Powertrain & Engine Architecture
At the heart of the 911 Targa 4 3.4 lies the MA1.04 engine, a 3.4-liter naturally aspirated flat-six (boxer) engine. This engine benefits from direct fuel injection, a technology that improves both power and fuel efficiency by precisely controlling the amount of fuel delivered to each cylinder. The engine produces 350 horsepower at 7,400 rpm and 390 Nm (287.65 lb-ft) of torque at 5,600 rpm. The boxer configuration, with its horizontally opposed cylinders, contributes to a low center of gravity, enhancing stability and handling. The engine is paired with a seven-speed manual transmission, delivering power to all four wheels via Porsche’s sophisticated all-wheel-drive system. This system intelligently distributes torque between the front and rear axles, optimizing traction in various driving conditions.
Driving Characteristics
The 911 Targa 4 3.4 offers a refined and engaging driving experience. While not as overtly aggressive as the Carrera S models, the 350 hp engine provides ample power for spirited driving. The all-wheel-drive system ensures confident handling, particularly in inclement weather. The seven-speed manual transmission offers precise shifts and allows the driver to fully engage with the car’s performance. Compared to the base Carrera Targa, the ‘4’ model provides noticeably improved grip and stability, making it a more forgiving and confidence-inspiring car to drive at the limit. The power delivery is linear and predictable, making it easy to modulate throttle inputs.
Equipment & Trim Levels
The 911 Targa 4 3.4 came standard with a generous array of features, including leather upholstery, automatic climate control, a high-quality audio system, and Porsche’s Communication Management system with a touchscreen display. Optional extras included adaptive sports seats, a sunroof, and various customization options for interior trim and exterior paint. The Targa model specifically featured the iconic retractable roof, which could be opened or closed electrically, providing a unique open-air experience.
Chassis & Braking
The 991 generation 911 Targa utilizes an independent suspension system, with McPherson struts at the front and a multi-link setup at the rear. This configuration provides a comfortable ride while maintaining excellent handling characteristics. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Porsche’s ABS (Anti-lock Braking System) is standard, enhancing safety and control during emergency braking situations. The chassis is constructed from a combination of steel and aluminum, optimizing both strength and weight.
Market Reception & Comparison
