(from Audi Press
Release) Sheer sportiness, a genuine driving experience
plus high power reserves – cue the new TT Roadster from Audi. The
open-top sports car retains the distinctive lines of its
tremendously successful predecessor, but instils them with even
greater emotion, performance and dynamism.
Note: Specifications listed are for European market. U.S. vehicles
may have different specifications.
Audi offers a choice of two engines for its new TT Roadster. The
3.2-liter V6 power unit generates 250 hp and is coupled to the
quattro drive system as standard. The 2.0 TFSI engine, which blends
turbocharging with gasoline direct injection technology, delivers
200 hp to the front wheels. Both model variants can be ordered with
the innovative S tronic dual-clutch gearbox as an alternative to the
standard six-speed manual shift.
The chassis of the new Roadster is also built for impressive sporty
performance. Its highlight is Audi magnetic ride, the optional
suspension damping technology that allows drivers to choose between
an uncompromisingly dynamic ride or more comfort-orientated
To mirror the puristic character of open-top motoring, the boldly
styled body is crowned by a lightweight cloth hood. The TT Roadster
3.2 quattro comes as standard with a quick-action, fully automatic
softtop which is available as an option for the 2.0 TFSI.
The exterior design
With its rigorous
geometry and clarity, the design of the first TT Roadster elevated
it to the status of a cult classic. Audi has preserved the
charismatic design idiom and carefully honed it for the new model.
Whereas the tail end and the roof section seem to flow into one
another at the rear of the TT Coupé, the soft top of the TT Roadster
forms a clear contrast that gives the overall design a more
geometric look. The body's lines brim with power and forward thrust.
This impression is underscored by the athletic curves of the
vehicle's flanks just as much as by the rising dynamic line above
the sill area and the taut, muscular shoulder line. The eye-catching
fuel filler cap positioned above the rear right wheel sports a
classic aluminum design.
The face of the new Audi TT Roadster has an expressive feel.
Wing-shaped plastic elements are embedded into the slanted, sharply
tapered headlights to emphasize the three-dimensional depth of the
lamp units. At the rear of the car, it is the large tailpipes and
the wide diffuser which stand out. The tube-shaped reflectors seem
to hover inside the tail light units. As on the Coupé, an
electrically powered spoiler rises up out of the boot lid when the
speed reaches 75 mph.
Compared to the model it replaces the new TT Roadster has undergone
a growth spurt, with the new proportions accentuating its sporty
nature. Length is now 164.5 inches (+ 5.4 in), width 72.5 in. (+
3.1) and height 53.5 in. (+ 0.3 in), while the wheelbase has been
extended by 1.8 to 97.1 in. Despite the extra size, however, the
drag coefficient of the 2.0 TFSI is just 0.32 with the soft top up.
The soft top
Audi made a conscious
decision to keep the cloth hood for the new TT Roadster. The soft
top concept fits in perfectly with the philosophy of puristic
open-top motoring and also offers a number of benefits over a
folding steel hard top.
The cloth hood, incorporating reinforcements made from steel and
aluminum as well as a large glass rear window, has a very
lightweight construction – not only does this reduce the overall
weight of the TT Roadster, it lowers its center of gravity too. It
sleekly blends in with the car's lines and takes up only a small
amount of space when folded down. Thanks to the new Z-fold, the
front section of the roof lies on top of the cloth like a cover. It
locks into place to lie flush with the body, dispensing with the
need for a tonneau cover. The soft top is available in the colors
black and dark grey.
The TT Roadster 3.2 quattro comes as standard with an
electrohydraulically powered soft top, which is available for the
2.0 TFSI as an option. This version of the soft top opens in just 12
seconds at the push of a button, and can even be operated on the
move at speeds of up to 30 mph. The fully automatic hood
incorporates an additional layer of soundproofing beneath the black
headliner for even better acoustic and thermal insulation.
The manually operated roof is operated by means of a central catch.
A mesh wind deflector that extends and retracts electrically can be
ordered as an option to smooth the air stream in the interior – none
of the competitor models are able to offer such a convenient
The body and safety
Like the TT Coupé, the
body of the TT Roadster is also built on the principles of Audi
Space Frame (ASF) technology, featuring a pioneering hybrid
construction that showcases the brand's tremendous expertise in
lightweight design. The body is made from 58 percent aluminum and 42
percent steel. This material mix makes the Roadster extremely light,
with the 2.0 TFSI tipping the scales at just 2,894 lbs. when unladen.
To ensure that the load is distributed evenly between the axles, the
steel components are located principally at the rear of the body –
the bulkhead behind the passenger compartment, for example, is made
from steel. This particular component, which anchors the
high-strength roll-over bars with their elegant plastic covering,
has a fundamental role to play in the body's overall rigidity.
The side sills are also specific to the Roadster: they consist of
extruded aluminum sections containing numerous reinforcing ribs. The
A-pillars have been strengthened too and a high-strength steel tube
integrated into the frame of the windscreen. Already impressive in
the outgoing TT Roadster, static torsional strength has been more
than doubled in the new model – this translates into outstanding
comfort and precision handling.
A full ensemble of restraint systems promise the greatest possible
passive safety. In the event of an impact from the side, aluminum
beams and padding in the doors are called into action along with the
head and thorax side airbags. Two-stage full-size airbags and the
Audi backguard system are on hand to limit the consequences of a
collision from the front and rear respectively.
