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 chassis, which is lighter and stiffer in contrast to the 650S.

The McLaren 720S is priced from £208,600 (~$254,000).^[3]

Specifications

Engine

The new car features McLaren's new M840T engine.^[4] It is a 4.0-litre (3994 cc) twin-turbo 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.^[5] 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.^[6]

Performance

The McLaren 720S can go from 0-62 mph in 2.9 seconds (0.1 seconds faster than the 650S and matches the time of the 675LT), and 0-124 mph in 7.8 seconds (0.6 seconds faster than the 650S, 0.1 seconds faster than the 675LT).^[7] The top speed is 220mph (360 km/h), and the car will complete the 1/4 mile in 10.3 seconds.^[5] 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.^[4] The 720S also comes with Variable Drift Mode, which manipulates the stability control to help drift the car.^[8]

McLaren 720S has a power to weight ratio of 1.78 kg (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.

Design

Rear view of the McLaren 720S

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.^[9] The doors feature air channels which directs air to the engine.^[10]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.^[4]The 720S produces 50% more downforce than the 650S.^[9]The interior of the car includes a folding driver display and carbon fiber accents.^[10]The McLaren 720S weighs just 1,283 kg (2,829 lb) dry, making it the lightest in its class.
