Porsche 997 (2004-2012)

The Porsche 997 (Nine-Nine-Seven) is the internal designation for the Porsche 911 model manufactured and sold by German manufacturer Porsche between 2004 (as Model Year 2005) and 2012. Production of the Carrera and Carrera Scoupés began in early 2004, all-wheel drive Carrera 4 and Carrera 4S versions began shipping in November 2005, Turbo and GT3 derivatives went on sale in late 2006 and the 911 GT2 in 2007. In addition to the coupe and cabriolet versions,Targa versions of the Carrera 4 and Carrera 4S were also available, which carry on with the “glass canopy” roof design used on all Targa 911s since the Type 993 Generation 911.

During 2009 Porsche made comprehensive changes to the 997 lineup which included small styling changes, increases in engine displacement across the board, the addition of direct injection and the introduction of the company’s new “PDK” dual clutch transmission. As a result, the updated 997 models were faster, lighter and more fuel efficient than the outgoing versions and have somewhat better handling. In the case of the 997 Turbo, a comprehensively re-tuned all wheel drive system with an optional “torque vectoring” system was also a part of the upgrades package; in an October 2009 preliminary review, Car and Driver magazine estimated that when equipped with the PDK transmission, the updated Turbo should be capable of going from 0-60 mph in three seconds.

The 997 is the most commercially successful 911 of all time, having sold 100,000 units between its introduction in 2005 and July 2007. It has also received mostly positive reviews from the worldwide motoring press; even British motoring journalist Jeremy Clarkson, a known detractor of Porsche vehicles, noted that the 997 will “make love to your fingertips and stir your soul.”

The rear bodywork is a total of 88 mm (3.5 in) wider than its predecessor. However, the most notable aesthetic difference between the 997 and the 996 is the return to circular headlights like those of pre-996 Carreras, with separate indicator units. The interior has been almost entirely re-invented and all the controls are new; however, it is more reminiscent of classic 911 interiors than of the outgoing 996. The body in general remains low profile with a drag coefficient of 0.29 for the Carrera and .30 for the Carrera S. 

The base Carrera has essentially the same 3,596 cc (3.596 L; 219.4 cu in) flat-6 (Boxer) engine from Type 996 Carrera. The Carrera S uses a new 3,824 cc (3.824 L; 233.4 cu in) flat-6 engine. The X51 Powerkit is available for S, 4S, Targa models, which increases engine power.

According to testing carried out by several American automotive publications, the Turbo model can accelerate from 0 to 100 km/h (62 mph) in about 3.4 seconds with a Dual Clutch (PDK) and 3.5 seconds with the manual transmission. The Carrera S model is capable of going 0 to 60 mph (97 km/h) in 4.7 seconds, and carries a top speed of 300 km/h (190 mph), while the base Carrera model has 0 to 60 mph (97 km/h) acceleration in 4.8 seconds, with a top speed of 180 mph (290 km/h). Note, however, that these figures are conservative Porsche figures.

The viscous clutch all wheel drive system (997.1) sends between 5% and 40% of engine torque to the front wheels as needed.

First generation (2004-2009)

Cabriolet

For the first time, development of the cabriolet version of the 997 led the design and engineering effort at Porsche with the coupe following. Porsche applied the logic that if you started with the more difficult cabriolet challenges (for chassis stiffness) the coupe version would simply be that much more rigid. Despite additional weight, the cabriolet versions attain nearly the same performance figures as their coupe counterparts. Even the rear tail comes up slightly higher on the cabriolets to compensate for differences in drag over the canvas top vs. the smoother coupe shape.

911 Club Coupe (2005)

It is a limited (50 units) version of 2006MY Carrera S coupé with X51 Powerkit commemorating the 50th anniversary of the Porsche Club of America (PCA).[2][3]

The vehicle includes Azurro California-colored body (from Porsche 356), a vehicle identification number (VIN) which ends with the production number and special commemorative badging and door sills which adorn the interior, Sport Chrono Package Plus system, optional Porsche Ceramic Composite Brakes.

