Design The Senna has a resolute aspiration: to be the preeminent McLaren track-intense car for the road. This translates directly with its aggressive persona; deep lines, assertive arches and powerful spoiler. Every curve and grove created with one singular focus; aerodynamics. The tyres completely re-imagined to allow for nine symmetrical spokes instead of ten, surrounded by bespoke Pirelli P Zeroes all with the aim to cut additional weight.

Within the interior the Senna has been stripped of anything weight producing; with even the stereo being optional, ensuring every owner has the option of making this model as efficient as possible. McLaren provides choices of either leather or Alcantara to cover the deep racing seats that envelope and grip you around even the deepest of chicanes. The Senna leaves all other surfaces exposed in order to reduce weight and show off the carbon fibre that forms the foundation of the chassis.
Performance The Senna is sure to put you in pole position whilst delivering the most intense driving experience around the circuit. As a result of its carbon fibre chassis and body parts the Senna is the lightest vehicle McLaren have built since the iconic F1. With its RaceActive Chassis Control II (RCC II) hydraulic suspension and the ultra-rigid MonoCage III monocoque and staggering power-to-weight ratio the McLaren Senna is utterly dedicated to supporting the driver to be the best they can possibly be.

The Senna comes fitted with a 4.0-litre twin- turbocharged V8 engine, resulting in increased performance and a new track benchmark for McLaren. The Senna adorns McLaren’s first centre-locking lightweight wheels and a new generation of carbon ceramic brake discs (CCM-R). Four-times more thermally efficient than previous brakes, the CCM-R’s are smaller and therefore lighter adding to the theme of weight-saving measures.
Technology Within the cockpit the centre-mounted infotainment system includes a seven-speaker audio system as standard. Providing audio and navigation functions with touch-sensitive buttons on the steering column resulting in all controls being available at the swipe of the drivers fingers. The infotainment controls can also be handed over to the commands of a smartphone with capabilities of running both Apple CarPlay and Android Auto.
Reviews “Confidence is everything in road-legal cars capable of race-car performance. So many offer the outright grip and speed without making it accessible. The Senna is different. No other road-legal track-day car has such a fully realised blend of mind-blowing circuit performance and excitement, amazingly tame drivability and brain-frazzling driver reward.”
