2003 PORSCHE® BOXSTER®
ATLANTA – With the Boxster, Porsche brought mid-engine performance and concept car styling to the street. For 2003, the roadster has undergone discreet refinements that enhance both its performance and its styling. But in typical Porsche fashion, even the styling changes contribute to improved performance. The styling changes include a new roof with a glass window and electric defroster, new lower front and rear fascia and a new rear spoiler. These changes are much more than mere cosmetics. Each of the changes improves aerodynamic efficiency by enhancing airflow to the engine, around the exhaust system or over the redesigned spoiler.
Also new for 2003 are engine enhancements that increase the output of the Boxster’s 2.7-liter horizontally opposed six-cylinder “boxer” engine to 225 horsepower (SAE). The car now accelerates from a standing start to 100 km/h (62 mph) in only 6.4 seconds, an improvement of two-tenths of a second compared to the 2002 model.
But the engine modifications improve more than just the 2.7-liter’s power output. They also enhance the engine’s all-around efficiency so that the “boxer” returns better fuel economy, than the 2002 model. The Boxster’s performance can be improved even more through the availability of new lightweight wheels.
Other changes for 2003 include a new pop-out cupholder, a lighted and locking glove compartment, more uniform dash-mounted switchgear, new interior trim colors and remote unlocking front and rear trunks.
Also new are Porsche Communication Management systems (PCM) that incorporates tuners, CD player, navigation system and trip computer, all connected to each other through the new Media-Oriented Systems Transport (MOST) digital databus.
“True to its Porsche heritage, when it came time for the Boxster to undergo subtle styling changes, the underlying reason was to enhance performance,” says Frederick J. Schwab, president and CEO of Porsche Cars North America Inc. “Whether it’s the more powerful engine or the way adding a glass window improves airflow to the rear spoiler, the car’s style and substance work very well together.”
The Boxster’s new top has a steeper angle along its rear section and provides a contour that’s very similar to that of the Boxster’s optional aluminum hardtop. The new shape is provided by an additional, fourth roof bracket above the new glass window. The glass window comes with electric heating to provide improved visibility in cold and damp weather. Even with its fourth roof bracket and new glass window, the Boxster’s top still features electric kinematic power and opens or closes in 12 seconds.
The new roof is lined and has optimized seals to minimize noise inside the car when the top is up. The roof is designed so that the rigid, magnesium frame that forms the front edge of the roof provides protection for the glass window when the roof folds away above the engine compartment.
The top’s new shape enhances airflow to the Boxster’s redesigned rear spoiler. The spoiler fits smoothly into the shape of the body when retracted, and then lifts automatically into position at 75 miles per hour (120 km/h) to keep the car stable by reducing rear axle lift at Interstate and Autobahn speeds. The spoiler then retracts at 50 mph (80 km/h). Adjacent to the rear spoiler are smoked lenses for the rear directional signals.
Beneath the rear spoiler is a redesigned oval tail pipe flanked by a new and more aerodynamically efficient lower rear facia. The rear fascia has two wide openings that allow better cooling airflow around the Boxster’s exhaust system. Airflow also improves at the front of the 2003 Boxster and to the car’s 2.7-liter engine.
Beneath the car’s front bumper are two new cooling air intakes. The new intakes have greater curvature than the former air intakes, providing a “ram” effect to enhance the flow of air for cooling and aerodynamic efficiency.
The redesigned front fascia also includes a more sharply contoured lower front “lip.” A change that owners won’t see but will appreciate is a new composite component between the body cross-support and the front body panels. This “cushion” provides additional protection and reduces the cost of repairs should the car bump into a curb while parking.
Airflow to the Boxster’s 2.7-liter engine is enhanced to the engine through revised and now body-colored side vents located just in front of the rear wheel wells. The vent on the driver’s side takes in air for the fuel/air combustion mixture while that on the passenger’s side provides air to cool the engine compartment.
