2005 Porsche Boxster (987)

Exterior design, changes, features, and dimensions

Marking its debut for its 987 generation, the 2005 Porsche Boxster arrived with a redesigned shell style, bidding farewell to the controversial 986 generation known for its divisive "fried egg" headlamp design shared with the 996-generation 911. The 2005 iteration brought evolutionary styling updates while retaining the Boxster’s iconic silhouette, distinguishing it from its coupe sibling – the Cayman.

Porsche’s designers refreshed the Boxster’s front end, drawing inspiration from the 911 and the Carrera GT supercar. Separate main headlights and integrated fog lights gave the roadster a distinctive and purposeful look, while enlarged side air intakes ahead of the rear wheels hinted at the car’s performance potential. Prominent new door sills emphasized the Boxster’s low, wide stance and enlarged wheel arches accommodated wheels up to 19 inches in diameter.

At the rear, a larger window connecting the B-pillar to the convertible top improved visibility and created a sleeker profile. The automatic rear spoiler enhanced high-speed stability and provided additional downforce, while the convertible soft top featured a heated glass rear window for added comfort and visibility. Customers could personalize their Boxster with metallic and special colors, color-matched hardtops, and roll bars.

Beneath the skin, the Boxster’s aerodynamics were further optimized, with a reduced drag coefficient of 0.29, underbody paneling, and a rear diffuser for improved airflow. These enhancements not only contributed to the car’s efficiency but also its stability at high speeds.

Despite these improvements, some critics argued that the 987.1 Boxster’s design lacked the boldness and innovation expected from a Porsche. While the updated styling addressed many of the 986’s shortcomings, it remained evolutionary rather than revolutionary. However, most enthusiasts appreciated the Boxster’s refined appearance and Porsche’s efforts towards retaining its signature Porsche design cues, treasuring the Boxster’s timeless aesthetics.

Interior design, comfort, and features

Porsche completely redesigned the Boxster’s interior for the 987 generation, addressing many of the criticisms leveled at its 986 predecessor. Upon stepping inside, drivers were greeted by a cockpit prioritizing functionality and ergonomics. The circular theme, evident in the three-gauge instrument cluster and air vents, paid homage to Porsche’s rich heritage while providing a modern twist. High-quality materials, such as the durable leather-like materials on the dashboard, door panels, and center console, added a premium touch to the interior.

One of the standout features of the Boxster’s cabin was its driver-focused layout. The ignition, located to the left of the steering wheel, harks back to Porsche’s racing roots, while the short-throw gear shifter and perfectly placed pedals encouraged spirited driving. The standard leather-wrapped three-spoke steering wheel provided excellent feedback and control, with optional multifunction controls and heating for added convenience.

Comfort and convenience features were not overlooked in the Boxster’s two-seater interior. Standard equipment included supportive leather power bucket seats, optional adaptive sport seats, and seat heating for those seeking a more personalized fit. Automatic climate control and a digital clock with an onboard computer kept occupants comfortable and informed, while optional aluminum or carbon fiber interior accents promised a luxurious touch. Safety was a top priority in the Boxster’s design, with the Roadster being the world’s first to offer head airbags for side impact protection.

Despite its focus on driving enjoyment, the Boxster’s cabin had some drawbacks. The compact interior, while cozy, felt cramped for taller occupants, particularly during longer journeys. With seats for just two, it was less practical than the 2005 Porsche 911 Cabriolet. Storage space was also limited, with 9.2 cubic feet total cargo space (5.3 cubic feet front trunk and 3.9 cubic feet rear trunk). Smaller door pockets and a compact glove compartment made it challenging to store larger items.

Another point of contention for some buyers was the Boxster’s sound insulation. While the convertible top kept wind noise at bay, road and engine noise could become pronounced at higher speeds, especially with the optional sport exhaust system.

For infotainment, Porsche outfitted the cockpit with an AM/FM/single-disc CD/cassette player and a basic audio system. Buyers could also opt for a PCM infotainment system, which added a 5.8-inch display, navigation, and hands-free phone preparation. A seven-speaker Porsche premium audio system was optional for buyers looking for an inexpensive audio upgrade, but audiophiles could go for a Bose 11-speaker surround audio set.

