The 997.2 Turbo was introduced for the 2010 model year and received a new 3.8 litre engine capable of 493 horsepower, a significant evolution as compared to the 473hp in the 997.1 Turbo. The 997.2 Turbo was available in both manual and automatic transmissions, but the automatic evolved from the Tiptronic used in its predecessor, to a sportier dual-clutch PDK. Approximately 3,300 coupes were produced and 1,800 cabrios, far less than its predecessor. An epic all-around GT with more performance than you could ever need.
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.
The Cabriolet version of the new Porsche 911 Carrera 4 GTS is just as potent as its coupe sibling. It combines a 408 hp 3.8-litre flat six engine with intelligent all-wheel drive that delivers a further exhilarating dimension to the dynamics of the iconic rear-engined sports car. The 911 was first offered with four-wheel drive in 1989 and the drivetrain has been a popular option ever since. Now, the 911 Carrera 4 GTS broadens customer choice in 2011, building on the success of the two-wheel drive Carrera GTS that went on sale in December last year. Carrera 4 GTS power unit is the 3.8-litre flat six with power kit.
Porsche’s 911 GT2 RS is a brute, a lightweight, twin-turbocharged, 620-hp bout of madness that stemmed from Stuttgart’s quest to see how high up the sports-car ladder the 911 could punch. It is the most serious roadgoing Porsche ever. The engine is a port-injected, 3.6-liter flat-six from the Le Mans–winning GT1 race car of the late ’90s, with a pair of variable-geometry turbochargers huffing a maximum of 23.2 psi of boost into the combustion chambers. The result is 620 hp at 6500 rpm and 516 lb-ft of torque at 2250. It gets a six-speed manual gearbox and rear-drive only. Yikes.
It's not often Porsche creates an all-new model in their 911 lineup. But the 997 Carrera GTS is just that. It's faster, more powerful and better looking than any other model in the Carrera family. However it's still a little less hardcore than the 911 GT3, and a lot cheaper than the 911 Turbo. The Porsche 911 Carrera GTS features a 3.8 litre flat-six engine which is tuned to develop 408 horsepower, that's 23 hp more than the Carrera S manages. Think of it as the perfectly optioned Carrera S for less money.
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. 
The 911 Carrera Cabriolet is a true Porsche, from top to bottom. Like the rest of the range, the base Cabriolet got a mild refresh in terms of design that made it more modern and a little more crisp. The engine was upgraded, now with direct direction. The direct-injection 3.6-liter engine also got new air filters, a more free-flowing exhaust system, and reduced engine friction, making it more powerful than before. It has peak power of 339 bhp @ 6500 rpm and torque of 287 ft lbs @ 4400 rpm. The Carrera equipped with PDK covers 0-60 mph in 4.5 seconds and runs to a top speed of 179 mph.
The Porsche 997 GT3 Cup was a series of race cars created by Porsche to enter the Fédération Internationale de l’Automobile (FIA) Group GT3 racing class. Replacing the 996 GT3 Cup, the 997 Cup's 3.6 litre engine is rated at 294 kW (400 PS; 394 hp) and was mated to a six-speed sequential transmission. In 2009, the GT3 Cup received several 997.2 updates including a new 3.8 litre engine with an output of 331 kW (450 PS; 444 hp).
