Porsche Mobil 1 Supercup.
racing teams, which use two to three
race cars in the championship. Each
race covers a distance of approximately
70 kilometres. The drivers, which include
established personalities alongside
promising new talent, give everything
they have from start to finish. After all,
another prize might just be up for grabs:
a career in top level GT racing, for
example.

The level playing field is provided by
the car: the new Porsche 911 GT3 Cup.
Porsche AG takes care of the organisation, while the specialists of
Porsche Motorsport offer professional

top level.
Drama – with drivers pushing themselves
to the limit. Passion – among the teams,
partners and sponsors. As the most
exacting series of the 20 Porsche One-
Make-Series staged around the world, the
Porsche Mobil 1 Supercup not only offers
utterly electrifying excitement, it has also
established itself as an excellent business
and marketing platform in international
motorsports. Since 1993, the Porsche
Mobil 1 Supercup has been held as part of
the FIA Formula 1 World Championship –
and as the only Gran Turismo race series.

International One-Make-Series.
Like their German equivalent, these series
in many countries provide support races
for prestigious highlights of the
motorsports calendar, including the BTCC
and the FIA WEC. Races are held on
almost every weekend of the motorsports
season. The passion to win fuels the fight
for every hundredth of a second: young
upstarts challenge old hands, while
amateurs compete with professionals.
Encounters that promise sheer racing
excitement.
From the fastest One-Make-Series in
Germany to the top international event.
Since the Porsche Carrera Cup Germany
was held for the first time back in 1990,
a number of international spin- offs would
soon establish themselves. Today, the
drivers and teams compete against each
other with their Porsche 911 GT3 Cup in
29 countries across five continents: from
Brazil to China, from Australia to Finland,
and from the Middle East to North
America. Those who make it here can fight their
way to the very top. The same
philosophy applies: equal opportunities for
every competitor. This is guaranteed by
uniform rules and technically identical
Porsche 911 GT3 Cup cars. Only the
vehicle setup is allowed to be determined
by the teams themselves. In true keeping
with the motto ‘May the best man win’.

As a result, the power to tip the balance
rests solely in the hands of the drivers
and teams.
