The Ariel Atom is one wild ride, featuring a fully-exposed driving experience and an unreal power-to-weight ratio. While there is a V8-powered Atom available, many of the swift and agile Atoms are motivated by Honda's trusty K20A. And where there's a Honda engine, Mugen isn't far behind. To celebrate 10 years of the Atom, Mugen will work its magic on 10 examples of the tossable, exposed chassis car. The K20 pumps out 240 horses in mortal Atoms but the Mugen plant delivers 270hp, and the car gets white aluminum wheels, custom paint and the appropriate Mugen badging and serial number plaque. Sounds fun.- EG
