The Mercedes-Benz A 45 AMG: Driving Performance for the new
generation
Affalterbach ? 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 system with 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.
High-performance cooling system with components from the SLS AMG
The high driving dynamics of the A 45 AMG call for a highly effective
cooling system. On the basis of the components belonging to the SLS
AMG, a low-temperature circuit is additionally deployed for air-water
charge air cooling of the four-cylinder turbo engine. The large cooler
section at the front level of the cooling module is supplemented by an
additional cooler in the wheel arch. Together with the charge air
cooler which is connected in series, a high-performance electric pump
ensures the required flow through the water coolers located behind the
large intake ports. This provides for ideal cooling of the highly
compressed charge air, thereby contributing towards optimum engine
performance.
Cooling of the transmission oil is integrated in the water cooling
circuit for the engine. The water cooler positioned behind the front
apron is supported by the heat exchanger which is fitted directly on
the transmission and supplied with cooling water as required by means
of an auxiliary pump.
Engine production ? a tradition of hand-built excellence
Similarly to all eight- and twelve-cylinder engines, the new AMG
2.0-litre four-cylinder turbo engine is also hand-built according to
the traditional AMG philosophy of "one man, one engine". An
exclusive assembly line has been set up for the new AMG engine at the
Mercedes-Benz engine production plant in Kölleda ? where all
BlueDIRECT four-cylinder engines are built for the A- and B-Class
models. A characteristic feature of the "one man, one
engine" production process is the AMG engine plate bearing the
signature of the responsible engine fitter. Apart from serving as an
AMG hallmark confirming superlative production quality, the AMG engine
plate also attests to the peerless DNA of Mercedes-Benz's
high-performance brand.
AMG SPEEDSHIFT DCT 7-speed sports transmission
Dual clutch transmission and all-wheel drive ? the drive package
onboard the new A 45 AMG is a demonstration of high-end engineering
prowess.The AMG SPEEDSHIFT DCT 7-speed sports transmission is directly
flange-mounted on the transversely installed AMG 2.0-litre
four-cylinder turbo engine. Key software modules have been adopted
from the SLS AMG super sports car with its inspirational power
transmission concept. The dual clutch transmission of the A45 features
seven gears, three driving programmes, a double-declutching function
and RACE START for optimum acceleration. The strengths of the AMG DCT
sports transmission include spontaneous gear shifting without any
interruption in tractive power, a tailor-made control strategy,
extremely smooth and easy gear shifting and a high level of
efficiency. Reinforced gear wheels provide for maximum stability.
Synchroniser rings with carbon-fibre friction linings improve
durability while also optimising the response time during manual
gear-changing ? the ideal basis for ambitious laps on cordoned-off
race tracks.
"Momentary M mode" for even greater dynamism and driving
enjoyment
Another special feature designed to enhance dynamic performance and
driving enjoyment is so-called "Momentary M mode". In C and
S mode, this enables the driver to activate manual mode
("M") without having to remove a hand from the steering
wheel, by pressing the "up" or "down" shift paddle
once. In Momentary M mode the driver experiences the dynamism and
performance of gear-shifting in manual mode in all of the automatic
driving programmes, with automatic up- and down-shifting into the
bargain. This allows the driver to devote his full attention to the
vehicle's impressive performance.
The shift times in manual mode "M" and in Sport mode
"S" are similarly sporty in character to those of the SLS
AMG GT super sports car.Briefly and precisely interrupting ignition
and injection under full load leads to even faster gearshifts with a
more emotional sound than ever. In "C" mode (Controlled
Efficiency), tangibly soft transmission and engine characteristics
support a fuel-efficient and comfort-oriented driving style. The ECO
start/stop function is also active in "C" mode.
Performance-oriented AMG 4MATIC all-wheel drive
The new A 45 AMG comes with variable, performance-oriented AMG 4MATIC
all-wheel drive as standard. In developing this all-wheel drive, the
focus firmly was on performance and dynamism. The power flux to the
rear powertrain is provided by a compact power take-off unit (PTU)
which is fully integrated in the 7-speed sports transmission. It does
not possess an oil circuit of its own. Instead, it is supplied with
lubricant from the oil circuit of the sports transmission . This
configuration gives rise to substantial weight advantages in
comparison to rival systems which branch off power by means of an
add-on component with its own oil circuit. Together with the
friction-minimised tapered roller bearings, the PTU achieves an
excellent level of efficiency. As an additional bonus, the system
weight of the new AMG 4MATIC all-wheel drive is up to 25 percent
lighter than the all-wheel drive versions offered by the competition.
A two-part propeller shaft transfers the power from the AMG 2.0-litre
four-cylinder turbo engine to the rear axle. In the interests of
favourable weight distribution, an electrohydraulically controlled
multi-disc clutch is integrated with the rear axle differential. The
multi-disc clutch immediately detects slip at the front axle. A
hydraulic pump instantaneously presses the discs together and channels
the engine torque to the rear wheels as necessary. All this takes
place virtually without the driver noticing. To enable particularly
fast response, the pump is always active and does not require to be
started up each time it is needed, such as is customary with other
systems. Power distribution is fully variable: in normal driving, the
A 45 AMG uses front-wheel drive in the interests of optimum
efficiency. When the driving dynamics so require, the variable AMG
4MATIC all-wheel drive splits the torque between front and rear axle
up to a ratio of 50 : 50 percent. The variables influencing the power
distribution ratio are vehicle speed, lateral and longitudinal
acceleration, steering angle, speed difference between the individual
wheels, selected gear and accelerator position.
