(from Daimler Press
Release) Mercedes-Benz is set to launch a completely new
diesel engine generation starting in the autumn of 2008. For its
world premiere, the Stuttgart-based car manufacturer will unveil a
C-Class model with this new four-cylinder engine. In the C 250 CDI
BlueEFFICIENCY Prime Edition, this engine produces, with its 2.2
litres of displacement, 150 kW / 204 hp and 500 Nm of torque. The
premiere model can accelerate from a standstill to 100 km/h in just
7.0 seconds, on the way to its top speed of 250 km/h.
Notwithstanding these exceptional performance figures, the Prime
Edition only consumes an average of 5.2 litres of fuel per 100 km (NEDC),
with CO2 emissions of 138 g/km. The engine impresses with its eager
responsiveness and smoothness of operation, which can make it a
sensible alternative to the higher-displacement six-cylinder engines
in future.
The Mercedes-Benz
C-Class is a great favourite with the public. Since its official
market launch on March 31 2007, over 400,000 buyers have opted for a
saloon or an estate from this model series. As a result of this, the
C-Class has maintained its position as world-wide market leader in
its segment. The new C 250 CDI BlueEFFICIENCY Prime Edition adds a
further highlight to this successful model series which has already
received numerous distinctions. With the new diesel engine, which
celebrates its world premiere in this model, Mercedes-Benz shows
that frugal consumption and high output - and with them both
environmentally-friendly driving and driving pleasure - can be
mutually compatible.
Exemplary figures in terms of
power output, consumption and emission characteristics
A displacement of 2143
cc, 150 kW / 204 hp, and 500 Nm of torque - these are the engine's
key figures. Figures that place this newly-developed four-cylinder
diesel engine in the top position among the diesel engines of its
class. At the same time, in the C 250 CDIBlueEFFICIENCY Prime
Edition, the engine consumes on average just 5.2 litres of fuel per
hundred kilometres (NEDC), a value achieved by no other comparable
motor car.
Apart from exceptional
power output figures, the new powerplant offers significantly
improved torque build-up from low engine speeds, compared to its
predecessor model. The benefit of this is that in everyday driving
situations it enables low-consumption driving at low engine speeds.
In addition, the new engine will assume market leadership in terms
of untreated exhaust emissions. Already today, it complies with the
future EU5 emissions standards and, beyond that, has the potential
to comply with the EU6 and BIN5 standards as well.
Exemplary figures in
terms of power output, consumption and emission characteristics are
achieved by the new engine thanks to the implementation of a whole
package of innovative technologies. This includes among other
things:
--a maximum ignition
pressure of 200 bar,
--fourth-generation common-rail technology with a rail pressure
increased by 400 bar to 2000 bar, as well as a new piezo-injector
concept with direct nozzle needle control for greater
flexibility in injection timing, leading to smoother running of
the engine,
--larger, variable oil spray nozzles and variable water pump,
--dual-stage supercharging.
Another design
innovation is the camshaft drive positioned at the rear. This way,
with a north-south installation design and engine bonnet rising
towards the rear, it is possible to comply even better with
pedestrian protection regulations.
A promising future for the new
four-cylinder diesel engine
For an engine of its
displacement, it is exceptionally compact, so that it can be fitted
in different installation spaces. Beginning in 2008, this new
four-cylinder diesel engine will replace four of the existing diesel
engines at Mercedes-Benz. It can be installed either lengthways or
crossways in various model series, and several power rating variants
will be available. Apart from the C-Class, the engine will also be
installed in the E-Class, in the new GLK-Class and in the future
E‑Class Coup. With its impressive output figures, the new engine
will replace higher-displacement engines in heavier vehicles, where
it will be able to reduce consumption effectively through this
"downsizing".
Ingenious fine detail work reduces
consumption
In the Mercedes-Benz C
250 CDI BlueEFFICIENCY Prime Edition the new diesel engine is
combined with a sporty six-speed manual transmission with overdrive.
This, too, contributes to the great efficiency of the model.
Furthermore, Mercedes-Benz engineers have drawn up an additional
package of measures in order to achieve the most exceptional
consumption figures. The package includes among other things:
-- aerodynamic
finishing touches, with particularly airflow-enhancing
exterior-mirror housings as well as smooth underbody cladding;
-- newly developed tyres that reduce rolling resistance by 10
percent;
-- an efficient energy-management system with adaptive power
steering, which with the help of an additional valve, closes the
flow of the power-steering pump when it is not required.
Useful information: new gearshift
and consumption display on dashboard
Experience from
Mercedes-Benz eco-training shows that the driver, too, can save fuel
by adopting an energy-conscious style of driving - and also do that
without compromising driving pleasure. In the C 250 CDI
BlueEFFICIENCY Prime Edition a newly-developed gearshift display on
the dashboard assists the driver by informing him of the best moment
to shift gear in order to save fuel. In addition to this gearshift
recommendation, the instrument cluster shows the precise current
fuel consumption.
Sporty genes, state-of-the-art
engineering, extensive equipment and appointments
The basis of the new C
250 CDIBlueEFFICIENCY Prime Edition is the C-Class Saloon of the
AVANTGARDE equipment line, in which the sporting genes of the
Mercedes-Benz brand come particularly to the fore, most noticeably
in the radiator grille with its distinctive louvres and the large,
centrally positioned Mercedes star. Among car connoisseurs this
design element has been seen, for a long time, as a typical badge of
the sportier Mercedes models. Now, in the AVANTGARDE models of the
C-Class for the first time the star graces a saloon, as an
unmistakable expression of the vehicle's inherent strengths:
agility, power and performance, without at the same time neglecting
other time-tested C-Class attributes such as safety and
long-distance comfort. Aluminium interior trim (optional: birds-eye
maple) and other stylish details accentuate the sporty, effortlessly
superior appearance of this model.
The C 250 CDI
BlueEFFICIENCY Prime Edition is equipped with 16-inch light-alloy
wheels and 205/55 R16 tyres as standard - in addition to this,
16-inch light-alloy wheels in sporty 7-spoke design (likewise 205/55
R16 tyres) and 17-inch light-alloy wheels in 5-twin-spoke design
with wide-base tyres (225/45 R17 at front, 205/40 R17 at rear) are
available as no-cost options.
Naturally, all the
pioneering technical systems of the C-Class are on board as well:
for instance, the AGILITY CONTROL package with situation-responsive
shock absorber control, the Intelligent Light System with five
different lighting functions and the PRE-SAFE anticipatory occupant
protection system.
The extensive standard
equipment also includes the Audio 20 infotainment system. This
features, among other things, a keypad to enter telephone numbers
and radio frequencies, as well as a Bluetooth interface that
connects the mobile phone wirelessly with the hands-free feature.
Floormats with the lettering "Prime Edition" draw attention to the
special status of the new model.
Prime Edition limited to 5000 units
The C 250 CDI
BlueEFFICIENCY Prime Edition model can be delivered in obsidian
black, palladium silver or iridium silver. It is also optionally
available in the special paint finish diamond white metallic. The
sporty appearance can be emphasised even more forcefully with the
optional AMG sports package, which includes distinctively-styled
front and rear aprons as well as side skirts.
Production of the C 250
CDI BlueEFFICIENCY Prime Edition is limited to 5000 units. It is a
consummate performer in terms of its sportiness, environmental
protection and economic efficiency. Its price (including VAT) is
40,638.50 euros.
