2019 Porsche Cayenne III Coupe Dimensions, Size & Specs

The Porsche Cayenne III Coupe has a curb weight ranging from 2030 kg to 2535 kg (4473 to 5588 pounds), depending on the specific variant and options installed. The maximum permissible weight lies between 2765 kg to 3095 kg (6096 to 6823 pounds). This weight spectrum means the vehicle balances the heft required for SUV stability with Porsche's emphasis on dynamic, sporty performance. Heavier curb weight tends to deliver more stability on highways, while still maintaining responsive handling, thanks to Porsche's advanced chassis tuning and adaptive suspension options.

The luggage capacity of the Porsche Cayenne III Coupe varies with the seat configuration. With rear seats in place, it offers between 460 to 625 liters (16.2 to 22.1 cubic feet) of cargo space, suitable for everyday needs such as groceries or small luggage. When the rear seats are folded down, the available space expands significantly to between 1400 and 1540 liters (49.4 to 54.4 cubic feet), making it capable of accommodating larger items or more extensive cargo for trips. This flexible cargo solution makes the Cayenne III Coupe adaptable for both sporty and practical usage.

The Porsche Cayenne III Coupe features a ride height (ground clearance) ranging from 164 mm to 210 mm (6.5 to 8.3 inches), depending on suspension settings and model variant. This adjustable ground clearance allows the vehicle to tackle light off-road terrain and uneven surfaces with ease, while still maintaining excellent on-road stability. The adaptive air suspension option available on some variants lets drivers increase ride height when driving off-road or on rough terrain, improving approach, breakover, and departure angles, thus enhancing the SUV's versatility.

When considering garage fitment, the Porsche Cayenne III Coupe's width including mirrors is 2194 mm (86.3 inches), and height ranges between 1636 mm to 1676 mm (64.4 to 66 inches). Standard single-car garages typically have widths around 2438 mm (96 inches) and heights of about 2134 mm (84 inches), so the Cayenne III Coupe should fit comfortably within these dimensions. However, the width with mirrors requires careful mirror folding for ease of entry and exit in narrower garages. Its coupe roofline and height also make it manageable for typical residential garages.

The Porsche Cayenne III Coupe can come fitted with a variety of rim sizes including 20-inch, 21-inch, and 22-inch wheels (rim widths ranging approx. 9.0J to 11.5J), paired with matching tires sized from 275/45 ZR20 to 315/30 ZR22. Larger wheels with lower-profile tires generally improve cornering grip and sporty handling but can slightly reduce ride comfort due to stiffer sidewalls. Smaller wheels with higher-profile tires offer a cushier ride ideal for daily and long-distance comfort. Porsche balances performance and comfort options with adaptive suspension technology to optimize the driving experience based on tire and rim choices.

Compared to the second-generation Cayenne Coupe (Cayenne II Coupe), the third generation Cayenne III Coupe shows modest increases in size and weight. While exact predecessor measurements varied, the Cayenne III Coupe is slightly longer (approx. 4931-4942 mm vs. roughly 4800-4900 mm in the predecessor), wider by about 30-40 mm, and somewhat taller depending on suspension settings. These changes enhance interior space and cargo capacity. Performance-wise, the Cayenne III Coupe benefits from updated powertrains, advanced suspension systems, and better chassis rigidity, resulting in sharper handling and improved fuel efficiency compared to its predecessor.

Within the luxury coupe SUV segment, the Porsche Cayenne III Coupe holds a competitive size profile. For instance, it is slightly longer and wider than competitors such as the BMW X6 and Mercedes-Benz GLE Coupe, providing a balance between interior space and sporty proportions. Its cargo volume, ranging up to 1540 liters (54.4 cubic feet) with seats folded, is comparable or superior to many rivals, offering practicality alongside performance. The Cayenne's ride height and ground clearance also provide versatility beyond many competitors who may emphasize either sportiness or rugged capability but not both.

The Porsche Cayenne III Coupe has a maximum roof load capacity of 75 kg (approximately 165 pounds). This means the roof can safely accommodate roof racks, carriers, or luggage boxes designed for this weight limit without compromising structural integrity or handling. When fitting roof-mounted accessories, it is important to ensure the total weight, including any items carried, does not exceed this limit to maintain vehicle stability, aerodynamics, and safety. Porsche also recommends professional installation of roof accessories and checking compatibility with the coupe's distinct roofline.

The Porsche Cayenne III Coupe, produced from 2019 to 2023, is available primarily as a sporty SUV coupe. Unlike the standard Porsche Cayenne SUV, the Coupe version features a more sloping roofline that imparts a dynamic aesthetic with slightly reduced rear headroom but improved sporty styling. This design is targeted at customers seeking a blend of SUV practicality with coupe-like visual appeal and driving dynamics. Despite this body style difference, the Cayenne III Coupe shares many underlying components with the standard Cayenne including engines, chassis technology, and interior features.