The car #1 was transferred to the Porsche Museum in Stuttgart, Germany and one PCA member won the car #50 in a sweepstakes drawing. The remaining 48 units were sold to randomly chosen U.S. and Canadian PCA members. After 2005-08-15, unsold units were made available to the general public.

The vehicle was unveiled in PCA’s 50th Annual Porsche Parade in Hershey, Pa.

The vehicle has MSRP of $99,911 US and $145,911 CDN.

Targa

The Targa 4 and Targa 4S versions, like the Porsche 911 Targa of the 993 and 996 generations, are equipped with a glass roof and hatch. At any speed, the roof can be opened where it drops down an inch and slides a metre back underneath the hatch. As the roof weighs an additional 60 kg (132 lb) the suspension has been modified from Carrera models. When the glass roof is retracted, a small glass deflector above the windshield is raised to aid in aerodynamic stability.

Unlike previous versions of the Porsche 911 Targa, the Porsche 997 Targa 4 and Targa 4S have an all-wheel-drive drivetrain, hence the “4” in the name. The naming is to fit in with the naming trend of other Porsche models, namely the Carrera 4 and Carrera 4S, whose “4” in the names are also due to their all-wheel drive systems. Targa 4 models are slightly slower than the hard top Carrera models because of the heavier roof and all-wheel-drive drivetrain.

GT3

Porsche 997 GT3 RSR

The 997 GT3 model also debuted in Geneva in 2006. Like previous GT3 models, it is a way for Porsche to homologate aerodynamic features for racing, as well as a starting model for customer racing. The 997 GT3 was priced at US$106,000. The engine has the same displacement as the Turbo, but without turbocharger and uses a new variable intake system. The engine is rated at 415 PS (305 kW; 409 hp) and 405 N·m (299 lb·ft).[5] It has an 8400 rpm redline which is the same as the 612 bhp (456 kW; 620 PS) Carrera GT’s. The 3.6L dry-sump engine does not seem to share the rear main seal (RMS) problems of the earliest 3.6L/3.8L semi-dry-sump engines.

The GT3 body includes a special front bumper which increases cooling for the front-mounted radiators as well as a split spoiler at the rear. The GT3 also includes a special rear bumper and center tailpipes which draw heat away from the engine. It is lowered and rides on 30-series 305mm (12 in) tires on 19in (483mm) wheels. The car weighs 3075 lb (1395 kg).

The 997 GT3 is more driver-friendly than its predecessor, with “comfort” seats and the Porsche Communication Management system installed.

The special RS model[6] came without most of these luxuries out to focus more on track-oriented driving (although the car is still road-legal). The package also included a full rollcage and carbon fiber seats to add to that race-car-for-the-road feel. The RS version was released in Europe in October 2006; the North American release was in March 2007.[7] A racing version of the GT3 RS debuted in 2007, and it was called the 997 GT3 RSR.

The ratios on the six-speed transmission are more aggressive, allowing the GT3 to hit 60 mph (97 km/h) in 4.1 seconds, while the RS accomplishes the same in 4 flat. It will continue to 100 mph (160 km/h) in 9.2 seconds and has an ungoverned top speed of 310 km/h (190 mph).

Turbo

The 997 Turbo debuted in February 2006 at the Geneva Motor Show. It featured a new front bumper with LED turn signal strips in the air intakes; the fog lamps were moved to the corners of the bumpers. Large air intakes fore and aft of the rear wheels provided other obvious visual cues of the Turbo model. Also featured was a retractable rear wing, as used on the 996 Turbo.

The engine was based on the rugged and reliable 964/GT1 design rated 480 PS (350 kW; 470 hp) and 620 N·m (460 lb·ft). The turbochargers are fitted with a two-stage resonance intake system.

The engine uses two BorgWarner VTG turbos, a first for Porsche. The Variable Turbine Geometry incorporates guide vanes on the turbine wheel that change their angle of attack with exhaust speed, reducing boost lag at low speeds while opening up to prevent excessive back pressure at high RPMs. Such variable geometry turbines were previously only available on diesel engines.

