Latest Mercedes-Benz diesel technology with NOx emissions significantly below certification
limits

Stuttgart, Germany, 08 May 2018 - With the market launch of the new A-Class, the new diesel
engines from Mercedes-Benz are now available from the compact class to the luxury class. With
these engines, Mercedes-Benz vehicles achieve average nitrogen-oxide (NOx) emissions of
between 40 and 60 milligrams per kilometer over many thousands of kilometers of driving on the
road under the conditions of the Real Driving Emissions (RDE) measuring method. These
emissions are significantly below the RDE limit of 168 milligrams per kilometer. This is made
possible by an innovative package of combining engine and exhaust-gas aftertreatment, which
has been introduced consistently over the past two years as part of the new generation of engines
and is continuously being developed further.

Following the launch of the new generation of diesel engines in the E-Class (four-cylinder OM
654) and the S-Class (six-cylinder OM 656), the four-cylinder OM 608 is being introduced in
May in the new A-Class A 180 d (fuel consumption combined: 4,5-4,1 l/100 km combined CO2
emissions: 118-108 g/km). The new diesel engines from Mercedes-Benz are therefore now
available from the compact class to the large, luxury class. As is already the case with the OM
654 and OM 656, the OM 608 engine features a compact exhaust-gas aftertreatment system close
to the engine as well as multiple exhaust gas recirculation (EGR) with high- and low-pressure
EGR, which ensures that average nitrogen-oxide emissions are significantly below the current
legal limits of the new RDE test method. For the first time, this model series also features an
SCR catalyst with AdBlue exhaust fluid. Mercedes-Benz now offers this technology in all
current vehicle classes.

In the coming months, many more Mercedes-Benz models will be launched that are certified in
accordance with Euro 6d-TEMP. By September 2018, more than 30 of the currently available
models and more than 200 variants are to be changed over to Euro 6d-TEMP Norm.

a full year before this is mandatory for all vehicles. Mercedes-Benz customers will therefore
have an ever increasing range of such vehicles to choose from in the coming months.

“Mercedes-Benz’s new generation of engines already demonstrated two years ago, how the
NOx-challenge in Diesel cars can be solved technically. We are fully committed to modern diesel
engines as part of the drive mix for the future,” said Ola Källenius, Member of the Board of
Management of Daimler AG, responsible for Group Research and Mercedes-Benz Cars
Development.

Current Mercedes-Benz vehicles equipped with the latest diesel technology can achieve NOx
emissions in a very low double-digit and sometimes even single-digit range in some RDE-
measurements on the road. For instance, the technical inspection company TÜV Hessen tested a
wagon version of the new C-Class with a new 1.6-liter four-cylinder OM 654 engine according
to the currently applicable RDE regulations, and measured nitrogen-oxide emissions below 10
milligrams per kilometer in the overall cycle, both with and without cold starts. When a sedan
version of the new C-Class with the same engine was tested in accordance with the RDE method,
NOx emissions of approximately 10 milligrams per kilometer were measured.
However, average emissions over many thousands of kilometers under different conditions are
much more meaningful than individual measurements. Mercedes-Benz diesel engines of the new
generation (OM 654, OM 656 and OM 608) already achieve average NOx emissions of about 40
to 60 milligrams per kilometer on RDE journeys – also in city traffic. These NOx emissions are
thus well below the current RDE limit of 168 mg/km and even below the laboratory limit of 80
mg/km. Organizations such as, for example, Dekra, TÜV or auto magazines have confirmed that
very good results are achieved in road tests.

Electric cars:

Mercedes is to open its sixth battery factory in 2018, which makes it a tough competitor to Tesla,
Inc. The six factories will be established across 3 continents.

The brand has also planned to launch its electric EQ brand with the EQC SUV being set for
production in the year 2019. In September 2018, Mercedes unveiled the EQC, its first fully
electric car, at an event in Stockholm.

2022 will be the year in which Daimler has said that the company will have invested $11 billion
to ensure that every Mercedes-Benz has a fully electric or hybrid version available on the market.

