In addition to the 911 Turbo, Dr. Ing. h.c. F. Porsche AG of Stuttgart, Germany, is presenting another new automobile at the Geneva Motor Show. The new 911 GT3 will be unveiled to the world public for the very first time on February 28, 2006. This two-seater sports coupe will go on sale across Europe in May 2006.
In the 911 model range, the abbreviation GT3 stands for pure, unadulterated driving pleasure. With its uncompromising dynamics, this model impresses not only in normal day-to-day driving but also on the racetrack. The 305-kW (415-bhp) 3.6-liter flat-twin engine produces a specific output of 84.7 Kilowatts (115.3 bhp) per liter of displacement. This performance places the new-generation GT3 in its displacement class at the pinnacle of road-legal production sports cars wîth naturally aspirated engines.
The six-cylinder engine reaches its nominal output at 7,600 rpm. At 8,400 rpm, the engine speed limit again lies 200 revolutions higher than for the previous model. This makes it a world leader in its engine-size class. In addition to this high engine speed concept, the optimized airflow rate considerably improves performance. This is made possible by the variable intake system wîth a throttle valve enlarged from 76 to 82 millimeters, the optimized cylinder heads and an exhaust system wîth low backpressure.
The driver has a revised six-speed transmission at his disposal. It impresses wîth its very short gearlever travel and, thanks to the lower ratios of gears 2 to 6, ideally complements the racy engine.
New for the GT3 is a change-up display, which lights up on the rev counter shortly before the relevant engine speed is reached. It provides an additional signal at the best time to change gear. The measured values prove just how well the engine and gearbox are harmonized: the GT3 accelerates from 0 to 100 km/h in 4.3 seconds, and reaches 160 km/h from a standing start in 8.7 seconds. Its top speed is 310 km/h.
The new 911 GT3 boasts an active chassis for the first time. Porsche Active Suspension Management (PASM) offers two sporty chassis in one: the basic configuration is largely similar to that of the previous model and is suitable for driving on alternating road surfaces. In sport mode, the system switches to harder damping, thereby enabling even better dynamism on the racetrack.
For the best-possible transmission of engine power to the road, the GT3 is equipped wîth a comprehensive traction package, which includes not only the standard-equipment 19-inch sports tires but also a mechanical limited slip differential. In addition, the new electronic Traction Control – adapted from the Carrera GT high-performance sports car – ensures safe traction under any driving conditions. It features traction-slip and drag-torque control functions, and can be switched off completely if required.
The basic Euro price for the 911 GT3 is 93,000 Euros. In Germany, it will be offered including sales tax and country-specific requirements for 108,083 Euros. In the ÚSA, the new GT3 will be available in dealerships from August 2006 for 106,000 Dollars (excluding tax).Source - Porsche AG

Porsche 911 997 GT3 Cup
Porsche Cars GB has re-affirmed its long-term commitment to British motorsport by unveiling the car that will be used in the Carrera Cup GB for at least the next three years.The all-new 911 GT3 Cup (Type 997) will be introduced in the 2006 Carrera Cup and continue for 2007 and 2008 in a new three-year programme. The existing model (Type 996) has been used in the Carrera Cup GB since the championship was introduced in 2003.
The new model was officially unveiled at a reception at Porsche Cars Reading on the evening of Saturday 30 April.
Since it first supported the British Touring Car Championship in 2003, the Porsche Carrera Cup GB has become firmly established as the fastest single marque racing series on the ÚK's premier national motorsport calendar. The combination of evocative sports coupe styling and characteristic rear-engine design makes the Porsche 911 a favourite for drivers seeking a precisely engineered, powerful race car, and one that is immediately recognisable by spectators and sponsors alike.
The next evolution of the Carrera Cup GB will build on this proven reputation and continue to offer competitors the same high level of support from Porsche Cars GB. An extensive prize fund, excellent technical support, race centre hospitality, championship management, TV coverage and media services will all continue to underpin the Porsche Carrera Cup GB.Source - Porsche
Unveiled to the world in 1999, the Porsche 911 GT3 was a high performance variant of the original water-cooled version of the Porsche 911, the 996. It continued the 25 year tradition of low-weight RS models that was ended with the 993 RS. The name GT3 was taken from the Fiat GT class that it had been designed for, and it didn't use the simple engine of the standard production versions of the 996, while also a naturally-aspirated variation of the turbocharged Porsche 962 and Porsche 911 GT1 race vehicles. Though it didn't fit into GT racing regulations like the 993 GT2, the turbo-charged Porsche 911 GT2 was added to the maker's lineup. Racing versions of the GT3 were awarded several major 24h races and completely dominated their class at Le Mans.
