2003 Porsche 911 Carrera
Porsche 911 Carreraf
Whether it’s the engineers who worked on the enhancements for the 2003 Porsche Boxster, those gruelling at exercise development the Porsche Cayenne suv (SUV), or those from over-the-counter sports car manufacturers, their benchmark for manipulation and operation is the Porsche 9-11 Carrera.
“The Porsche 9-11 is the humanity’s touchstone for sports cars,” says Frederick J. Schwab, Chairperson and CEO of Porsche Cars N America. “This is what a sports car should be. It’s fun. It’s potent. It’s exact. Whether you’re cabaret racing on the weekend or determination new curves to search on your day-after-day transpose, it can pee-pee every crusade an exciting receive.”
For 2003, the Porsche 9-11 Carrera Coupe and Cab are powered by Porsche’s 3.6-liter, horizontally opposed six-cylinder “pugilist” locomotive, which produces 315 hp (SAE) and 273 lb.-ft. of torsion. A rightful sports car, the 9-11 Coupe weighs less than 3,000 pounds and sprints from a standing beginning to 62 mph (100 km/h) in 5.0 seconds on its way to a top test-track velocity of 177 mph (285 km/h).
And, Porsche owners acknowledge that such amphetamine is just parting of the equivalence. The Porsche 9-11 Coupe and Cab accomplish optimal equaliser betwixt execution and manipulation, betwixt exciting kinetics and sumptuosity comforts, and ‘tween alive and inactive refuge technologies.
2003 Porsche 911 Carrera
New digital radio and in-dash CD player for 2003
The Porsche 9-11 Carrera Coupe and Cab underwent blanket enhancements for 2002, including a bigger and more potent locomotive and a reinforced structure with updated styling. Those changes extend complete for 2003, with the Coupe and Cab besides weaponed with a received digital AM/FM tuner and in-dash CD histrion.
Such updates and upgrades get been a coherent contribution of the 9-11’s almost 40-year story, yet passim its life-time the car has maintained a canonic – and now classical — visibility intentional some its rear-engine architecture.
VarioCam enhances engine’s power curve
With 315 h.p. (SAE), the 9-11 Coupe and Cab are the almost sinewy ordinarily aspirated 9-11 models e’er offered in N America.
Although based on the water-cooled Porsche 9-11 Carrera locomotive introduced in example twelvemonth 1999, the range of this “pugilist” expanded done the instalment of new crankshaft, pistons and connecting rods. Its outturn was promote enhanced by the up-to-the-minute looping of Porsche’s patented VarioCam Addition valve timing and facelift organization. Patented LOKASIL high-silicon cylinder liners assistance concentrate clash and wearable to such a story that Porsche can urge a 15,000-mile (24,000 km) oil vary separation and a 30,000-mile (48,000 km) oil dribble modify separation.
The former VarioCam arrangement ill-used varying cam aligning to depart valve convergence to supercharge torsion done the midrange without sacrificing high-rpm hp. Now, VarioCam Asset not but adjusts camshaft situation to offer endlessly adjustable valve timing, but incorporates two camshaft profiles and two sets of tappets to depart both valve heave and length, too. The new arrangement helps “plump” and smooth the torsion bend, patch portion to slim emissions.
The dual-stage ringing air inlet organisation – optimized for the bigger supplanting locomotive – helps supercharge ability and torsion at midrange locomotive speeds. The 2003 9-11 Carrera locomotive produces 273 lb.-ft. of visor torsion at 4,250 rpm, with 214 lb.-ft. as low as 2,000 rpm and leastways 236 lb.-ft. from 2,500-7,000 rpm, including a midrange torsion “tableland” of leastwise 265 lb.-ft. from 3,800-6,000 rpm.
The modish ME 7.8 locomotive direction controls outright reckon the accurate provide of fire requisite from the cooler. Erst, fire not requisite by the injectors – but het by the locomotive – went backrest to the cooler. This arrangement reduces hydrocarbon emissions caused by het fire. Consecutive multi-port fire injectant features offprint fire mix ascendence for apiece cylinder swear, and a coil-on-plug ignition provides warm reply and true performance. The ME 7.8 locomotive mastery faculty incorporates the E-Gas electronic gas. In position of a traditional accelerator telegraph frame-up, E-Gas electronically transmits cycle place to the locomotive command whole. New mufflers with less backpressure than ahead breathe a more sinewy audio done freshly intentional tailpipes.
The Porsche 9-11 Carrera Coupe can quicken from residual to 62 mph (0-100 km/h) in fair 5.0 seconds, the Cab in 5.2 seconds when furnished with the touchstone six-speed manual contagion. A five-speed Tiptronic S robotic transmitting cadaver an alternative for all Porsche 9-11 Carrera models.
