The McLaren Senna is a limited-production mid-engined supercar and the third addition to the McLaren Ultimate Series, joining the F1 and the P1. Limited to 500 hand-built units, the Senna was unveiled online on 10 December 2017, with the official reveal taking place at the 2018 Geneva Motor Show.

Named after the Brazilian Formula One racing driver Ayrton Senna, the car pays tribute to his three Formula One World Drivers' Championship titles and thirty-five Formula One Grand Prix race wins. McLaren also won four consecutive Formula One World Constructors Championship titles with Senna as part of their driver line-up. 

The Senna is largely based on the McLaren 720S, using a modified version of its carbon fibre monocoque chassis, named MonoCage III. It is powered by an uprated version of the McLaren 720S' 4.0-litre twin-turbocharged V8, codenamed the ‘M840TR’, paired with a seven-speed dual-clutch transmission that delivers 789 hp and 590 lb ft of torque to the rear wheels. The result is a 0-62mph sprint time of just 2.8 seconds, and a blistering top speed of 208mph. 

Aerodynamic features include a large electrically adjustable rear wing which doubles as an air brake, along with a double-element diffuser, a Formula One-inspired roof scoop, front and side air intakes, rear air louvres, and large front fenders. Stopping power is from Brembo carbon ceramic brakes, housed within lightweight centre-lock alloy wheels designed for Pirelli P-Zero Trofeo R tyres. The car utilises a top-mounted inconel-titanium exhaust system with three outlet pipes, as well as McLaren's hydraulic RaceActive Chassis Control II (RCC II) suspension with double-wishbone control arms.

Inside, the cabin consists largely of exposed carbon fibre and Alcantara, and behind the two seats is room large enough for two helmets and race suits, reflecting the car's track-focused design.
