In order to optimize the RHT, the monocage II-S is characterized by the new design of the carbon fiber superstructure, to be installed as close as possible to air cooling outlets. This increases luggage space as much as possible, providing a storage capacity of 58 liters under the Tonneau cover when the roof of the car is closed. The Tonneau lid is also low compared to the 650S Spider-25mm, which widens the vision by 7.5 meters.

The acceleration capability is similar to that of a 720S Coupé and up to 220 mph when the roof is folded

The 720S Spider features an eight-cylinder engine with a 4.0-liter turbocharger, inspired by the Coupé. The engine is installed in the center of the weight of the vehicle to provide exceptional performance in terms of ease of control and response, and produces a capacity of 720 horsepower and 770 Newton meters of torque, and gives the car the lightest weight in class, gaining a rate of strength for the weight of 540 hp per ton, It is not surprising that this car reaches the highest levels of performance.

The high performance of the car applies to its acceleration ability, as the car can start from the stability position to a speed of 100 km per hour in 2.9 seconds only - a difference of 0.1 seconds from the speed of the Coupé. The car can also travel a quarter of a mile in 10.4 seconds - also less than 0.1 seconds from the Coupé.

When the conditions are right, the 720S Spider can emulate the Coupé version with maximum acceleration of 341 km / h (212 mph) in the closing position. Even when the roof is opened, the car maintains an exceptional top speed of 325 kilometers per hour (202 miles per hour). The slight differences between the 720S Spider and the 720 S Coupé are due to their aerodynamic performance and the 49 kg increase in the Spider.

The 720S Spider has the same striking appearance as the front and two-seater doors of the Coupé, two body parts, and plays a vital role in enhancing the aerodynamic and stability efficiency of the 720S. In addition, the front windshield and bonnet contribute, for example, to airflow control around the rest of the vehicle, while the air dynamics behind the front air stream are adjusted to match the new rear-section design and the full-featured active rear wing of the 720S Spider.
