(from Audi Press
Release) The Audi TT RS: A Pure Driving Machine
developing 340 bhp
Audi is once again producing a five-cylinder engine – and a very
special one at that. Arriving at dealerships this summer, the TT RS
has a turbocharged 2.5-liter engine with direct gasoline injection;
it produces 250 kW (340 bhp) and 450 Nm (331.90 lb.-ft.) of torque.
The blazing five-cylinder engine enables the TT RS to perform
extraordinary feats. In conjunction with quattro permanent all-wheel
drive and a high-performance chassis, the engine makes the compact
Audi TT RS a top-notch sports car – available as a coupé or
Sporty five-cylinder gasoline engines have a long legacy at Audi.
The most famous is arguably the turbocharged 2.1-liter engine in the
Audi quattro. The first version, which was launched in 1980, offered
an impressive 147 kW (200 bhp). And the Sport quattro from 1984,
directly inspired by motorsport, delivered a whopping 225 kW (306
bhp). For 25 years, turbochargers and quattro have been a dynamic
formula for success.
Audi has resumed using this recipe. Designed from scratch, the
five-cylinder engine combines a turbocharger with FSI direct
gasoline injection to elevate the TT RS to a high-performance sports
car. The TFSI delivers 250 kW (340 bhp) from a displacement of 2,480
cc (151.34 cu in): a specific output of 100.8 kW (137.1 bhp) per
The power-to-weight ratio is also outstanding. In the case of the
Coupé, which weighs in at a mere 1,450 kilograms (3,196.70 pounds),
the power-to-weight ratio is just 4.3 kilograms per bhp.
The TT RS Coupé rockets
from 0 to 100 km/h (0 to 62.14 mph) in 4.6 seconds; the Roadster
needs just a tenth of a second longer. The limited top speed of 250
km/h (155.34 mph) is merely the official figure for both versions;
as an option, Audi can increase it to 280 km/h (173.98 mph).
Almost even more impressive is the aggressive pulling power. The
maximum torque of 450 Nm (331.90 lb.-ft.) is always available
between 1,600 and 5,300 rpm. In addition, the TT RS overtakes
without the slightest effort. Last but not least, its engine makes
passengers’ skin tingle time and again thanks to its speedy and
powerful response, its inspiring free-revving character, and its
unmistakably guttural tailpipes: five-cylinder classical music by
Compact and Lightweight: The
As an uncompromising
sports-car engine, the 2.5-liter TFSI is ultra-compact. Just 49
centimeters (19.29 inches) in length, it is ideally suited for
transverse installation in the TT RS. And its weight of just 183
kilograms (403.45 pounds) also sets a record. The crankcase is made
of vermicular-graphite cast iron. This high-tech material unites the
utmost in strength with low weight; it has otherwise only been used
for the large TDI engines from Audi. Perfectly placed reinforcements
enhance the block’s loadability. The lightweight cylinder head, the
pistons, and the connecting rod are lightweight as well as
The ultra-powerful five-cylinder engine is extremely fuel-efficient,
requiring an average of just 9.2 liters/100 km [25.57 mpg] as
regards the Coupé (Roadster: 9.5 l/100 km [24.76 mpg]). Switchable
flaps in the intake manifold mix the incoming air in a calculated
configuration. Injected at a pressure as high as 120 bar by the
common-rail system, the gasoline swirls intensely in the combustion
chamber – which in turn cools the walls. This subsequently
facilitates a compression ratio of 10.0:1, which is very high for a
turbocharged engine. Both of the adjustable camshafts, controlled
via chains, also enhance charging efficiency with respect to the
The large turbocharger generates up to 1.2 bar of boost pressure.
The intercooler, fed air ideally by the lower segment of the single
frame radiator grille, reduces the temperature of compressed air by
over 80 percent at full load.
When an Audi TT RS driver pushes the standard Sport button on the
center tunnel, a flap installed in the left exhaust tailpipe renders
the exhaust noise even more robust and intense while boosting engine
responsiveness. An optional Sport exhaust system is available with
matt black tailpipe trims and sound flap.
For Purists: The Driveline
The Audi TT RS is the
first classic sports car in the Audi RS family. Like the RS 4 and
the RS 6, the Audi TT RS was developed by quattro GmbH as a pure,
no-holds-barred driving machine. A new six-speed manual transmission
conveys the engine’s tremendous power, and permits easy and precise
operation thanks to a specially designed shift lever boasting
particularly short shift travel. The transmission’s defining
characteristics are a high efficiency ratio and a sportily narrow
spread of the gear ratios.
The Audi TT RS features quattro permanent all-wheel drive as
standard equipment. Its heart lies at the rear axle: an
electronically controlled, hydraulic multi-plate clutch. If a
situation calls for it, the clutch redirects a majority of the
torque input from the front wheels to the rear wheels.
