The fastest lap times of any road-legal McLaren to date. The level of performance on offer from the McLaren Senna is self-evident from the numbers - 800PS. 800kg of downforce. A dry weight of under 1200kg. The fastest lap times of any road-legal McLaren to date. The figures only tell part of the story because, from the genesis of the McLaren Senna’s development, there has been an overwhelming drive to reflect the innate feel that Ayrton Senna experienced with his race cars. Without this, the blistering performance cannot be exploited. The McLaren Senna is the fastest McLaren road car ever around a racetrack, but these abilities go hand-in-hand with an intensely involving and immersive experience that puts the driver utterly in control.
The McLaren Senna combines the revolutionary suspension technology developed for the McLaren P1™ with our latest control theory to create RaceActive Chassis Control II. Offering truly uncompromising performance, this innovative new hydraulic suspension features a Race mode, which significantly reduces the ride height, lowering the centre of gravity and increasing the power of the aerodynamics. The level of sophistication in the McLaren Senna is groundbreaking. The hydraulic suspension allows relative compliance at low speeds in Race mode, aiding mechanical grip. Then, as speeds increase, it stiffens, supporting the increasing aerodynamic loads that would otherwise cause the vehicle to ground out on the circuit.
Our Most Powerful Engine Ever
The 4.0-litre twin-turbocharged V8 at the heart of the McLaren Senna is the most powerful McLaren road car engine ever, producing 800PS (789bhp) and 800Nm (590lb ft), with 700Nm (516lb ft) of torque available at just 3,000rpm. Designated M840TR, the powertrain features race-inspired dry sump lubrication and a flat-plane crankshaft, and lightweight connecting rods and pistons to reduce mass in the powertrain. The distinctive roof-mounted ‘snorkel’ feeds air directly into a bespoke carbon fibre plenum set atop the engine. This ultra-efficient air pathway, together with low-inertia twin-scroll turbochargers and electronic wastegates, delivers instantaneous throttle response.
Form Follows Function - To The Extreme
The extremely aggressive appearance of the McLaren Senna epitomises McLaren’s ‘form-follows-function’ design philosophy. Downforce and aerodynamic balance are the guiding principles and McLaren’s designers have gone to extremes, cutting open the shrink-wrapped body to reduce weight. Proportionally it is recognisably a McLaren, but you cannot follow a single line from the front to the rear without it passing through a functional intake or vent. In pursuit of absolute performance, the McLaren Senna is purposely fragmented in its appearance. For McLaren’s design team, it honours the engineering of the vehicle in the most honest way.
Intricate Aerodynamic Detailing
The rear clamshell of the McLaren Senna is born entirely from aerodynamic and cooling requirements. A prominent ‘gurney’ flap ahead of the stepped louvres repels air, directing it around the sides of the vehicle and driving it up towards the rear wing. The resulting area of low pressure draws hot air out from the high-temperature radiators and engine bay, with the succession of stepped louvres progressively linking airflow to the trailing edge of the vehicle and the towering carbon fibre rear wing. The carbon fibre intake plenum and 800PS (789bhp) powertrain are visible through a lightweight polycarbonate engine cover.
Innovative Suspension, Peerless Performance
The McLaren Senna combines all of McLaren’s knowledge to create the next generation of world-beating suspension: RaceActive Chassis Control II (RCC II). The cutting-edge suspension system has been designed to both generate and manage incredible aerodynamic loads, and create uncompromising track performance. RCC II allows the McLaren Senna to be driven on the road in relative comfort; however, select Race mode and the McLaren Senna can deliver a truly incredible lap time, with levels of downforce never seen before on a road car, and roll stiffness that is comparable to a GT3-specification race car. Quite simply, it is a ‘no compromise’ set-up.
A Body Built From Lightweight Carbon Fibre
The all-carbon fibre body is incredibly light and has the immense structural rigidity needed to support the aerodynamic forces it is subjected to at high speeds on a racetrack. At 150mph, and under huge aero loads, the front splitter of the McLaren Senna deflects less than 10mm. The rear wing assembly is equally impressive and the carbon fibre construction allows it to support more than 100 times its own weight in downforce. Both the roof-mounted ‘snorkel’ intake and the intake plenum atop the twin-turbo engine are constructed in carbon fibre, serving to lower the centre of gravity.
