Porsche 911

The Porsche 911 (pronounced as Nine Eleven, German: Neunelfer) is a luxury 2-door sports coupe made by Porsche AG of Stuttgart, Germany. It has a distinctive design, rear engined and with independent rear suspension, an evolution of the swing axle on the Porsche 356. The engine was also air-cooled until the introduction of the Type 996 in 1998. Since its introduction in autumn 1963[1], it has undergone continuous development[2]. The basic concept has remained little changed throughout its evolution.[2]

Throughout its lifetime, the 911 has been modified by private teams and by the factory itself for racing, rallying and other forms of automotive competition. It is among the most successful competition cars ever. In the mid 1970s, normally aspirated 911 Carrera RSRs won major world championship sports car races such as Targa Florio, Daytona, Sebring and Nürburgring, even against prototypes. The 911-derived 935 turbo also won the coveted 24 Hours of Le Mans in 1979.

In the 1999 international poll for the award of Car of the Century, the 911 came fifth.[cn] It is the one of two in the top five that had remained continuously in production (the original Beetle remained in production until 2003), and was until 1998 the most successful surviving application of the air- (now water-) cooled opposed rear engine layout pioneered by its original ancestor, the Volkswagen Beetle. It is one of the oldest sports coupe nameplates still in production.

The 911 can trace its roots back to sketches drawn by Ferdinand "Butzi" Porsche in 1959. The Porsche 911 classic was developed as a much more powerful, larger, more comfortable replacement for the Porsche 356, the company's first model. The new car made its public debut at the 1963 Frankfurt Motor Show (German: Internationale Automobil-Ausstellung). The car presented at the auto show had a non-operational mockup of the 901 engine, receiving a working one in February 1964.

997 GT3

The 911 GT3, announced on February 24, 2006 accelerates 0–100 km/h in 4.1 seconds and reach a top speed of 310 km/h (193 mph), almost as quick as the Turbo. Porsche's factory reports can be conservative though; Excellence magazine tested the 997 GT3 and recorded 0–100 km/h in 3.9 seconds and a top speed of 312 km/h (194 mph). The 997 GT3 was released in the summer of 2006. It was at that time crowned "the best handling car in America" by Motor Trend.
[edit] 997 GT3 RS

The 911 GT3 RS was announced in early 2006 as a homologation version of the GT3 RSR racing car for competition events like Sebring and the 24 Hours of Le Mans.

The drivetrain of the RS is based on the 911 GT3, except for the addition of a lightweight flywheel and closer gear ratios for further improved response under acceleration. Unlike the GT3, the RS is built on the body and chasis of the 911 Carrera 4 and Turbo, and accordingly has a wider rear track for better cornering characteristics on the track.

Visually, the RS is distinguished by its unique color scheme - bright orange or green with black accents, which traces its roots to the iconic Carrera RS of 1973. The plastic rear deck lid is topped by a wide carbon-fiber rear wing. The front airdam has also been fitted with an aero splitter to improve front downforce and provide even more cooling air through the radiator.

The European version of the RS is also fitted with lightweight plexiglass rear windows and a factory-installed roll cage.

Production of the first generation 997 GT3 RS ended in 2009. An estimated 413 units were delivered to the US and the worldwide production run is estimated to be under 2,000 vehicles.[19]

In August 2009, Porsche announced the second generation of the 997 GT3 RS with an enlarged 3.8-liter engine producing 450 bhp (336 kW), a modified suspension, dynamic engine mounts, new titanium sport exhaust, and modified lightweight bodywork.[20]
[edit] 997 GT2

The Type 996 911 GT2 was superseded by the Type 997 GT2 in 2007. On July 16, 2007, Porsche sent out the first official press release concerning the 997 GT2. The GT2 was officially launched during the 62nd Frankfurt Motor Show, which is held biannually in Frankfurt, Germany. The new 911 GT2 arrived at dealerships on November 2007.

The 997 GT2 has a twin turbocharged 3.6 litre 6-cylinder engine, which generates 523 hp (390 kW) at 6500 rpm. The GT2 accelerates in 3.6 seconds to 60 miles per hour (97 km/h) and in 7.4 seconds to 100 mph (161 km/h) and has a maximum top speed of 204 mph (328 km/h). This makes it the first street-legal 911 to exceed 200 mph (322 km/h), with the exception of the 1998 911 GT1 road car (which is sometimes not considered a true 911 due to its mid-mounted engine). The Porsche 997 GT2 also has a curb weight of 3,175 lb (1,440 kg), 505 lb·ft (685 N·m) of torque from 2200 to 4500 rpm, and a 6-speed manual gearbox.

The American auto publication Motor Trend tested a 2008 Porsche 911 GT2 0-60 mph at 3.4 seconds, and 11.4 seconds at 127.9 mph (205.8 km/h) for the quarter mile. The GT2 also recorded a braking distance from 60 mph (97 km/h) to 0 of 98 feet (30 m) and recorded 1.10g lateral grip. The GT2 made an appearance on Top Gear, where it had a lap time of 1:19.5, faster than a Carrera GT by .3 of a second.

A few official pictures of the Porsche 997 GT2 have also been released to publics, and more have been released through the GT2's official minisite.[24] Its appearance slightly differs from its sister-car, the 911 (997) Turbo, in a few ways. It does not have fog lights in the front bumper, it has a revised front lip, it has a different rear wing (with two small air scoops on either side), and it has a different rear bumper (now featuring titanium exhaust pipes).

The 997 GT2 is also different from the 997 Turbo in that the GT2 is rear-wheel-drive rather than all-wheel-drive.
