capable of in excess of 65mpg with CO2 output of just 114g/km, 0-62mph in
7.3 seconds, top speed 147mph Open minds at Audi have again been applied to
the classic concept of the open-top two-seater sports car, and the result
– the all-new TT Roadster – is set to bring its thoroughly
contemporary perspective on the time-honoured theme to next month’s
Mondial de l’Automobile in Paris.

While on the outside it retains a fast-retracting fabric hood in
accordance with roadster tradition and in the interest of weight
minimisation, the third generation of the Audi icon embraces the future in
all other respects, from its advanced hybrid aluminium and steel
construction to its remarkable all-digital virtual cockpit and advanced new
chassis with upgraded quattro drive. The new high performance convertible
is set to arrive in the UK in good time for spring 2015, and will be
available to order from mid-November priced from 31,955 OTR.

“The concept of designing a compact roadster following clear
geometrical rules formed the original idea for the Audi TT in autumn
1994,” says Prof. Dr. Ulrich Hackenberg, Board Member for Technical
Development at AUDI AG: “From the first generation on, it has been a
sports car for the senses – a driving machine with an authentic
design. With the new TT Roadster, we have developed this concept in a
consistent manner and further improved the technical experience in the car
with innovations such as the Audi virtual cockpit.”

The new TT Roadster offers the capabilities of a sports car with the
option of added open-top exhilaration, but without the compromises that
this blend of attributes often demands. Great importance has been attached
to torsional rigidity and ride comfort, and specially developed struts in
the underbody and body work in their favour. Aerodynamics have also been
prioritised, the new Roadster slipping cleanly and quietly through the air
with a best-in-class drag coefficient of 0.30.

More purposeful stance

At 4,177 millimeters in length the two‑seater is 21 millimetres
shorter than its predecessor. Its wheelbase, on the other hand, has grown
by 37 millimetres to 2,505 millimetres, contributing to shorter overhangs
for an even more purposeful stance. With a width of 1,832 millimetres, the
new TT Roadster is 10 millimetres narrower than its predecessor, and at a
height of 1,355 millimetres it is 3 millimetres lower.

The front of the open‑top sports car conveys power and energy
through its accentuated horizontal lines. Similar to the Audi R8, the
Singleframe grille is wide and flat, and the four rings are positioned on
the bonnet in the style of a high-performance sports car. On the standard
version, the air inlets are connected to one another and divided by two
vertical slats.

Two vertical lighting elements are also positioned in the headlights and
emit the LED daytime running lights. In the UK these are combined with
either xenon or LED headlamps depending on version, and in both cases it
will be possible to upgrade these to new Matrix LED headlamps which can
automatically divert their high beams around oncoming and leading traffic,
and also feature dynamic indicators with a sweeping function following the
intended turn direction.

The flat and taut top of the new TT Roadster and the TTS Roadster also
provides a clear contrast with the body and is defined by the short side
window design that is typical of the TT Roadster. When viewed from the
side, many of the details invoke the first generation of the design
classic. The shoulders have a muscular look and the sill contour forms a
strong light-refracting edge. The broad wheel arches form their own
geometric entities: The front wheel arch breaks through the bonnet gap that
continues as the tornado line all the way to the rear end.

At the rear, horizontal lines again underscore the width of the
open‑top sports car. The bars in the standard LED rear lights, which
adopt the motif of the headlights, are permanently illuminated. The third
brake light – a flat strip on the edge of the luggage compartment lid
– connects the light silhouette at the rear. A diffuser incorporates
the tailpipes of the exhaust system. At speeds of 74mph and above, a
spoiler is electrically extended from the luggage compartment lid to
provide additional downforce on the rear axle.

The sleek new body can be painted in a far more distinct and varied
range of colours than its predecessor. There are 10 exterior colours, one
of which is exclusively reserved for the S line. Five of the colours in the
palette are new for the TT, and two of these are completely new for Audi:
nano grey and tango red. Panther black, crystal effect and the expressive
Sepang blue are also available for the TTS.

