More McLaren Senna Info Spills Forth: Here\'s What You Need To Know
It Has a Next-Level Suspension
Like the P1 before, the Senna relies on a hydro-pneumatic damper package that links the dampers both transversely and longitudinally. This system gave the P1 a docile demeanor on the street while maintaining razor-sharp precision on a track. When put in Race mode, the Senna drops its already low nose a further 1.2 inches and its rear by 0.9 inch. This rake improves the diffuser’s performance and offers little ground clearance. The front is so low that McLaren fitted a sacrificial section to the splitter that is easily swapped out using exposed fasteners.
The Rear Wing Is Top-Mounted
The so-called swan-neck mounts are ripped right from the world of racing. By keeping the bottom edge of the airfoil free of mounting pylons, the wing’s business edge can maximize its ability to push the Senna onto tarmac. Under braking, the wing snaps upright to act as an air brake. The rear wing weighs just 11 pounds.
It Uses Aero Tech Outlawed by Formula 1
Formula 1 banned double diffusers for the 2011 race season, but that doesn’t mean McLaren can’t put them on road cars. Diffusers can generate as much or more downforce as wings. As are most such pieces on high-end supercars, the diffuser is made of lightweight, strong, and stiff carbon-fiber-reinforced plastic. Of course, so is most of the rest of the car. From the central tub, to the one-pound front fenders, to the seven-pound seats, it’s all carbon fiber. McLaren has put all its chips on the black weave, so much that it just christened a new carbon-fiber factory in Sheffield, England. While the Senna’s tubs will come from Austrian supplier Carbo Tech, the three-seat BP23 tubs will serve as Sheffield’s pilot build. After the 106 planned BP23 tubs are off the assembly line, we suspect the tubs for McLaren’s next-gen Sport Series (the part of the lineup that currently includes the 570S and 570GT) models will be the next batch to bake in Sheffield’s autoclaves.