2009 Porsche 997 Turbo in Carrera White

The optional Sport Chrono package allows the 911 Turbo to overboost for ten seconds, increasing peak torque over a narrow RPM range.

According to official Porsche figures, the 997 Turbo accelerates to 100 km/h (62 mph) in 3.9 seconds with the manual transmission, and 3.7 seconds with the Tiptronic S transmission. It also recorded a 60 mph (97 km/h) time of 3.2 seconds when tested by Motor Trend, eclipsing all of its major competitors and even Porsche’s own Carrera GT supercar. The 997 Turbo has an official top speed of 318 km/h (198 mph), though Jeremy Clarkson achieved an indicated speed of 322 km/h (200 mph) during his 2008 video special, Clarkson: Thriller.

Turbo Cabriolet

Porsche AG announced on May 7, 2007 that the 911 Turbo Cabriolet would go on sale in September 2007. The Porsche 997 Turbo Cabriolet became one of the fastest convertible sports cars in production. It is capable of similar top speeds and acceleration to the standard Porsche 997 Turbo Coupe, a notable feat due to the typical problems associated with convertible variants of hardtop coupés, such as the poor aerodynamics of a soft top, a lack of torsional rigidity, and the consequential weight increase from structural members.

GT2

2007 Porsche 997 GT2

This is the most powerful and fastest road-going 911 GT2 ever to be sold to the public.[8] The Porsche 996 911 GT2 was superseded by the 997-generation GT2, on sale since November 2007.

The 997 GT2 has a twin turbocharged 3.6 litre 6-cylinder engine based on 997 Turbo but Porsche achieved power increase through completely newly designed expansion intake manifold in which the distributor pipe is longer than in Turbo and the intake manifolds are shorter, a full titanium silencer is used also in GT2, even though the Porsche 911 (997) Carrera S variant has a slightly larger engine at 3.8 litres. Despite the power hike, Porsche claims fuel consumption at full throttle is improved by 15 percent compared with the Turbo. The GT2 accelerates in 3.6 seconds to 60 mph (97 km/h) and in 7.4 seconds to 100 mph (160 km/h) and has top speed of 329 km/h (204 mph). This makes it the first Porsche 911 GT2 to exceed the 200 mph (320 km/h) top speed after the 1998 Porsche 911 GT1 Race Version (which is not considered an actual Porsche 911 due to its mid-mounted engine and it only saw roads for homologation purposes). The Porsche 997 GT2 has a curb weight of 1,440 kg (3,200 lb). The only transmission choice is a 6-speed manual gearbox.

The GT2 is the first Porsche equipped with launch control.

Its appearance is slightly different from its sister-car, the Porsche 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 larger rear wing (with two small air scoops on either side), and it has a different rear bumper (now featuring titanium exhaust pipes).

Second generation (2009-2012)

The 997 was revised in 2008 for the 2009 model year. The updated Porsche 911 (called 997 Gen II internally at Porsche) included following changes:

Production began at late 2008. Pricing was increased from the 997, Gen I; the base Carrera model is set to start at US$ 76,300 for North American buyers.

Initially available models include coupe and cabriolet versions of Carrera, Carrera 4, Carrera S and Carrera 4S. The car was unveiled at the Paris Auto Show in September 2008.

On June 6, 2008, these changes to the Porsche 911 were revealed on the Porsche website. The Turbo will have to wait until the Frankfurt show in September, thereafter the Turbo-based GT2 will be updated.

Targa (2009-present)

The updated Targa 4 and Targa 4S models were announced on the 28th of July 2008. The new Targa 4S has a top track speed of 185 mph and goes 0 to 60 in 4.7 seconds, while the Targa 4 is slower and has less mpg.

Turbo/Turbo Cabriolet (2009-)

Red Porsche 997 Turbo Cabrio (2010).