Quieter and lighter

As with all Audi Cabriolet models, the new TT Roadster and TTS Roadster
also feature an electrically actuated fabric top. Every version benefits as
standard from the more insulating acoustic top with its extremely effective
thermal insulation and low noise level, especially in the frequency range
of the airflow. The thick fleece layer on the black inner headlining adds
comfort. Depending on frequency, the noise level in the interior has been
reduced by up to 6 dB compared with the previous TT Roadster.

The snug fabric top is available as standard in a selection of colours
including black, biege and titanium grey, and its magnesium, aluminium,
steel and plastic framework keeps its weight down to just 39 kilograms – 3
kilograms less than its predecessor. This has a positive impact on the
gross vehicle weight and on the centre of gravity.

The two electric motors powering the soft-top complete the opening and
closing process in 10 seconds, and can do so at speeds of up to 31mph.
While opening, the top forms a Z shape as it folds flat into its aluminium
tray, which doesn’t encroach on the 280 litre luggage compartment.
Sophisticated clamping technology ensures that the closed top is completely
taut even at high speeds. An electrically powered mesh wind deflector can
also be specified as an option.

Audi Space Frame evolution

The body of the TT Roadster and the TTS Roadster represents a new
evolution of the Audi Space Frame (ASF) based on the modular transverse
matrix (MQB). Ultra-high-strength components made from hot-shaped steel
reinforce the front section and the passenger compartment floor. The
passenger compartment and all outer skin and attachment parts are made of
semi-finished aluminium in the form of cast nodes, extruded profiles and
sheet metal.

As a result of this extremely sophisticated construction process the
entry level petrol-powered TT Roadster with its 2.0 TFSI engine and manual
transmission weighs in at just 1,320 kilograms.

Compared with the Coup, the body of the Roadster has been modified in
important areas. The aluminium A‑pillars each conceal a second steel
pillar in their interior, which in turn houses a solid steel tube. Internal
steel ribbing ensures the aluminium sills have high-strength properties.
V‑shaped steel struts reinforce the zones underneath the engine
compartment and the luggage compartment, and connect the axle carriers.

In the TT Roadster and the TTS Roadster, a solid wall consisting of two
box profiles separates the interior from the luggage compartment, and
replaces the bottom cross member found on the Coup. The upper area of this
wall houses the sleek, rounded steel roll-over bars. Mounting plates seal
the openings in the rear wall, which features through-loading as

The new TT Roadster launches with two turbocharged four-cylinder engines
– a TDI and a TFSI – leaving the most powerful four-cylinder TFSI for
the TTS Roadster. With power outputs of between 184PS and 310PS, they
clearly surpass their respective predecessors in terms of power, while also
significantly improving on their efficiency. All meet the Euro 6 standard,
and all are linked to a start-stop system as standard.

ultra model offers up to 65.7mpg

Featuring 184PS and 380 Nm (280.3 lb‑ft) of torque, the 2.0 TDI
ultra combines great strength with remarkable restraint where economy is
concerned – it can return up to 65.7mpg, which equates to CO2
emissions of 114 grams per kilometre – a new benchmark in its

The 2.0 TFSI produces 230PS and 370 Nm (272.9 lb‑ft) of torque in
the TT Roadster; in the TTS Roadster, output rises to 310PS and 380 Nm
(280.3 lb‑ft). The top model sprints from 0-62mph in just 4.9 seconds
on its way to an electronically governed top speed of 155mph. Switchable
flaps in its exhaust system can be controlled via the standard Audi drive
select driving dynamics system to underscore the sonorous sound.

In the TT Roadster the high-tech petrol unit is initially combined with
either front-wheel-drive and a six-speed manual gearbox or quattro
all-wheel-drive and a six-speed S tronic twin-clutch transmission. The TTS
Roadster, with standard quattro drive, also features a manual gearbox or
the option of S tronic. The dual-clutch transmission shifts rapidly through
the gears without any noticeable break in propulsive power and can be
controlled by paddles on the steering wheel if desired. In efficiency mode
in the Audi drive select system, the S tronic coasts when the driver takes
his or her foot off the throttle pedal.

