Porsche 911 GT2: the definitive history of the “evil twin” of the Porsche 911 Turbo
In the early 90s, Porsche was completely different from the giant corporation that is today company. Its model range was very limited, and in 1993, sales fell below 14,000 units - today exceed 200,000 cars annually loosely. Still, it was a brand very committed to competition, and he devoted a large part of their scarce development funds to hire. Despite being on the verge of bankruptcy, they drew strength from weakness, and initiated a ambitious racing program-client focused on the newly created category GT2 FIA.
By then, 993 were the core of the 911 range, the last air-cooled sports brand Zuffenhausen. Let's take a little trip in time to 1995. Before that Porsche will launch the "heretical" 996 water-cooled, the Boxster revolutionaries, and before changing productive mentality driven by Toyota changed forever small business. It was in 1995 when Porsche launched three sports in which track performance was all that mattered: The Porsche 911 Carrera RS, Carrera RSR and GT2.
Porsche 993 GT2 (1995): Original Sin
As I anticipated in the intro of the article, Porsche needed to approve a 911 to compete in the FIA GT2. His idea was to use as a base to Porsche Turbo 993, but the FIA regulations expressly prohibited the use of AWD. Porsche decided that the best approach to this category of high-flying was to create a Turbo propulsion, even more powerful and much lighter. This is how was born the first Porsche 911 GT2, the purest in concept and philosophy, the only street GT2 product of the need to standardize a race car. Of course, it is the most valuable.
The Porsche 993 GT2 was the fruit of a night of passion between a Carrera RS and Turbo No, it was more like registered a racing car, road legal. A level of motorization, the Porsche 993 GT2 employed mechanical air-cooled 3.6-liter six-cylinder 993 Turbo, but thanks to an increase in the blowing pressure of the turbochargers - 0.8 bar to 0.9 pubs - passing power of 408 hp turbo about 430 hp mareantes. The truly impressive Porsche 993 GT2 was the "wrapper" that this engine was responsible for encouraging: a wrapper ultralight and radical in the full sense of the word.
To get started, crystals were finer, doors and aluminum hood were now and instead of leather sports seats, he had a pair of baquets composite. From outside leagues he saw it was a special car: its wheel arches - fiberglass - extra wide were bolted to the body - before it became fashionable trainers - and on the rear hood is installed a huge spoiler and two air intakes ram-air type, air that fed the hungry boxer engine. The front bumper was redesigned so that the oil cooler could get more air flow.
In its huge wheel arches, Porsche installed huge 18-inch wheels with tires 285 mm section of the rear axle. Aesthetics and total absence of comfort equipment - power windows or air conditioning were optional - sought to separate the average customer of Porsche customer truly "burned". Client should be able to tame It is demanding a truly dynamic machine, with a performance of órdago: Thanks to its empty weight of 1,295 kg was only able to make the 0 to 100 km / h in 4.4 seconds, with a top speed of 295 km / h.
Which at the time they could try talking about an unusual ferocity of the absolute necessity of good hands to take quick - to take the limit it had to be a good professional pilot. Lost third wheel, understeering so stubborn if the curve is not properly faced and oversteering violently if "plumped" throttle full support. It was a car radical, without assistance of any kind. The car suddenly a dangerous reputation earned, and someone coined the phrase "Widowmaker -" widow maker "to refer to the Porsche 911 most powerful street.
The clients They could charge your 911 GT2 Club Sport package with, including anti-roll bars, baquets FIA homologated, a gutted interior insulation and both fins and bumpers constructed of carbon fiber. A race-client street, literally. The Porsche 911 GT2 competition swept mid-90s, but the competition had been the batteries, and for 1998, Porsche needed to approve an evolution of the 993 GT2. For this, the GT2 street raised its power to 450 hp, and he received a rear carbon fiber hood. He was baptized unceremoniously as Porsche 911 GT2 Evo.
Porsche manufactured only 57 units Porsche 993 GT2 Street - of which only 7 units carried the Club Sport package - and 21 units of the 993 GT2 Evo. However, 110 units were manufactured competition. Today it is one of the 911 most valuable ever created, and recently auctioned units over 2 million euros prices. When a 993 GT2 changes hands, it's news. It is without doubt one of the most special history 911, and although the GT2 have remained very rapid and radical, none would be as special as the last of the aircooled.
Porsche 996 GT2 (2002): the first liquid-cooled GT2
After years of absence, the Porsche 911 GT2 dealers again, this time based on a completely new architecture, the Porsche 996 with the water-cooled engine. Unlike its predecessor, It was not created because it was necessary to homologate a race car. Porsche refocused its client runs in the novel GT3, leaving vacant FIA GT2 category. Still, the Porsche 911 GT2 had inherited his father's temperamental character, oriented to customers who wanted to take your car to the limit: without electronic aids of any kind - or traction control or stability - without filters.
Again, and that philosophy itself has remained unchanged, it was a Porsche 996 Turbo raised to its highest expression. Like its predecessor, leaving four-wheel drive Turbo, and eliminated the option of automatic transmission, allowing only a manual gearbox six relations. The engine twin-turbo 3.6, the Turbo delivering no less than 420 hp, was "massaged" to the 462 hp, thanks to new turbochargers larger. However, it had a power to weight ratio worse than the 993 GT2, to be somewhat heavier: 1,420 kilos marked on the scale, compared with 1,540 kg of Turbo.
