The McLaren 720S is a British sports car designed and manufactured by 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 in contrast to the 650S.

Specifications

Engine

The 720S features McLaren's new M840T engine.^[5] It is a {{convert|3994|cc|L CID|1|abbr=on}} twin-turbocharged V8 engine, essentially a rework of McLaren's previous 3.8-litre engine. However, the stroke has been lengthened by 3.6 mm to increase the capacity and 41% of the engine's components are new.^[6] The engine produces {{convert|720|PS|bhp kW|0|abbr=on}} at 7,000 rpm, giving the car its name; the maximum torque is {{convert|568|lbft|Nm|0|abbr=on}} at 5,500 rpm.^[7]

Performance

According to McLaren the 720S can accelerate from {{convert|0-62|mph|km/h|abbr=on|0}} in 2.9 seconds, {{cvt|0-124|mph|kph|0|abbr=on}} in 7.8 seconds, can achieve a maximum speed of {{convert|212|mi/h|km/h|abbr=on|0}},^[7] and has a {{convert|1/4|mi|m|0}} time of 10.3 seconds.^[8] The 720S's handling is improved with McLaren's Proactive Chassis Control II, which used findings from a PhD course at the University of Cambridge.^[5] The 720S also comes with Variable Drift Mode, which manipulates the stability control to help drift the car.^[9]

The McLaren 720S has a power to dry weight ratio of {{convert|{{#expr:1283/720 round 2}}|kg|lb|2|abbr=on}} per horsepower, which is better than the McLaren 675LT ({{convert|{{#expr:1230/675 round 2}}|kg|lb|2|abbr=on}} per horsepower), and the Ferrari F12tdf ({{convert|{{#expr:1415/780 round 2}}|kg|lb|2|abbr=on}} per horsepower).

Efficiency

McLaren claims class-leading efficiency for the new 720S, with CO₂ emissions of 249 g/km and combined fuel economy of {{convert|26.4|mpgimp|mpgus|1|abbr=on}}^[10]—both of these figures represent an improvement of around 10% from the 650S.

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.^[11] The doors feature air channels that direct air to the engine.^[12] The rear of the car features thin LED tail-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.^[5] All of the exterior features result in an improvement of 50% more downforce than the 650S.^[11] The interior of the car includes a folding driver display and carbon fibre accents.^[12] {{citation needed span|The McLaren 720S weighs just {{convert|1283|kg|lb|0|abbr=on}} dry, making it the lightest in its class.|date=July 2018}}

Variants

720S Velocity

Mclaren Special Operations unveiled the McLaren 720S Velocity just one day after the 720S was revealed.^[13] It featured Nerello Red and Volcano Red paint scheme, and a carbon fibre bonnet.^[13] In addition to those, the wheels are lightweight aluminium painted metallic bronze. The interior has Carbon Black Alcantara trim with red highlights, and carbon fibre accents.^[13][14]

720S GT3

Unveiled at the 2018 Pebble Beach Concours d'Elegance, the 720S GT3 marks the beginning of McLaren's outreach to both amateur and professional racing drivers. The car is claimed to have been changed by 90% when compared to the road legal version. The main highlights include the M840T twin-turbocharged V8 engine tuned to race specifications; mated to a 6-speed sequential manual transmission instead of the dual clutch unit found on the road car, a newly developed roll cage, a fixed carbon-kevlar racing seat, a six-point racing harness, a roof-hatch extraction system, along with side-impact foam, all complying to the latest FIA GT3 regulations. The exterior is extensively modified as well and now includes a large fixed rear wing, bigger ram air-intake at the front, different head light clusters and a large rear diffuser. All of the aerodynamic elements have been thoroughly tested and calibrated for maximum efficiency by using Computational Fluid Dynamics (CFD) which saves the research and development costs of making a full-scale mock-up and testing it.

McLaren's main aim with the 720S GT3 was to allow easy accessibility of the car to drivers and teams, not just on driving standpoint, but on serviceability and financial viability as well. Keeping that into consideration, efforts have been made to keep the car as fuel efficient as possible while working with the tyre supplier, Pirelli to allow the car to be able to last endurance races with ease.

The 720S GT3 would be available for the general public and racing teams at the start of the 2019 season of the FIA GT3 Championship.^[15]

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 {{cvt|100|lb|kg|0|abbr=on|order=flip}} 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 {{cvt|31|mph|kph|0|abbr=on|order=flip}}. 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 {{cvt|97|kph|mph|0|abbr=on}} from a standstill in 2.9 seconds, to {{cvt|120|mph|kph|0|abbr=on|order=flip}} in 7.9 seconds and on to a top speed of {{cvt|212|mph|kph|0|abbr=on|order=flip}} with the top closed. The top speed reduces by {{cvt|10|mph|kph|0|abbr=on|order=flip}} with the top retracted.^[16][17]
