Powertrain & Engine Architecture
At the heart of the 911 Targa 4 3.6 Tiptronic S lies the M96.05 3.6-liter naturally aspirated flat-six engine. This engine, a hallmark of Porsche engineering, features a dry-sump lubrication system, crucial for maintaining oil supply during the high G-forces experienced in spirited driving. The engine utilizes multi-port fuel injection, delivering precise fuel metering for optimal combustion. The valvetrain employs four valves per cylinder, enhancing breathing and contributing to the engine’s power output. The Tiptronic S transmission is a five-speed automatic with a torque converter, offering both fully automatic operation and manual gear selection via steering wheel-mounted paddles or the gear selector. This transmission was designed to provide smooth shifts and responsive performance, although it wasn’t as quick or engaging as the available six-speed manual.
Driving Characteristics
The 911 Targa 4 3.6 Tiptronic S delivers a refined and capable driving experience. While not as brutally quick as the Carrera S variants, the 325 horsepower and 370 Nm (273 lb-ft) of torque provide ample power for both everyday driving and enthusiastic excursions. The Tiptronic S transmission, while smooth, does introduce a slight loss of responsiveness compared to the manual gearbox. The all-wheel-drive system provides excellent traction, particularly in inclement weather, making this Targa a practical year-round vehicle. The gear ratios are tuned for a balance of acceleration and fuel efficiency, with the automatic transmission generally selecting the appropriate gear for the driving conditions. However, drivers seeking maximum control may prefer the more direct engagement of the manual transmission.
Equipment & Trim Levels
The Targa 4 3.6 Tiptronic S came standard with a generous array of features, including leather upholstery, automatic climate control, a Bose sound system, and Porsche Stability Management (PSM). Optional extras included navigation, sport seats, a sunroof, and various customization options through Porsche’s “Personalization” program. Interior trim options ranged from standard leather to more luxurious materials like Alcantara. The dashboard layout was typical of the 997 generation, with a central tachometer flanked by gauges for speed, fuel level, and coolant temperature.
Chassis & Braking
The 997 Targa 4 utilizes a fully 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 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 during emergency braking situations. The Targa 4’s chassis is reinforced compared to the standard Carrera, due to the structural changes required for the retractable roof mechanism.
Market Reception & Comparison
The 911 Targa 4 3.6 Tiptronic S was generally well-received by automotive critics. It was praised for its blend of performance, comfort, and all-weather capability. However, some reviewers noted that the Tiptronic S transmission wasn’t as engaging as the manual gearbox, and the fuel economy was relatively poor compared to other sports cars. Compared to the 911 Carrera 4, the Targa 4 offered a unique open-air experience, but at a slight weight penalty. Compared to the more powerful Carrera S models, the Targa 4 provided a more accessible entry point into the 911 range.
Legacy
The M96.05 engine, while generally reliable, is known to be susceptible to intermediate shaft (IMS) bearing failure, a potential issue that should be addressed by any prospective buyer in the used car market. Regular maintenance and oil changes are crucial for ensuring the longevity of this engine. The Tiptronic S transmission is generally reliable, but can be expensive to repair if issues arise. Today, the 911 Targa 4 3.6 Tiptronic S remains a desirable sports car, offering a unique combination of style, performance, and practicality. Its values have been steadily increasing in recent years, reflecting the enduring appeal of the Porsche 911.