While releasing details of the project, Markus Schäfer said,

"Our electric vehicles will be built in six plants on three continents. We address every market
segment: from the smart fortwo seater, to the large SUV. The battery is the key component of e-
mobility. As batteries are the heart of our electric vehicles we put a great emphasis on building
them in our own factories. With our global battery network we are in an excellent position: As
we are close to our vehicle plants we can ensure the optimal supply of production. In case of a
short-term high demand in another part of the world our battery factories are also well prepared
for export. The electric initiative of Mercedes-Benz Cars is right on track. There global
production network is ready for e-mobility.electrifying the future
A Model of Mercedes benz:

Currently this company produces a wide range of advanced luxury cars, trucks and buses in its
manufacturing facilities, based all over the world besides Germany.Mercedes-Benz is a German
manufacturer of automobiles, buses, coaches, and trucks. It is currently a division of the parent
company, Daimler AG(formerly DaimlerChrysler AG), after previously being owned by
Daimler-Benz.

Mercedes-Benz has its origins in Karl Benz's creation of the first automobile in January 1886,and
by Gottlieb Daimler and engineer Wilhelm Maybach's conversion of a carriage by the addition of
a petrol engine the same year.

The Mercedes automobile was first marketed in 1901. The first Mercedes-Benzida brand name
vehicles were produced in 1926, following the merger of Karl Benz's and Gottlieb Daimler's
companies into the Daimler-Benz company.Mercedes-Benz has introduced many technological
and safety innovations that have become common in other vehicles several years later.

F125 concept:

With its four powerful, wheel-mounted electric motors the Mercedes-Benz F 125! Research
Vehicle is a particularly dynamic demonstration of the principle “fascination and responsibility”.
Thanks to very generous performance reserves it copes effortlessly with any traffic situation –
with no emissions whatsoever.

With its electric drive system based on highly advanced Mercedes-Benz fuel cell technology, the
F 125! ensures particularly satisfying and sustained driving pleasure. The electric power for the
motors is generated on board by a chemical reaction between hydrogen and oxygen, or obtained
from the efficient recuperation of braking energy. The only emission resulting from the chemical
reaction is pure water vapour. Total operating range is at the same level as a modern diesel car.
The high performance potential of the electric drive components in the F 125! once again
demonstrate the versatility of the highly scalable, modular E-Drive system from Mercedes-Benz.

Intelligently conceived vehicle architecture

In the new Mercedes-Benz research vehicle, the fuel cell stack is centrally located under the
bonnet at the front, while the compact electric motors are installed near the wheels in the front
and rear axle areas. The composite hydrogen reservoir in the area of the centre tunnel, between
the front seats and the floor assembly, has a capacity of around 7.5 kilograms and is ideally
protected against the consequences of accidents.

Metal oir of the fuorganic Frameworks: the hydrogen reservture

Metal Organic Frameworks (MOFs) are porous solid bodies which consist of numerous, always
identical basic components and can be very variably put together on a modular basis. They are
made up of nodal points known as Structural Building Units (SBUs). The connecting elements
between these nodal points are formed by organic molecules known as Linkers. This structural
principle allows solid bodies with extremely large specific surface areas, which in turn provides
the basis for an enormous hydrogen storage capacity.

High storage capacity with low volume and great flexibility

Gigantic “inner” surfaces of up to 10,000 sq. m. per gram – the current status of research – make
MOFs attractive for numerous applications: they are suitable as gas cleaners for fuel cells, for
example, and also – as envisaged for the F125! – as a storage medium for gases, in this case
hydrogen. MOFs can be used as pressurised containers (30-80 bar), but for a higher storage
density also as low temperature tanks at 77 K (around -196 degrees Celsius), i.e. considerably
above the 20 K boiling point of hydrogen. These attributes and the fundamental variability of the
MOF’s shape allow an installation position suited to the vehicle requirements. This means that
future MOFs can be flexibly installed in the body structure. Key advantages of this solution:

Less installation space thanks to better adaptability means more scope for packaging and more
room for the occupants.

The low installed position is conducive to a low centre of gravity, with a positive effect on
handling and driving dynamics.

Full integration into the bodyshell structure ensures the best possible crash and operating safety.

