Hand-built and limited to 500 units worldwide, the new McLaren Senna embodies the spirit of the legendary Brazilian driver. This Ultimate Series model remains street-legal, but is first and foremost a track car. Consider the ultra-light weight, the next-generation active aerodynamic components, the evolution of the carbon fibre chassis from the 720S, the twin-turbocharged V8 unleashing 789 horsepower to the rear wheels and the race-derived adaptive suspension.
