2006 Porsche 911 GT3 Cup
Driver: Bryce Miller. Sponsors: Marquis Jet, Paul Miller Porsche.
Team: Farnbacher Loles Racing
Series: IMSA GT3 Cup Challenge
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 with 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 with a throttle valve enlarged from 76 to 82 millimeters, the optimized cylinder heads and an exhaust system with low backpressure.
The driver has a revised six-speed transmission at his disposal. It impresses with 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 with 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
Grand-Am Series Classes & Vehicles
The starting field of the Grand-Am Series is formed of two vehicle classes - the so-called Daytona Prototypes and the GT vehicles. The technical regulations for the two classes are designed to produce exciting races at comparatively low costs by restricting the development scope as well as by using standard components and racecar standards very close to those of production vehicles.
The Grand-Am GTs
are 390 - 450 hp racecars that are derived from standard production GT sportscars or coupés. The different vehicle and engine concepts are balanced out in the regulations on the basis of vehicle weight, tyre sizes or speed limit. The GT class is therefore currently similar to the European FIA GT3 category.
Various Porsche teams take to the start line in a 911 GT3 Cup 'Grand-Am', lining up against cars based on the Camaro GT.R, Pontiac GTO/GXP, Ford Mustang, Mazda RX-8, BMW M3 or Ferrari 430.
The Daytona Prototypes
are thoroughbred mid-engine racecars. The vehicle chassis are supplied by specialist manufacturers licensed by the Grand-Am such as Riley, Crawford, Dallara or Lola. All chassis designers have to stick to prescribed vehicle dimensions and standard components such as the rear wing, with the teams only allowed to make minimal changes.
To keep the field level, large car manufacturers are not allowed to enter their own teams - their involvement is restricted to providing the engines. The racing engine does approx. 510 hp in the setting for Daytona Prototypes. The minimum weight of the racing car is 1,021 kilograms.Source - Porsche