The facelifted version of the 997 Turbo, was unveiled at the 2009 Frankfurt Motor Show. It received a completely new 6-cylinder, 3.8 liter boxer engine delivering 500 hp (370 kW) with revised Borg-Warner variable turbine geometry (VTG) turbos. The 911 Turbo is now only available with a manual gearbox or the optional 7-speed PDK dual-clutch gearbox, which replaces the Tiptronic. With PDK and the also optional sport-chrono package, which includes the availability of a electronically controlled launch-control and an overboost-function for temporary increasing the turbo-pressure, Porsche claims the 911 turbo will go from 0 to 100 km/h (62 mph) in 3.4 seconds and reach a top-speed of 194 mph (312 km/h). However, several tests done by Auto-Magazines and unpartial testers have revealed that the 0–100 km/h acceleration-time is generally as low as 2.9 seconds. The model can now also be ordered with PTV, Porsche Torque Vectoring, which will brake the inner wheel to provide turning-torque through a curve. The looks of the facelifted model was left mostly untouched from the original 997 turbo, but there are subtle changes to the rear lights, now being LED-type, among changes to the front lamps. The rear exhaust outputs are now also “fatter” and the standard 19-inch (480 mm) wheels now have a new design. Thanks to revised dynamics the facelifted 997 can handle 1.3 g forces on a skid-pad according to Porsche. Its believed that the updated 997 Turbo was benchmarked against the Nissan GT-R in response to 3rd party testing between the 997 Turbo and the GT-R.

Models equipped with PDK also include an optional 3-spoke steering wheel with gearshift paddles as an alternative to the standard steering wheel with shift buttons.

Other optional equipment include Porsche Torque Vectoring (PTV).

Production versions went on sale in Germany in November 2009. European models have MSRP of €122,400 for Coupé and €131,800 for the Cabriolet (before tax).

Turbo S (2010-2012)

This higher spec Limited Edition Turbo was released at the Geneva Motor Show in March 2010. Available only with a 7-speed PDK transmission, the Turbo S boosts power by 30 hp (22 kW) to a total of 530 hp (395 kW) and an impressive torque of 700 Nm.[17] European deliveries are scheduled for May 2010 while production Ending in Fall 2012. Porsche’s Fastest Released production vehicle to date. 0-to-60mph acceleration: 2.6 seconds. Maximum torque of 516 lb-ft in the 911 Turbo S models is available between 2,100 rpm and 4,250 rpm. The 911 Turbo S models, by contrast, are configured to operate with a higher boost pressure level, which means that their maximum torque of 516 lb-ft is available for an unlimited period.

GT3 (2010-)

Porsche 997 GT3 (2010)

The 2010 Porsche 911 GT3 was unveiled at the 2009 Geneva Motor Show,[14] available in Europe from May, in the US from October.[14] To make the GT3 safe for less experienced drivers, the stability control system is available[18] on the 2010 model year GT3 for the first time.[14] Changes to the exterior are only subtle still recognizable[14] bringing about aerodynamic improvements.[14] Total downforce has been doubled.[14] Power output rises from 415 to 435 PS with the new 3.8L engine.

GT3 RS (2010-)

Porsche 997 GT3 RS (2010)

It is a version of GT3 with more engine power, lower weight and shorter transmission ratios, as well as upgraded body and suspension components, designed for homologating the race version of the 911 GT3. Engine was rated 450 PS (330 kW; 440 hp) with 8500 rpm redline. The “RS” stands for the German “RennSport”, meaning “Racing Sport” in English.

The transmission has shorter ratios than found in the 911 GT3 for improved acceleration. Dynamic engine mounts are standard and serve to improve the car’s handling to an even higher level. Other features include PASM suspension, a titanium crankshaft, a wider front and rear track and corresponding bodywork.

Optional equipment include lithium-ion battery, which is 10 kg (22 lb) lighter than stock lead-acid battery. The vehicle was unveiled in 2009 Frankfurt Motor Show. US model was set to go on sale in early spring of 2010 with MSRP of $132,800US.

