221 kW (300 hp) of power
and 380 Nm (280.27 lb-ft) of torque – the third-generation Audi S3
raises the bar once again. Scheduled to launch in early 2013, the
lightweight premium compact model combines its dynamic performance
with groundbreaking efficiency and comes packed with all the
high-tech Audi has to offer in every field of technology.
The long-stroke 2.0 TFSI
in the Audi S3 has been developed from scratch. The only thing it
has in common with its predecessor, which was named Engine of the
Year five times in a row between 2005 and 2009, is its displacement
of 1,984 cc (bore x stroke 82.5 x 92.8 millimeters [3.25 x 3.65
in]). The four-cylinder unit delivers a constant 380 Nm (280.27
lb-ft) of torque to the crankshaft between 1,800 and 5,500 rpm.
Rated power at 5,500 rpm is 221 kW (300 hp), and the engine redlines
at 6,800 rpm.
The S3 delivers impressive performance. The sprint from zero to 100
km/h (62.14 mph) is completed in 5.1 seconds when equipped with the
S tronic (5.4 seconds with the manual transmission). The
electronically governed top speed of 250 km/h (155.34 mph) is just a
formality. The S3 with S tronic consumes on average just 6.9 liters
of fuel per 100 km (manual: 7.0 liters) [34.09 and 33.60 US mpg].
This corresponds to CO2 emissions 159 (162) grams per kilometer
(255.89 and 260.17 g/mile) and for models equipped with the manual
transmission, an improvement of 1.5 liters compared with the
The powerful four-cylinder engine features two balance shafts
rotating at twice the speed of the crankshaft for tremendous
smoothness. The sound is emotion-inspiring and sporty. An
electromechanical sound actuator at the bulkhead brings the engine
sound to life in the cabin. The exhaust system also includes a sound
flap that opens at certain engine speed ranges to give the S3 a
sportily sonorous sound.
The 2.0 TFSI boasts groundbreaking solutions in many fields of
technology. One of these is the additional use of indirect
injection. It supplements the FSI gasoline direct injection at part
load to reduce consumption and particulate emissions. FSI injection,
which works at pressures up to 200 bar, is used when starting and at
The developers achieved new degrees of freedom when it comes to
filling the combustion chambers. On the exhaust side, the Audi
valvelift system varies the stroke of the valves in two stages; the
camshaft on the intake side can be adjusted steplessly through 30
degrees of crankshaft angle while 60 degrees of adjustment is
available on the exhaust side. The compression ratio of 9.3:1 is
unusually high for a turbocharged engine.
The exhaust manifold is integrated into the cylinder head, where it
is bathed in coolant. This solution lowers the temperature of the
exhaust and accelerates warmup following a cold start, which lowers
consumption during the cold-start phase. This concept also has a
positive effect on fuel consumption during sporty driving because
full-load enrichment is no longer necessary. The large turbocharger
is also a new development. It achieves a maximum boost pressure of
up to 1.2 bar for even more spontaneous engine response. A
high-performance intercooler integrated into the water circuit
greatly reduces the temperature of the compressed air and thus
increases the amount of air required for combustion.
With the 2.0 TFSI’s innovative thermal management system, two rotary
slide valves consolidated in a single module regulate the flow of
coolant. These valves ensure that the engine oil heats up to its
operating temperature soon after the vehicle is started; they also
maintain the coolant temperature, as per a given driving situation,
between 85 and 107 degrees Celsius (185.0° F and 224.6° F). As a
result – regardless of load or engine speed – the valves always
strike the perfect balance between minimal friction and high
The 2.0 TFSI has been designed specifically for use in the new Audi
S3. Pistons with stronger bolts and new rings plus reinforced
connecting rods with new mounts transfer the power to the
crankshaft. The gray cast iron crankcase has been reinforced at the
main bearing seats and the main bearing cover.
The cylinder head is made of a new, particularly lightweight
aluminum-silicon alloy characterized by high strength and
An innovative coating on the piston skirts and mounting the balance
shafts in roller bearings keep internal friction low. The regulated
oil pump only consumes as much energy as is necessary for the
current driving situation.
