In the World Human-Driven Speed Competition, vehicle designer and manufacturer Aerovelo broke its own record for the fastest human-powered vehicle in the world, reaching 40.05 m/s (144.18 km/h).
They use an egg-shaped bicycle called the Eta. Not only does the car weigh only 55 pounds, but its carbon fiber shell reduces air resistance a hundred times better than a normal car. The frame is constructed of wet-laid carbon fiber, and the shell is made of a material sandwiched between an aramid honeycomb core and carbon fiber.
Aerovelo claims an analysis of vehicle behavior shows that the Eta requires only 198 watts of energy to pedal at 90 mph, which translates to 9,544 mpg. That’s the highest mpg per passenger of any existing transportation technology at that speed.
Cameron Robertson, co-founder of Aerovelo, said: “The efficiency of this car seems to be incredibly high. This is strong evidence that we can achieve it in the near future using existing technology and reducing weight. Also, Eta rides very smoothly.”
