As with the MP4-12C Spider with which it shares a platform, the 650S Spider features a retractable hardtop that effectively makes it a coupe with the roof fitted. The roof takes 17 seconds to raise, a task that can be accomplished at speeds up to 19 mph.
McLaren says the car's carbon fiber MonoCell chassis did not require any additional strengthening, despite the removal of the roof. The weight penalty over the coupe is about 88 pounds. The 650S Spider comes equipped with the coupe's lightweight alloy wheels, Pirelli P Zero Corsa tires, and carbon ceramic brakes.
Also unchanged is the 12C-derived 3.8-liter twin-turbocharged V-8, which produces the same 641 horsepower and 500 pound-feet of torque it does in the 650S hardtop. That allows the 650S Spider to do 0-62 mph in 3.0 seconds, 0-124 mph in 8.6 seconds, and reach a top speed of 204 mph.
That's 0.1 second, 0.2 second, and 3 mph behind the coupe, respectively. It doesn't look like convertible buyers will sacrifice much in the way of performance.
McLaren says the 650S Spider will also return the same 24.2mpg on the European combined cycle as the coupe. That number will be significantly lower in U.S. EPA testing, though.
There's also no shortage of convenience features in the Alcantara-trimmed cabin. The 650S Spider comes standard with Bluetooth, IRIS satellite navigation, SIRIUS satellite radio, and voice controls.
Sales begin later this year.