This enhanced airflow combines with new VarioCam® technology, new Motronic ME 7.8 engine management controls, a “returnless” fuel supply system and improved oil pump to make the Boxster’s 2.7-liter engine more powerful and efficient. For 2003, the “boxer” pounds out 225 horsepower (SAE) at 6,300 rpm, compared to 217 for the 2002 model. The engine’s torque figure remains 192 pound-feet at 4,750 rpm.
The engine isn’t only more powerful; it’s also cleaner and more fuel efficient. With its manual transmission, the Boxster achieves an EPA city rating of 20 mpg, and 29 on the highway and 11.7 l/100km and 7.4 for Canada. The figures are 18 and 26, 13.3 and 8.3 for Canada respectively, with the Tiptronic transmission.
Formerly, the camshaft could be adjusted up to a range of 25 degrees, but this newest VarioCam technology allows infinite adjustment of the crankshaft angle by up to 40 degrees. This reduces charge cycle losses, improving power, mileage and keeping exhaust emissions to a minimum. Porsche was the first manufacturer to introduce this integrated design, which was launched in the 911® Carrera®.
With VarioCam, intake camshaft timing is fully variable through a wing-cell adjuster fit directly on the camshaft drive sprocket. Oil pressure is used to turn the position of the inner wing-adjuster wheel versus the outer sprocket by up to 40 degrees of crankshaft angle. Because the intake and exhaust camshafts are driven directly via a roller chain, this new system makes redundant the conventional three-stage chain drive between the crankshaft and the camshaft.
Porsche’s patented VarioCam can respond quickly to any sudden need for power or, conversely, to a more reserved style of driving, say in city traffic. This is possible because of the way it can make precise adjustments to valve opening and closing times. When running under part load, the intake camshaft is set to an earlier opening point. The residual gas remaining in the combustion chamber helps to reduce fuel consumption. When running under full load, the engine builds up maximum output through the small overlap in the opening and closing times. Maximum torque is provided by extended valve overlap and the earlier conclusion of the intake period.
Masterminding this system is the new Motronic ME 7.8 engine management program that was developed for the Porsche 911 Turbo. This system was conceived specifically for such high-performance requirements. It measures such parameters as engine speed, pedal position, engine oil and coolant temperatures and gear selection. It calculates the requisite position of the intake camshafts, and synchronization of intake camshafts on both rows of cylinders. This synchronization is ensured by its intelligent controls as the system intervenes in the fuel/air mixture formation and ignition.
Even with its boost in output, the engine itself is so strong that it didn’t need to be reworked. One secret of the strength of the Porsche “boxer” engine is its separate bearing bridge for the crankshaft, which has seven main bearings. This aluminum structure has cast steel support elements that provide a secure foundation for the crankshaft, even in widely varying temperature ranges. The integrated dry sump lubrication system carries over, although the output of the compressed oil pump has been increased by about 5 percent.
The Boxster’s engine also benefits from a “returnless” fuel supply system that reduces hydrocarbon emissions caused when fuel is heated prematurely as it flows back and forth to the engine through the traditional delivery system. Porsche engineers have developed a new and maintenance-free “returnless” fuel system that incorporates a pump, filter and pressure regulator in the fuel tank. The result is that only the fuel that is actually needed for optimum combustion is pumped to the engine. Excess fuel no longer enters the circuit and thus is not exposed to premature heating. A bonus from this system is that there is no need to replace the fuel filter as part of an owner’s routine maintenance.
For 2003, the Boxster sounds even better while producing more power using less fuel and with reduced emissions. Porsche engineers have carefully modified the interior of the car’s muffler to improve the car’s “acoustic presence.” The length and diameter of the various pipes and the perforation of the inner pipes were changed to satisfy not only legal sound limits but also the well-trained ear of the automotive enthusiast. The result is a muscular mix of sound that underscores the Boxster’s increased power and performance.
While the chassis, suspension (except for the application to the Boxster of the Boxster S’s higher-rate shock absorbers) and brakes carry over from the 2002 Boxster, the car’s handling can be enhanced with new, optional light-alloy wheels. The Boxster rides on standard 16-inch wheels, but 17- and 18-inch wheels are available as options. These optional wheels reduce unsprung weight and ensure smooth and sensitive response from shocks and springs. The 17-inch wheels reduce unsprung masses by more than half a pound per wheel. The 18-inch wheels, which were developed for the 911 Carrera, cut unsprung weight by more than five pounds per wheel. This weight reduction results in even crisper handling. Also optional on the Boxster is a sport suspension package that improves the car’s already amazing responsiveness through shorter and firmer springs, firmer and more responsive shocks and larger anti-roll bars.