3-stage ESP® with ESP® Curve Dynamic Assist
An exclusive feature is the interaction of the AMG 4MATIC all-wheel
drive with the 3-stage ESP® and the ESP® Curve Dynamic Assist. The
three ESP® stages enable the driver to vary the dynamics of the A 45
AMG according to his individual wishes at the push of a button. The
safety-oriented "ESP ON" mode supports the driver in
maintaining neutral handling characteristics. The system initiates
braking intervention on one or more wheels and reduces the engine
torque on detecting that the operating conditions are becoming
unstable.
Briefly pressing the ESP® button activates "ESP SPORT
Handling" mode. This dynamically oriented driving mode applies
appropriate control strategies for later ESP® intervention and
increased drive torque at the rear axle. This means more fun at the
wheel for drivers who are keen to exploit the vehicle's dynamic
potential. Pressing the ESP® button longer activates "ESP
OFF". In this mode, the ESP® functions are not available. ESP OFF
should only be used by experienced drivers on cordoned-off race
tracks. When the driver steps on the brake pedal in the course of
braking in "SPORT Handling" mode or "ESP OFF"
mode, all the safety functions of the ESP® system are restored.
ESP® Curve Dynamic Assist complements the ESP® system to perfection:
during dynamic cornering, imperceptible braking intervention on the
inside wheel gives rise to a defined yaw moment around the vertical
axis, resulting in precise cornering by the A 45 AMG and ensuring that
the vehicle remains under control at all times. Curve Dynamic Assist
is adapted according to the selected ESP® mode. In "ESP SPORT
Handling" mode and "ESP OFF" mode it supports the
driver's wish for increased agility and driving dynamics. ESP® Curve
Dynamic Assist is an additional function of the Electronic Stability
Program which noticeably improves not only agility, but also active
driving safety in critical conditions.
AMG sports suspension with independent front and rear axle
Like every AMG high-performance automobile, the new A 45 AMG also
incorporates sophisticated axle technology. For enhanced driving
dynamics, the three-link front suspension is provided with stiffer
steering knuckles and totally new elastokinematics. Newly developed,
more rigid bearings are employed in the lower link plane. These
provide for more agile cornering properties and more precise and
direct feedback from the road surface. The more rigid bearings also
lead to higher camber stiffness, enabling higher cornering speeds. In
developing the complete front axle, great importance has been attached
to attaining the best possible traction in highly dynamic driving.
The four-link rear axle of the A 45 AMG is also a totally new
development. In the course of optimising the elastokinematics, the
strut bearings were duly adapted for maximum driving dynamics and
control. The rear axle carrier is provided with more rigid bearings
for increased driving stability; the subframe is rigidly connected to
the body. The AMG sports suspension with specifically tuned
spring/damper units and larger stabilisers provides for high lateral
acceleration and a reduced rolling tendency in fast double bends. The
A 45 AMG comes as standard with twin-spoke AMG light-alloy wheels,
painted in titanium grey with a high-sheen finish, fitted with 235/40
R 18 tyres.
AMG speed-sensitive sports steering and AMG high-performance braking
system
The electromechanical Dual Pinion AMG speed-sensitive sports steering
with AMG-specific, speed-dependent power assistance and a constant
steering ratio (14.5 : 1) enables high steering precision and agility.
The electric motor is installed in space-saving configuration on the
steering gear. The AMG high-performance braking system with ventilated
and perforated brake discs all round in size 350 x 32 millimetres at
the front and 330 x 22 millimetres at the rear provides for
spontaneous and reliable deceleration.
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.
Dynamic and exclusive interior design and appointments
Inside, too, the new A 45 AMG boasts a heady mix of hallmark
Mercedes-AMG dynamism and exclusivity. The sports seats in ARTICO
man-made leather/DINAMICA microfibre with red contrasting
topstitching, the multifunction steering wheel with shift paddles and
the AMG DRIVE UNIT set new standards in terms of both appearance and
quality. The dashboard trim comes in carbon-fibre look ? a perfect
match for the five air vents in black/red, the red seat belts and the
AMG door sill panels. The AMG instrument cluster presents information
by means of a central colour display with the AMG main menu and the
RACETIMER.
Numerous individualisation options are available for the A 45 AMG

Expressive and exclusive: the A 45 AMG "Edition 1"
The A 45 AMG "Edition 1" stands apart both on a technical
level and in terms of appearance.As is familiar from the CLS 63 AMG
Shooting Brake, the fully appointed "Edition 1" model
variant boasts an expressive composition of exclusive exterior and
interior details. The A 45 AMG "Edition 1" focuses on the
car's affinity to motorsport: the exterior paint finish in cirrus
white corresponds with the AMG sports stripes in matt graphite grey on
the bonnet, roof and sides. The red highlights on the radiator grille,
exterior mirrors and rear aerofoil leave a lasting impression. These
highlights combine to perfection with the red painted brake callipers
and the AMG multispoke light-alloy wheels painted in matt black with
special AMG hub caps in central-locking look. The 8 x 19 light-alloy
wheels are fitted all-round with tyres in size 235/35 R 19. Both the
AMG Night package and the Aerodynamics package feature as standard for
the "Edition 1", providing the perfect finishing touch to
the model's motorsport-inspired character.
Black and red dominate the interior of the A 45 AMG "Edition
1", too.Red contrasting stitching embellishes the AMG Performance
seats in ARTICO man-made leather/DINAMICA microfibre, the top section
of the dashboard in ARTICO man-made leather and the AMG Performance
steering wheel in nappa leather/DINAMICA microfibre. Other visual
highlights are the E-SELECT lever with embossed AMG emblem and the
"Edition 1" badge on the AMG DRIVE UNIT.
The world premiere of the A 45 AMG will take place at the Geneva Motor
Show, whose doors open on 5 March 2013. The sales release date will be
8 April 2013; the market launch in Germany will begin this June.
