The Porsche 911 GT2 is a high-performance sports car built by the German manufacturer Porsche from 1993 to 1998, 2001 to 2005, 2007 to 2012, and then since 2018 (as the "GT2 RS").
 It was based on the 911 Turbo, and uses a similar twin-turbocharged engine, but features numerous upgrades, including engine upgrades, larger brakes, and stiffer suspension calibration.
 The GT2 is significantly lighter than the Turbo due to its use of rear-wheel-drive instead of all-wheel-drive, and the lightening or removal of interior components.
 As a result, the GT2 is the most expensive and the highest trim level within the 911 lineup.
The 2013 Porsche Mobil 1 Supercup season was the 21st Porsche Supercup season.

 Its discontinuation marked the end of air-cooled Porsches, with the 993 being the last air-cooled 911.
 The 993 generation of the 911 is often referred to as the best and most desirable of the 911 series, not only because of its beauty, but also because its performance is very good, even by modern standards, and the 993 was "the last complete 'modern classic'"; "the 993 was and forever will be that last fresh breath of air that Porsche gave the world; elegance and muscle all in one package."
 The book "Porsche 993 - Essential Companion" refers to the 993 as the "King of Porsche," and it is generally acknowledged as "The purists' Holy Grail."
