The McLaren 720S is a sports car designed and manufactured by British automobile manufacturer McLaren Automotive. It is the second all-new car in the McLaren Super Series, replacing the 650S beginning in May 2017. The 720S was launched at the Geneva Motor Show on 7 March 2017 and is built on a modified carbon monocoque, which is lighter and stiffer than the previous model, the 650S.

Specifications

Engine

The new car features McLaren's new M840T engine. It is a 4.0-litre (3994 cc) twin-turbocharged V8 engine, essentially a rework of McLaren's previous 3.8-litre (3799 cc) 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 produces 720 PS (530 kW; 710 bhp) @ 7000 rpm, giving the car its name; the maximum torque is 770 N·m (568 lb·ft) @ 5500 rpm.

Performance

The McLaren 720S can go from 0-62 mph in 2.9 seconds (0.1 seconds faster than the 650S), and 0-124 mph in 7.8 seconds (0.6 seconds faster than the 650S). The top speed is 212 mph (341 km/h), and the car will complete the 1/4 mile in 10.3 seconds. The 720S' handling is improved with McLaren's Proactive Chassis Control II which was born from the findings of a five-year PhD course at the University of Cambridge. The 720S also comes with Variable Drift Mode, which manipulates the stability control to help drift the car.

McLaren 720S has a power to weight ratio of 1.78 kilograms (3.92 lb) per horsepower, better than the McLaren 675LT (1.82 kg (4.01 lb) per horsepower), and the Ferrari F12tdf (1.81 kg (3.99 lb) per horsepower).

Efficiency

McLaren claim class-leading efficiency for the new 720S, with CO₂ emissions of 249 g/km and combined fuel economy of 26.4 mpg - these both represent improvements of around 10% from the 650S. Can be different in some countries and year of the model.

Design

The McLaren 720S features twin-hinged dihedral doors and many design features from the McLaren F1. The headlights hide air vents that funnel incoming air to two small radiators in front of the wheels. The doors feature air channels which directs air to the engine. The rear of the car features thin LED lights similar to those on the McLaren P1, and two round exhaust pipes. The design was inspired by the great white shark, and features a teardrop-shaped cockpit. The 720S produces 50% more downforce than the 650S. The interior of the car includes a folding driver display and carbon fiber accents. The McLaren 720S weighs just 1,283 kg (2,829 lb) dry, making it the lightest in its class.

Most of the car, however, is based on the McLaren F1.

Variants

720S Spider (2018-Présent)

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 top speed reduces by 16 km/h (10 mph) with the top retracted.

765LT Spider (2021-)

Unveiled on the 27 July 2021, the convertible is a limited (765 units, 11 in Hong Kong) version of 765LT coupe. It uses the same M840T engine which produces 765 PS (563 kW; 755 hp). The Spider weighs 80 kg (176 lb) less than the 720S Spider at 1,388 kg (3,060 lb), making it 49 kg (108 lb) heavier than the coupe.

720S 'Velocity'

Mclaren Special Operations revealed the McLaren 720S Velocity just one day after the 720S was revealed. It has Nerello Red and Volcano Red paint, and a carbon fiber hood. In addition, the wheels are lightweight aluminum painted metallic bronze. The interior has Carbon Black Alcantara trim with red highlights, and carbon fiber accents. The 720S Velocity is priced at $407,750 (USD).

765LT Coupé

Unveiled on 3 March 2020, the 765LT is a limited (765 units, 12 in Hong Kong) version of the 720S and the successor to the 675LT as a Super Series Longtail car, focused on track performance. The M840T engine is now rated at 765 PS (563 kW; 755 hp) at 7,500 rpm and 590 lb⋅ft (800 N⋅m) of torque at 5,500 rpm achieved with a higher-capacity fuel pump, forged aluminium pistons and a three-layer head gasket from the Senna. The top speed is lowered from the 720S's 341 km/h (212 mph) to 330 km/h (205 mph) due to added drag created by the added high downforce parts, although the 765LT weighs 80 kg (176 lb) less than the 720S at 1,339 kg (2,952 lb) in its lightest configuration and has a quicker 0–100 km/h (0–62 mph) time of 2.8 seconds. It also can hit 0–200 km/h (0–124 mph) in 7.0 seconds and complete a quarter-mile dash in 9.9 seconds according to McLaren.

The Senna's brake callipers are also available as an extra-cost option; McLaren claims these have four times the thermal conductivity as conventional carbon ceramics, while Pirelli Trofeo R tyres are standard. Suspension changes involve a 5 mm (0.2 in) reduction in ride height and the use of lightweight main springs with secondary "helper" units as well as an upgraded Proactive Chassis Control system. The aerodynamics are redesigned to produce 25% more downforce than the 720S, featuring front fender vents, a larger front splitter and a longer active wing element at the rear at the cost of less noise insulation, thinner-gauge glass and stiffened engine mounts. The rear of the car also features a quad-exit full titanium exhaust to distinguish it from the 720S. Production was limited to 765 cars globally with customer deliveries in October 2020.

750S (2023–)

The McLaren 750S is the successor of the 720S and McLaren Automotive's final model that is solely powered by an internal combustion engine. Essentially a facelifted version of the 720S, it features redesigned front and rear ends and an increase in power to 750 PS (740 hp). The 750S is also 66 pounds lighter than the 720S. According to McLaren, about 30 percent of the parts have been updated compared to the 720S. Other mechanical changes include a redesigned converging center-exit exhaust system, larger air intakes, a shorter transmission final-drive ratio, and a quicker steering ratio. On the interior, a new 8-inch Apple CarPlay-enabled infotainment system was added.

720S GT3

The McLaren 720S GT3 is a motorsport version of the 720S designed to take part in GT3 races. The car was revealed in August 2018 with a price of $564,000 and McLaren said that 90% of the car was different from the road-legal 720S. It was originally teased through renderings in November 2017.

720S GT3X (2021-)

In March 2021, McLaren announced the 720S GT3X, a track-only car based on the 720S GT3 which isn't limited by the restrictions put in place by the FIA for GT3-class cars.

McLaren 720S GT3X wins 2021 Goodwood Festival hill climb , set the fastest time at the 2021 Goodwood Festival of Speed’s famous hill climb timed shootout final, sprinting up the hill in just 45.01 seconds.