The quattro permanent all-wheel drive system has been fully redeveloped.
During regular driving, its electrohydraulic multi-plate clutch optimally
distributes the drive torque between the front and rear axle depending on
driving conditions, road characteristics and driving style.

The new configuration elevates driving enjoyment and safety to a new
level through electronic clutch management. More power is routed to the
rear axle during more committed driving, literally propelling the new TT
Roadster and the TTS Roadster into corners. Safe, controlled drifts are
possible on low-friction surfaces.

Audi drive select with five modes

The third TT generation is the first to network permanent
all-wheel-drive with the Audi drive select driving dynamics system, which
in the UK is standard across the range. The driver can use this to
influence engine characteristics and the operation of the steering by
toggling between Comfort, Auto, Dynamic, Efficiency and Individual modes.
Audi drive select can also be used to alter the operating parameters of a
number of optional systems including the S tronic transmission and Audi
magnetic ride (fitted as standard on the TTS Roadster).

Magnetic ride employs synthetic hydrocarbon oil containing
microscopically small magnetic particles circulating within the damper
pistons. When a voltage is applied to a coil, a magnetic field is generated
in which the alignment of the particles changes so that they are
perpendicular to the oil flow, thereby inhibiting its flow through the
shock absorber channels.

The control unit continuously analyses the driving properties and the
condition of the road. Depending on the setting in Audi drive select, it
can favour comfort or tautness and composure depending on the
driver’s preference. Targeted bracing of the individual wheels pins
the Roadster tightly to the road, largely suppressing roll, making steering
response even more rapid and reducing pitch during braking.

The chassis with which Audi magnetic ride works so seamlessly also
reflects the technological expertise behind the new Audi TT. The front
suspension is based on a MacPherson system, and integrates aluminium
components which reduce the weight of the unsprung chassis masses. The
four-link rear suspension can process the longitudinal and transverse
forces separately.

New progressive steering system

A progressive steering system is another technical highlight and is
fitted as standard to all versions – its rack is set up in such a way
that the ratio becomes more direct as the steering wheel is turned,
enabling the TT Roadster to be steered precisely with little movement of
the steering wheel in urban traffic and on winding country roads. The
highly efficient, electromechanically driven steering adapts its assistance
to speed and forms the basis for the Audi active lane assist system which
is standard for the TT Roadster 2.0 TFSI, and for the various park assist

Brakes that can be precisely metered and convey a taut pedal feel are
located behind the large wheels. The vented front discs have a diameter of
between 312 and 338 millimetres depending on the engine version. The TTS
Roadster features newly developed, particularly lightweight aluminium
fixed-caliper brakes on the front axle. Another innovation, the
electromechanical parking brake, acts on the rear wheels regardless of
engine version.

The Electronic Stabilisation Control (ESC), which can be switched off
either partly or completely, perfectly complements the car’s agile
handling. Wheel-selective torque control takes effect when cornering: Where
necessary, it can distribute the drive torque from the front wheel on the
inside of a bend to the front wheel on the outside of the bend (in the case
of front‑wheel drive). With quattro drive, it can also perform this
function on the rear wheels. The car turns very easily into the bend thanks
to the difference in propulsive forces, which is helpful for the driver.
Sports mode facilitates particularly dynamic driving, facilitating steering
and control when drifting.

The two-seat interior of the new TT Roadster and the new TTS Roadster
fits around the driver like a custom-made suit. It has an intimate and
protective feel, particularly when the fabric top is closed, without ever
being restrictive. The kerb clearance is high and the newly developed sport
seats with integrated head restraints are mounted low. Together, they weigh
five kilograms less than the seats in the previous TT Roadster. Super
sports seats with integrated head restraints and more pronounced bolsters
are available as an option (standard in the TTS Roadster), and these can
also be supplemented with a head level heating system for optimal comfort
during top-down driving in cooler conditions.

