Audi Sport in GT4 racing
Audi Sport customer racing headed for growth
Audi Sport GmbH’s customer racing program has been experiencing rapid
growth. Following Audi Sport’s launch of the Audi R8 LMS GT3 race car in 2009,
the presentation of the second generation of this success model in 2015, and
the RS 3 LMS for the TCR category in 2016, the portfolio of models Audi offers
to customers has been extended once again in 2017. The Audi R8 LMS will be
unveiled in its GT4 variant before the New York International Auto Show on
April 11, 2017. In racing, the production-based GT sports car will make its
public debut in the Nürburgring 24 Hours from May 25 to 28. With that, the
brand will be filling another growing category in international motor racing. The
GT4 class, which originated in Europe, will be intensively marketed on an
international scale starting in 2017, with fielding opportunities available in
North America, Europe, Asia and Australia.
GT racing fascinates an increasingly large fan community. Alongside the popular GT3
category the GT4 class is extending its presence on a global scale starting in 2017.
Audi Sport has developed a new customer racing model for this promising category –
the R8 LMS GT4. The GT3 model’s “little brother” reflects an even closer orientation
to the Audi R8 Coupé *, shares more than 60 percent of its assemblies with the roadapproved sports car, and is produced at the Böllinger Höfe site in Germany, as well.
As a result, Audi creates synergies from which the customers of the new race car will
benefit in terms of purchasing cost and cost of ownership.
Audi is developing the GT 4 model, which can deliver up to 364 kW (495 HP) of
rating-dependent power output, in the course of the 2017 season before achieving a
final homologation state and requesting approval for racing. During the second half of
the year, the team of Chris Reinke, Head of Audi Sport customer racing, will be
preparing the production of the race car so that the new Audi R8 LMS GT4 can start
to be handed over to customers by the end of the year.
For the R8 LMS GT4, Audi Sport draws on an extensive global network of services,
spare parts logistics and professional support. Audi Sport customer racing has
established this infrastructure for the GT3 project on four continents and will be using
this proven network for the GT4 model range as well.

Interview with Chris Reinke
“Numerous synergistic effects benefit the customer”
Chris Reinke has been Head of Audi Sport customer racing since 2016 and
sees major growth potential in the GT4 category.
Just shortly following the R8 LMS (2015) and the RS 3 LMS (2016), Audi Sport
GmbH is presenting the R8 LMS GT4 in April 2017. What are your expectations
of the new model?
Since 2009, we have delivered more than 200 units of the R8 LMS and are ranking
among the leading brands in the global GT3 market that keeps growing. The Audi RS
3 LMS we’ve been offering since November 2016 has been meeting with tremendous
response by customers in TCR touring car racing. The new Audi R8 LMS GT4
perfectly fills the gap in between, as GT4 racing is the ideal stage for gentlemen and
amateurs that would like to race sports cars but find GT3 racing to be too complex.
The Audi R8 LMS GT4 is a production-based sports car. What does that mean?
First of all, the regulations do not permit any major variations from the production
standard. As a result, it’s particularly beneficial for a model to have the qualities that
the Audi R8 V10 already brings to the track from the factory. This powerful and
balanced base makes it possible for us to manufacture the production and the race
cars at the same facilities. Accounting for more than 60 percent, the number of
shared components is even higher than those between the GT3 model and the
production sports car, about half of which are identical. By the way, the GT4 sports
car also benefits from the experiences we’ve been gaining with the Audi R8 LMS
across two generations. In aspects of safety, we’ve adopted the standard.
Are there any other synergies?
The Audi R8 LMS GT4 perfectly fits our customer sports kit – in terms of technology
and logistics. In addition to the close linking with production, we even use the same
parts as in the GT3 race car. For support and logistics we utilize the same network as
the global GT3 program. The GT4 market is seeing rapid development in the
important regions of North America, Europe, Asia and Australia, with highly attractive
business potential for us. The numerous synergistic effects are positive for the
customers as well because the economic aspects of the race car are very attractive –
both in terms of purchasing cost and cost of ownership.