Lithium-sulphur battery with a high energy density

The lithium-sulphur battery installed behind the rear seats has a storage capacity of 10 kWh. It
can be inductively charged at “intelligent” charging stations, and the convenient charging process
can be monitored and controlled using a smartphone. The principal advantage of lithium-sulphur
technology, whose usability in vehicles still requires further research, is the high specific energy
density of the cells. Compared to current batteries this allows relatively compact but highly
efficient energy storage. When designing the F 125!, the developers worked on the assumption
that by the time of its introduction into series production, this battery type will be capable of
energy densities up to 350 Wh per kg. This would represent roughly a doubling of current
performance. The real potentials of this technology are however the subject of basic research,
and are still difficult to assess at present.

All in all, the F 125! Represents a further, important step towards the market maturity of a fuel
cell powered car in the luxury class. With this research vehicle, Mercedes-Benz is demonstrating
completely new future ways to design large and luxurious automobiles that are marketable,
environmentally friendly and socially compatible.

Touring saloon with sports car genes

The use of four electric motors has a number of advantages in terms of driving dynamics.
Mercedes-Benz has already delivered an impressive demonstration of the performance potential
residing in this e4MATIC design with the battery electric SLS AMG E-CELL super sports car,
whose rear-end module was developed further for the F 125!. The new front axle design provides
a visionary outlook on the integration of electric drive systems into the front axle. The chosen
positioning of the drive components allows optimal weight distribution, and also – thanks to
active torque vectoring – the need-related assignment of power to each individual wheel.

Apart from ensuring optimal traction at all times, the electronic all-wheel drive with its wheel-
specific yaw-damping improves handling stability at high speeds. During brisk cornering,
however, wheel-specific intervention allows a metered increase in the yaw rate with an improved
steering response and less steering effort. This drive configuration also allows highly efficient
energy recuperation at each wheel, cross-wind stabilisation, avoidance of load-change responses
and therefore even more controllable handling when cornering, without the need for ASR
(acceleration skid control) intervention.

Ride comfort at the highest level

110 years after the invention of the modern passenger car, the Mercedes Simplex of 1901,
Mercedes-Benz is once again presenting a trailblazing, visionary vehicle concept – this time in
the form of a sporty and comfortable touring saloon with an emission-free F-CELL Plug-in
HYBRID system. The concept anticipates future technological trends, with a vehicle architecture
to suit.

The F 125! is the first electric car to feature an air suspension and continuous damper
adjustment. The result is an optimal balance between ride comfort, driving dynamics and use of
energy. The system also allows the vehicle’s suspension height to be adjusted as a function of
speed and vehicle status – to improve the aerodynamics at fast motorway speeds.

Optimal traction and driving dynamics are ensured by active torque vectoring at the front and
rear axles. The singlestage gears at the front and rear axles accelerate the vehicle comfortably
and without interruptions in tractive power, right up to the top speed. One technical highlight of
the suspension system is special compensation of drive moments in the front axle, which almost
entirely eliminates drive and recuperation influences on the steering, and noticeably reduces
pitching.

Comparision between BMW and AUDI:

The gap between Audi and BMW is minimal, but Mercedes comes out much cheaper. Mercedes
was 24% cheaper than Audi and 20% cheaper than BMW. This could point to the emergence of
Audi and BMW becoming the front-runners in the luxury car market and that brand power now
coming into play in the aftermarket.

Brakes and Exhausts are similarly priced as are Servicing and MOT:

If you change your car fairly regularly then you most likely will not be paying over the odds to
maintain your Audi as routine work does not differ in price by much. Audi are in fact cheapest
for Steering and Suspension work and Electrical and Batteries. In comparison Mercedes are the
most expensive for Electrical and Batteries work, 17% more expensive than Audi.
There is in general a decrease in repair costs after year 8 for both BMW and Mercedes. This is
expected for a number of reasons:
They cover fewer miles They may be more mechanically simple, requiring less labour time
during the repair Owners are often more willing to ‘live with’ certain faults or imperfections for
longer, or are more likely to turn to non-OEM parts (or even reconditioned ones.)

So it is interesting that Audi repairs don’t drop off and are consistently more expensive. Maybe
Audi drivers take more pride in their vehicles and ensure to maintain them for longer.
Conclusion:

In the present study of mercedes-benz F125 hydrogen vehicle i have learn in detail AMG hybrid
technology and aerofoil design of vehicle overview and comparision regarding economy in
maintanence and human safety, prevention of road accidents with aid of all human interference
