2019 McLaren 720S Spider Dimensions, Size & Specs

With a width of 2161 mm or about 85.0 inches when the mirrors are opened, the McLaren 720S Spider is wider than the average sedan, which typically range between 1800-1900 mm. This wider stance improves stability and handling at high speeds, but it requires extra caution in narrow streets or tight parking spots. Drivers should be mindful of the mirror width when navigating tight spots, as mirrors add critical but extended width, potentially making certain narrow lanes or parking garages challenging to maneuver without skillful driving.

The curb weight of the McLaren 720S Spider stands at 1468 kg (approximately 3235 lbs). This relatively light weight is a result of McLaren's extensive use of carbon fiber and lightweight materials throughout the chassis and body. The low curb weight significantly impacts the car's performance by improving acceleration, braking, and cornering agility. This lightweight construction helps the 720S Spider deliver thrilling performance while maintaining structural rigidity and safety standards, giving it an excellent power-to-weight ratio.

The McLaren 720S Spider, with its length of 4544 mm (178.9 in), width of 2161 mm (85.0 in) with mirrors opened, and height of 1194 mm (46.9 in), can fit into a typical North American or European residential garage. Standard garage dimensions generally accommodate vehicles up to around 2.44 meters (8 feet) in width and 5.5 meters (18 feet) in length, so the 720S fits comfortably in length and height. However, owners should consider the mirror width carefully, as standard garages may require folding or careful maneuvering to avoid mirror contact with garage walls or objects.

Compared to its predecessor, the McLaren 650S Spider, the 720S Spider is slightly larger and lighter despite offering more power and improved performance. The 720S Spider's length of 4544 mm (178.9 in) is marginally longer than the 650S Spider's approximately 4515 mm (177.8 in). Width with mirrors opened is wider on the 720S Spider at 2161 mm (85.0 in) compared to about 2012 mm (79.2 in) on the 650S Spider, enhancing aerodynamic stability. Importantly, the 720S Spider is significantly lighter, with a curb weight of 1468 kg (3235 lbs) compared to around 1534 kg (3383 lbs) for the 650S Spider, thanks to advanced carbon fiber construction. This results in a more agile and quicker vehicle overall.

In comparison with similar supercar roadsters, such as the Ferrari 488 Spider and Lamborghini Huracán Spyder, the McLaren 720S Spider is generally competitive in size but stands out with its lower height and lighter weight. The 720S Spider's length of 4544 mm (178.9 in) places it in the same ballpark as the Ferrari 488 Spider (approximately 4565 mm or 179.7 in) and slightly shorter than the Lamborghini Huracán Spyder (around 4524 mm or 178.1 in). Width with mirrors is wider on McLaren, aiding high-speed stability but requiring more spatial awareness. Height at 1194 mm (46.9 in) is lower than many competitors, contributing to its aerodynamic efficiency and aggressive stance. The curb weight at 1468 kg (3235 lbs) is notably lighter than many rivals, improving performance dynamics and efficiency.

The McLaren 720S Spider comes equipped with front rims sized at 9.0J x 19 inches and rear rims at 11.0J x 20 inches. The tire sizes are 245/35 R19 on the front and 305/30 R20 on the rear. These wide rims and low-profile tires provide substantial contact patches with the road, offering enhanced grip, cornering stability, and braking performance. The staggered sizing with wider rear tires improves traction for the powerful rear-wheel-drive setup, while the front tires balance steering precision and feedback. Such tire and rim setup contributes greatly to the 720S Spider's reputation for sharp handling and superb road manners.

Given the low exterior height of 1194 mm (46.9 inches), the McLaren 720S Spider offers a snug, sporty cockpit typical of high-performance supercars. While exact interior dimensions for height and width vary slightly, the cockpit is designed to maximize driver and passenger ergonomics without compromising aerodynamic styling. The width provides enough shoulder room for comfort, but the cabin remains focused on driver engagement rather than spaciousness. The low roofline enhances forward visibility and driving dynamics. Overall, the interior balances comfort and driver-centric design with the compact exterior size.

The McLaren 720S Spider benefits from a carefully engineered weight distribution, thanks mainly to its mid-engine layout and lightweight carbon fiber structure. The curb weight of 1468 kg (3235 lbs) is strategically spread to maintain near 42:58 front-to-rear balance, favoring the rear to optimize traction during acceleration and spirited driving. This balanced distribution enhances agility, cornering precision, and overall stability, providing a very confident driving experience. The lightweight chassis combined with ideal weight distribution plays an instrumental role in the car's superb handling capabilities.

While the McLaren 720S Spider is a high-performance roadster designed primarily for thrilling driving experiences, its dimensions and relatively light weight do make it more approachable than some bulkier supercars. The compact length of 4544 mm (178.9 in), combined with a low height of 1194 mm (46.9 in), aids agility in urban and suburban settings, although drivers should be mindful of the wide 2161 mm (85.0 in) mirror span in tight spaces. Its curb weight of 1468 kg (3235 lbs) supports dynamic driving without compromising fuel economy drastically. Despite its exotic nature, it can be used on a daily basis by enthusiasts who appreciate its blend of performance, practicality, and iconic McLaren styling.
