2017 Porsche 718 Cayman (982) Dimensions, Size & Specs

The Porsche 718 Cayman (982) has a width ranging from 1778 mm to 1822 mm (about 70 to 71.7 inches) without the mirrors. When the side mirrors are opened, the width expands to 1994 mm (roughly 78.5 inches). This difference is important to note for assessing parking and garage space requirements. The wider stance with mirrors open enhances visibility, crucial for the driver's safety, but requires extra width clearance when parking or driving through tight spaces.

The height of the Porsche 718 Cayman (982) ranges from 1238 mm to 1295 mm (approximately 48.7 to 51 inches). This low height is typical for sports cars as it helps lower the center of gravity, enhancing handling and stability on the road and track. Such a slim profile also contributes to aerodynamic efficiency, which is a key factor in the car's performance and fuel economy.

The Porsche 718 Cayman (982) has a curb weight between 1320 kg and 1464 kg, equivalent to approximately 2910 to 3227 pounds. The maximum weight ranges from 1450 kg to 1780 kg (about 3197 to 3924 pounds), which includes passengers and cargo. The curb weight reflects the car's weight without occupants or additional load. These figures indicate a relatively light sports coupe, which favors agility, acceleration, and braking performance.

The Porsche 718 Cayman (982) offers luggage capacity ranging from 150 liters to 420 liters (approximately 5.3 to 14.8 cubic feet). When rear seats are folded, which applies more to models with split rear storage capability rather than a full rear seat, the capacity is between 136 liters and 425 liters (roughly 4.8 to 15 cubic feet). Such cargo space is moderate and typical for a coupe, sufficient for small luggage, groceries, or weekend bags, emphasizing the car's focus on driving experience over utility.

The Porsche 718 Cayman (982) has a ride height or ground clearance of 102 mm, which is about 4 inches. This low ground clearance is ideal for sports car dynamics—it lowers the vehicle's center of gravity, improves aerodynamics, and enhances the car's handling and responsiveness. However, it may require extra caution when navigating speed bumps, steep driveways, or uneven road surfaces to avoid scraping the undercarriage.

Given the Porsche 718 Cayman (982)'s length of up to 4456 mm (14.62 feet), width up to 1994 mm (78.5 inches) with mirrors open, and height up to 1295 mm (51 inches), it generally fits comfortably within a standard home garage. Typical garages are around 6 meters (20 feet) long and 3 meters (10 feet) wide, which provides ample room for parking. However, careful mirror folding is recommended to avoid damage when maneuvering in tighter garage spaces. In summary, parking the Cayman in a standard garage shouldn't pose a problem for most homeowners.

Compared to the predecessor 987 Cayman, the 718 Cayman (982) is slightly larger in overall dimensions. The 987 measured around 4320 mm (approximately 14.17 feet) in length versus 4379 to 4456 mm (14.37 to 14.62 feet) in the 718. The width also increased from around 1762 mm (69.4 inches) to a range of 1778 mm to 1822 mm (70 to 71.7 inches), not including mirrors. These incremental size increases provide additional interior space and improve road presence while maintaining the Cayman’s characteristic nimble driving dynamics. The 718 generation also features updated styling and enhanced performance, making it an evolution rather than a revolutionary redesign.

The Porsche 718 Cayman (982) is generally more focused on driving dynamics and precision than some competitors like the Audi TT or BMW Z4. Dimensionally, the Cayman is similar or slightly longer and wider; for example, the Audi TT measures about 4178 mm in length (164.5 inches), making the Cayman larger by roughly 200 mm (about 8 inches). The BMW Z4 is comparable in length to the Cayman but often taller owing to its roadster format. Performance-wise, the Cayman’s mid-engine layout aids balanced handling and agility, versus front-engine layouts in the TT and Z4. This makes the 718 Cayman a preferred choice for enthusiasts seeking sharp handling, though competitors may offer more comfort or daily usability.

The Porsche 718 Cayman (982) supports a variety of rim sizes: 18-inch (8J or 9.5J), 19-inch, and 20-inch options, including widths from 8J to 10.5J, with offsets (ET) in the range of 45 to 57. Tires range from 235/45 ZR 18 to 295/30 ZR 20 in various configurations. Larger rims and wider tires provide increased grip and stability in cornering but can slightly impact ride comfort. Porsche’s range allows customization based on driving preferences—18-inch rims for a balanced daily drive with comfort, and 19- or 20-inch rims for enhanced sportiness and track readiness. The appropriate tire selection is critical to maximize grip, braking, and responsiveness of this sports coupe.
