The new Spider model from McLaren Automotive features something very unique that has never been seen before on their MP4-12C series: a retractable hard-top roof. To activate the new roof, you simply need to flick a switch on the center console and in 17 seconds the metal hard top will completely retract. What makes this special, however, is the fact that you can perform this action as long as the car is moving below 20 mph–something unheard of in the world of convertibles. Besides the eye-catching new roof, the car is nearly identical to the previous model. Under the hood, the Spider features a 616 horsepower, 3.8-liter twin-turbo V8 that will take you from 0-60 in just 3.1 seconds. If you feel like stepping on the gas pedal, this car is capable of reaching speeds of up to 204 mph!