Choice of manual or Tiptronic S transmissions
Porsche offers a option of two transmissions on the Porsche 9-11 Carrera models: a exactly shift banner six-speed manual and the optional Tiptronic S five-speed machinelike transmittal. Porsche increased the torsion content of the manual transmittance for the more brawny 2002 models by victimization stronger metal blade on key components. In gain, the outturn calamus runs in tercet bearings alternatively of two, and the derivative uses stronger cant gears. As ahead, a dual-mass flywheel ensures low palpitation, and a hydraulic clutches provides uniform functioning.
The Porsche 9-11 Carrera models espouse the Tiptronic S contagion from the 911 Turbo, which can deal greater torsion turnout. The lock-up torsion convertor and shift programs sustain been peculiarly bespoke to the course aspirated locomotive.
In reflexive style, Tiptronic S uses immeasurably varying shimmy points to react to drive destiny and drive flair. During easy impulsive, Tiptronic S leave upshift betimes to allow a placidity rag and the topper fire efficiency. With faster gas fulfill, the transmittance responds by upbringing switching points to clench apiece gearing yearner for toast reaction and powerfulness. The Tiptronic S infection draws from among 250 dissimilar switch maps to render optimum execution at all multiplication.
Level in reflex mood, the computer-controlled Tiptronic S responds alike a driver workings a manual transmittal, downshifting or belongings glower gears when cornering and impulsive on hills. Tiptronic S allows the driver to choice manual way by pressure an up- or downshift release, eventide with the switch jimmy in the “D” place.
Aluminum suspension components
The four-wheeled fencesitter reprieve nether the 9-11 Coupe and Cab features a Porsche-optimized MacPherson-strut figure before and a multilink frame-up in the back, both with al abeyance components to dilute unsprung burthen. Breast and ass stabiliser bars and gas-charged cushion absorbers render blandish cornering. Received mightiness rack-and shackle steerage yields a nimble 2.98 turns lock-to-lock and a stringent 34.8-ft. (10.6-meter) turn round.
A “staggered” cycle/outwear align (wider wheels and wider, lower-profile tires on the backside) contributes to achromatic treatment in the Porsche 9-11 Carrera models. Carrera II 17-inch wheels use a slim rundle designing to slim unsprung burthen by more fin pounds per cycle ended the old excogitation.
The banner aluminium debase wheels step 17 x 7 inches ahead and setting 205/50 ZR17 tires; the 17 x 9-inch back wheels backing 255/40 ZR17 tires. The optional 18-inch bicycle/weary bundle farther enhances the already acute treatment. The wheels quantity 18 x 8 inches ahead and 18 x 10 inches in rear; tires are 225/40 ZR18 ahead and 285/30 ZR18 in cover.
The Porsche 9-11 Carrera models occlusion with four-wheeled vented platter brakes with ABS 5.3 anti-lock ascendancy. Derived from the Porsche GT1 racecar, one-piece bracken calipers slenderize oestrus and unsprung weightiness. The movement discs bill 12.5 inches in diam and 1.1-inch fatheaded (318 mm x 28 mm). The ass discs quantity almost as enceinte at 11.8 inches in diam and 0.95-inch fatheaded (299 mm x 24 mm). The cross-drilled rotors shoot heating to observe braking operation and bracken look level nether laborious utilisation. (Porsche requires brakes to render 25 sequent full-force chicago without disappearance.)
Porsche Stability Management
Optional on the 9-11 Coupe and Cab is the ripe Porsche Constancy Direction scheme (PSM). Victimisation information from various detector inputs, PSM can observe a deprivation of clutches at the movement or bum and slenderize imbalance by applying braking to soul wheels and, if requirement, neutering locomotive index. On slippy roadstead, PSM can assistant support the 9-11 sledding in the focussing the driver steers. The PSM scheme operates so apace that nearly drivers probably volition not smell it piddle corrections. The driver can withdraw PSM with a splashboard shift. Nevertheless, for prophylactic, PSM leave engross nether braking so withdraw when the driver lifts off the bracken.
Piece the arrangement provides active treatment aid, Porsche cautions drivers that PSM cannot sabotage the laws of physics.
Safe by design
With the heights execution possible of the Porsche 9-11 Carrera models comes a gamy floor of occupier shelter. A patented crinkle partition structure protects a strengthened rider compartment. Supplementing the three-point inertia-reel seatbelts, the Porsche 9-11 Carrera models birth seatbelt pretensioners and payload limiters. All new Porsche models admit twofold battlefront airbags addition the Porsche Incline Gremlin Auspices Organisation that includes boron-steel threshold reinforcer beams, endoergic doorway panels, and door-mounted slope airbags. The 30-liter content sidebags ply extra auspices for the pectus, caput, and hip.
