No disrespect to Jaysen, but I don't think Ragan's Busch Series Fusion can quite lay claim to being The World's Fastest. Last I checked, it would do around 180 MPH. The real honor goes to the Fusion shown below, which set a new speed record of over 207 MPH at Bonneville in July. And it used a Hydrogen Fuel Cell for power! Even more remarkable is that it clearly has stock sheetmetal with opening doors, real glass, etc, vs. the "one-body-fits-all with decals" that NASCAR serves up these days. It appears the grille and headlamps were filled in, the rear spoiler added, and the car lowered, but otherwise it looks pretty stock! Big kudos to the team from Ford, Roush, Ballard, and Ohio State, plus Ford retiree and driver Rick Byrnes for setting the new Fuel Cell speed record with this Fusion!