GT3 Cup (2009-)

It is a Porsche Carrera Cups race car based on 911 GT3 RS. It includes 44 mm (1.7 in) wider rear body, 15 mm (0.59 in) lower front spoiler lip, 1.70 m (67 in) rear wing (from 911 GT3 Cup S race car), LED taillights, racing exhaust system with a fully controlled catalytic converter, a modified special exhaust system offering more dynamic and muscular sound (from Porsche Mobil1 Supercup cars), Porsche Ceramic Composite Brakes. 9.5Jx18 front alloy wheels with 24/64-18 Michelin racing tyres and 12Jx18 alloy wheels with 27/68-18 tyres, additional Unibal joints on the track control arms and front and rear sword-shaped anti-roll bars with seven position settings each, additional vent in the upper part of the front lid, steering wheel mounted Info Display with 6 switches, Carrara White body. The vehicle was unveiled in 2009 Frankfurt Motor Show.

It is a limited (250 units- all sold) version of 911 Carrera S coupé, inspired by the 1973 Carrera RS 2.7. The engine is rated 408 PS (300 kW; 402 hp) via newly developed resonance intake manifold with 6 vacuum-controlled switching flaps. It includes 6-speed manual transmission, double-dome roof, 44 mm (1.7 in) wider rear body, SportDesign front apron with spoiler lip and the rear spoiler fixed in position (from 1973 Carrera RS 2.7), PCCB Porsche Ceramic Composite Brakes, 20 mm (0.8 in) lower PASM sports suspension, mechanical rear axle differential, 19-inch wheels with black rim spokes, Porsche Exclusive woven leather seats and door panels, dashboard with Espresso Nature natural leather upholstery, Sport Classic Grey body colour.

The vehicle was unveiled in 2009 Frankfurt Auto Show.[21]

Production vehicles went on sale in January 2010. European model had base MSRP of €169,300 (before tax).[22]

Top Gear featured it in season 15 episode 02 on July 4, 2010.

911 Carrera GTS (2011-)

911 Carrera GTS (2010)

For 2011, Porsche is making a new, mid-level 911 coming in above the Carrera and below the GT3. Ranging from $103,100 to $112,900 USD, the Carrera GTS is available as both a coupe and cabriolet, the car gets a wider body and track - the only Carrera with a wide track that is also rear wheel drive. The car also gets an upgraded 3.8-liter engine producing an impressive 408 horsepower (304 kW).[23] An AWD version, the Carrera 4 GTS was revealed in May, 2011. In addition to the AWD system, the Carrera 4 GTS can be identified by a distinct reflective stripe between the tail lights.

911 Speedster (2011-)

911 Speedster (2010)

For 2011, Porsche will make a new 911 Speedster. They will only make 356; the production number coming from the iconic car of the 1950s. It will be the third 911 Speedster made, the other 2 being from the 930 and 964 generations. The Speedster is powered by the same engine in the Carrera GTS, and produces 408 horsepower (304 kW). It can go from 0-60 in 4.2 seconds, and will eventually reach a top speed of around 190 mph (310 km/h). Only 2 colors will be offered, Pure Blue (which was developed especially for the Speedster) and Carrara White. (Paint To Sample versions were produced in very limited numbers).

The Speedster features a windscreen 70mm shorter than the standard 997 cabrio while maintaining the same rake angle.

GT3 RS 4.0 (2011-)

In April 2011, rumours of a 4.0 liter version of the 997 GT3 RS started appearing in various automotive publication, soon followed by supposed spy shots and rendered images. Eventually, Porsche revealed that they were making the 911 GT3 RS 4.0, the final evolution of the 997 featuring a 4.0 litre engine. The engine itself features the crankshaft from the RSR with increased stroke dimensions (from 76.4mm to 80.4mm). This has increased the power to 500 PS (368 kW; 493 hp) at 8250 rpm and 460 N·m (339 lbf·ft) of torque at 5750 rpm. Chassis development has been influenced by the GT2 RS and uses bits from other RS 911s. Front dive planes give additional downforce up front. The car weighs in at 1370 kg, giving it a power-to-weight ratio of 365 bhp per ton. Only 600 cars will be built.