There are several changes to the Boxster beneath its new electrohydraulic roof. For 2003, the list of standard equipment includes a new, 911-style cupholder that pops out of the instrument panel and a lighted and locking glove compartment. The cupholder is located just below the center air conditioning outlet. The glove compartment is located beneath the passenger-side airbag and has a capacity of 305 cubic inches (five liters). The glove box lock is connected to the car’s alarm system. The air-conditioner and heat controls have been moved from the console to the dash for easier accessibility and use, and instead of black leather, the steering wheel, gearshift lever, door handles and handbrake lever are covered in the same color leather as the seats. Color Porsche crests in the standard three-spoke steering wheel and the car keys add a classic design touch. Porsche’s new Communication Management system (PCM) comprises tuners, CD 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.
Also new for 2003 are remote unlocking front and rear trunks. Two trunks? That’s right. Although it’s a true roadster, the Boxster’s mid-engine placement provides space for storage areas at both ends of the vehicle. Together, these trunks offer an impressive 9.1 cubic feet of cargo capacity.
While the Boxster has been updated and upgraded for 2003, most of the basic components that have made the car so popular with sports car buyers remain unchanged. The 2.7-liter six-cylinder engine continues to provide real-world performance. It achieves its 192 lb.-ft. of peak torque at only 4,750 rpm and sustains it to nearly 6,000. Just as important, the powerplant delivers a significant 147 lb.-ft. of torque at only 1,750 rpm for powerful response even at low engine speeds.
In addition to the Porsche-patented VarioCam technology, the engine uses a lightweight aluminum cylinder block and heads and patented LOKASIL high-silicon cylinder liners that 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. Boxster customers can choose between the precisely shifting standard five-speed manual transmission and the optional Tiptronic® S five-speed automatic transmission. With the advanced Tiptronic S, the driver can place the shift lever into “D” and let the transmission do the shifting, or shift into “M” and control gear shifts with steering wheel-mounted thumb switches. In automatic mode, Tiptronic S uses one of several programmed shift maps to respond to the driving style. For example, during leisurely driving, Tiptronic S will up shift early to provide a quiet ride. Quicker stabs at the gas pedal will call up a sporty shift program, which holds each gear longer for response and power. 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 also allows the driver to select manual mode by pressing an up- or downshift button, even with the shift lever in the “D” position.
The racecar-inspired mid-engine layout concentrates the car’s mass near its center, providing quick response to steering inputs. Four-wheel independent suspension features a Porsche-optimized MacPherson-strut design for rigidity and aluminum components for low unsprung weight. Front and rear stabilizer bars and dual-tube gas-charged shock absorbers provide flat cornering. Standard power rack-and pinion steering yields a quick 2.98 turns lock-to-lock and a tight 35.8-ft. (10.9-meter) turning circle.
A “staggered” wheel/tire array (wider wheels and wider, lower-profile tires on the rear) contributes to neutral handling in the Boxster. The standard aluminum alloy wheels measure 16 x 6 inches in front and mount 205/55 ZR16 tires; the 16 x 7-inch rear wheels mount 225/50 ZR16 tires. Optional 17- and 18-inch wheel/tire packages enhance the already precise handling.
The Boxster stops with four-wheel vented disc brakes with ABS 5.3 anti-lock control. Derived from the Porsche GT1 racecar, one-piece “monoblock” brake calipers reduce heat and unsprung weight. The front discs measure 11.7 inches in diameter and 0.95-inch thick (298 mm x 24 mm). The rear discs measure nearly as large – 11.5 inches in diameter and 0.8-inch thick (292 mm x 20 mm).
