The McLaren Senna is the personification of McLaren’s DNA at its most extreme, creating the purest connection between car and driver. It is the most track-focused road car we have ever built, and it will set the fastest lap times of any McLaren to date. That is what has driven us to build a track car that is unashamedly without compromise. One that is legalised for road use, but not sanitised to suit it. Nothing else matters but to deliver the most intense driving experience around a circuit.
Inspired by one of McLaren’s greatest racing drivers, the McLaren Senna is utterly dedicated to allowing the driver to be the best they can possibly be.
The McLaren Senna has a single-minded purpose. In the pursuit of the most rewarding and intuitive driving experience, pioneering active aerodynamics generate unprecedented levels of downforce. It is also the lightest vehicle we have built since the iconic F1, with our most powerful road car engine to date. This combination creates a staggering power-to-weight ratio of 668PS-per-tonne (659bhp). It is the most direct and responsive McLaren ever built, surpassing even the McLaren P1™ GTR, to create the purest connection with the driver. The McLaren Senna is a new track benchmark for McLaren.
The McLaren Senna is the ultimate distillation of the company’s ‘form follows function’ design mantra. To observe the detailed work that has gone into every aerodynamic element of the McLaren Senna is mesmerising. To experience it all working in unison is truly incredible. The resulting 800kg of downforce in Race mode at significantly less than maximum speed (155mph or 250km/h) is phenomenal, and the McLaren Senna creates, maintains and controls its aerodynamic performance to ensure the driver has the confidence to explore the limits such downforce unlocks.
We think of the McLaren Senna as a race car – we have designed and built it to perform on the track first and foremost. The active aerodynamics are pioneering, and the unprecedented visibility achieved through the unique glazed doors gives the driver total confidence. Exhaustive, fearless engineering has led us to revaluate and reassess every component, no matter how small or insignificant, to maximise performance. We have used carbon fibre for the monocoque, the body and everywhere we need lightness, rigidity and strength – it is the reason the McLaren Senna is the lightest road vehicle McLaren Automotive has ever built.
800PS and 800Nm from a 4.0-litre twin-turbocharged V8, the most powerful internal combustion engine McLaren has ever built. 800kg of downforce made possible by pioneering active aerodynamics. The lightest McLaren since the iconic F1 with dry weight of under 1200kg. A power-to-weight ratio of 668PS-per-tonne (659bhp) that ensures it will set the fastest lap times of any McLaren road car to date. 0-124mph (0-200km/h) in 6.8 seconds and a top speed of 208mph (335km/h). Next-generation carbon ceramic brakes that utilise racing technology. Discover the savage performance of the McLaren Senna.
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.
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.
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.
The exhaust system on the McLaren Senna is beautifully crafted in lightweight Inconel and titanium, and the ‘slash cut’ pipes exit through the rear deck. Tightly packaged and painstakingly engineered to reduce weight, they are not the simplest engineering solution but they are the most efficient and most effective. Exhaust upthrust from their specific angle contributes to the aerodynamic efficiency of the McLaren Senna and their unique position improves engine cooling. The intense crescendo encourages the driver to use high rpms, the volume increasing with 10dB for every 2,000rpm, climbing right through to the engine’s rev limit.
