Porsche 911 Targa 4 GTS 2017: 450-HP Open-Air Sport

The 2017 Porsche 911 Targa 4 GTS stands out as a pinnacle of engineering in the iconic 911 lineup, combining the freedom of open-top driving with the ferocious power and precision that define Porsche’s sports cars. This model introduces a turbocharged flat-six engine producing 450 horsepower, all-wheel drive for superior traction, and a clever retractable roof system that enhances its appeal for enthusiasts seeking both excitement and versatility.

Design and Exterior Highlights

Porsche’s designers crafted the Targa 4 GTS with aggressive styling cues that signal its performance intent. The broader bodywork and wider tracks provide a planted stance, while larger front air intakes improve cooling for the high-output engine. Satin-black center-lock wheels borrowed from the 911 Turbo and gloss-black tailpipes add a sinister edge, complemented by a distinctive black Targa bar that frames the rear glass wraparound.

The signature Targa roof features an automated removable panel that stows neatly, offering effortless conversion from coupe-like security to full open-air motoring. This setup, unique to the Targa, maintains structural integrity better than traditional convertibles, thanks to the robust roll bar and intelligent engineering. At 3,591 pounds for the manual version, it’s noticeably heavier than rear-wheel-drive coupes, but the design prioritizes both form and function.

Powertrain and Performance Specs

Central to the Targa 4 GTS is its 3.0-liter twin-turbocharged flat-six engine, upgraded with larger turbochargers—three millimeters bigger turbines and four millimeters larger compressors—delivering 450 horsepower at 6,500 rpm and 405 lb-ft of torque. Boost pressure rises to 18.1 psi from the Carrera S’s 16.0 psi, ensuring explosive response across the rev range.

Paired with either a seven-speed PDK dual-clutch automatic or a seven-speed manual, the powertrain shines. The PDK variant hits 60 mph in 3.5 seconds with launch control, while the manual matches it closely despite the weight penalty. All-wheel drive ensures massive grip, especially on hot pavement, with Porsche Torque Vectoring Plus distributing power dynamically.

Driving Dynamics and Handling

Behind the wheel, the Targa 4 GTS feels alive and engaging. Porsche Active Suspension Management (PASM) delivers a firm yet compliant ride, absorbing road imperfections while maintaining composure in Sport and Sport+ modes. On a skidpad, it achieves 1.03-1.09 g’s of lateral acceleration, showcasing its cornering prowess.

The all-wheel-drive system, combined with an electronically controlled limited-slip differential and brake-based torque vectoring, makes it forgiving and fast. It mimics rear-wheel-drive agility with added front-end security, allowing confident corner exits. Brakes, with six-piston fronts and cross-drilled rotors, halt from 70 mph in 148 feet without fade, even after repeated stops.

• Grip Levels: Exceptional traction from wide Pirelli P Zero tires and AWD.
• Steering: Precise and communicative, with optional rear-axle steering enhancing agility.
• Throttle Response: Linear and torquey from low rpm, peaking above 4,000 rpm.

In mountain roads, the PDK’s gearing keeps the engine in its powerband, perfect for twisty routes. The chassis shrugs off mid-corner lifts, quickly restoring balance via selective braking.

Interior Comfort and Technology

The cabin exudes premium quality with microsuede upholstery, supportive sports seats, and GTS-specific touches like unique gauges. The layout prioritizes driver focus, with controls falling readily to hand. Infotainment includes a responsive touchscreen, navigation, and Apple CarPlay compatibility in later updates.

Despite the open roof, wind buffeting is minimal at highway speeds, and the wraparound rear glass enhances visibility. Rear seats are vestigial but useful for light cargo. Fuel economy averages 17 mpg in mixed driving, reasonable for its performance.

Comparisons with Other 911 Variants

Compared to the rear-wheel-drive GTS coupe (lighter by 319 pounds), the Targa trades some sharpness for open-air appeal. The PDK coupe edges it in acceleration (3.0 seconds to 60), but the Targa’s AWD provides superior all-weather capability. Versus the standard Targa 4S, the GTS adds 30 hp and sportier tuning.

Pricing and Value Proposition

Starting around $150,000 in 2017, the Targa 4 GTS commanded a premium over coupes due to its roof mechanism and AWD. Options like PDK ($3,720), rear-axle steering ($2,090), and PASM quickly escalated costs. While not the lightest or cheapest 911, its blend of performance, style, and usability justifies the investment for open-top fans.

Pros and Cons

• Pros: Thrilling acceleration, impeccable handling, unique roof design, premium interior.
• Cons: Heavier than coupes, high price, firm ride on poor roads.