Porsche 996 (1998-2005)

The Porsche 996 is the internal designation for the Porsche 911 model manufactured and sold between 1998 and 2005. It was replaced by the Type 997. Both body styles were produced by Porsche in 2005, based upon model type.

At its debut, the 996 featured the most significant changes to the Carrera model since its 1963 introduction; the most significant change with this new iteration is the water-cooled engine replacing the previously air-cooled engine. Progressively stringent noise regulations, environmental concerns, a higher expectation for refinement and a high-performance 4 valve per cylinder engine made the switch necessary. The 996 Carrera (non GT and Turbo models) engine is designed with what Porsche calls the “integrated dry sump oiling”. This “integrated dry sump” engine does not have an oil scavenge pump in the crankcase to pump the engine oil to a separate holding tank outside the crankcase as a true dry sump design would have. The only scavenge pumps in the 996 engine are in the camshaft boxes and the oil is pumped from there to the bottom of the crankcase as it would be in any “wet sump” engine. Other changes include a sleeker body with a more steeply raked windshield and a re-designed interior.

The Porsche 996 was an all new design made by Harm Lagaay; the first new 911 that didn’t carry over a significant component from a previous variant. All new body work, interior and drive-train including the first water-cooled engine in a 911. The Porsche 996 replaced the Porsche 993.

The first 996s were available as a coupe or cabriolet initially with rear wheel, or later, with four-wheel drive, and a 3.4 litre flat-6 normally aspirated engine producing 296 bhp (224 kW). These cars had the same headlights as the Porsche Boxster. Porsche Carrera owners complained loudly and long about the “lower priced car that looked just like theirs did “, hence the headlight change for the Carrera. The design for these headlamps could be traced all the way back to the Porsche Panamericana concept car.

In 2000, Porsche debuted the 996 Turbo, equipped with four-wheel-drive and a 3.6 litre, twin turbocharged and intercooled flat-six producing 420 bhp (309 kW), making the car capable of 0 to 60 mph in 4.2 seconds. An X50 option which included larger turbochargers and intercoolers along with revised engine control software became available from the factory in 2002, increasing power to 450 hp (336 kW). (Porsche produced a Turbo S in 2005, which also had the x50 option with 450 bhp, alongside the formerly optional Carbon fibre-reinforced Silicon Carbide (C/SiC)composite ceramic brakes (PCCB) as standard equipment.)

In 2001, horsepower on the base Carrera model was increased by 4 bhp to 300 bhp. In 2002, the standard models underwent minor re-styling, which included switching to the Turbo-style headlamps and to a new front fascia. These were sometimes known as the Mk2 generation of the 996, or the 996.2. In addition, engine capacity was also increased to 3.6 litres across the range, yielding gains of 15 horsepower for the naturally aspirated models. 2002 also marked the start of the production of the 996 based Targa, featuring a sliding glass “green house” roof system like its Type 993 predecessor. Also in 2002, the Carrera 4S model was first introduced. The C4S as it is commonly called, shares the widebody look of the Turbo as well as the brakes and suspension.

GT variants

996 GT3 (1999)
996 GT3 (2002)
996 GT3 RS (2002)

The 996 platform was used as the basis for two lightweight GT variants called GT2[1] and GT3. The GT3 was based on the standard 996 Carrera, but was stripped of a great deal of equipment for weight savings, featured stiffer, adjustable suspension and upgraded brakes, and used the bodyshell of the four-wheel-drive version, which incorporated additional front-end stiffening. It was produced in two versions. The first, commonly referred to as the Mk.I GT3, was released in 1999 in all markets, save North America. It featured a naturally aspirated version 3.6L flat six making 360 bhp (270 kW). This engine was shared with the 996 Turbo and was a derivative of the Le Mans winning engine developed for the 911 GT1. The Mk.II GT3 variant was based on the second generation of the 996, and featured updated aerodynamics, and a more powerful version of the 3.6L engine from the MK.I, now producing 380 bhp (280 kW). The Mk.II was the first GT3 marketed in the North America. In a 2004 testing of the Mk.II GT3, the car accelerated 0-60 mph in 4.0 seconds, and produced 1.03 g on the skidpad, the second highest number ever recorded by a street legal automobile.

