McLaren’s latest supercar, the Senna, has some incredible numbers for gearheads to fawn over.
It really shouldn’t come as any surprise, but McLaren makes some pretty darned fast cars. As part of their Ultimate Series, along with the legendary F1 and P1, the Senna is set to arrive and make a big splash in the supercar scene.
The Senna already looks undeniably gorgeous. It takes its chassis from the McLaren 720S, an already beautiful car in its own right, and then tweaks it ever so slightly to grip the roads for dear life. The Senna also shares the 720S’ powertrain but produces 78 more horses and 22 more lb-ft of torque from the mid-mounted 4.0-L twin-turbo V8. That’s 789 hp and 590 lb-ft of torque total.
What magic did McLaren perform to eke out the extra power? First, a new air intake, then a carbon fiber plenum, then some specially designed lightweight cams and pistons along with two high-flow fuel pumps, and finally new internal sensors allowing for higher temperatures and compression values (or basically as close to the bleeding edge of failure as the engine will allow).
More power is nice. Saving weight is even nicer. To do that, the entire carbon fiber body weighs only 133 pounds. The total weight of the car is 2641 lbs, for a power to weight ratio of 597.5 hp/ton (or 3.347 lb/hp, depending on how you like your numbers thrown at you).
Top speed: 211 mph. Zero to sixty is in 2.7 seconds. Quarter mile is nothing but rearview after 9.9 seconds.
With that speed, the car needs some serious tech keeping it from shooting off into space. To start, the Senna has the same brakes and suspension as the P1. It also learns the lesson of the previous supercar making downforce as much a friend as possible. The rear wing, front spoiler, and all the fancy nooks and crannies along the body generate a total downforce of 1764 pounds at 55 mph. That’s like having a medium size cow on the roof and is 40 percent more downforce than the P1 ever had, according to Motor Trend.
McLaren will officially debut the car in Geneva next month, but if you’re excited to buy one you’ll be sorely disappointed. The entire 500 production run is already bought and paid for at $1 million per car.