Audi R8 LMS GT4
Dynamic, customer-friendly and safe
The Audi R8 LMS GT4 stands for production-based racing. The race car that is
directly derived from the road-approved Audi R8 Coupé V10 is powerful, offers
a high level of safety yet remains economical in terms of purchasing cost and
cost of ownership. It is the ideal race car for amateur campaigners, completely
in line with the spirit of the GT4 regulations carrying on a great sports car
tradition in which fascinating road-going sports cars were a popular base for
GT racing more than half a century ago.
A veritable powerhouse: The V10 engine of the new Audi R8 LMS GT4 can deliver up
to 364 kW (495 HP) – depending on the applicable Balance of Performance rating
that is designed to ensure fair competition between all race cars. The 5.2-liter
naturally aspirated engine is produced by Audi Hungaria at the Győr location and only
receives a new exhaust system, the restrictor plate prescribed by the regulations and
modified mapping of the production-level electronic control unit (ECU). Audi Sport has
previously demonstrated the durability of this unit, which requires maintenance only
after 10,000 kilometers and rebuild after 20,000 kilometers, in the GT3 model.
Afterwards, many customers complete additional cycles in racing operation.
As quattro four-wheel drive is prohibited in the GT4 class, Audi Sport utilizes a 7speed double-clutch transmission combined with rear-wheel drive. Two
electrohydraulically operated wet-type multi-plate clutches ensure shortest shifting
events without tractive force interruption. A mechanical limited slip differential is used
on the rear axle.
The suspension of the road-going version featuring double wishbones on all four
wheels offers perfect prerequisites for racing. Rebound and compression adjustable
racing-specific dampers and springs, as well as adjustable stabilizers, complete the
suspension system. A new steel disc braking system with modified brake calipers in
combination with the production-level ABS control system ensures optimum
deceleration. Special brake cooling ducts at the front and rear guarantee braking
stability also in racing. For the steering system, Audi Sport has adopted the hydraulic
rack-and-pinion unit from the GT3 model, albeit with an electrically operated pump. In
spite of the cost benefits offered by the 5-hole cast aluminum wheels they have been

specifically designed for racing purposes. Audi Sport also offers a tire pressure
warning system as an option.
In terms of passive safety, Audi Sport again sets high standards. In addition to
standard equipment such as a fire extinguishing system, safety nets for the driver and
crash foam in the doors, Audi Sport exceeds the minimum requirements in many
areas. The Audi Sport customer racing PS3 safety seat represents the most recent
evolution of the PS1 model. It is standard equipment in the GT4 model as well as in
the Audi customer racing models for GT3 and TCR racing. The safety nets are
attached to the seats for optimum connection, and the 6-point harness corresponds to
the GT3 standard. The longitudinal adjustment of the seat combined with the axial
and height adjustment of the steering wheel are optimally suited for drivers of diverse
body height. A roof hatch facilitates rescue operations following an accident. To
reduce the loads acting on the driver’s spinal column, the helmet can be removed
upward and a Kendrick Extrication Device applied. Inside the car, the steel safety
cage is mounted at six points to the Audi Space Frame (ASF) featuring an aluminumCFRP mixed-material construction, plus there are two connections to engine bay
braces. The FT3 safety fuel cell is filled using a dripless rapid-refueling system for
racing.
In the ergonomically designed cockpit, the driver can activate and adjust various
driving functions via the steering wheel and the center console. A central multifunction display within the driver’s view and a data logger create transparency with
respect to operating conditions and data analysis.
The body components are largely identical to those of the production car but have
been optimized to support the race car’s aerodynamics and thermal management of
the cooling and braking systems. The GT4 race car is closely oriented to the
production model. Its chassis is produced at the same manufacturing facilities as the
one of its road-approved sibling. Consequently, there are synergies for the Audi R8
LMS GT4 in terms of production and the Group-wide pool of components as well as
service and maintenance – directly benefiting the customers.

