2004-2006 Porsche Boxster (987) 2.7 (240 Hp)

The Porsche Boxster (987) 2.7, introduced in October 2004 and continuing through August 2006, represented a significant evolution in Porsche’s mid-engine roadster lineup. Positioned as the base model within the 987 generation, it offered a more accessible entry point into the Porsche experience compared to the higher-performance 987 S. The 2.7-liter variant aimed to balance the classic Porsche driving experience with improved everyday usability and a slightly lower price tag. It was built on the 987 platform, sharing its core structure with the contemporary Porsche 911 (997) but distinguished by its open-top roadster configuration and mid-engine layout.

Powertrain & Engine Architecture

The heart of the 987 Boxster 2.7 is the M96.25 engine, a 2.7-liter naturally aspirated flat-six (boxer) engine. This engine utilizes a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder, contributing to its relatively high specific output. Fuel delivery is managed by a multi-port fuel injection system. The engine’s boxer configuration, with horizontally opposed cylinders, contributes to a low center of gravity, enhancing handling characteristics. The 987 Boxster 2.7 was exclusively offered with a 5-speed manual transmission. This transmission was chosen for its direct feel and engagement, aligning with Porsche’s focus on driver involvement. The gearbox featured relatively short ratios, optimized for acceleration and responsiveness.

Driving Characteristics

The 2.7-liter Boxster offered a distinct driving experience compared to the more powerful ‘S’ variant. While not as brutally quick, the 2.7 provided a smooth and accessible power delivery. Peak torque of 199 lb-ft arrived at 4700-6000 rpm, making it reasonably flexible in everyday driving situations. The 5-speed manual transmission, while not offering the close ratios of some competitors, provided a satisfying mechanical feel. The car’s mid-engine layout and well-tuned suspension resulted in excellent balance and handling. Steering was precise and communicative, providing ample feedback to the driver. The 2.7 was often praised for its composure and predictability, making it a confidence-inspiring car to drive on both winding roads and open highways.

Equipment & Trim Levels

The base 987 Boxster 2.7 came reasonably well-equipped, though Porsche offered a substantial options list for personalization. Standard features included air conditioning, power windows and locks, a basic audio system, and partial leather upholstery. Optional extras were plentiful, ranging from upgraded audio systems (including Bose and Porsche Communication Management), to sport seats, heated seats, and various cosmetic enhancements. Interior trim options included different leather colors and materials. The dashboard layout was functional and driver-focused, with clear instrumentation and logically placed controls.

Chassis & Braking

The 987 Boxster featured an independent suspension system at all four wheels, utilizing McPherson struts. This setup provided a good balance between ride comfort and handling precision. The chassis was constructed from a combination of steel and aluminum, contributing to a relatively lightweight structure. Braking duties were handled by ventilated disc brakes at all four corners, providing ample stopping power. Anti-lock braking system (ABS) was standard. The base model typically featured smaller diameter rear rotors compared to the ‘S’ variant.

Market Reception & Comparison

The 987 Boxster 2.7 was generally well-received by automotive critics. It was praised for its handling, steering feel, and overall driving experience. Some reviewers noted that the 2.7-liter engine, while capable, lacked the outright punch of the 3.2-liter engine found in the ‘S’ model. However, the 2.7 was considered a more practical and affordable option for those seeking a Porsche roadster. Fuel economy was respectable for a sports car, averaging around 24.5 mpg in combined driving. Compared to the 987 Boxster S, the 2.7 offered a lower price of entry, but sacrificed some performance. Compared to other roadsters in its class, such as the BMW Z4 and Mercedes-Benz SLK, the Boxster 2.7 was often lauded for its superior handling and mid-engine balance.

Legacy

The M96.25 engine, while generally reliable, has been known to exhibit some issues over time, particularly related to intermediate shaft (IMS) bearing failure. Preventative IMS bearing upgrades are commonly performed on these engines to mitigate this risk. Overall, the 987 Boxster 2.7 has proven to be a durable and enjoyable sports car. On the used car market, well-maintained examples command reasonable prices, making them an attractive option for enthusiasts seeking an accessible Porsche experience. The 987 generation, including the 2.7 variant, is considered a significant step forward in Porsche’s roadster lineage, offering a compelling blend of performance, handling, and everyday usability.