Despite its complexity and the high performance, the new 2.0 TFSI
weighs just 148 kilograms (326.28 lb) – more than five kilograms
(11.02 lb) less than the previous engine. The dimensions are
compact: 603 millimeters (23.74 in) long, 678 millimeters (26.29 in)
wide and 664 millimeters (26.14 in) high.
The new Audi S3 comes
standard with a manual six-speed transmission with a lightweight
magnesium case. The optional S tronic boasts high efficiency and a
tall sixth gear. The lower gears are short in the interest of
dynamics, as is also the case with the manual transmission.
The S tronic comprises two subunits, with two multi-plate clutches
controlling the gears. The large K1 clutch located on the outside
directs the torque via a solid shaft to the gear wheels for gears 1,
3 and 5. A hollow shaft rotates around the solid shaft. It is
connected to the smaller K2 clutch, which is integrated inside its
larger sibling, and which acts on the gear wheels for gears 2, 4 and
6, as well as reverse.
Both transmission structures are continuously active, but only one
of them is connected to the engine at any one time. For example,
when the driver accelerates in third gear, the fourth gear is
already engaged in the second transmission section. Shifts are
performed by switching the clutches. This takes just a few
hundredths of a second and happens so quickly and smoothly that it
is barely perceptible.
S tronic can be operated using the short selector lever or with the
optional paddles on the steering wheel. It includes the modes D and
S in addition to manual mode. The driver can activate launch control
at the push of a button. This manages starts with controlled tire
slip to deliver maximum engine power to the road.
quattro permanent all-wheel drive is an integral component of the
powertrain. It gives the new top model in the A3 series a decisive
edge over its two-wheel-drive competition. The Audi S3 can
accelerate earlier and more safely when exiting a corner. It remains
dynamic and stable under all conditions, particularly in the rain
The heart of the quattro drive system is an electronically
controlled and hydraulically actuated multi-plate clutch. In the
interest of balance axle load distribution, it is located at the end
of the prop shaft, in front of the rear axle differential.
Inside is a package of plates that rotate in an oil bath. The metal
friction rings are arranged behind one another in pairs – one ring
of each pair is rigidly meshed with the housing, which rotates with
the prop shaft; the other ring is meshed with the output shaft to
the rear axle differential.
During normal driving, the clutch sends most of the engine’s power
to the front wheels. If traction decreases there, the clutch can
transfer torque steplessly to the rear axle in just a few
milliseconds by forcing the packages of plates together via
controlled action. An axial piston pump generates the necessary
pressure almost instantaneously.
The new Audi S3 offers
the dynamic driving characteristics of a sports car. It responds to
steering input precisely and spontaneously, and takes all types of
corners at high speed and with little body movement. Its handling is
precise, safe and virtually neutral.
One reason for this performance is the finely balanced distribution
of the axle loads. The front axle has been shifted forward 52
millimeters (2.05 in) compared with the previous model. The new 2.0
TFSI is 5 kilograms (11.02 lb) lighter than the previous engine and
is installed tilted backward by 12 degrees. This layout is a result
of the Group’s modular transverse platform, on which the new Audi S3
The subframe, the pivot bearings in the McPherson front axle, the
crash management system, the front fenders and the engine hood are
made of aluminum. All together they save 17 kilograms (37.48 lb) of
weight. The front wheel suspension has a track width of 1,535
millimeters (60.43 in). A stabilizer bar is used front and rear.
Another innovation in the Audi S3 is progressive steering. The
steering rack is geared in such a way that the ratio varies. It is
somewhat more indirect around the center and very direct when
steered sharply. For the driver, this technology combines a
pleasantly smooth character when driving straight ahead with highly
spontaneous response in tight corners.
The powerful electric motor providing the servo boost harmonizes
perfectly with the character of the steering system, decreasing its
output as speed increases. It consumes no energy when driving
straight ahead and thus reduces fuel consumption by as much as 0.3
liters per 100 kilometers. The progressive steering works closely
together with various systems on board the new S3, such as the
standard rest recommendation and the optional Audi active lane
assist and park assist systems.
The four-link rear suspension has a track width of 1,511 millimeters
(59.49 in). Its sword-shaped trailing links absorb the propulsion
and braking forces. Their bearings are large and relatively elastic
in the interest of a more comfortable ride. On the other hand, the
three wishbones per wheel for absorbing lateral forces are attached
very rigidly to the steel subframe for improved handling. All of the
bearings are sportily taut compared with the A3.