Engine specs, performance, and fuel economy

For its 987.1 generation, the 2005 Boxster received a significant boost in performance thanks to its updated powerplant. Lurking underneath this mid-engine convertible was a 2.7-liter naturally aspirated boxer-six engine, designated as the M96.25. This powerplant was tuned to produce 240 horsepower at 6,400 rpm and 199 pound-feet of torque at 4,700 rpm, marking a 15 horsepower and seven pound-feet increase over the 986 generation or 2004 model’s engine. Three transmission choices were offered with updated five- or six-speed manual gearboxes and a five-speed Tiptronic S automatic transmission, all revised for higher durability and crisper shifts.

As for performance, the 987.1 Boxster clocked 0-60 mph in 5.9 seconds and had a top speed of 159 mph with the manual gearboxes. The Tiptronic S needed 6.8 seconds for the chore and maxed out at 155 mph. Economy was decent, with 18 mpg (city) and 27 mpg (highway) from the manuals and 16 mpg (city) and 24 mpg (highway) with the automatic. A 16.9-gallon tank offered around 456.3 miles on the highway.

When compared to its rivals, the Boxster’s performance figures fell short. The Lotus Elise, with its lightweight chassis and high-revving 190-horsepower 1.8-liter inline-four, delivered 0-60 mph in just 4.9 seconds – a second slower, but it had a lower top speed of 141 mph due to federal regulations. On the other hand, the 2005 Audi TT Quattro Roadster’s 3.2-liter V6 churned out 250 horsepower and 236 pound-feet, but its heavier curb weight affected its handling and acceleration. It clocked 0-60 in 6.1 seconds and had a top speed of 157 mph.

Rivals thrashed the Boxster with a superior fuel economy. The Elise’s 1.8-liter presented 23 mpg (city) and 27 mpg (highway), while the TT Roadster 3.2 was rated at 22 and 27 mpg, respectively.

One notable omission from the Boxster’s options list was a power kit, which could have appealed to buyers seeking even greater performance without stepping up to the more expensive Boxster S model. This left enthusiasts who desired more power with either opting for the Boxster S or turning to aftermarket modifications.

How was the handling and maneuverability of the 2005 Porsche Boxster?

The 2005 Porsche Boxster shared 55 percent of its parts with the 911 Carrera, and this was evident in its exceptional handling characteristics. The mid-engine layout and rear-wheel drive configuration provided optimal weight distribution, resulting in a well-balanced and responsive driving experience. Porsche strengthened the Boxster’s body structure, enhancing both handling and safety.

This model received variable-ratio steering for the first time, treating drivers with a well-weighted feel, precise steering, and sufficient feedback. Standard Porsche-optimized front and rear suspension kept this car planted at high speeds, whilst providing an aggregable ride quality. Porsche Stability Management (PSM) came standard, providing an added layer of safety and control in challenging driving conditions.

Buyers seeking a creamier ride quality or firmer tunings could outfit Porsche Active Suspension Management adaptive dampers, but they required a premium. Adjustable-anti roll bars and 18- or 19-inch wheels provided more stability at higher speeds, but the larger wheel sizes resulted in a firmer ride. The Sport Chrono Package further enhanced the Boxster’s performance with a more aggressive throttle map, sportier suspension settings, dynamic engine mounts, and launch control.

For braking performance, the Boxster’s four-piston fixed calipers and 11.7-inch ventilated discs provided strong and consistent stopping power. For even greater braking capabilities, Porsche offered optional Porsche Composite Ceramic Brakes (PCCB), which delivered fade-resistant performance and reduced unsprung weight.

Further bolstering its handling credentials were its compact dimensions. The short wheelbase While the compact body and 95.1-inch wheelbase contributed to its nimble handling and a light curb weight of just 2,855 pounds (manual), it also resulted in a firmer ride compared to larger sports cars. Some drivers might have found the ride quality too stiff for daily driving, especially on rough or uneven roads. Some enthusiasts wished for more traction and stability of an all-wheel-drive system, like the one found in the 911 Carrera 4, which could have provided more grip, especially in wet or slippery conditions.

