2017 McLaren 720S Dimensions, Size & Specs

The McLaren 720S' width varies depending on the position of the side mirrors. With the mirrors folded, the width is 2059 mm (81.06 inches), while fully opened mirrors increase the width to 2161 mm (85.04 inches). This adjustment is important for parking or maneuvering through tight spaces, as folding the mirrors reduces the overall width, helping the car fit into narrower gaps or garages. Drivers should be aware of this when estimating space requirements, as the opened mirrors add an additional 102 mm (4 inches) to the car's width.

The McLaren 720S has a curb weight of 1419 kg (3130 lbs), which is relatively light considering its power and size. This lightweight is achieved through extensive use of carbon fiber in its MonoCage II chassis and other aluminum components. The low weight contributes significantly to the 720S's remarkable acceleration, handling, and overall agility. Less weight means improved braking, faster cornering, and enhanced fuel efficiency compared to heavier supercars, making it one of the quicker and more responsive cars in its class.

The McLaren 720S offers a luggage capacity of 360 liters (12.7 cubic feet), which is quite generous for a high-performance supercar. This storage is split between the front trunk (frunk) and additional compartments, allowing for some flexibility with bags or small luggage. While not designed for carrying large amounts of cargo, this capacity makes the 720S more practical for occasional trips or weekend use compared to many other supercars, which often have very limited storage space. However, it remains primarily a driver-focused machine, so everyday convenience is balanced against performance priorities.

Yes, the McLaren 720S generally fits into a standard home garage. Standard single-car garages are typically about 2440 mm (8 feet) wide and 6100 mm (20 feet) long, which provides sufficient space for the 720S's 4543 mm (178.7 inches) length and 1930 mm (75.98 inches) width, especially when the side mirrors are folded (2059 mm or 81.06 inches). The car's height is low at 1196 mm (47.09 inches), so vertical clearance is rarely an issue. However, drivers should consider the opened mirror width of 2161 mm (85.04 inches) and confirm garage door width to avoid any tight squeezes.

Compared to its predecessor, the McLaren 650S, the 720S shows some evolved dimensions and reduced weight. Although the exact dimensions of the 650S are approximately 4512 mm in length, 1946 mm in width, and 1190 mm in height, the 720S is slightly longer by 31 mm (1.22 inches) but marginally narrower without mirrors by 16 mm (0.63 inches). The curb weight is significantly lighter in the 720S at 1419 kg (3130 lbs), approximately 100 kg less than the 650S, thanks to a new carbon fiber MonoCage II chassis. This weight reduction improves acceleration, handling, and overall performance, representing a considerable advancement over the 650S.

The McLaren 720S competes with supercars like the Ferrari 488 GTB and Lamborghini Huracán. Dimensionally, the 720S is comparable but often slightly lighter and lower in height. For example, the Ferrari 488 GTB is about 4566 mm long and weighs around 1475 kg, making the 720S a bit more compact and lighter. The 720S’s swift acceleration and aerodynamic design give it a competitive edge in performance, while its advanced carbon fiber chassis contributes to superior weight savings. Overall, the 720S’s balance of size, lightness, and engineering innovation places it at the forefront of its category.

The McLaren 720S is equipped with Michelin Pilot Sport Cup 2 tires, sized 245/35 R19 at the front and 305/30 R20 at the rear. These tires run on rims sized 9.0 J x 19 for the front and 11.0 J x 20 for the rear. The staggered setup—narrower front and wider rear tires—optimizes grip and handling by improving traction and cornering balance. This enhances performance during high-speed driving or tight turns. The tire choice and rim dimensions complement the car’s aerodynamics and suspension system to deliver exceptional stability and responsiveness in various driving conditions.

The McLaren 720S features a striking aerodynamic design with sculpted bodywork that improves airflow and downforce. Its low height of 1196 mm (47.09 inches) minimizes frontal area to reduce drag. The active rear spoiler and dihedral doors enhance aerodynamics while maintaining a compact footprint. The car's width, including mirrors, balances road presence and efficiency, and its carbon fiber clamshell hood serves as an aerodynamic element as well. These design elements collectively optimize the car’s performance by reducing drag coefficient and increasing stability at high speeds without excessively increasing size.

Despite the McLaren 720S’s relatively compact exterior dimensions, the cabin is designed to maximize driver and passenger comfort. The seating position is low to improve handling feedback and aerodynamics, with ergonomic controls arranged around the driver. Although interior space is tight compared to regular cars due to its supercar form factor and low roofline, the cockpit offers sufficient legroom and headroom for average-sized adults. The 720S also features modern materials and technology ensuring a luxurious experience, balancing its performance-oriented design with usability for spirited drives or occasional longer trips.
