CLASSIC BEAUTY AND ALL-WHEEL TRACTION

ATLANTA – The 2003 Porsche 911 Carrera 4 Cabriolet combines the classic beauty

of the 911 convertible with the superior all-weather traction of all-wheel-drive and

the enhanced control of the Porsche Stability Management system (PSM).

“While the Carrera 4S gets the full Turbo-look, wide-body treatment, the C4

Cabriolet retains the elegant styling of the classic 911 Carrera,” says Frederick

J. Schwab, President and CEO of Porsche Cars North America.

The fully automatic power soft-top with glass rear window and integrated defroster

on the Cabriolet folds compactly into a compartment behind the rear seats. A

solid tonneau cover fits flush against the body with the roof lowered, preserving

the sleek, uncluttered appearance. A removable aluminum hardtop with a heated

rear window is included as standard equipment.

Based on the 911 Carrera Cabriolet, the 911 Carrera 4 Cabriolet differs most in

that its drivetrain powers all four wheels. It uses an all-wheel drive system based

on a viscous multi-plate clutch located directly behind the front differential.

Weighing only 120 pounds (54 kg), the all-wheel drive system in the 911 Carrera

4 Cabriolet qualifies as one of the lightest such systems in the industry.

The all-wheel drive system directs 5 to 40 percent of the torque to the front wheels,

depending on available traction and power applied. The viscous unit compensates

for differing wheel speeds during cornering. While the 911 Carrera 4 Cabriolet

exhibits superior traction on all road surfaces, Porsche did not intend the all-wheel

drive system as an all-weather traction assistant. The all-wheel drive system was

designed to handle the unexpected curves and bends in the roads as Porsche

racecars always have.

Porsche equips the 911 Carrera 4 Cabriolet with the advanced Porsche Stability

Management system (PSM) as standard equipment, and offers it as an option on

the 911 Carrera. Using data from several sensor inputs, PSM can detect a loss

of grip at the front or rear and reduce instability by applying braking to individual

wheels and, if necessary, altering engine power.

On slippery roads, PSM can help keep the 911 Carrera 4 Cabriolet going in the

direction the driver steers. The PSM system operates so quickly that most drivers

likely will not feel it make corrections. The driver can disengage PSM with a

dashboard switch. However, for safety, PSM will engage under braking and then

disengage when the driver lifts off the brake. While the system provides dynamic

handling aid, Porsche cautions drivers that PSM cannot counteract the laws

of physics.

Subtle exterior differences that distinguish the 911 Carrera 4 Cabriolet from its

rear-wheel drive sibling include plainly visible titanium-color brake calipers and a

titanium-color “Carrera 4” logotype on the rear engine hood.

In 2002, the Carrera Coupe, Cabriolet and Carrera 4 Cabriolet gained a more

powerful engine, strengthened body structure and updated styling cues. The

only significant change for 2003 is the installation of a standard digital AM/FM

radio featuring an in-dash CD player.

The design changes were much more than cosmetic. The new front air intakes

increased airflow to the radiators by 15 percent. Reshaping the radii of the front

wheel arches and adding small, flexible spoilers ahead of the front wheels

reduced lift at the front by 25 percent and at the rear by 40 percent. In addition,

new air intake ducts enhanced front brake cooling, and a new under-floor duct

enhanced transmission cooling by 20 percent.

The new headlight design designed from the 911 Turbo improved lighting

performance.

Porsche also enhanced comfort and convenience. A standard onboard computer

conveys information on an LCD display in the lower third of the tachometer. In

addition to information about fuel consumption and driving range, the computer

can display engine oil level, outside temperature and 35 different warning

messages in plain text.

The remote entry system controls seat memory function when the optional power

seats are ordered. The remote determines which of the four car keys is in use

and transmits the information for driver’s seat position and exterior mirrors to the

memory control unit. Apart from the function provided by the four programmable

keys, the driver can select two other seat positions via buttons to the left of the seat.

Optional parking aid with sensors integrated into the bumper covers can help

prevent parking maneuver fender-benders by sounding an audible alert as the car

gets closer to an obstacle.

“boxer” engine produces 315 horsepower (SAE) at 6,800 rpm and 273 lb.-ft. of

torque at 4,250 rpm, with at least 236 lb.-ft. from 2,500-7,000 rpm, and at least

265 lb.-ft between 3,800 and 6,000.

VarioCam Plus not only adjusts camshaft position to provide continuously

adjustable valve timing, but incorporates two camshaft profiles and two sets of

tappets to vary both valve lift and duration, as well. The new system helps

“fatten” and smooth out the torque curve, while helping to reduce emissions.

The dual-stage resonance air intake system helps boost power and torque at

midrange engine speeds.

