At full tilt, this incredible machine sounds like a fighter jet.
Every year, a section of Idaho’s Highway 75 is used to host the Sun Valley Road Rally. Essentially, the event allows participants to drive as fast as they like on a public road. Of course, they have to pay for the privilege, but proceeds go to The Drug Coalition, a charity organization that raises awareness of substance abuse, addiction and recovery. Arguably the star of this year’s show was a one-off Bugatti Veyron Grand Sport Vitesse L’Or Rouge dubbed the "Hellbug."
The droptop hypercar clocked a speed of 235.7 mph while creating a sound more akin to a fighter jet than a road car. That’s what happens when you push a 1,200-hp 8.0-liter quad-turbocharger W16 powerplant to the max.
