The automaker from Ingolstadt has just released photos and details with the facelift versions 2011 Audi TT Coupe and Roadster.
Starting to the exterior the 2011 Audi TT Coupe and Roadster received a new front bumper with larger air intakes, a revamped front grille, slightly redesigned front lights with 12 LEDs, larger exhaust pipes and a discrete new diffuser.  
Inside the 2011 Audi TT Coupe and Roadster occupants will feel an increase in the level of comfort while under the bonnet the company added the new fuel efficient 2.0-litre TFSI engine that produces 211 HP (155 kW) and 258 lb-ft of torque.
With this new powering unit the 2011 Audi TT Coupe and Roadster are able to hit 100 Km/h (62 mph) from a stand still in 6.1 seconds, and reach a top speed of 245 Km/h (152 mph). The 2011 TT 2.0 TFSI needs 6.6 liters
of fuel per 100 km
(35.6 mpg) while CO2
emissions are of 154 g/km.

As for the 2011 Audi TTS and TT RS power will get extracted from the same 272 HP and 340 HP engines with a new S tronic dual clutch transmissionto be fitted on the TT RS variant later this year.
The 2011 Audi TTS goes on sale in Fall 2010, while the
TT 2.0 TFSI quattro goes on sale at the beginning of 2011.
On their home market the 2011 Audi TT Coupe and Roadster will become available this summer and the automaker has already announced the 2011 Audi TT 1.8 TFSI price which will start from 30,200 Euro.
Audi press release :
Dynamic design, enthralling performance and exemplary efficiency – the
Audi TT Coupe and the TT Roadster are now more attractive than ever.
The design of the lightweight bodies made primarily of aluminum and the
interior have been revised with great attention to detail, while new
technologies lower the fuel consumption of the compact sports car. New
to the lineup is a powerful and highly efficient four cylinder: The 2.0
TFSI develops 155 kW (211 hp), but is content with an average fuel
consumption of just 6.6 liters per 100 kilometers (35.64 US mpg). 
Exterior design
The second generation TT Coupe and the TT Roadster have made a name for
themselves as design icons, similar to their predecessors. Awards such
as the 2007 “World Car Design of the Year” document this status. A
brawny, broad foundation, powerful shoulders and a flat roofline – the
two compact sports cars have fascinatingly masculine lines. Their
dynamic appearance is now even more expressive than ever.
The most obvious feature at the front of the car is the powerful
bumper, which frames the larger air inlets with three-dimensional,
sharply drawn out edges. The fog lights are set in chrome rings. Also
sporting a new look are the lattice of the single-frame grille in
high-gloss black and the optional xenon plus headlights. Twelve white
LEDs arranged in a straight line at the lower edge of the headlights
serve as the daytime running lights. These together with the wings in
the headlight body are classic Audi design features.
The tubular, apparently floating reflectors of the tail lights add
visual depth to the rear end of the car. The large tailpipes of the
exhaust system – the 2.0 TFSI features a dual exhaust – and the larger,
flat black diffuser set additional accents. A spoiler that extends at
120 km/h (74.56 mph) improves downforce.
The upgrades to the TT Coupe and the TT Roadster have added two
centimeters (0.79 in) to both cars, which now measure 4,187 millimeters
(13.74 ft) in length. The width of 1,842 millimeters (6.04 ft) and the
height of 1,352 millimeters (4.44 ft) and 1,357 millimeters (4.45 ft)
for the Coupe and Roadster, respectively, remain unchanged. The
wheelbase measures 2,468 millimeters (8.10 ft). Four new metallic
colors have been added to the TT color range: Scuba Blue, Oolong Gray,
Volcano Red and Dakota Gray. Daytona Gray, pearl effect is also
available with the S line package.
Body
A key factor for the groundbreaking efficiency and excellent driving
dynamics of the TT is the body, which features hybrid Audi Space Frame
technology (ASF). Lightweight aluminum is used at the front of the car
back to the B-pillar, with steel panels used at the rear. This mix
enabled the development engineers to balance the axial loads perfectly
and keep the total weight extremely low – prime parameters for dynamic
performance.