The Porsche 911 GTI won the 24 Hours of Le Mans in 1998 and Porsche chose not to enter the '99 Le Mans due to not having a factory vehicle that was good enough to defend the overall win against the competition by major automakers. This was also due to an internal agreement again on less expensive GT racing classes at the Grand-Am Rolex racing series, the 24 Hours of Le Mans, and started plans to update the new 996 generation of the 911. At the same time they produced a road-worthy variant, they developed a race car. In 1999 this car was introduced at the Geneva Motor Show before it went on sale.
The GT3 came with an engine unlike any other 996 models, even though it shared the same basic 3.6 liter displacement of the standard 996 ‘integrated dry-sump' flat-six engine. This engine is based completely on the original air-cooled 911's versatile, true dry-sump crankcase with an external oil tank. Originally the GT3's engine had 360 PS, in comparison to the 300 PS of the original 996.
Quite similar to the completely water-cooled 962 racing car's engine, the GT3 engine configuration was a so called 'split' crankcase uses separate water jackets added onto each side of the crankcase to cool banks of three cylinders with water pumped through a radiator, rather than a fan and finned cylinders. This engine is also based on this same crankcase. This engine is different though because the 962 utilized 6 individual cylinder heads while the GT1/GT3 used 2 cylinder heads, each covering a bank of 3 cylinders. One could think of the GT3 engine as a similar to a 959 engine, but with water-cooled cylinders.
The basic casting utilized for the crankcase of the GT3, up until 2004, was virtually the same as the air-cooled engine. The '964' casting number on the bottom of the crankcase and areas could clearly be seen and were normally machined in the air-cooled application that are not machined for use in the water-cooled application. Halfway through the 2004 year, a '996' casting number crankcase to eliminate these external air-cooled remnants, while internally it remained virtually the same.
Dating back to the Porsche 904/6 of the mid-1960's, the engine gives the GT3 a distinct racing heritage all the way up the racing vehicles of today.
The GT3 utilized a manual gearbox that was also of air-cooled 911 heritage, due to the 911 air-cooled crankcase that used the Porsche 356 engine to transmission mounting flange configuration. The gear ratios were interchangeable on the gearbox and it was much more durable which makes it more preferable for racing over the standard 996 type 911 gearbox. The most ‘powerful naturally aspirated six-cylinder engine' in any production vehicle, was the 3.8 liter flat-six engine in the 997 GT3 and GT3 RS, rated at 435 hp.
The 2004 Porsche 911 GT3 is considered to be the most powerful non-turbocharged production vehicle that had ever been offered in North America. Considered to be a true sports vehicle that allowed you to achieve lap times on the racetrack, no one really expected it to also be a street-legal and non-turbocharged road vehicle. President and chief executive officer of Porsche Cars North America, Peter Scwarzenbauer is quoted as 'This is the fastest normally aspirated Porsche road car' and 'the sports car for the purist, through and through'.
Though the GT3 didn't come with a back seat, and other commodities drivers really preferred, it continued to be a car than can be driven on a daily basis. The GT3 also maintains the same fuel consumption ratios as other 911 models, though it produced more horsepower and torque. The '04 Porsche 911 GT3 is rated at 380 hp at 7,400 rpm and 284 lb-ft of torque at 5,000 rpm. In first, second, third and fourth gears, the engine revs to 8,200 rpm right before its computerized rev limiter is activated.
The 04 Porsche 911 GT3 could achieve 0-60mph in just 4.3 seconds and could hit 100 mph in just 9.4 seconds. The brakes were also bigger on the GT3 than the 911 Turbo's. The GT3 is also equipped with 13.78-inch front brake discs and six-piston fixed calipers that increase the contact area between the discs and the pads. In a carry-over of a Porsche tradition, the six-piston brake calipers are adorned with a red paint. By 40% these calipers enlarge the contact area between the brake lining and the brake disc in comparison to the first generation GT3. The front discs are also nearly an inch larger than those found on the '03 911 turbo. Much like the Turbo's, the rear discs are 13.00 inches. Patented by Porsche, the cooling ducts were inner-vented and cross drilled, while the front discs are 1.34 inches thick. The sickle-shaped ducts act like a turbine inside the discs which made a significant contribution to cooling behavior.
The rotors at the rear measure 1.10 inches thick and are cross-drilled and inner-vented and feature four-piston calipers. Brake caliper pistons are separated by heat-insulating circonium ceramic inserts which reduced the transmission of temperatures from the brakes to the hydraulic fluid. The Porsche 911 GT3 came with enhanced aerodynamics, mainly due the streamlining of the vehicle's body that included a swept-back nose, a large rear spoiler, and sculpted side sills. All of these components together reduce lift forces on both rear and front axles. The improved aerodynamics along with the more powerful engine resulted in a top track speed of 190 mph. The aerodynamic nature also provides more flow that cooled the GT3's braking system. Directing air to the brake discs and calipers were spoilers that were integrated into the cars wheel wells.By Jessica Donaldson
