Confirmed in a road test: The new Actros is even more economical and significantly cleaner than its well-known and economical predecessor.
engine weight, low friction and ancillary components that
are switched on as needed, the main improvement is the emphasis
on low-end torque, with the resultant benefits of high
torque at low engine speeds. In addition, the ECO start-stop
function is included as standard equipment.
These fuel-efficient four-cylinder gasoline engines are initially
being used in the new models of the compact class, for which
we also offer a new four-cylinder diesel engine – the latest
version of an engine with third-generation common-rail direct
fuel injection. Supported by the new transmissions – the
7G-DCT dual clutch transmission and the new six-speed manual
transmission – the two diesel models of the B-Class (the
B 180 CDI BlueEFFICIENCY and the B 200 CDI BlueEFFICIENCY)
consume only 4.4 liters per 100 kilometers; this represents
CO 2 emissions of 114 g/km.
Even cleaner and more efficient: the new Actros. In recent
years, we have also continually reduced the fuel consumption
and emissions of our heavy-duty commercial vehicles. We
managed this thanks to even more efficient engines and improvements
in tires and aerodynamics, as well as an axle drive ratio
in line with the vehicle’s requirements. Our BLUETEC technology
also made a major contribution to this development. Its
market success is reflected in the sales figures: In the year under
review, we sold more than 155,000 trucks with BLUETEC
technology worldwide.
The new Actros is the world’s first truck to be systematically
designed to meet the future Euro VI emission limits. At the
same time, reducing fuel consumption was a significant design
requirement for this new heavy-duty truck, in spite of its
sophisticated exhaust cleaning system. Its predecessor model,
the Mercedes-Benz Actros 1844 LS, already holds the record
for being the world’s most fuel-efficient series-produced truck.
In a comparative test drive, two new Actros 1845 trucks
and an Actros 1844 from the predecessor series each covered
10,000 kilometers on the route from Rotterdam to Szczecin
and back. During the round trip, the Actros 1845 BlueTec 6 (Euro
VI emissions limit) returned fuel consumption of 25.9 l/100 km,
which is 4.5% less than its predecessor. The Actros BlueTec 5
(Euro V emissions limit) consumed 25.1 l/100 km, or 7.6%
less than the reference figure. This means that the new Actros
is approaching fuel consumption of only 1 l/100 km per
ton of payload.
Our goal for the total Daimler truck fleet in Europe is to reduce
fuel consumption by an average of 20% per ton-kilometer
by 2020. To achieve this goal, we continue to work hard on
the development of technical innovations.
Hybrid trucks in daily use. Hybrid technologies result in
significant fuel savings. This is demonstrated by the results
achieved in the United States and Japan, where a large
number of hybrid buses and trucks from Daimler’s Orion, Freightliner
and Fuso brands are now being operated by customers.
The Fuso Canter Eco Hybrid’s fuel consumption is about 20%
lower than that of a vehicle with a comparable diesel engine.
The vehicle achieves this improvement by continually adjusting
its operating mode to match the current driving situation. The
electric motor is used to get the truck moving and the diesel
engine kicks in during rapid acceleration. The engine also
provides the driving power when the vehicle is moving along at
a steady pace. About 1,200 Canter Eco Hybrid trucks are in
use today all over the world. The Freightliner M2 e Hybrid truck
is equipped with a hybrid electric drivetrain system and utilizes
the electric part of the powertrain also for quiet and zeroemission
operation of the ancillary components. As a result,
the hybrid truck consumes up to 30% less fuel than the conventional
diesel-powered M2 106 model. Around 600 Freightliner
hybrid trucks have already been delivered to customers. The
Mercedes-Benz Atego BlueTec Hybrid combines a fourcylinder
diesel engine that meets the EU’s Euro V emission
standards with an electric motor powered by high-performance
lithium-ion batteries. This makes it possible to reduce
fuel consumption and CO 2 emissions by 10 to 15%, with even
greater savings possible depending on topography and driving
conditions. Following successful tests of the first prototypes,
we have delivered a fleet of 50 Atego BlueTec hybrid trucks to
German customers since the beginning of 2011.
Hybrid buses in local public transportation. Various hybrid
bus models from Daimler are already returning significantly
lower fuel consumption and CO 2 emissions in local public transportation.
More than 3,200 Orion VII buses with diesel-electric
hybrid drive are already in operation in North America. The
Orion’s hybrid drive system reduces fuel consumption by up
to 25% compared with conventional buses in regular service.
A hybrid version of a school bus from Thomas Built Buses, the
Saf-T-Liner ® C2 Hybrid, has been available in North America
since 2009. Similarly to heavy-duty vans and trucks from
Freightliner, vehicles from Thomas Built Buses use a parallel
hybrid system. The Mercedes-Benz Citaro G BlueTec Hybrid
