The Nerve Hammer is a Hot Wheels Original Design. Designer Jun Imai named it Nerve Hammer after a phrase Nathan Proch used to say often. Nerve Hammer has a carbon fiber exoskeleton structure on coilovers and aluminum chassis. Three fixed variants of Nerve Hammer (as well as a customizable version) are playable in Hot Wheels: Track Attack In 2013, the casting changed with a slightly different body design and an 'integrated' rear spoiler. The rear spoiler on all prior versions is a separate plastic piece.