A novelty in the Porsche 911 GT2 was the standard features of carbonocerámicos brakes. Brake proving the intentions of this Porsche 911 GT2, even faster than its predecessor: it was the 0 to 100 km / h in just 4.1 seconds and had a top speed of 315 km / h. Again, the important thing at this GT2 were not pure performance, but their behavior. It was a car that gnawed again, and is said to Walter Röhrl himself up to him instilled a deep respect. Marking oversteer character, "devouring space on the road" according to American publication Motor Trend.
In the absence of electronic controls, Porsche adjusted suspension GT2 so that should occur some understeer cornering. The problem was that this understeer gave rise to a treacherous and very fast oversteer, which again earned the car a wild and unpredictable. "Widowmaker" was still a good nickname for this 911 spartan and uncomfortable, as irreverent as passionate. Many owners came to use different geometries for adjustable suspension, softening its unpredictability ... but maybe Porsche wanted to keep the popular ideology the "dark" side of the 911 GT2.
As a "grand finale" for the Porsche 996, launched in 2004 a revised version of the 911 GT2. Thanks to improved engine control unit, boosted power to the propeller 483 CV. The 0 to 100 km / h was reduced to 4.0 seconds, increasing 4 km / h the tip speed, as usual, courtesy of the rear axle and 18-inch wheels, shod with 315 mm section. In total about 2000 units Porsche 966 GT2 were produced, being about 40% to the US market. There was never Porsche 996 GT2 racing, at least created by Porsche.
Porsche 997 GT2 (2007) and GT2 RS (2010): the GT2 breaks the barrier of 600 hp
Porsche launched in 2007, three years after the premiere of the Porsche 997, a new GT2. The philosophy was similar to that of his predecessor again was a car based on the Porsche 997 Turbo without wheel drive and only equipped with a manual gearbox. The recipe also had other known methods such as a set-point for harder chassis and suspension and brakes carbonocerámicos elements enormous dimensions. It was a car whose engine is derived directly from bóxer 3.6L twin-turbo 996 Turbo. The engine that even today is based on the Porsche 991 Turbo was introduced in the 997 facelift in 2008.
One of the details that make this water-cooled engine - and then getting on in years - in a special mechanical muscle is that their turbos are variable geometry, eliminating almost entirely the classic lag of the supercharged engines of high specific power. While the 997 Turbo developing 480 hp with a few tweaks in the electronic control unit, a new intake and exhaust signed by Akrapovic titanium, Porsche 997 GT2 developed the 530 hp. Although the Porsche Carrera GT was the Porsche history over time, the 911 GT2 had the honor of being the most powerful Porsche 911 history.
The weight of the car remained at about very reasonable 1,440 kilos, a weight virtually identical to its predecessor. The engineers who developed the Porsche 997 GT2 had previously been employed in the program motorsport brand, and were pleased to install a new bumper with radiators and intercoolers which could breathe better. The rear spoiler is fixed, and the rear tires - mounted on alloy wheels 20 "- 325 mm section are necessary when the car is capable of reaching 329 km / h. Of course the carbonocerámicos brakes are standard.
Although the Porsche 997 GT2 was exceptionally fast and aggressive - 3.9 seconds in the 0 to 100 km / h - Porsche was aware that more than 500 hp without electronic aids could be more than challenging. So 997 GT2 endowed the PSM system, an advanced traction control and stability. He was a fully disconnectable system for the more adventurous owners. The Porsche 911 GT2 was a wild car without controls, sharp as a scalpel, blunt as a bazooka and treacherous in bad hands. But tied up in short by electronics, even a novice could drive it without any problems.
But Porsche still had a bullet in the chamber, and it was called "727 Project", whose final result was the impressive Porsche 997 GT2 RS 2010. The Andreas own Preuninger, head of brand development, has acknowledged on more than one occasion that the 911 final began as an internal project unknown by the board, and "727" referred to the time Nürburgring Nissan GT-R, 7 minutes and 27 seconds. The Porsche 997 GT2 RS come to roll in Nordschleife in 7 minutes and 18 seconds, until a certain Nissan GT-R NISMO ruined the party. But Porsche had already sent his message.
The GT2 RS had many changes over conventional GT2, if you can call it that. Although Porsche had released new 3.8-liter boxer and direct injection into the 997.2, the GT2 RS veteran remained faithful to 3.6 liters. Engine and other improvements had received new pistons, a new exhaust system, intake and improvements in turbochargers capable of blowing a greater pressure: the result was 620 hp - the most powerful Porsche history - and 700 Nm of maximum torque, thanks to which the car was capable of annihilating the 100 km / h in just 3.5 seconds.
Further, He had thinned whopping 70 kilograms, thanks to plastic parts reinforced with carbon fiber (CFRP) as hood, front lip or fixed rear spoiler, and also eliminating any interior equipment that was not strictly necessary. Infotainment had no equipment, the rear seats had been replaced by a roll cage and air conditioning was optional. Porsche kept even door handles, they were replaced by two strips of cloth. Only 1,242 units were manufactured 997 GT2 and 500 units of exclusive and radical GT2 RS, already a modern classic.
