Sometimes the best motivation is inspired by those who say "it is not possible". Engineers told General Chuck Yeager that airplanes would explode if they broke the sound barrier. Condescending male journalists told Nellie Bly she couldn't go "Around the World in 80 Days". So she did it in 72. In an ever-escalating war of top speed, the automotive industry seems to think 300 miles per hour is not achievable with current technologies. Perhaps this is why Hennessey Performance uploaded an image of the upcoming Venom F5 next to a speed limit sign. Just like the people who told him the Venom GT wouldn't go 270 mph, it seems John Hennessey is looking to silence other top speed rumors coming from France.