The Boxster comes equipped with extensive standard comfort and convenience equipment, including:
• Boron-steel reinforced windshield header and A-pillars
• Dual-front and door-mounted side airbags
• Three-point inertial reel seatbelts with pre- tensioners and load limiters
• Fog lamps

Bose audio equipment was introduced in Porsches for 2002 and features equipment custom-engineered for each Porsche model. The new Bose automotive music systems combine balanced stereo, a panoramic sound stage, deep bass and smooth frequency response to produce lifelike music reproduction even in the challenging environment of a car interior. The Bose sound systems employ digital amplifiers to provide clean, uncolored sound at any listening level. In the Boxster, an array of 10 advanced loudspeakers blends seamlessly into cabin trim, raising and widening the sound stage and ensuring balanced stereo. Powerful bass speakers are concealed in customized enclosures to furnish superb performance within limited cabin space.
Safety in the Porsche Boxster starts with the body structure, which features front and rear crush zones that protect a reinforced passenger compartment. Boron steel tubing reinforcements inside the windshield header and A-pillars along with supplemental safety bars behind the seats provide additional safety in rollover accidents. The supplemental safety bars feature soft-touch covering for a high-quality appearance and tactile feel. Supplementing the three-point inertia-reel seatbelts, the Boxster features seatbelt pretensioners and load limiters as well as dual front airbags and the Porsche Side Impact Protection System that includes door-mounted side airbags, boron-steel door reinforcement beams, and energy-absorbing door panels. The 30-liter capacity side airbags provide additional protection for the chest, head, and pelvis.
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 install the system, the dealer also must reprogram the airbag control module.
The optional Porsche Stability Management system (PSM) can help keep the car going in the direction the driver steers – on slippery or dry road surfaces. PSM uses data from several sensor inputs to detect a loss of grip at the front or rear. The system can reduce instability by applying braking to individual wheels and, if necessary, altering engine power. In addition, the PSM system also provides a traction control function on slippery surfaces. 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.
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.
In addition to the standard power top, a three-piece wind deflector is available to reduce wind buffeting and noise during top-down driving.
Other options include an aluminum hardtop with a full lining and a glass rear window with defroster, and an innovative roof transportation system that attaches to the convertible roof (open or closed) or the optional hardtop. Suitable for carrying skis, kayaks, or bicycles, the system will hold up to 165 pounds.
The optional Porsche Communication Management system integrates controls and displays for Global Positioning Satellite (GPS) navigation, an onboard computer and climate control. A 5.8-inch (diagonal) LCD color screen displays all functions.
The Porsche Exclusive program offers a wide array of optional features installed at the factory. Options include custom interior trim packages and individual trim items. The Porsche four-year/50,000 mile bumper-to-bumper warranty covers all Exclusive options, and Porsche dealers can include the cost of the options in the lease or finance contract. The Tequipment® (“Tech-equipment”) program offers a line of accessories available only from authorized Porsche dealers. Tequipment options include such items as special wheels, an aerobody kit, instrument panel trim kits, CD changers, and custom floormats. Customers can order Tequipment options at the time of purchase, or return to the dealership for installation later. While installation of Tequipment may require some modifications to the car, such modifications do not affect the standard limited warranty. Tequipment items come with a two-year warranty when installed by a certified technician at an authorized Porsche dealership. Optional high-intensity, Bi-Xenon gas-discharge headlights increase lighting range and improve edge and side lighting.
Every new model-year 2003 Porsche car sold in the United States and Canada is covered by a four-year/50,000-mile (80,000 kilometer), bumper-to-bumper limited warranty, which includes Porsche’s roadside assistance program. The galvanized body and 26-step paint and anti-corrosion process enable Porsche to warrant each car against rust perforation for 10 years and unlimited mileage. In addition, Porsche guarantees the paint finish for three years – also without a mileage limitation.

PORSCHE® FAST FACTS
2003 BOXSTER®
The Boxster is a mid-engine roadster that takes its name from the union of Porsche’s classic, horizontally opposed six-cylinder “boxer” engine architecture with a roadster body. In the case of the Boxster, that body echoes such famous mid-engine Porsche sports and racing cars as the 550 Spyder and the RS60.