Within milliseconds, a powerful electrical pump in conjunction with
an accumulator presses together the clutch’s plates via hydraulic
pressure. Additions to the quattro powertrain include a constant
velocity joint before the propeller shaft and a compact rear-axle
differential – both are heavy-duty components.
The quattro drivetrain grants the Audi TT RS outstanding traction,
fascinating dynamics, and superb stability. Winding rural routes or
some laps around a racetrack allow the superior handling to shine.
The precise and responsive steering, the instantaneous reactions of
the chassis, the neutrality at the cornering limit, the grip while
exiting a curve, and – time and again – the engine’s thrilling
power: every mile in an Audi TT RS exudes the distilled essence of
High-tech Excellence from Audi:
Chassis and Body
The chassis of the Audi
TT RS builds on the cutting-edge foundation of the base TT design.
The four-link rear suspension, which handles longitudinal and
lateral forces separately, plays a crucial role. The
electromechanical steering is highly efficient and the power
steering adjusts to the vehicle’s speed. With aluminum in the front
and sheet steel in the back, the body’s innovative mixture of
materials results in a well-balanced axle-load distribution,
excellent crash safety, and the outstanding rigidity which lays the
cornerstone for the car’s precise handling.
The standard sports chassis, which lowers the body by 10 millimeters
(0.39 inches), features tightly tuned springs and shock absorbers.
The optional Audi magnetic ride adaptive damping system allows the
driver to select one of two modes for the shock absorbers by simply
pushing the Sport button. Dynamic mode enables the TT RS to hug the
road; Comfort mode provides a pleasantly balanced ride perfect for
The sportiest version in the TT model line boasts 18-inch wheels
fitted with 245/45 tires. They are complemented by mighty ventilated
disc brakes, which measure 370 millimeters (14.57 inches) in
diameter at the front and 310 millimeters (12.20 inches) at the
rear. So that heat dissipates quickly, the front friction rings are
perforated. They, in turn, are connected by hollow pins to the
aluminum brake discs, which are encircled by black four-piston brake
calipers made of aluminum and bearing RS logos.
The Electronic Stabilization Program (ESP) can be switched off
partially or entirely. In Sport mode, the engine does not intervene
to monitor traction and, correspondingly, the brakes engage later
than otherwise. In the second mode, the ESP is fully deactivated.
The Face of Power: The Exterior
At just 4.20 meters
(13.78 feet) in length, the vigorously compact Audi TT RS hints at
its explosive potential from the very first glimpse. The front
spoiler tapers downward into a splitter, reminiscent of a racing
car. The large and squared air inlets have diamond-shaped inserts.
And the high-gloss black single frame grille with a frame in matt
aluminum look and the TT RS badge bear the same styling. The xenon
plus headlights with LED daytime running lights notify faraway
drivers that an Audi TT RS is approaching.
The sides of the vehicle are accentuated by large wheels in 5
twin-spoke design, vigorous side sills, and exterior-mirror casings
in matt aluminum look. At the tail end, the two large oval exhaust
tailpipes – spaced apart – are encircled by a diffuser insert. Here,
too, is a TT RS badge. A stationary rear spoiler is standard, though
customers can opt for one which automatically extends and retracts.
Thanks to a drag coefficient of just 0.3, the 2+2-seat coupé and the
two-seat roadster glide effortlessly through the wind. Audi offers
the TT RS in eight colors. Among them are four exclusive options:
Daytona Gray, pearl effect; Mugello Blue, pearl effect; Sepang Blue,
pearl effect; and Suzuka Gray, metallic. The Roadster’s soft top
comes in black or dark gray.
Exclusive Character: Interior and
The dynamic exterior of
the Audi TT RS is matched by the interior. The leather multifunction
sports steering wheel has an especially thick rim, is flat-bottomed,
and is covered with perforated leather. Integrated in the instrument
panel, the driver information system can display boost pressure and
oil temperature as well as a lap timer for chronicling feats at the
racetrack. The door handles consist of two slim strips – typical of
Audi RS models. An automatic climate-control system and the concert
sound system are standard, as are an electrohydraulic soft top and
an electric wind deflector for the Roadster.
The entire interior is black. The heated sports seats feature an
Alcantara/leather combination with silver contrasting stitching and
embossed TT RS logos in the front backrests. Additional badges and
logos appear on the steering wheel, in the rev counter, and on the
door sill trims. The inlays are made from brushed aluminum. Floor
mats feature silver piping trim; footrests and pedals are in
Audi offers TT RS customers a diverse range of optional equipment:
variably styled wheels measuring 18, 19 or 20 inches in diameter;
bucket seats with folding backrests; seat upholstery in Silk Nappa
leather with perforations or Fine Nappa leather with special TT
perforations; inlays with Ibis White or Phantom Black paint finish
as well as matt aluminum-look inlays for the exterior. In addition,
there are high-tech navigation and multimedia systems available.
Sales of the Audi TT RS begin in March; deliveries are scheduled to
begin this summer.