The GT4 category
A sports car class loaded with potential
The GT4 category will be invigorated starting in 2017. That is when the SRO
Motorsports Group is going to introduce this race car class, which has existed
since 2007, in new racing series and systematically market it around the globe.
The concept of the GT4 class uniquely addresses privateer drivers. Minor
modifications of the production model and affordable purchasing and ownership costs
clearly distinguish this category from more complex, faster and more expensive GT3
models. As a result, the GT4 class lends itself as an attractive road-going sports car
category that is ideally tailored to meet the needs of amateur campaigners.
In terms of technology, there are hardly any modifications permitted to the race cars
compared with the base models, and the materials of the bodywork have to
correspond to those used in the production-level components. There are only few
areas for which the SRO grants waivers on request. This has two advantages. Only
individual component assemblies may be optimized by racing-specific designs, which
is a rule that supports a level playing field. At the same time, the race car’s proximity
to the production model prevents an escalation of costs, as the regulations prohibit
the development and homologation of generally more complex technology. For
instance, the manufacturers have to submit reference parts for various areas such as
the electronic control units of the engine, transmission and ABS braking system. This
ensures that a comparison with the production model can be made at any time.
The major breakthrough for the GT4 category in 2017 going forward will result from
intensive marketing activities. The SRO Motorsports Group is in the process of
introducing this class in a large number of regions and countries, promoting existing
GT4 competitions in the process and has created global fielding opportunities through
international agreements. In Europe, for example, a North and South classification will
be introduced. The French GT Championship from 2017 on will exclusively rely on
GT4 models. In the United Kingdom, Italy, Australia and China, plus in the new
Blancpain GT Series Asia, they are part of a more comprehensive GT field. In North
America, the two major sports car series, the IMSA Continental Tire Sportscar
Challenge and the Pirelli World Challenge, are additionally opening their fields to the
GT4 models. Other series, such as the VLN in Germany and the 24-Hour Endurance
Series, complete the list.

Audi Sport customer racing
GT3, Audi Sport TT Cup, TCR and now GT4
Audi Sport has been active in international GT3 racing since 2009 and is
ranking among the global players in this growth market. Audi Sport customer
racing is responsible for the brand’s customer racing program. It is firmly
rooted on four continents, has won dozens of international titles and long
achieved three-digit production figures. Audi Sport has produced more than
200 R8 LMS cars to date.
"Audi Sport has become a truly global player," says Stephan Winkelmann, Managing
Director of Audi Sport GmbH. "Our customer racing cars in the highly competitive
GT3 market have already exceeded 200 examples and these have collected
numerous trophies and titles. In addition to GT3, we have extended the product
portfolio even further by entering TCR competition and now the GT4 category as well,
two growing formulas offering our customers more worldwide racing opportunities. In
doing so, the brand of Audi Sport is becoming even more prominent. The new GT4
car further emphasises the connection between our road and race car technology. 60
percent of the components in the Audi R8 LMS GT4 are shared with its road-going
sibling.”
In the Audi Sport TT Cup launched in 2015, Audi Sport customer racing offers young
talents an opportunity to enter motorsport with Audi as well. The vehicles in this onemake cup are centrally fielded by Audi Sport and are not for sale. In 2016, Audi
customer racing premiered the Audi RS 3 LMS as an entry-level race car available
directly from the factory, combined with support similar to the one its GT3 customers
are accustomed to. Of major benefit is the fact that the Volkswagen Group with Audi,
SEAT and Volkswagen is represented in the TCR three times and, as a result, has
logistic advantages in supporting customers.
Now, the Audi R8 LMS GT4 fills the gap between the RS 3 LMS and the R8 LMS.
During the 2017 season, Audi Sport is developing the mid-engine sports car to be
ready for use in racing, followed by the production launch in the second half of the
year. Starting at the end of the year, customers around the globe will be able to order
the production-based sports car. “With that, we’re covering a wide range from a onemake cup for up-and-coming drivers through to top-flight GT3 racing,” says Chris
Reinke, Head of Audi Sport customer racing.
