The McLaren Senna Brings the Race Track to the Road

Patrick Schäfer

The new McLaren Senna is the "ultimate McLaren track-concentrated car for the road" according to its maker. The road-legal sports car bears the name of legendary Formula 1 driver Ayrton Senna. 

The sports car boasts several superlatives: it is designed to be lightest, most powerful and presumably fastest McLaren to receive approval for road use so far. The carbon fibre Monocage III chassis is based on the 720S, with the Senna tipping the scales at only 1,198 kilograms in total. The car’s aggressive design, originating from the Ultimate Series, is completely geared for aerodynamics and cooling – be it the front aero blades, the gurney flaps or the carbon fibre double diffuser at the rear. The active double-element carbon fibre rear wing optimises the aerodynamics and can be used as an airbrake when braking. 

The carbon fibre doors opening to the front and top are reminiscent of Formula 1. The striking two-piece glass side windows are designed to give the driver a better view of the road. The two-seater’s spartan interior is geared entirely towards the driver. The narrow McLaren Folding Driver Display provides information and is located behind the three-spoke steering wheel, while the upright infotainment screen is centrally positioned. 

Codenamed M840TR, the Senna’s 4.0-litre turbocharged V8 engine delivers 588 kW(800 hp) and maximum torque of 800 newton metres, making it the most powerful road-legal sports car McLaren has ever created. The seven-speed dual-clutch transmission provides rear-wheel drive. The driver can select from three modes: Comfort, Sport and Track. The RaceActive Chassis Control II (RCC II) hydraulic suspension is continuously adjustable. The adaptive dampers are interconnected hydraulically, with two valves per damper to independently adjust for compression and rebound. The brakes are equipped with carbon ceramic discs. More technical data will be available when the sports car debuts at the Geneva Motor Show in 2018.
