daimler as a leading force in environmentally-friendly commercial vehicles. Additionally, a successful 2,700-mile test of a compressed natural gas truck demonstrates Daimler's commitment to alternative drive technologies and sustainable transportation solutions.

CO2 Milestone Reached in the U.S.:
Daimler Commercial Vehicles Impress
During Extensive Test Drive
• New Freightliner Cascadia Evolution:
Up to 7 percent less fuel consumption
• Daimler’s US truck brand Freightliner is leading in
terms of Greenhouse Gas 2014 (GHG14) regulations
• A glimpse of the future: Cascadia technology platform
reaches outstanding fuel consumption of 10.67 miles
per gallon (22 l/100 km)
• Successful long-distance test run with natural gas truck
Stuttgart / Washington D.C., U.S. – Daimler’s U.S. commercial vehicle
subsidiary Daimler Trucks North America (DTNA) once again demonstrates
its innovative strength in the field of environmentally friendly technologies:
In Washington D.C. – in the presence of U.S. government representatives
and the U.S. Secretary of Transportation Ray LaHood – DTNA CEO Martin
Daum presented the new heavy-duty truck Freightliner Cascadia Evolution,
which will become available on the U.S. market starting next year. When
compared to the current model (EPA 10 Cascadia), the new truck consumes
up to 7 percent less fuel.
These fuel savings were confirmed by an independent agency (Automotive
Testing and Development Services) in the course of a one-week drive across
the U.S. under real-life conditions. The 2,400-mile (almost 4,000 km) route
led from San Diego, California, to Gastonia, North Carolina. During the test,

2. the two heavy-duty semitrailer trucks – weighing approximately 34 tons or Page 2
76,000 lbs. each – traveled at an average speed of 62 mph (around 100
km/h).
According to Martin Daum, two key factors led to the positive result of this
Evolution of Efficiency Tour: “The tremendous fuel savings of the new
Freightliner Cascadia are primarily due to the new Detroit DD15 engine as
well as the aerodynamic measures. The fuel efficiency drive was a unique
opportunity for us to conduct a test under real-life conditions of our latest
technologies and the tremendous fuel saving potential they offer to our
customers.”
The DD15 engine of the Detroit brand, which is part of Daimler, is a
turbocharged inline six-cylinder engine with 14.6 liters of displacement. As
with all Detroit engines, it is equipped with Daimler BlueTec technology,
which reduces emissions to near-zero levels and even falls below the EPA 10
emissions standard for the NAFTA region (comparable to Euro VI).
Freightliner trucks comply with Greenhouse Gas 2014 regulations
Already at the beginning of this year, the Environmental Protection Agency
(EPA) certified the Daimler commercial vehicles subsidiary’s complete
portfolio of long-distance trucks, medium-duty trucks, and vocational
vehicles of the Freightliner and Western Star brands as fully compliant
with the Greenhouse Gas 2014 (GHG14) regulations.
This means that DTNA is leading in the U.S. commercial vehicles industry.
The company already meets the standards set by the EPA and the National
Highway Traffic Safety Administration (NHTSA), which will not go into effect
until the beginning of 2014. These regulations aim to permanently reduce

3. the green-house gas emissions of heavy- and medium-duty trucks. The EPA Page 3
believes that through the new GHG14 regulations, trucks and buses of the
model years 2014 through 2018 are projected to reduce oil consumption by
530 million barrels and greenhouse gas emissions by 270 million metric
tons.
A glimpse of the future: Freightliner Cascadia technology
carrier measured with 10.67 miles per gallon
During a test drive with a technology carrier at the proving grounds in
Uvalde, Texas, DTNA demonstrated that the fuel consumption of a heavy-
duty semitrailer truck can be reduced even further through ideal airflow
and additional technical fine-tuning.
For the test drive, the new Freightliner Cascadia Evolution was equipped
with a Detroit DT12 automated transmission, low rolling-resistance wide-
base tires, and a trailer specifically designed by DTNA with aerodynamic
aspects in mind. This technically and aerodynamically optimized
combination of a tractor and a trailer (total weight: approximately 34 tons)
traveled exactly 1,000 miles at an average speed of 60 mph (97 km/h). The
resulting fuel consumption was 10.67 miles per gallon, or approximately 22
liters per 100 km.
Shaping Future Transportation: 2,700-mile test run with CNG truck
DTNA presented another impressive test result in the area of alternative
drive systems. For the first time, a natural gas-fueled Freightliner Cascadia
completed a tour from San Diego to Washington D.C. (approximately 2,700
miles), interrupted only by refueling stops every 350 to 500 miles. The CNG
truck (CNG = compressed natural gas) only used public gas stations to

4. refuel, thus impressively demonstrating that alternative drive technologies Page 4
represent a real alternative even today. In light of this success, Daum
promised that DTNA will keep pushing forward in the field of alternative
drive systems and continue to cooperate closely with government agencies
and form strategic alliances with other economic sectors. “We want to live
up to our leadership position by promoting environmentally friendly,
resource-conserving, and sustainable transportation solutions,” he said.
Daimler Trucks and Daimler Buses have been pressing ahead with the
development of environmentally friendly technologies since 2007. The
leading commercial vehicle manufacturer consolidates these activities in its
worldwide “Shaping Future Transportation” initiative, which aims to turn the
zero-emission commercial vehicle of tomorrow into reality through efficient
and clean drive systems and alternative fuels. The initiative involves the
sparing use of resources and the reduction of emissions of every kind, while
guaranteeing maximum traffic safety.