The links of the rear axle are made of high-strength steels; the
wheel carriers are aluminum. The shock absorbers and the compact
coil springs are separate from one another, resulting in sensitive
response and a high luggage capacity. The sport suspension lowers
the body by 25 millimeters (0.98 in) compared with the A3.
The new Audi S3 rolls on 7.5 J x 18 alloy wheels with 225/40-series
tires. The wheels sport an S-specific design with five parallel
spokes. They are produced using sophisticated flow forming
technology, in which the outer rim is rolled out over a cylinder at
high pressure and high temperature. While the system is shaping the
wheel blank it is also strengthening the material, which allows for
thinner wall thicknesses – the wheel is lighter, yet stronger.
Despite their dynamic performance, the tires also feature low
rolling resistance and thus contribute to the efficiency of the Audi
The brakes of the new S3 can be very precisely metered. The pedal
feel is spontaneous and firm. The front discs are internally vented
and measure 340 millimeters (13.39 in) in diameter. The black brake
calipers are emblazoned with S3 logos. The new electromechanical
parking brake, which the driver operates via a button, is integrated
into the rear axle brake system. The latest evolution of the ESC
electronic stabilization control intercedes very precisely.
Audi drive select comes standard in the new Audi S3. It incorporates
the characteristics of the electronic accelerator, the boost of the
progressive steering and the shift points of the optional S tronic.
The driver determines with the push of a button whether these
systems operate in comfort, auto, dynamic, efficiency or individual
mode. In individual mode (available with the MMI radio or above),
drivers can compose their own preferred profile within certain
In efficiency mode, the function of the standard deluxe automatic
air conditioning, the cruise control or adaptive cruise control and
the adaptive light is modified for optimal fuel consumption. In this
case, the S tronic switches to coasting mode when the driver takes
his or her foot off the gas pedal.
Another optional module integrated into Audi drive select is the
electromagnetic damper control system Audi magnetic ride. A
synthetic hydrocarbon oil containing microscopically small magnetic
particles circulates within the damper pistons. When a coil applies
a voltage, the particles align perpendicular to the direction of
flow of the oil, impeding its flow through the channels in the
The control unit constantly analyzes the condition of the road and
the driver’s style, repeatedly adapting the damper forces within
milliseconds. The driver can choose between three modes. The new S3
is balanced in normal mode and tightly connected to the road in
sport mode. Steering response becomes even more spontaneous, and yaw
movements are largely suppressed.
construction is an Audi core competence. The new S3 weighs no more
than 1,395 kilograms (3,075.45 lb), a value that is easily the best
in its competitive environment. Compared with the previous model,
curb weight has been reduced by 60 kilograms (132.28 lb). Thanks to
hot-shaped, high-tech steels, the body-in-white alone represents a
weight saving of 28 kilograms (61.73 lb) over the previous model.
The large aluminum parts in the front section of the car round out
the lightweight construction concept.
The three-door body of the S3 is also very stiff, crash-safe and
quiet. A noise-insulating windshield is standard. The coefficient of
drag is just 0.33. The new Audi S3 is 4,254 millimeters (13.96 ft)
long, 1,777 millimeters (5.83 ft) wide and 1,435 millimeters (4.71
ft) tall. Its wheelbase measures 2,595 millimeters (8.51 ft), 17
millimeters (0.67 in) more than its predecessor.
The new Audi S3 has a
firm and sporty road stance. Each element of the design is precise
and distinctive. The athletic sculpture with the low engine hood,
the characteristic tornado line below the windows and the sharply
sloped C-pillars stretch the body visually. Audi supplies xenon plus
headlights with LED daytime running lights as standard. The flat
rear lights, into which the adaptive brake light is integrated, are
also fitted with light-emitting diodes.
The xenon-based Audi adaptive light swivels into curves. It is also
linked to the navigation system and can be upgraded with special
lighting functions of urban, interurban and highway driving, as well
as for intersections and tourist attractions. When combined with the
front-facing camera, the light-dark boundary of the headlights is
automatically and steplessly adjusted for substantially improved
visibility and safety.
