Drive: 2015 McLaren 650s Spider Review - TractionLife.com (press release) (blog)

The 650S Spider weighs slightly more than the coupe variant, which is expected, as open cars always require additional reinforcement in other areas to preserve the structural rigidity that is lost by removing the fixed roof structure. It carries hints of the 12C as well as many cues from the company’s halo machine, the stunning P1. McLaren’s design team strives to maximize the aerodynamic efficiency of every product they create, so it should come as no surprise that the 650S is... A series of splitters, diffusers, panels, vents and spoilers direct the movement of air beneath the car to help cool various components, further induce downforce, or reduce turbulence. The lightweight alloy wheels are wrapped in ultra-sticky Pirelli P Zero Corsa tires that work hard to keep the car affixed to the pavement as you explore the outer limits of this car’s surgically precise handling which is further enhanced by more... The 650S is the first car to feature Brake Steer, a clever system developed by McLaren that subtly uses the rear brakes to manage traction, minimise mid-corner understeer and control oversteer when you corner at speed.
