The 997 911 GT3 RS is an even lighter and more purist version of the 911 than the regular GT3. 20 kilograms lighter than the GT3 and equipped with a close-ratio six speed manual the GT3 RS gets to 60 mph 1/10th of a second faster than the GT3. The 911 GT3 RS is 44mm wider at the rear than the GT3. The wider track helps improve directional stability when cornering. Weight savings can be found throughout the car. The Clubsport version there is a bolted roll cage, a six-point harness for the driver and a built in fire extinguisher. 
While the 997 Carrera 4S coupe sold a healthy 15,056 units between 2006 and 2008, the equally exciting Carrera 4S Cabriolet sold 12,587 units, making it a pretty popular 997 model. The reason is pretty simple. It had a gorgeous wide-body stance, all-wheel drive traction and that potent 3.8 L Flat 6 that was good for 350 bhp and 295 ft lbs of torque. The first convertible 911 that was as good a performer as it coupe siblings with the added benefit of open top driving in the summer with the comfort of being a great daily driver all year round. 
Along with its sibling Carrera 4, the 2005 Carrera 4S offered an all-wheel-drive system for the Porsche 911, but unlike the 4, the 4S gets the Carrera S' more powerful engine and it turns out that makes a big difference. The Carrera 4S was the more powerful and more dynamic version of the 997 Carrera 4 and an overall great sports car, especially for those in colder climates who need the safety of all-wheel traction. All rounder that fits nicely in the 911 lineup as perhaps the most practical.
The Carrera 4 Cabriolet was released with the rest of the 4 and 4S models as 2006 model year cars. With a sure-footed, four-wheel drive powertrain as well as that "wide-body" stance, and with tops that open or close at the touch of a button, the Carrera 4 Cabriolet really started to make the case it could do it all. The wide look gave the 4 a widened track, larger wheels and tires and four-wheel-drive powertrain that gives more dynamic stability, especially in inclement weather conditions. Developed at the same time as the coupe.
The 997 Carrera 4 was the all-wheel-drive version of the standard 997 Carrera and it arrived as a 2006 model year car (along with the 4S models). The 997.1 Carrera 4 had a3.6 L Watercooled Flat 6 (M96/05) engine that was good for 321 bhp @ 6800 rpm and 273 ft lbs @ 4250 rpm. It had a sub 5 second 0 - 60 mph hour time and a top speed of 174 mph. The transmission (six-speed manual or five-speed Tiptronic) feeds a forward propshaft that mates to a viscous coupling unit with a front differential.
The Carrera S convertible was introduced to the market at the same time with the Carrera Cabriolet, a few months after their coupe-versions were unveiled. The convertible version for the Carrera S got reinforcements needed for the cabriolet built while the engineering was going on for the coupe, ensuring that the drop-top version was just as strong and performance-focused. It got the same engine as the Carrera S and made a case for itself as the best 911 of the range at the time.
The 997 Carrera S was the first step up in performance over the base 997 Carrera. Available over two distinct generations, the 997.1 Carrera S used a 3.8-liter engine producing 355hp – the available X51 Powerkit bumped that number to 376hp. From 2009 onwards, the 997.2 Carrera S offered 380hp from 3.8 liters. Besides a more powerful engine, it also comes standard with 19 inch wheels, larger brakes, and a lowered suspension with PASM.
Just a few months after the introduction of the 2004 911 (997 series), the convertible version was released. The release of the 997 911 Carrera Cabriolet marked the first time since 1977 that Porsche has given the convertible 911s the same engines as their Coupe siblings. The base 997 Carrera Cabriolet gets the 3.6-liter flat six-cylinder engine with 321 bhp and 273 ft lbs of torque. The convertible version for both Carrera and Carrera S was developed at the same time with the coupe.

Porsche 9R3 “LMP 2000”
The Porsche LMP2000 (also known as the Porsche 9R3) is a Le Mans Prototype racing car that was developed between 1998 and 2000, but never raced. One car was built, and it was designed around a modified version of Porsche's 3.5-litre V10 engine that was originally designed for Formula 1 in 1992. The project was canceled before the car was built, leading to various rumors about the reason for its demise.
For the 2000 Paris Motor Show, Porsche prepared a concept supercar that eventually turned into a limited production car. The concept's basic shape and specification were close the production version, which included a low-mounted V10 engine that was sourced from their scrapped Le Mans prototype program in 1999. Two functioning concepts were produced for both the European and North American show circuits.