Audi virtual cockpit for all versions

Two specification levels – Sport and S line – will initially
be offered in the UK for the TT Roadster. Both include the Audi virtual
cockpit, which is based around a 12.3-inch, high resolution LCD display
that completely fills the driver’s instrument binnacle and replaces
the traditional analogue dials. Its brilliantly sharp images are courtesy
of a powerful Tegra 30 graphics processor from Nvidia’s Tegra 3

Drivers can choose between two display modes: In the classic view, the
speedometer and rev counter are in the foreground; in
“infotainment” mode the virtual instruments are smaller. The
space that becomes free as a result provides ample room for other
functions, such as the navigation map. At the lower edge of the Audi
virtual cockpit, the displays for outside temperature, time and mileage are
permanently visible. Warning or information symbols are also displayed

Sport models also come equipped with the Multi Media Interface with the
MMI touch pad for fingertip data entry, navigation preparation, Audi Music
Interface and Bluetooth connectivity, the Audi drive select adaptive
dynamics system and keyless go. More comfort-oriented standard features
include Alcantara and leather combination upholstery for the sports seats
and manual air conditioning with controls thoughtfully positioned within
the air vents themselves for space efficiency and convenience. Outside the
cabin, 18-inch 10-spoke alloy wheels, sports suspension and xenon headlamps
with LED daytime running lights all also feature as standard.

The TT Roadster S line upgrades to larger 19-inch alloy wheels with a
five-arm star design, all-weather LED headlights and LED tail lights
flanked by dynamic rear indicators with a directional sweeping function and
S line body styling. It also offers particularly committed drivers the no
cost option to swap to tauter S line sports suspension bringing a further
10mm reduction in ride height.

The interior offers a new palette of colours. There are three to choose
from for both the TT and the TTS – black, rock grey and palomino
brown. For the first time, customers can choose a second colour –
rotor gray with contrasting stitching – in combination with S line
specification, which until now has included an exclusively black interior
finish. TTS buyers can also choose the sporty leather shade express

The cabin of the new TTS includes extended interior elements that add
individually selectable colour accents to the trims of the S sport seats,
the sides of the centre console and the rings of the air vents. For the TTS
specifically, Audi designers have also developed an innovative technical
laser texture for the wings of the dashboard. This texture has a
honeycomb-like, slightly raised structure that gives it even more sporting

Numerous customisation options are also available, including upholstery
in various grades of cloth, Alcantara and leather and three leather
packages. The design selection admiral blue is a particular highlight,
making an impression with matching leather colours, alternately contrasting
stitching, dark aluminium, a coordinated paint finish and a special mesh
floor mat.

High-speed in-car Internet

From the options list, even more of the remarkable Audi virtual
cockpit’s potential can be unlocked by the Technology Package, which
includes hard disk-based navigation mapping that can completely fill the
12.3-inch TFT monitor, and also beams the Internet to the car via Audi
connect using the latest, high-speed LTE (Long Term Evolution)
communication standard.

This brings features such as Google Maps, Google Street View, Audi
traffic information online, price-graded refuelling locations in the
vicinity and the latest news, flight and train information to streamline
every journey. It also adds Audi music stream and access to social media
services such as Facebook and Twitter. For sound that is as
attention-grabbing as the cabin’s visuals, a 680-watt, twelve-speaker
Bang Olufsen audio system can be specified in addition.

The optional driver assistance systems are equally sophisticated. The
Audi side assist system ensures safe lane changes with a radar measurement
towards the rear, and the Audi active lane assist (standard on 2.0 TFSI
engines) keeps the open-top two-seater in its lane with minor steering
interventions. The park assist system with display of surroundings
automatically pilots the car into and out of parking spaces. Traffic sign
recognition is another optional system.