A true first in the premium compact class are the optional LED
headlights, which previously have only been available in full-size
models. The low beams are generated in two free-form reflectors with
a total of nine high-performance LED chips. Ten high-performance
LEDs in the matt aluminum trim provide the high beams. Depending on
the features chosen, the high beams are switched on automatically
and LED cornering lights illuminate tight corners. Interurban,
highway and tourist attraction lighting round out the lighting
convenience functions. The all-weather lights enhance safety in fog
The Audi S3 sports the S-specific single-frame grille as a symbol of
uncompromised sportiness. The frame has an aluminum-look finish, and
the insert is matt platinum gray. The horizontal double bars also
shine in an aluminum-look finish. The newly designed bumper features
aluminum-look double ribs integrated into the lateral air inlets.
Pronounced edges frame the large air inlets with the high-gloss
black honeycomb inserts. Additional implied air openings are found
toward the wheels.
When viewed from the side, the aluminum-look exterior mirrors and
the pronounced side sills catch the eye. The rear bumper has also
been redesigned. The platinum gray diffuser houses the exhaust
system’s four oval tailpipes, which sport chrome tips. A large roof
spoiler generates downforce on the rear axle.
S badges adorn the rear and the single-frame grille. Highlights
among the 14 colors available for the Audi S3 are the exclusive
crystal-effect finishes Panther Black and Estoril Blue.
The athletic design of
the exterior carries over into the interior. A distinct arch
encircles the instrument panel; slim and low, the instrument panel
appears to float on the center console. Large, round air vents, the
elegant control panel for the air conditioning and the decorative
inlays in matt brushed aluminum or a black 3D look provide exquisite
accents. The controls are clear and intuitive, as in every Audi. The
quality is unsurpassed and there is a generous amount of room.
Luggage capacity is 365 liters (12.89 cu ft), which can be increased
to 1,100 liters (38.85 cu ft) by folding down the rear seats.
The instrument dials are gray, the needles white. Another S-specific
feature can be found on the tachometer, which now includes a boost
pressure indicator. The driver information system with rest
recommendation is standard; the power-retractable on-board monitor
(standard with the MMI radio and above) powers up to display a
special S3 screen when the ignition is turned. The optional leather
multifunction sport steering wheel has been redesigned with the
flat-bottomed rim. In models equipped with S tronic, it also has
aluminum-look shift paddles. The pedals and footrest are made of
The sport seats with the pull-out seat cushions are also a new
development. The seat coverings are one of three variants: In the
first, the large side bolsters are covered in Pearl Nappa leather
while the seat center sections are covered in cloth. The second is a
combination of perforated Alcantara and Pearl Nappa leather. The
third variant is a mix of Velvet leather with Fine Nappa leather.
Audi also offers optional S sport seats with integrated head
restraints and diamond quilting.
The interior of the S3, including the headlining, is in black with
contrasting stitching. The two-color Audi design selection in
black/parade red is available as an option.
S logos adorn the door sill strips, the steering wheel, the
gear/selector lever knob and the instruments. The two-zone deluxe
automatic air conditioning and the storage package are standard in
the Audi S3.
If desired, Audi equips
the new S3 with all of the groundbreaking mobile infotainment and
driver assistance solutions available for the model series. Audi
connect is the name for a broad range of tailored online services
that network drivers with their surroundings and rapidly supply them
with key information in an easy-to-comprehend format.
Audi has designed a variety of infotainment elements for using the
new services, topped by MMI navigation plus with MMI touch. The
high-end system boasts a super-flat, power-retractable, seven-inch
monitor and a new operating concept in which MMI touch is integrated
into the rotary pushbutton. The Audi Phone Box connects cell phones
to the vehicle in a convenient way, and the sound system from Bang &
Olufsen offers pure hi-fi enjoyment, with LED light guides
accentuating the woofers in the doors.
The assistance systems in the S3 come directly from the full-size
class. The range begins with adaptive cruise control, which when
combined with the safety system Audi pre sense front brings the car
to a stop autonomously from speeds below 30 km/h (18.64 mph), and
continues through Audi side assist, Audi active lane assist and
camera-based traffic sign recognition to the park assist system.
There are also a number of sporty and convenient options, including
adaptive light (also with variable headlight range control), the
convenience key and the panoramic glass roof.
The Audi S3 will arrive at dealerships in early 2013. The base price
in Germany is €38,900.
