The maddest Porsche is handmade!
Porsche 911 RSR
To compete for the 2019 FIA World Endurance
Championship (WEC), Porsche has used a lot of successful experience from active
racing to create the new 2019 Porsche 911 RSR, which is up to 95% new. With the
classic natural intake engine, increased displacement and other new designs,
the very powerful car will become stronger. Fritz Enzinger, vice president of
Porsche Motorsports said that since 2017, the Porsche 911 RSR has won more
than 20 victories in the World Championships and in the endurance races in
North America and Europe. The Porsche is located in the Weissach R&D
center. Full-scale evolution will replace the current racing car that won the
WEC Team and Driver Doubles Championship, the French Le Mans Classic, the North
American Endurance Race IMSA Champion and the Petit Le Mans (PLM) Champion.

1. Equipped with NA engine to
increase the displacement
In terms of powertrain, Porsche follows the high-performance
tradition and the latest generation 911 uses a six-cylinder
horizontal-on-the-basin natural intake engine. The engine with the displacement
increased to 4,194c.c. is located in front of the rear axle. According to the
different specifications of each race, the maximum horsepower falls on the
515hp spectrum, which is also the maximum exhaust level of the factory car.
Compared to the previous 4-liter engine, it delivers more saturable power over
a wider range of speeds. With the lightweight six-speed sequential gear ratio,
the new 911 RSR can shift gears with greater efficiency. The bilateral
exhaust pipe is placed in front of the two rear wheels, which not only reduces
the weight of the exhaust system but also effectively uses aerodynamics to
improve performance.
After modifying the configuration of the exhaust system, the
rear space accommodates the newly designed tail deflector. The new rear tail
deflector provides greater downforce for the Porsche 911 RSR at high speeds.
The front and side-side diversion design after the wind tunnel adjustment makes
the stability of the high-speed driving increase, so that the tire consumption
during the competition can achieve better durability.

2. Plus the same level of protection
structure as F1
Vehicle handling and serviceability are key factors in the
endurance race. These projects became the focus of development when developing
a new generation of 911 RSRs. The entire cockpit environment has been
redesigned to allow drivers to focus on the race in the most unburdened
situation. Therefore, the driving experience provided by the driver becomes a piece of very important information in the development process. The body part is made of
a carbon-fiber structure much larger than the previous generation. If there is
a need to change the body during the endurance race, it can greatly reduce the
maintenance work and strive for more precious time.
To protect the driver to a higher degree, the
active and passive safety equipment is fully upgraded. The collision warning
system can assist the driver in identifying the prototype car that is
approaching at a high speed from the rear so that the driver can respond
earlier. In addition to strengthening the anti-roll cage, the body structure is
more suitable for the FIA side impact structure of the same level as Formula
1, and for the impact protection of the driver's legs. Also, the
detachable roof structure and the six-point seat belt racing seat are all
designed for the safety of racing cars.

structure and the six-point seat belt racing seat are all designed for the
safety of racing cars.
3. 95% new development of the whole
vehicle
Pascal Zurlinden, GT Racing Team Director, emphasized that
the team conducted a comprehensive analysis of all the factory teams and
private teams that used the Porsche 911 RSR as a participating vehicle to
identify areas for improvement that could be upgraded. We have also made
significant progress in the development of the new specifications for the next
three years of racing certification, especially in the areas of racing
performance, efficiency, durability, and ease of maintenance. More precisely,
95% of the entire vehicle is newly developed, and the parts that continue to
use the self-employed models are only headlights, brake systems, clutches,
driver seats and some suspension system components.
Pascal Zurlinden explains that the development of the new
Porsche 911 RSR started in 2017, and the first conceptual design was a
computer-assisted soft gymnastic. In August 2018, the first road test was
conducted at the Porsche Test Track in Weiss. In the next few months, the team
conducted a series of more rigorous tests on the car, which was then taken over
by the factory's experienced test drivers and engineers. At the same time as
these tests were carried out, the research and development of the car body
aerodynamics of the performance of the car were also in full swing. In March
2019, the WEC and IMSA event team were assembled and a 30-hour endurance test
was conducted on the Le Castellet. After 6,000 km of speed, the vehicle did not
encounter any technical obstacles. The driver and the engineer performed
extremely well. Satisfied, this car officially won the FIA endurance
certification on July 1, 2019.

the adjustment makes the Porsche 911 RSR have high stability during high-speed
driving, which makes the tire consumption during the competition reach
better durability.
4. Premier Goodwood Premiere
The most striking 911 in history was officially unveiled at
the Goodwood Festival of Speed, the annual performance event held in the UK on July
6, 2019. The official first stop of the Porsche 911 RSR will be the WEC opening
of the new season on September 1, 2019, at the Silverstone circuit. Before the
start of the next season, active racing cars and drivers will participate in
the FIA WEC GTE-Pro group event. The eight-day double-day event will be held
by the Barcelona event (July 23 and 24). The Porsche GT Team will be Michael
Christensen (Denmark) and Kévin Estre (France) attacked side by side, while
Gianmaria Bruni (Italy) and Richard Lietz (Austria) also drove another car. The
new car will be used in the 2020 season of the IMSA WeatherTech SportsCar
Championship. In this North American event, the factory will also send two
Porsche 911 RSRs to participate in the GTLM group. The private team will use
the new Porsche 911 RSR from the 2020/2021 FIA WEC season.
5. The first two cars are painted
differently.
The new Porsche 911 RSR also pioneered the use of different
racing cars for the two participating vehicles, but the No. 91 vehicle was still
painted with Porsche racing white. And a red flow line is applied throughout
the center of the vehicle, and the same red paint can be seen on the side of
the vehicle. The flow waistline and body of the car are highlighted in gray.
The No. 92 car was used to reverse the gray and white areas used in the No. 91
car, creating different styles of painted cars and changing the tail to all
black, making it easier to identify the 91 and 92 cars.
