The Mercedes-Benz A 45 AMG: Driving Performance for the new
generation
The A 45 AMG sees Mercedes-AMG embarking on a new era. For
the first time in the company's history extending back over more than 45 years,
Mercedes-Benz's performance brand is offering a fascinating high-performance
vehicle in the compact class. The A 45 AMG is representative of the "AMG
Performance 50" strategy for the future, which is to run up to the 50th
birthday of Mercedes-AMG GmbH in 2017. With a maximum output of 265 kW (360 hp)
and up to 450 Newton metres of torque, the AMG 2.0-litre four-cylinder turbo
engine is the most powerful series production four-cylinder engine in the
world.
The sensational power density of 133 kW (181 hp) outstrips even the most
powerful super sports cars. At the same time, the engine also boasts supreme efficiency
and complies with the EU6 emissions standard. The A 45 AMG also leads its
segment in terms of fuel consumption, running on 6.9 litres per 100 kilometres
in NEDC combined mode. These credentials indicate that a further
high-performing member of the BlueDIRECT family is now taking to the road. The
performance-oriented AMG 4MATIC all-wheel drive onboard the A 45 AMG sets new
standards in the car's segment.
The substance of the new Mercedes-Benz vehicle architecture
for front- and all-wheel drive provides the perfect basis for the A 45 AMG and
at least two other high-performance premium automobiles from Affalterbach.In
designing and developing the A 45 AMG, the experts at AMG have drawn on the
company's decades of experience in motorsport and the production of powerful,
high-performance vehicles. As such, the A 45 AMG will inherit the corporate DNA
and embody the AMG brand claim "Driving Performance" to perfection: a
fascinatingly sporty driving experience combined with impressive craftsmanship
and pronounced individuality.
"The A 45 AMG will enable Mercedes-AMG to appeal to new customers and tap new markets," observes Ola Källenius, Chairman of Mercedes-AMG GmbH. We are adding an extremely attractive model with exceptional performance data to our range of unique high-performance automobiles."
"With the new A 45 AMG we have well and truly achieved our aim of developing the most dynamic, powerful and efficient four-cylinder series production car," comments Tobias Moers, Head of Overall Vehicle Development and Board Member of Mercedes-AMG GmbH.With its impressive high-tech package and the performance-oriented AMG 4MATIC all-wheel drive, the A 45 AMG is a thoroughbred AMG through and through."
Dynamic and individual vehicle for new target group
Spanning the age range from 30 to mid-40, the target group
is younger than the AMG clientele to date. In successful careers and with an
independent frame of mind, these customers seek a dynamic and individual
vehicle.They wish to lend expression to their style- and trend-oriented way of
life with a car from a recognised high-performance brand. The A 45 AMG provides
the predominantly urban target group with an agile high-performance vehicle.
Mercedes-AMG accommodates their tech-savvy and individual outlook on life with
an extremely broad selection of optional equipment and appointments, colours
and materials.
Typically AMG: the most powerful series production
four-cylinder engine in the world
Two figures show that the A 45 AMG holds pole position in
its displacement segment:the newly developed AMG 2.0-litre turbo engine is the
most powerful series production four-cylinder turbo engine in the world. A
maximum output of 265 kW (360 hp) and up to 450 Newton metres of torque are
unmatched by any other mass-produced turbocharged four-cylinder engine
worldwide. The power density of 133 kW (181 hp) is also absolutely unrivalled.
In this discipline, the new AMG high-performance turbo engine even outstrips
the most powerful super sports cars.
The high power and torque output and the combination with
the performance-oriented AMG 4MATIC all-wheel drive as standard lead to
extremely dynamic performance: the A 45 AMG accelerates from zero to 100 km/h
in 4.6 seconds, while its top speed stands at 250 km/h (electronically
limited). The specially developed AMG engine is also a model of efficiency –
the A 45 AMG also leads its segment on this front, with fuel consumption of 6.9
litres per 100 kilometres in NEDC combined mode. This is accompanied by
particularly low exhaust emissions: the A 45 AMG already complies with the EU6
emissions standard which is not scheduled to enter into force until 2015,
combined with the limit for the particle count per kilometre of 6 x 1011 which
will be mandatory from 2017.

The basis for these impressive figures is provided by the high-tech package which has been put together by Mercedes-AMG. As a high-performance engine belonging to the BlueDIRECT family, the AMG 2.0-litre four-cylinder turbo engine features spray-guided direct petrol injection via piezo injectors positioned centrally in the four combustion chambers.
The
combination of multiple fuel injection and multiple spark ignition improves
fuel utilisation and increases thermodynamic efficiency substantially, leading
to lower exhaust emissions. Other highlights include the gravity-die sandcast
all-aluminium crankcase, weight-optimised crank assembly with forged steel
crankshaft and forged pistons with friction-optimised piston rings, NANOSLIDE cylinder
wall technology, air-water charge air cooling, generator management and ECO
start/stop function.
Twin-scroll turbocharger and AMG sports exhaust systemwith exhaust
flap Mercedes-AMG addresses the essential challenges concerning the response of
small-displacement turbo engines by means of a twin-scroll turbocharger,
maximum derestriction of the exhaust system and an innovative injection
strategy. The twin-scroll technology provides for a more spontaneous build-up
of charge pressure, making effective use of exhaust gas back pressure, exhaust
gas temperature and exhaust gas impulse. This results in a swifter build-up of
torque right from the lower rev range. As a positive side-effect, the
twin-scroll technology also benefits fuel consumption and exhaust emissions. At
a maximum charge pressure of 1.8 bar, the AMG 2.0-litre four-cylinder turbo
engine also leads the field in this respect.
The AMG sports exhaust system features large pipe
cross-sections and an automatically controlled exhaust flap. This technology,
which is familiar from the SLK 55 AMG, reconciles the two apparently
conflicting aims of tangible dynamism and hallmark Mercedes comfort on long
journeys. The flap is continuously adjusted by map control according to the
power called up by the driver, load status and engine speed. The two striking
tailpipes of the AMG sports exhaust system emit a fascinating, full engine
sound which is particularly impressive during powerful acceleration.
An AMG Performance exhaust system with exhaust flap and
featuring a dedicated tailpipe trim design is optionally available for the A 45
AMG. This provides for an even more emotional and striking engine sound when
the throttle is open and during gear shifting. The double-declutching function
during downshifting and the interruption of ignition and injection during
upshifting under full load produce a particularly throaty sound with the AMG
Performance exhaust system and create a level of emotionality which is
otherwise the reserve of engines with more than 4 cylinders.
Exterior design with sporty and muscular highlights
Mercedes-AMG adds emphatically sporty and muscular highlights
to the emotional exterior design of the new Mercedes-Benz A-Class sporting the
new dynamic style, sculptural character and feature lines on the sides. These
refinements ensure that the A 45 AMG looks the part as a distinctive
high-performance automobile – a genuine AMG through and through.
The front view of the A 45 AMG is characterised by the AMG
"twin blade" radiator grille and the cross strut in the AMG front
apron, both painted in matt titanium grey. Striking black flics surround the
large cooling air intakes at the sides. An interesting side view is guaranteed
by the AMG light-alloy wheels in twin-spoke design and the side sill panels
with inserts in matt titanium grey. The "TURBO AMG" lettering on the
wing is exclusive to the top model of the A-Class. The AMG rear apron with its
highlighted air outlet openings at the sides features a diffusor insert and
trim in matt titanium grey. Two square, chrome-plated tailpipes of the AMG
sports exhaust system with exhaust flap add an appropriately bold finishing
touch.
