About as mad as a factory Viper gets, the SRT10 ACR (American Club Racer) is a light weight be-winged version of the already ludicrous 2008 600hp V10 Viper.

Lots of plastic and the usual dodgy (pardon the pun) interior that comes with Vipers but who cares - its the wild looks and that V10 that define the Viper. Until the Nissan GT-R arrives in North America there isn’t much south of $US100k that can kick sand in the Vipers face.
