Mclaren 720S Spider
The 720S Spider was introduced in December 2018 as the brand's new open top flagship sports car. Due to the integral roll structure of the monocoque used in the 720S, the Spider did not need additional bracing to compensate for the loss of a fixed roof. The modified monocoque loses the spine running from front to the rear of the car and is dubbed the Monocage II-S. Due to the loss of the roof, the 720S Spider uses traditional dihedral doors. The Spider weighs 45 kg (100 lb) more than its coupé counterpart due to the retractable hardtop system. The Spider marks the debut of new 10-spoke alloy wheels and new exterior colour options.
The roof is a single piece of carbon fibre and takes 11 seconds for operation, 6 seconds quicker than the 650S Spider. The roof can be operated at speeds up to 50 km/h (31 mph). The Spider uses the "flying buttress" as used on all convertible McLaren models. There is an added window on the buttress of the car to increase rear visibility. The retractable window between the roll-over hoops is carried over from the 650S Spider.
The engine and the transmission remain the same as the coupé with the engine generating the same amount of power. The Spider can accelerate to 97 km/h (60 mph) from a standstill in 2.9 seconds, to 193 km/h (120 mph) in 7.9 seconds and on to a top speed of 341 km/h (212 mph) with the top closed.
The 720S features McLaren's new M840T engine which is an evolution of the M838T used in the 650S. It is a 3,994 cc (4.0 L; 243.7 cu in) twin-turbocharged V8 engine. However, the stroke has been lengthened by 3.6 mm to increase the capacity and 41% of the engine's components are new. The engine uses new twin-scroll turbochargers which have a low inertia titanium-aluminium turbines which spin with maximum efficiency with the help of actively controlled waste gates. The engine has a rated power output of 720 PS (530 kW; 710 hp) at 7,000 rpm, giving the car its name; the maximum torque is 568 lb⋅ft (770 N⋅m) at 5,500 rpm.
