Powertrain & Engine Architecture
At the heart of the 911 Targa 4 3.4 PDK lies the MA1.04 engine, a 3.4-liter naturally aspirated flat-six. This engine benefits from Porsche’s direct fuel injection (DFI) system, delivering precise fuel metering for optimal combustion and efficiency. The engine’s valvetrain utilizes four valves per cylinder, contributing to its high-revving nature and impressive power output. The 350 horsepower peak is achieved at 7400 rpm, while the 390 Nm (287.65 lb-ft) of torque is readily available at 5600 rpm. The engine’s boxer configuration, with horizontally opposed cylinders, contributes to a lower center of gravity, enhancing handling stability. Paired with this engine is Porsche’s seven-speed PDK (Porsche Doppelkupplung) dual-clutch transmission. This transmission offers incredibly fast and smooth gear changes, whether in automatic or manual mode, contributing to both performance and driving enjoyment. The PDK is specifically tuned to work in harmony with the all-wheel-drive system, optimizing power distribution for maximum traction.
Driving Characteristics
The 911 Targa 4 3.4 PDK delivers a refined yet engaging driving experience. The all-wheel-drive system provides exceptional grip, particularly in adverse weather conditions, making it a more practical option than rear-wheel-drive 911 variants. While not as brutally quick as the higher-output Carrera S models, the 350 hp engine provides ample power for spirited driving. The PDK transmission allows for seamless acceleration, and the driver can select different driving modes – including Sport and Sport Plus – to adjust the transmission’s shift points and throttle response. The Targa top, with its automated folding mechanism, adds a unique open-air element without sacrificing structural rigidity. Compared to a manual transmission equipped 911 Targa, the PDK offers quicker acceleration and a more accessible driving experience for a wider range of drivers.
Equipment & Trim Levels
The 911 Targa 4 3.4 PDK came standard with a generous array of features, including leather upholstery, automatic climate control, a high-quality audio system, and Porsche’s Communication Management (PCM) infotainment system. The Targa model also featured the signature Targa roll bar, finished in brushed aluminum. Optional extras included adaptive sport seats, a sunroof, and various customization options for interior trim and exterior paint. The Targa typically sat in the mid-range of the 991 lineup, offering a step up in luxury and features compared to the base Carrera, but without the outright performance focus of the Carrera S or GTS models.
Chassis & Braking
The 911 Targa 4 3.4 PDK utilizes a sophisticated chassis design, featuring independent suspension at all four corners. The front suspension employs a McPherson strut setup, while the rear utilizes a multi-link system. This configuration provides excellent ride comfort and precise handling. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. ABS (Anti-lock Braking System) is standard, enhancing safety and control. The all-wheel-drive system contributes to stability during braking, particularly on slippery surfaces.
Market Reception & Comparison
The 911 Targa 4 3.4 PDK was generally well-received by automotive critics. It was praised for its blend of performance, luxury, and open-air driving experience. Compared to the Carrera models, the Targa offered a more unique and sophisticated aesthetic. Fuel economy was respectable for a sports car of its caliber, averaging around 27 US mpg in combined driving. Reliability was generally good, consistent with Porsche’s reputation for engineering excellence. However, the Targa’s higher price point compared to the Coupe and Cabriolet models was a point of consideration for some buyers.
Legacy
The 911 Targa 4 3.4 PDK remains a desirable vehicle in the used car market. The MA1.04 engine is known for its durability and relatively straightforward maintenance. The PDK transmission, while complex, has proven to be reliable when properly maintained. The Targa’s unique styling and all-wheel-drive capability continue to appeal to enthusiasts seeking a distinctive and capable sports car. These models represent a sweet spot in the 991 generation, offering a compelling combination of performance, luxury, and everyday usability.