The TT 1.8 TFSI weighs a mere 1,240 kg (2,733.73 lb), a good 100
kilograms (220.46 lbs) less than its closest competitor. The body of
the Coupés weighs only 206 kilograms (454.15 lb), which breaks down to
140 kilograms (308.65 lb) of aluminum (68 percent) and 66 kilograms
(145.51 lb) of steel (32 percent). The specific reinforcements in the
TT Roadster – steel bulkhead, strongly ribbed sills, A-pillar and
windshield frame – result in a 58 to 42 percent split of the two
materials.
The ASF bodies of the TT are not only extremely lightweight, they are
also very strong and low-vibration, providing the foundation for sporty
and precise handling, the quiet ride and the high passive safety. A
package of finely tuned retention systems protects the passengers in
the event of a crash. The classic cloth top of the TT Roadster is a
perfect complement to Audi’s lightweight construction principle. It
contributes to a low center of gravity, fits ideally into the design
line and takes up little space when folded.
Audi offers the soft top in two variants. The manual version features a
central latch for opening and closing the top. An electrohydraulic
drive opens the optional fully-automatic top in just 12 seconds, even
while driving at speeds up to 50 km/h (31.07 mph). An additional
acoustic mat further improves the already excellent acoustics and
thermal insulation.
Interior
The interior of the TT features a sporty design, dynamic elegance and
generous amounts of space. The standard sport seats are mounted low and
offer a high level of lateral support. The steering wheel is flattened
at the bottom. The five round air vents and the arched cowl over the
round-dial instruments exude the spirit characteristic of the TT. The
ergonomics are logical and the fit and finish is uncompromisingly
precise – just like always with Audi. When the ignition is turned, the
dials of the speedometer and tachometer briefly run up to the limit
before returning to zero.
The designers have added additional gloss to the fine interior. New
aluminum-look applications shine on the steering wheel, the center
console and in the door liner. Elegant accents are provided by rings,
frames and strips in high-gloss black. The aluminum strip above the
glove box door is now brushed gray. There are three new interior colors
from which to choose – nougat brown, titanium gray and garnet red. The
leather seat covers are specially treated to reduce thermal heating by
as much as 20 degrees Celsius (68° F) when the TT is parked in the sun.
The TT Coupe and the TT Roadster are sports cars with a high degree of
everyday utility. The backs of both rear seats fold down in the
2+2-seater Coupé, expanding the trunk space beneath the long lid from
292 to 700 liters (10.31 – 24.72 cubic ft). The Roadster, which offers
250 liters (8.83 cubic ft) of storage space whether the top is up or
down, can also be supplied with the option of a load-through facility.
Drivetrain
Three four-cylinder engines with turbocharging and direct fuel
injection are available for both the TT Coupe and the TT Roadster. The
two TFSI gasoline engines and the TDI combine sporty performance with
groundbreaking efficiency – their fuel consumption figures have been
reduced by up to 14 percent. All three engines are coupled with a
recuperation system that recovers energy during braking and coasting
phases.
New to the lineup is the 2.0 TFSI with 155 kW (211 hp), which replaces
the 2.0 TFSI with 147 kW (200 hp) and the 3.2 FSI. With a manual
transmission, the two-liter engine accelerates the Coupe from zero to
100 km/h (62.14 mph) in 6.1 seconds on its way to a top speed of 245
km/h (152.24 mph). Audi also offers the 2.0 TFSI with an optional
drivetrain featuring the six-speed S tronic and quattro permanent
all-wheel drive. The spring from zero to 100 km/h (62.14 mph) takes
only 5.6 s in this configuration.
The Audi valvelift system AVS in the new 2.0 TFSI increases power,
torque and efficiency. Equipped with a manual transmission, the TT 2.0
TFSI consumes only 6.6 liters of fuel per 100 km (35.64 US mpg) in the
European test cycle. CO2 emissions are an exemplary 154 grams/km
(247.84 g/mile). The best value posted by a competitor is 199 g/km
(320.26 g/mile). Fuel consumption has improved by 1.1 liters/100 km
over the previous model.
