GTE – PORSCHE 911 RSR


P


orsche used the Goodwood Festival
of Speed in July to launch its new
Le Mans contender, a racecar which
sure does have a lot to live up to. Its
predecessor, launched just two years ago, has
won the world championship title in both GTE
Pro and Am this year and is on course to secure
the titles in the IMSA series in the US. It was also
victorious at Le Mans in 2018.
Little wonder then that some suggest it is
probably good enough to do another year, and
they may be right. But Porsche did not want to
stand still and in the 2019 version of the 911
RSR GTE it has developed a car that is ’95 per
cent’ new, according to director of GT Factory
Motorsport at Porsche, Pascal Zurlinden.
Fundamentally, though, it is still similar to
its predecessor, although the team has targeted
driveability and reliability as its development
focus. To this end it had already completed a
30-hour test and more than 6000km of track
running before it was launched. It made its
track debut at the WEC pre-season test in
Barcelona in July, and will race for the first
time at Silverstone for the opening race of the
2019/20 season at the beginning of September.
The US debut will be in Daytona in January.

The launch of the new Porsche comes at
an interesting time for the category, a time of
change and also uncertainty, which has led to
both McLaren and Lamborghini pulling the
plug on planned GTE programmes. Much of
this uncertainty is to do with the regulations,
particularly in the top class in the WEC. There
was actually a proposal to make the GTE cars
the top class, removing their restrictions based
around the BoP, but this has been rejected in
favour of the new hypercar concept. This has
also had a dramatic impact on the GTE class, as
hypercars is essentially now the top GT category,
as it based on road-going dream cars.

Class warfare
This has left the GTE category in something of
a quandary. Not only is it expensive, factory
racing, but it is now not even the top GT class,
and so questions at board level are sure to be
asked. BMW and Ford have both stopped their
GTE programmes in the world championship
(although they are continuing in the IMSA
series at least until the end of this year and
BMW has not signalled an intent to leave the
class). Aston Martin has announced that it will
support the new hypercar top class with its

Valkyrie, which calls into question the future
of its Vantage GTE programme, while Ferrari
continues to run its GTE programme through
its Corsa Clienti division, which is for customers,
and is not a full factory effort.
More positively, Corvette is expected to
launch its new contender before the end of the
year, and we expect to see it racing next season,
while Porsche has bitten the bullet and created
the car featured here in time for the 2019/
FIA WEC season. These are strange times for
the category that has proven to be the best in
manufacturer motorsport for many years, then,
and the threat to GTE comes not only from
above, with the hypercar, but also from below,
with GT3 regulations now becoming more
robust, as this enjoys manufacturer interest
at some of the biggest races in the world,
including the Spa 24 hours where almost half
the grid was full factory participation.

Transatlantic racer
So as things stand Porsche is the only marque
committed to the GTE category on both sides
of the Atlantic. It will run two cars in the WEC
and another two in IMSA, and has had to design
its 911s with versatility in mind, catering to the

The new 911 GTE car completed a 30-hour test at Paul Ricard in June, racking up 6000kms without any technical problems. It will make its race debut at Silverstone in September