The interior of the TT
Roadster is noticeably larger too, offering extra headroom and elbow
room. The width at shoulder height is now 53.6 in, an increase of
Deep-set sports seats provide firm lateral support for both the
driver and passenger. The standard-specification leather sports
steering wheel features a flat-bottomed rim. The optional Impulse
leather trim with its distinctive topstitching already attained cult
status when it was offered for the outgoing model; it is one of four
different leather trim packages. The 3.2 quattro is upholstered in a
combined Alcantara/Leather trim as standard.
The three circular air outlets and the dome shrouding the instrument
cluster dials inject the cockpit with characteristic TT flair. As is
to be expected of an Audi, the ergonomic concept is perfect and the
workmanship of the very finest standard. The increase in the body's
dimensions has also benefited luggage space, which has expanded from
210 to 250 litres in both the front-wheel-drive and the quattro
The drive train
Like the TT Coupé, the
new Roadster is available with a choice of two transverse-mounted
engines. Both generate high pulling power and impressive peak
output, resulting in out-and-out sporty performance. The
four-cylinder engine directs its power to the front wheels, while
the V6 powers all four wheels based on the quattro principle
offering dynamism and sure roadholding in equal measure. Apart from
a sporty six-speed manual shift, both engines are also available in
conjunction with the innovative S tronic dual-clutch gearbox for
lightning-fast gear changes without any interruption in the power
The four-cylinder unit bearing the initials TFSI musters up 200 hp
and a constant 207 ft.-lbs. of torque between 1,800 and 5,000 rpm
from its capacity of 1,984 cc. The TFSI technology combines a
turbocharger to optimum effect with Audi's own gasoline direct
injection, which produces a distinct improvement in combustion
In both 2005 and 2006, the responsive and extremely refined
two-liter turbocharged FSI unit was voted "Engine of the Year" by an
international jury of experts.
When fitted with the S tronic shift, the Audi TT Roadster 2.0 TFSI
accelerates from standstill to 62 mph in just 6.5 seconds and
reaches a top speed of 146 mph. It burns an average of just 7.8
litres of fuel for every 100 km.
The V6 unit with its capacity of 3,189 cc delivers 250 hp and a peak
torque of 236 ft.-lbs. which is on tap between 2,500 and 3,000 rpm.
The sonorous, ultra-compact long-stroke engine features two
continuously adjustable camshafts. The TT Roadster 3.2 quattro
sprints from 0 – 62 mph in 5.9 seconds with the S tronic gearbox and
can, if necessary, go on to reach a governed top speed of 155 mph.
It returns average fuel consumption figures of 9.5 l/100 km.
The sporty chassis has
undergone complete redevelopment for the new TT Roadster. Its chief
features are the complex four-link rear suspension, wide track
widths, elastokinematics that have been heavily reworked, plus large
wheels. The 2.0 TFSI rides on 16-inch and the 3.2 quattro on 17-inch
alloy wheels. The wheels may be specified with run-flat capabilities
as an option.
The front wheel suspension, which is linked to a separate subframe,
has a McPherson construction that has been refined by the use of
lightweight aluminum components. The electromechanical
power-assisted steering combines a direct ratio with sensitive
The construction of the four-link rear suspension, which also
operates using a subframe, separates the coil springs and the shock
absorbers from one another. The longitudinal links – which have a
relatively soft set-up for enhanced ride comfort – absorb the
propulsive and braking forces, while the rigid connection of the
three transverse links for each wheel allows them to direct the
lateral forces into the bodyshell with great precision.
The redeveloped electronic stabilization program (ESP) has been
optimized for a sporty driving style and to help produce the
steering balance of the TT Roadster, which varies between neutral
and slight understeer. If necessary, the brake assist system takes
action to ensure that the four large disc brakes build up maximum
braking power as fast as possible.
The optional Audi magnetic ride adaptive damping system is a
high-tech feature that is unique in the roadster segment. At the
push of a button, drivers can choose between either an
extra-comfortable or a decidedly dynamic suspension set-up.
Circulating inside the shock absorber struts is a special fluid
containing minute magnetic particles. Applying a voltage to this
fluid alters its viscosity – and therefore the damping
characteristics – within milliseconds.
All variants of the new
Audi TT Roadster come generously equipped as standard, with the
specification including the new "chorus" audio system and a driver
information system, and in the 3.2 quattro, automatic air
conditioning. There is a choice of two optional navigation systems,
both DVD-based and featuring the exemplary MMI operating logic.
Universal mobile phone preparation and the resonant Bose
surround-sound system are also available.
An extra touch of class can be added to the interior's sophisticated
and sporty ambience by opting for either of the two aluminum styling
packages. The standard storage facilities, featuring deep
compartments in the doors and two cup holders, can be supplemented
with the storage package, comprising three storage nets and four
extra, practical compartments. Customers who lead a sporty, active
lifestyle are also able to opt for a load-through facility in the
rear panel, including a ski bag which is large enough to accommodate
two pairs of skis up to 1.90 m in length – something which no other
model in the roadster segment is able to offer.
Xenon plus headlights with the adaptive light cornering function can
also be found on the extensive list of equipment options. They are
fitted in conjunction with a headlight styling package that Audi
includes as standard on the 3.2 quattro.