Also its counterpart, the GT2, was RWD to save weight and to avoid power losses through the transmission.[2] (This is primarily due to the fact that it was built to compete in GT2 class racing, which mandated RWD). It received an added group of aerodynamic body parts, and a re-tuned version of the 996 Turbo’s 3.6 litre, twin turbocharged engine featuring larger turbochargers and intercoolers, revised intake and exhaust systems, and re-programmed engine control software. The result was 489 hp (365 kW) and 484 lb·ft (656 N·m) of torque respectively, enough to launch the car from 0 to 60 mph (97 km/h) in 3.9 seconds and to a top speed of 198 mph (319 km/h). Bigger wheels and tires along with lightweight ceramic brakes were standard.[2] The GT2’s fixed rear wing (made of CFRP for the post-2003 cars) appears to be a concession to racing rules that usually outlaw moving aerodynamic devices.[2] It had no rear seat and no air conditioning.[2] Both cars were available only with six-speed manualtransmissions.

The Turbo, GT2 and GT3 models use the Aluminum crankcase of the air-cooled 911 with its true dry sump oiling system. The six separate individual Nikasil lined cylinders in this engine are covered with two separately installed water jackets each covering a bank of 3 cylinders on each side of the engine, thus adding water cooling to a crankcase originally designed for air-cooled cylinders (the normal 996 Carrera engine has the cylinders and water jackets cast together with the crankcase). This engine is very similar to that of the Le Mans winning Dauer Porsche 962 and Porsche GT1 racing cars’ engines.

Naturally Aspirated Carrera Evolution

The 99 Model year featured a 3.4L engine producing 296 bhp. The 2000 and 2001 model years received a slight increase in horsepower to an even 300 bhp while retaining the same figures for torque produced. In addition, Porsche made many changes to the 3.4-liter unit over its production lifespan, so the last of the last of these 3.4L engines (made in 2001) have improved reliability.[3]

The 2002+ cars received a 3.6L engine which provided an extra 15 bhp (11 kW) of horse power (taking output to 315 bhp or 320 ps) and an additional 15 lb.ft of torque (increasing from 258 to 273). The inclusion of Variocam Plus (as opposed to Variocam on the earlier 996) improved power delivery through the rpm range. The headlights on the 996 Carrera also adopted the turbo headlights of the MK1 iteration. Seat belt pretensioners were also added and the Tiptronic in 2000 was modified to allow it to enter manual mode by clicking the steering wheel mounted buttons.

Updates also included an updated front bumper to decrease front end lift and the addition of a glove box. The “MK2” 996 gained 55 lbs. compared to the “MK1” in this facelift.

Special editions

Porsche offered a special edition of the 996 for the year 2000. The company introduced the car as “The 911 for the Millennium” and based it on the Carrera 4 coupe. Only 911 were made.

This special edition was finished in Violet Chromaflair paint with natural leather interior and dark burr maple trim. Available with a Tiptronic or six-speed manual gearbox, the car was well-equipped. A number plate on the center console and a unique “911” badge on the engine lid and lettering on the door sills make this special edition easy to identify.

Porsche celebrated the 911’s 40-year history in 2003, using the slogan, “40 Jahre 911/40 Fast Years”. The company also introduced the 996 “40th Anniversary Edition” for model year 2004. This model has the 996 Turbo’s front-end, and was available only in Carrera GT Silver exterior paint. Other unique features included: X51 power kit, turbo radiators, limited slip differential, sport suspension, polished 5-spoke alloys (unique to this model), GT3 side skirts, natural gray leather interior (with luggage set to match), sports seats (there was a power comfort seat option), polished exhaust tips, heated seats (option in Latin America), litronic bi-xenon headlights, special dynamic sealed panels, and a special “40 Jahre 911” logo on the back. The power was increased from 316 to 345 hp (257 kW). Only 1,963 units were made, to commemorate 1963—the year the 911 was introduced.