Patented LOKASIL high-silicon cylinder liners help reduce friction and wear to

such a level that Porsche can recommend a 15,000-mile (24,000 km) oil change

interval and a 30,000-mile (48,000 km) oil filter change interval.

Porsche offers a choice of two transmissions: a precisely shifting standard six-speed

The Tiptronic S transmission is adopted from the 911 Turbo, which can handle

greater torque output. The lock-up torque converter and shifting programs have

been specially tailored to the naturally aspirated engine.

In automatic mode, Tiptronic S uses infinitely variable shift points to respond to the

driving circumstances and the driving style. During leisurely driving, Tiptronic S

will upshift early to provide a quiet ride and the best fuel efficiency. With quicker

gas pedal action, the transmission responds by raising shift points to hold each

gear longer for crisp response and power. The Tiptronic S transmission draws

from among 250 different shift maps to provide optimal performance at all times.

Even while in automatic mode, the computer-controlled Tiptronic S responds like

a driver working a manual transmission, downshifting or holding lower gears when

cornering and driving on hills. Tiptronic S allows the driver to select manual mode

by pressing an up- or downshift button, even with the shift lever in the “D” position.

four-wheel independent suspension features a Porsche-optimized MacPherson-strut

design in front and a multilink setup in the rear, both with aluminum suspension

components to reduce unsprung weight. Front and rear stabilizer bars and

gas-charged shock absorbers provide flatter cornering. Standard power rack-and

pinion steering yields a quick 2.98 turns lock-to-lock and a tight 34.8-ft.

(10.6-meter) turning circle.

A “staggered” wheel/tire array (wider wheels and wider, lower-profile tires on the

rear) contributes to neutral handling. The standard aluminum alloy wheels

measure 17 x 7 inches in front and mount 205/50 ZR17 tires; the 17 x 9-inch

rear wheels mount 255/40 ZR17 tires. The optional 18-inch wheel/tire package

further enhances the already sharp handling. The wheels measure 18 x 8 inches

in front and 18 x 10 inches in back; tires are 225/40 ZR18 in front and 285/30

ZR18 in.

The 911 Carrera models stop with four-wheel vented disc brakes with ABS 5.3

anti-lock control. Derived from the Porsche GT1 racecar, one-piece brake

calipers reduce heat and unsprung weight. The front discs measure 12.5 inches

in diameter and 1.1-inch thick (318 mm x 28 mm). The rear discs measure nearly

as large at 11.8 inches in diameter and 0.95-inch thick (299 mm x 24 mm). The

cross-drilled rotors dissipate heat to maintain braking performance and brake

feel even under hard usage. (Porsche requires brakes to provide 25 consecutive

full-force stops without fade.)

With the high performance potential of the 911 Carrera 4 Cabriolet comes a high

level of occupant protection. A patented crumple zone body structure protects

a reinforced passenger compartment. Supplementing the three-point inertia-reel

seatbelts are seatbelt pretensioners and load limiters. All new Porsche models

include dual front airbags plus the Porsche Side Impact Protection System that

includes boron-steel door reinforcement beams, energy-absorbing door panels,

and door-mounted side airbags. The 30-liter capacity sidebags provide additional

protection for the chest, head, and pelvis.

In the 911 convertible models, the boron-steel reinforced A-pillars and windshield

header combine with automatic-deploying supplemental safety hoops to reduce

the risk of injury in the event of a rollover accident.

At a customer’s request, a U.S. Porsche dealer can install a system that

deactivates the passenger airbags when a U.S. Porsche-approved child seat is

used. The system features a cross brace with belt lock in front of the passenger

seat. Buckling the special child seat into this brace deactivates the airbags. To

player, navigation system, and trip computer, all linked through Media-Oriented

Systems Transport (MOST) digital databus. The MOST system incorporates light-wave

conductors that exchange data between the individual components without loss

of quality and at ultra-high speeds.

PCM includes a 5.8-inch color screen with its 16:9 aspect ratio and 12-position

keyboard for easily and efficiently entering radio frequencies. The system assures

excellent audio quality.

The navigation module provides such features as road junction zoom-in, dynamic

navigation to avoid congestion, map scrolling so you can see beyond your current

position, tour planning with the ability to memorize as many as eight destinations in a

row and a CD-ROM system that can be used for the navigation system or for music.

Reflecting its evolution into a grand touring sports car, the 911 Carrera models

come with many standard luxury features:

• Digital AM/FM cassette stereo system with in-dash CD

  player

• Anti-theft system with engine immobilizer and alarm

• Automatic climate control with dust/pollen and

  activated charcoal odor filters

• Heated power sideview mirrors

• Remote locking system

All Porsche models feature light-emitting diode (LED) interior orientation lights.

One LED provides gentle illumination of the cockpit and center console. An LED

on the driver’s side door handle illuminates the ignition lock and light switch, and

an LED illuminates each door latch.
