1817-HP Hennessey Venom F5 Roadster is a 300 MPH+ Roofless Wonder

Hennessey chopping the roof off its Venom F5 has increased the desirability quotient of this hypercar several times over. The Venom F5 Roadster continues to have the 6.6-liter twin-turbocharged V-8 mustering up a ludicrous 1817 horsepower along with a top speed of more than 300 mph. A carbon-fibre Targa panel weighing only 40 pounds also keeps the lightness in check and it is a simple one-person job to attach or remove. Only 30 of these low-flying UFOs will be built at $3 million each.