The 2.0 TFSI is a winner par excellence, having been named “Engine of
the Year” five years in a row by an international jury. Its technology
package combines high output with impressive pulling power. A constant
350 Nm (258.15 lb-ft) of torque are available between 1,600 and 4,200
rpm. The long-stroke engine, which is extremely cultivated thanks to
two balance shafts, has been painstakingly optimized for minimal
friction.
The Audi valvelift system adjusts the lift of the exhaust valves in two
stages depending on need. This reduces flushing losses in the
combustion chamber and also ensures that the optimal flow of the
exhaust gas is directed to the turbocharger, which in turn ensures that
torque is developed quickly.
The combination of turbocharging and direct fuel injection also reduces
the combustion chamber temperatures and the resulting tendency to
knock. This allows a high compression ratio of 9.6:1, which improves
efficiency.
The TT engine lineup includes two other four-cylinder engines besides
the new 2.0 TFSI. The 1.8 TFSI, available with a six-speed manual
transmission and front-wheel drive, delivers 118 kW (160 hp) and 250 Nm
of torque (184.39 lb-ft), the latter between 1,500 and 4,500 rpm. It
launches the Coupe from a standing start to 100 km/h in 7.2 seconds,
with a top speed of 226 km/h (140.43 mph). It consumes just 6.4 liters
of fuel per 100 km (36.75 US mpg) on average, which corresponds to only
149 grams of CO2/km (239.79 g/mile). The TT 2.0 TDI remains the only
sports car with a diesel engine in its segment, and its efficiency
clearly sets the standard. The TT Coupe consumes just 5.3 liters of
fuel per 100 km (44.38 US mpg), which corresponds to only 139 grams of
CO2/km (223.70 g/mile). With 125 kW (170 hp) and 350 Nm (258.15 lb-ft)
of torque – the latter available between 1,750 and 2,500 rpm – the
standard sprint takes 7.5 seconds and acceleration continues until a
top speed of 226 km/h (140.43 mph) is reached. The two-liter TDI is
mated to a manual transmission and quattro all-wheel drive.
A precisely shifting six-speed manual transmission transfers power to
the wheels regardless of the engine. Audi also offers the S tronic dual
clutch transmission as an option for the new 2.0 TFSI. This
transmission switches between its six gears with virtually no
interruption to the supply of power. The high-tech gearbox shifts
extremely quickly and comfortably, either fully automatically or
manually as the driver desires. Manual shifts can be made using the
optional paddles on the steering wheel.
The quattro permanent all-wheel drive system is available as an option
for the 2.0 TFSI with the S tronic; it comes standard with the 2.0 TDI.
The hydraulic multi-plate clutch, which is mounted on the rear axle in
the interest of weight distribution, is electronically controlled.
During normal driving, it sends most of the engine’s power to the front
wheels, but can quickly transfer up to 100 percent to the rear wheels,
if necessary.
The quattro drive provides substantially greater stability, traction
and driving enjoyment, and is another unique selling point of the Audi
TT in its class.
Chassis
The front suspension features McPherson struts, with aluminum
components used to keep the weight of the unsprung masses low. The
power steering is direct, sensitive and thanks to its electromechanical
drive, highly efficient. The trailing arms of the four-link rear
suspension are relatively soft in the interest of comfort. The
connections to the three transverse links per wheel, on the other hand,
are rigid in order to direct lateral forces into the body with
precision.
Available as an option with all variants of the TT is the
electronically controlled Audi magnetic ride shock absorber system,
another high-tech feature that underscores the unique character of the
compact sports car. A fluid containing tiny magnetic particles
circulates through the dampers. When a voltage is applied to the
magnetic field, the behavior of the particles changes and thus the
damping behavior of the fluid changes. A computer fed with input from a
bundle of sensors controls the adaptive damping.
The driver can choose between two base characteristics, which are now
even more clearly differentiated. In “Normal” mode, the movements of
the TT Coupe and the TT Roadster are balanced – equally agile and
comfortable. In “Sport” mode, high damping forces largely suppress body
roll. The TT is tautly connected to the road, and its setup is highly
dynamic.
Another option is available in addition to Audi magnetic ride – the
Sport button. The driver can use it to adjust the characteristic of the
gas pedal (with manual transmissions), the amount of servo boost for
the steering and the engine sound in two stages.