Cabriolet has reinforced structure
The Porsche 911 Carrera Cabriolet has boron-steel built A-pillars and windscreen coping and an automatic-deploying auxiliary rollover construction to slim the hazard of harm in the outcome of a rollover fortuity.
The full robotic ability soft-top on the Cab folds succinctly into a compartment ass the bottom seating. A unanimous tonneau masking fits charge against the eubstance with the ceiling lowered, preserving the aerodynamic, unlittered appearing.
The Cab top features a crank back windowpane with entire deicer.
A obliterable al hardtop with a het backside windowpane is included as criterion equipment.
Available U.S. child seat
At a client’s asking, a U.S. Porsche trader can establish a arrangement that deactivates the rider airbags when a U.S. Porsche-approved fry backside is put-upon. The scheme features a crossing pair with whang lock strawman of the rider ass. Buckling the limited nestling backside into this bracing deactivates the airbags. To instal the scheme, the bargainer besides moldiness reprogram the airbag mastery faculty.
Styled for form and function
The styling update in 2002 included a reinforced structure that enhanced manipulation, drive and prophylactic. The styling changes adoptive the headlamp invention of the 9-11 Turbo, addition a fresh molded front, widened bottom stern panels and redesigned quarter pipes. But such innovation changes are more decorative. The breast air intakes increased airflow to the radiators by 15 percentage. Reshaping the radii of the forepart pedal arches and the add-on of belittled, pliable spoilers forward of the presence wheels rock-bottom elevator at the presence by 25 pct and at the ass by 40 pct. New air aspiration ducts enhanced forepart bracken chilling, and a new under-floor channel enhanced transmittance chilling by 20 percentage.
Tied the headlamp excogitation improved light execution. The Bi-Xenon gas-discharge headlights that are criterion on the 9-11 Turbo are an choice for the Porsche 9-11 Carrera models. These sparkle units use high-intensity gas sack bulbs for both the low and eminent beams.
Optional parking aid with sensors incorporated into the bumper covers can service forbid parking channelise fender-benders by looking an hearable awake as the car gets finisher to an obstruction.
Communicating at the speed of light
Porsche’s new Communicating Direction arrangement (PCM) comprises tuners, CD musician, piloting scheme, and stumble figurer, all coupled done Media-Oriented Systems Transferral (About) digital databus. The Well-nigh arrangement incorporates light-wave conductors that substitution information betwixt the somebody components without expiration of timbre and at ultra-high speeds.
PCM includes a 5.8-inch gloss filmdom with its 16:9 scene proportion and 12-position keyboard for well and expeditiously entrance radiocommunication frequencies. The organisation assures first-class sound timber.
The seafaring faculty provides such features as route colligation zoom-in, active pilotage to forefend over-crowding, map scrolling so you can see bey your flow office, circuit preparation with the power to memorise as many as eighter destinations in a row and a CD-ROM arrangement that can be secondhand for the sailing organization or for euphony.
Comfort and convenience
Porsche too enhanced the ease and gizmo of the Porsche 9-11 Carrera models. The board includes a measure onboard calculator that conveys entropy on an LCD presentation in the frown 3rd of the tach. In summation to info almost fire use and drive orbit, the estimator can exhibit locomotive oil layer, external temperature and 35 unlike monitory messages in quetch textbook.
A three-spoke sports wheel is stock. The distant launching organisation controls behind storage use when the optional might seating are logical. The outback determines which of the 4 car keys is engaged and transmits the entropy for driver’s arse place and outside mirrors to the retention restraint whole. Isolated from the use provided by the quadruplet programmable keys, the driver can quality two otc bum positions via buttons to the left-hand of the backside.
The 9-11 has a lockable glovebox and a cupholder incorporated into the centerfield.
Optional Bose audio system
Porsche offers a high-end digital sound scheme from abode and self-propelled sound producer Bose. Apiece organisation has been custom-engineered for that detail exemplar. The Bose self-propelling medicine systems trust balanced stereophonic, a bird’s-eye vocalise stagecoach, abstruse basso and shine frequence reaction to grow pictorial medicine replica eventide in the thought-provoking environs of a car inner. Digital amplifiers supply strip, uncoloured voice at any hearing storey. The 12 forward-looking loudspeakers (11 for Cab models) and a subwoofer coalesce seamlessly into cabin reduce, upbringing and turnout the audio phase and ensuring balanced stereophonic.
Banner sumptuosity features admit:
All Porsche models have led (LED) midland preference lights. One LED provides assuage light of the cockpit and centerfield cabinet. An LED on the driver’s english threshold handgrip illuminates the lock and twinkle substitution, and an LED illuminates apiece latch. The optional Porsche Communicating Direction organisation integrates controls and displays for World Location Orbiter (GPS) pilotage, onboard figurer, and clime restraint. An LCD coloration blind displays all functions.
