The McLaren 720S is a mid-engine supercar built around McLaren's carbon-fiber Monocage II structure and powered by a 4.0L twin-turbocharged M840T V8 producing 710 hp and 568 lb-ft of torque. Power is delivered through a 7-speed dual-clutch transmission and rear-wheel drive, with the chassis using hydraulic Proactive Chassis Control II suspension, carbon-ceramic brakes, and lightweight aluminum and composite components.

Its aerodynamic package includes integrated front channels, side air intakes, a double-skin rear wing, and an active rear spoiler, while the suspension system uses interconnected hydraulic dampers instead of conventional anti-roll bars. Combined with the lightweight carbon structure, high-output V8, and electronically controlled chassis systems, these features give the 720S the technical foundation of a serious modern supercar without relying on all-wheel drive.
