2017 Porsche 911 Targa (991 II) Dimensions, Size & Specs

The Porsche 911 Targa (991 II) has a curb weight ranging between 1570 kg and 1605 kg (3462 to 3538 lbs), depending on specific configurations and equipment. The maximum permissible weight, which includes passengers, cargo, and fluids, varies from 2000 kg to 2040 kg (4409 to 4496 lbs). This weight balance is carefully engineered to maintain dynamic handling and high performance characteristics expected of a Porsche sports car, ensuring it remains agile while providing stability and safety.

The luggage capacity of the Porsche 911 Targa (991 II) ranges from 125 liters to 160 liters (4.4 to 5.7 cubic feet) under normal conditions. When the rear seats are folded down, this capacity increases significantly, ranging from 160 liters to 285 liters (5.7 to 10 cubic feet). This flexibility allows owners to balance between passenger space and cargo-carrying ability, which is notably useful given the car’s nature as a sports cabriolet where space optimization is important.

Yes, the Porsche 911 Targa (991 II) comfortably fits in most standard residential garages. Standard garage widths usually measure around 2400 mm to 3000 mm (94.5 to 118 inches), and the Targa’s maximum width including mirrors is 1978 mm (77.9 inches), leaving ample clearance. The height of 1288–1293 mm (50.7–50.9 inches) also poses no issues for garage door clearances, which generally range from 2030 mm to 2440 mm (80 to 96 inches). Overall, parking and maneuvering in a typical garage environment is straightforward for this car.

The Porsche 911 Targa (991 II) is slightly wider than its predecessor, the 991 I generation. The 991 II's width at 1852 mm (72.9 inches) without mirrors and 1978 mm (77.9 inches) with mirrors accounts for improvements in aerodynamics and handling dynamics. The previous 991 generation measured about 1808 mm to 1852 mm width depending on the variant. This incremental increase in width enhances stability and cornering capability, attributes Porsche continuously refines with each generation while preserving the signature 911 silhouette.

Compared to similar sports cabriolets like the Audi R8 Spyder and the Mercedes-AMG GT Roadster, the Porsche 911 Targa (991 II) is generally more compact in length but offers a comparable width. For example, the Audi R8 Spyder measures approximately 4459 mm in length but is wider at about 1943 mm, while the AMG GT Roadster is longer around 4552 mm and wider at about 1930 mm. The Porsche strikes a balance with its length of roughly 4500 mm and width of 1852 mm, emphasizing a low profile and agility. This often translates into a more nimble driving experience on tight courses or urban environments, while competitors may offer more dramatic styling or interior space.

The Porsche 911 Targa (991 II) offers a range of rim sizes designed for different performance setups: 8.5J x 19 inch, 11.5J x 19 inch, 8.5J x 20 inch, 11.5J x 20 inch, 9J x 20 inch, and 12J x 20 inch. The corresponding tire sizes are 235/40 ZR 19 and 295/35 ZR 19 on 19-inch wheels, and 245/35 ZR 20 and 305/30 ZR 20 on 20-inch wheels. These wheel and tire combinations support excellent road grip and handling capabilities, tailored for high-performance driving and enhanced stability in both everyday and spirited conditions.

The 991 II Targa is distinguished by its innovative roof design that blends the classic Targa roof look with modern engineering. It features a fully retractable glass roof panel that slides under a fixed roll bar, giving the option of open-air driving without compromising structural rigidity. This design retains the iconic roll bar of traditional Targa models but integrates modern materials and mechanisms for convenience. Additionally, the Targa has subtle aesthetic cues including unique badging and rear end treatment that set it apart from coupe and cabriolet variants, making it a standout in the 911 range.

Compared to the predecessor 991 I Targa, the 991 II iteration typically offers minor increases in length and width, coupled with weight reductions due to improved lightweight construction techniques and use of advanced materials such as aluminum and composites. These changes contribute to a lower center of gravity and optimized weight distribution, enhancing cornering precision and overall handling. Although curb weights fall in a similar range (around 1570–1605 kg for the 991 II), the balance and chassis tuning improvements result in a more responsive driving experience, better road feedback, and enhanced sportscar agility.

Despite being a sports-oriented cabriolet, the Porsche 911 Targa (991 II) offers a reasonably practical interior for daily use. Seating is designed for comfort with supportive sport seats, and while the rear area is limited, it can accommodate smaller passengers or additional cargo when the rear seats are folded. Interior dimensions are balanced to maintain driver engagement without feeling cramped, and the enhanced luggage space (125-160 liters, expandable to 160-285 liters with seats folded) supports daily errands or weekend trips. The compact height and width contribute to ease of entry and exit while preserving an engaging driving position typical of a Porsche 911.
