Based on the already primal 997.2 GT3, the RS gets another 15 hp from the 3.8-liter flat-six for a total of 450, or more than 118 hp per liter. A racing machine tamed for street use, the GT3 RS is hardly just about horsepower. It gets a wider track, it weighs less, and it produces more downforce than the GT3. The only available transmission is a six-speed manual gearbox (with the ratios even shorter than the GT3). A racing machine tamed for street use, the GT3 RS also gets a wider track, it weighs less, and it produces more downforce than the GT3.
The 911 SC effectively replaced the 911 S and was one of Porsche's first models that was meant for the international market. It was sold as a cheaper alternative to the 911 Turbo. The SC used an unblown version the 930 Turbo unit that offered 180 to 200 bhp depending on model year. Options included the rear whale tail, front chin spoiler, Bilstein dampers, 16 inch wheels with Pirelli P7 tires and sports seats. Sometimes dealers lumped these options together to create their own sport package. It was available as a Coupe and Targa from 1978 - 1983, while the Cabriolet version was only available in 1983.
2019 911 speedster
Make no mistake that the Speedster is an absolutely fitting conclusion to the 991-generation. The Porsche 911 Speedster is an ingenious amalgamation of the latest technologies on offer, and the more simple ingredients that have been a principle of driving enjoyment since the invention of automobiles. A 502-horsepower engine, without turbochargers. A modern transmission, with just one clutch. A state-of-the-art suspension and chassis, with an unsullied purity. The list goes on. Perhaps the only drawback is that the Speedster’s rarity and price.
With all-wheel drive and all the GTS goodies, the Carrera 4 GTS sits in a very practical place in the Porsche 911 lineup. The 4 GTS is a Carrera 4S with all the items Porsche thinks you should have at a price that is less than choosing them yourself. Standard equipment on the GTS that is normally optional on the Carrera S includes the Sport Chrono Package, Sport Exhaust, bi-xenon lights with PDLS (Porsche Dynamic Lighting System) and PASM (Porsche Active Suspension Management). Inside, four-way adjustable sport seats are standard.
Most importantly, the refreshed Carrera 4 and 4S lose the old multi-plate, viscous all-wheel-drive system in favor of the electronically controlled system from the 911 Turbo. The old system could send between 5 and 40 percent of engine torque to the front wheels once it had detected wheelspin. The new electronic system can anticipate traction losses and shift up to 100 percent of engine torque fore or aft. Porsche says the new AWD system reacts faster to traction changes, and doesn’t make the Carrera 4 significantly heavier.
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 Porsche 911E continued as the midrange 911 for the 1970 and 1971 model years, fitting between the contemporaneous 2.2L 911T and the 2.2L 911S. It produced 155 bhp and featured all the upgrades that came with C-Series production including longer wheelbase, Fuchs alloy wheels. Both the E and S model 911 had an aluminium engine-lid and aluminium bumpers. The 911 E 2.2 was once again available as either a Coupe or Targa body. For model year 1972, the 2.2L 911E was replaced by the 2.4L 911E.
The 991.2 Targa did get some mild design changes, but they are all inline with the rest of the 991.2 changes. Despite the mild styling revisions, it’s a dramatically different car in terms of its engine. The iconic and highly regarded naturally aspirated 3.4-litre flat-six engine has been ousted for a more environmentally friendly twin-turbocharged 3.0-litre. It keeps its all-wheel drive system and is still an all-weather 911. A sports car with all-wheel drive is the first choice for more than one in three Porsche 911 buyers. It is sporty and comfortable, the turbo engines more powerful and consume less, with the improved all-wheel drive.
The 991.2 generation Carrera range update was a big one. The base coupe looks about the same, but under the hood Porsche did something crazy. Gone is the 3.4 liter naturally aspirated flat 6, replaced by a 3.0 turbocharged flat six. The good news is that the new engine is pumps out 370 hp and 331 ft lbs of torque, a big leap over the previous generation (output is up over the previous car by 20 horsepower and 44 lb-ft of torque). Inside, the updated 911 hasn’t changed dramatically, and although Porsche’s new PCM infotainment system is faster and more intuitive to use.
Designed as a grand tourer, the Porsche Carrera 4 Cabriolet was the base all-wheel-drive version for the open-top 911 range in 2001. It offered enough comfort to be used as a daily driver, on all weather. The 996 Porsche was facelifted in 2002. Along with the coupe versions, the convertibles were reshaped also. There was not a big difference on the outside. It was the same sports-car and open-top grand tourer. The Carrera 4 Cabriolet, continued on through 2004, receiving the same updates as the Carrera, including the 3.6-liter engine.
The 993 Turbo S, available between 1997 and 1998, bumped the power from the standard 993 Turbo up to 450hp (430 for the United States market) with larger turbochargers and a modified engine management system. The Turbo S was fitted with more luxury trim bits on the interior – with more leather and carbon fiber than on the standard Turbo. A larger rear wing was installed as well. Only 345 were built. Its direct successor was the 996 Turbo S for model year 2005.