The range of wheels has also been reworked, and now features 14
variants. The TT 1.8 TFSI, the 2.0 TDI and the 2.0 TFSI roll off the
assembly line on 17-inch aluminum wheels with size 245/55 tires.
Winter wheels are available in three sizes; the range of summer wheels
extends all the way up to 9 J x 19 with size 255/35 tires. Mounted
behind the large wheels are powerful brakes with large-diameter discs.
The front discs are internally ventilated.
Equipment and trim
All versions of the TT Coupe and TT Roadster come with a rich array of
standard equipment. Among the highlights are the “chorus” audio system,
a driver information system and – in the TT Coupe– an automatic climate
control system. Two navigation systems, a universal cellular phone
preparation and the sonorous Bose Surround Sound system are available
as options. The optional xenon plus headlights can be combined with a
cornering light function.
The onboard computer with efficiency program comes standard in the TT.
It displays all of the consumption-relevant data on the central
display, and gives the driver tips for efficient driving. The
gear-change indicator indicates the proper gear. Another function
provides information on which vehicle systems, such as the climate
control system, are consuming energy and how that effects fuel
consumption.
Customizing fans will find a rich selection available in Color &
Trim. It begins with the optional leather upholstery and includes four
leather packages, an application package and two S line packages. The S
line exterior package focuses on design modifications in the area of
the bumpers, the air inlets and the diffuser. The S line sport package
features a black interior with many fine details in such places as the
steering wheel, the seat covers and the applications. 18-inch wheels
and body lowered by 10 millimeters (0.39 in) make the handling even
more dynamic.
The updated TT Coupe and the TT Roadster will debut on the German
market this summer with only minimal changes in price. The 1.8 TFSI
will be available from €30,200.
The Audi TTS and the Audi TT RS
The Audi TTS, both in Coupe and Roadster body styles, combine
enthralling sportiness with cultivated comfort. Its two-liter TFSI with
the large turbocharger and many additional modifications pumps out 200
kW (272 hp) and 350 Nm (258.15 lb-ft) of torque, the latter from 2,500
to 5,000 rpm. It accelerates the TTS Coupe with the optional S tronic
from zero to 100 km/h (62.14 mph) in 5.2 seconds, up to a governed top
speed of 250 km/h (155.34 mph). With the S tronic, the Coupé consumes
an average of only 7.7 liters of fuel per 100 km (30.55 US mpg).
The TTS comes standard with the Audi magnetic ride adaptive shock
absorber technology, the Sport button and a high-performance brake
system. Visual cues to its identity are provided by the 18-inch wheels
with size 245/40 tires and a new grille combined with chrome air
inlets. A new color combination – spectral silver/black – is available
for the interior.
The dynamic spearhead of the TT model series is the TT RS, which is
likewise available as a Coupe or a Roadster. Its turbocharged, inline
5-cylinder engine draws 250 kW (340 hp) of power from 2.5 liters of
displacement. 450 Nm (331.90 lb-ft) of torque are available between
1,600 and 5,300 rpm. It nevertheless averages just 9.2 liters of fuel
per 100 km (25.57 US mpg).
The TT RS Coupe rockets from 0 to 100 km/h (0 to 62.14 mph) in 4.6
seconds; quattro GmbH will raise the top speed from 250 to 280 km/h
(155.34 to 173.98 mph) upon request. A sound flap in the exhaust system
further intensifies the distinctive five-cylinder sound. A manual
six-speed transmission with a sportily narrow gearing currently
delivers the power to the quattro permanent all-wheel drive. Starting
this fall, Audi will also offer the option of the TT RS with a newly
developed version of the S tronic that can handle the tremendous torque
of the powerful five-cylinder engine. The compact layout of the
seven-speed, dual-clutch transmission makes it suitable for transverse
mounting in combination with the quattro all-wheel drive system.
The TT RS Coupe with the S tronic launches itself from zero to 100 km/h
(62.14 mph) in 4.4 seconds. The TT RS Roadster requires 0.1 seconds
more for this discipline – a bat of an eye less than with the manual
transmission. Distinctive design details, 18-inch wheels and an
extremely powerful brake system are standard with the TT RS.