The Boxster was unveiled as a stunning concept car at the North American International Auto Show at Detroit in January 1993. After an overwhelmingly positive response from around the world -- and an extensive period of development and testing -- Porsche put its newest sports car into series production as a 1997 model.
Ever since the Boxster’s launch, the car has undergone continual enhancements. Those updates truly accelerate for 2003 with a more powerful engine, a new top with a glass window and a wider range of standard equipment. New front and rear fascia improve the car’s appearance as well as its performance efficiency.
Performance is enhanced even more with the availability of new light-alloy wheels that reduce unsprung weight. New VarioCam® technology and Motronic ME 7.8 engine management software increase the output of the Boxster’s 2.7-liter engine and also make the engine more fuel-efficient while reducing exhaust emissions. Horsepower increases to 225 horsepower (SAE) at 6,300 rpm (compared to 217 horsepower for the 2002 model). The engine’s torque figure remains 192 pound-feet at 4,750 rpm.
The 2003 Boxster can accelerate from a standing start to 100 km/h (62 mph) in only 6.4 seconds, an improvement of two-tenths of a second over the 2002 model.
But even with this improved performance, the Boxster gets better fuel mileage. For 2003, its EPA figures are 20 mpg in the city and 29 on the highway (compared to respective numbers of 19 and 27 in 2002) and 11.7 liter/100km and 7.4 for Canada. Those figures are for a Boxster with its standard five-speed manual transmission; the Tiptronic® S transmission is available and also shows performance improvements for the 2003 model year.
Refinements to the car’s styling contribute to these improved performance figures and also provide the Boxster with an even more contemporary -- and more 911®-like -- appearance. The lower section of the roadster’s face has been refined with enhanced side air intakes and a subtle redesign and extension of the front lip. These changes improve airflow through and around the car.
The redesigned convertible top has a fourth support bracket and a glass window with an electric defroster. The top still goes up or down in only 12 seconds, but its revised shape allows improved airflow to a redesigned rear spoiler that emerges from the car’s rear deck at 75 mph (120 km/h) and retracts at 50 mph (80 km/h).
The side-mounted air scoops that feed cooling air to the Boxster’s engine have been redesigned for improved efficiency and also have body-colored grids.
The rear section of the car gets new turn indicator light covers and a redesigned exhaust pipe that is flanked by thin but wide vents that enhance the car’s appearance while also providing more cooling airflow around the exhaust system.
For 2003 the Boxster gets the same shock absorbers as the Boxster S model, and the car’s performance can be further enhanced by the availability of new optional wheels. The Boxster comes with standard 16-inch wheels, but a new, optional 17-inch wheel is more than half a pound lighter than the 17-inch wheel that was available on the 2002 model. Also optional for 2003 is an 18-inch light-alloy wheel previously available on the 911 Carrera. This wheel reduces unsprung weight by nearly six pounds per wheel compared to the 18-inch wheel available in 2002.
Also new for the 2003 model year is Porsche’s new Communication Management system (PCM) that incorporates tuners, CD player, navigation system and trip computer, all connected to each other through the new Media-Oriented Systems Transport (MOST) digital databus. Completing the subtle but significant changes for the Boxster for 2003 are the addition of such standard features as a new, 911-style cupholder that pops out of the dashboard, remote unlocking front and rear trunks as well as the passenger doors, and a lighted and locking glove compartment. The air-conditioner and heat controls have been moved from the console to the dash for easier accessibility and use, and instead of black leather, the steering wheel, gearshift lever, door handles and handbrake lever are trimmed in the same color leather as the rest of the interior.
The Boxster continues to provide such safety technology as its patented crumple-zone body structure, inertia-reel three-point seatbelts with pretensioners and load limiters, dual front airbags, door-mounted side airbags and anti-lock brakes. Boron steel tubing reinforcements around the windshield and supplemental safety bars behind the seats help provide protection in rollover accidents. The Porsche Stability Management system (PSM) is available as an option. The Boxster’s unique combination of safety, performance and its additional new features for 2003 make the roadster an ideal sports car for everyday driving.
