INTRODUCTION
The Porsche Cayman S 3.4, part of the 987.2 generation (facelifted in 2009), built upon the foundation laid by its predecessor. The 987.2 series benefited from significant revisions, including a more powerful and efficient engine, a refined interior, and subtle styling updates. This model year saw Porsche address some criticisms of the original 987, particularly regarding engine responsiveness and interior quality. The S 3.4 variant was positioned as the sweet spot in the Cayman lineup, offering a substantial performance upgrade over the base model without the extreme focus of the Cayman R. It competed directly with other premium sports coupes like the BMW Z4 and Audi TT.
Powertrain & Engine Architecture
At the heart of the Cayman S 3.4 lies the MA1.21 engine, a naturally aspirated 3.4-liter flat-six (boxer) engine. This engine is a direct descendant of the engines used in the 997 generation Porsche 911, albeit detuned for the Cayman’s application. The key improvement in the 987.2 models was the introduction of Porsche’s Direct Fuel Injection (DFI) system. This system allowed for more precise fuel delivery, resulting in increased power, improved fuel economy, and reduced emissions. The engine produces 320 horsepower at 7200 rpm and 370 Nm (272.9 lb-ft) of torque at 4750 rpm. The engine features a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder. The 6-speed manual transmission was standard, providing precise and engaging shifts. While a PDK dual-clutch transmission was available as an option, the manual remained a popular choice among enthusiasts.
Driving Characteristics
The Cayman S 3.4 delivers a remarkably balanced and engaging driving experience. The mid-engine layout contributes to exceptional handling and a neutral chassis balance. The 3.4-liter engine provides ample power for both spirited driving on winding roads and comfortable cruising. Acceleration from 0 to 60 mph takes approximately 4.9 seconds, and the car reaches a top speed of 172.12 mph. The manual transmission’s gear ratios are well-matched to the engine’s power curve, providing strong acceleration in all gears. Compared to the base Cayman, the S 3.4 offers a noticeably more responsive and powerful experience. While not as raw or track-focused as the Cayman R, the S 3.4 provides a more accessible and enjoyable driving experience for a wider range of drivers.
Equipment & Trim Levels
The Cayman S 3.4 came standard with a generous array of features, including sport seats, a leather-wrapped steering wheel, automatic climate control, and a basic audio system. Optional extras were plentiful, allowing buyers to customize their cars to their preferences. Popular options included the Sport Chrono Package (which added a stopwatch, launch control, and a sport mode), the Bose audio system, and various interior trim options. Upholstery choices ranged from standard cloth to full leather, and buyers could select from a variety of interior colors. The standard dashboard layout was functional and driver-focused, with clear instrumentation and intuitive controls.
Chassis & Braking
The Cayman S 3.4 utilizes a McPherson strut suspension at both the front and rear, providing a good balance of comfort and handling. The suspension is tuned to provide a firm but compliant ride, allowing for confident cornering. The car is equipped with ventilated disc brakes at all four corners, providing ample stopping power. ABS (Anti-lock Braking System) is standard. The S 3.4 typically featured slightly thicker stabilizer bars compared to the base Cayman, further enhancing its handling capabilities. The car’s relatively low weight (1350 kg / 2976.24 lbs) contributes to its agility and responsiveness.
Market Reception & Comparison
The Cayman S 3.4 was generally well-received by automotive critics. It was praised for its balanced handling, powerful engine, and refined interior. Some critics noted that the steering lacked a bit of feel compared to older Porsche models, but overall, the car was considered a highly capable and enjoyable sports car. Compared to the base Cayman, the S 3.4 offered a significant performance upgrade for a relatively modest price increase. Fuel economy was respectable for a sports car of its caliber, averaging around 24 US mpg in combined driving. Reliability was generally good, although some owners reported minor issues with the DFI system over time.
Legacy
The Porsche Cayman S 3.4 (987.2) has established itself as a desirable used sports car. Its combination of performance, handling, and relative reliability has made it a popular choice among enthusiasts. The 3.4-liter engine is generally considered robust, although regular maintenance is essential, particularly regarding the DFI system. The 987.2 generation Cayman, and the S 3.4 variant in particular, represents a sweet spot in Porsche’s lineup, offering a pure and engaging driving experience at a more accessible price point than newer models. Today, well-maintained examples command a premium in the used car market, reflecting their enduring appeal.
