# 2025 Porsche 911 Carrera 4 GTS Cabriolet: All-Wheel Drive Test Results
Porsche's 2025 911 Carrera 4 GTS Cabriolet delivers 541 horsepower and 531 lb-ft of torque from its 3.0-liter twin-turbocharged flat-six engine. The all-wheel-drive system adds approximately 100 pounds over the rear-wheel-drive Carrera GTS, pushing the convertible's curb weight to roughly 3,600 pounds. The eight-speed dual-clutch transmission remains unchanged from the standard model.
The critical question centers on whether the added complexity and weight justify the AWD option's premium pricing. Testing reveals the Carrera 4 GTS delivers superior traction off-line and in low-grip conditions compared to its RWD sibling. Acceleration from standing starts benefits from front-tire grip, though the gap narrows at highway speeds where weight becomes the limiting factor. Dry handling remains sharp, with the system's torque vectoring providing predictable mid-corner behavior without the sharp responses characteristic of rear-wheel-drive sports cars.
On wet surfaces, the Carrera 4 GTS cabriolet demonstrates measurable confidence gains. The front axle grips harder during spiral testing, and stability control intervention occurs later in extreme maneuvers. Braking distances tighten slightly due to all four tires sharing load more evenly during deceleration events.
Convertible buyers face a specific calculus. The open-air experience requires compromise regardless of drivetrain choice. All-wheel-drive ownership costs more upfront and reduces fuel economy by roughly 2 miles per gallon. The softer suspension tuning expected of the GTS variant