Problems and reliability

While the Porsche Boxster 987 generation offered a thrilling driving experience and iconic Porsche design, it’s overall reliability was questionable. As a luxury sports car, the Boxster required meticulous maintenance and could be prone to expensive repairs, especially for major problems.

One of the most significant concerns was the M96 engine, which had a history of catastrophic failures due to the intermediate shaft (IMS) bearing issue. Although Porsche addressed this problem in later years, 2005 models were still susceptible to IMS failure, which could result in costly engine rebuilds surpassing tens of thousands of dollars. Other engine-related problems included scored cylinder bores, oil leaks from the rear main seal (RMS), and failing air-oil separator (AOS) units.

Transmission and drivetrain issues were another area of concern for the 987 Boxster. Some owners reported problems with the manual and Tiptronic S gearboxes, such as clicking sounds, humming noises, stiff gear changes, and heavy clutch pedals. These issues could be attributed to the long service intervals recommended by Porsche, which allowed problems to go unnoticed until extensive repairs were needed.

Mechanical problems extended beyond the engine and transmission, with suspension components like coil springs and bushings prone to failure. Worn or broken coil springs were a common reason for MOT failures while failing suspension bushings could lead to accelerated tire wear and squeaking noises over bumps. Electrical issues like malfunctioning window regulators and faulty oxygen sensors and problems with the car’s various electronic systems also plagued the 987.

Other potential problems buyers should be aware of include corroded coolant radiators and air conditioning condensers due to clogged front vents, cracked exhaust manifolds, and damaged or leaking convertible roof mechanisms.

Things to watch out for

When considering a 2005 Porsche Boxster, thorough research and careful inspection are crucial. First, seek out examples with comprehensive service histories, preferably maintained by Porsche specialists. A pre-purchase inspection by a qualified Porsche technician is essential, including a borescope examination of the engine to check for potential IMS bearing issues or scored cylinders.

Look for cars with documented IMS bearing replacements or upgraded bearings, as this can provide peace of mind. Avoid suspicious low-priced examples, as they may have hidden issues or accident histories. Check for signs of water damage, particularly around the footwells and under the carpets. Test drive the car to assess transmission smoothness, suspension condition, and overall performance. Listen for unusual noises from the engine or drivetrain. Inspect the convertible top mechanism for proper operation and any signs of leaks.

Once purchased, maintain your Boxster religiously. Follow Porsche’s recommended service intervals or consider more frequent oil changes to protect the engine. Address issues promptly to prevent minor problems from escalating into major repairs. Consider joining a Porsche club or online forum for advice and support from experienced owners.

Remember, while a well-maintained 987 Boxster can provide years of driving pleasure, it’s a high-performance sports car that requires attentive care and can incur significant maintenance costs. Budget accordingly for both routine upkeep and potential repairs.

Should you buy a used 2005 Porsche Boxster?

Porsche’s 2005 Boxster offered a compelling blend of performance, style, and open-top thrills. Its mid-engine layout and precise handling provided a driving experience that rivaled more expensive sports cars. Compared to the Lotus Elise’s raw athleticism or the Audi TT Quattro’s all-weather capability, the Boxster balanced everyday usability and weekend fun.

However, potential buyers face a dilemma. While a used 987.1 Boxster could be an enticing proposition for Porsche enthusiasts, it comes with significant risks. Engine issues, particularly the infamous IMS bearing problem, loomed large over early models. Maintenance costs often exceeded those of more mainstream sports cars, and finding a well-cared-for example requires diligence.

For those willing to accept the challenges, a properly maintained 987 Boxster rewards buyers with its engaging dynamics and timeless design. The hardtop Cayman offers similar thrills with added rigidity but lacks the Boxster’s open-air appeal. Ultimately, the decision to purchase a used 987 Boxster hinged on the buyer’s willingness to invest in preventative maintenance and potentially costly repairs.
