#2 The Dodge Challenger SRT8 ACR

The Dodge Viper SRT10 ACR is arguably the best performing supercar in the world, with a variety of track records including famous tracks like Laguna Seca and the Nürburgring.  At the 2011 SEMA Show, Mopar brought out the powerful Dodge Challenger SRT8 with a spread of modifications similar to what differentiates the standard Viper SRT10 from the ACR model – and the Challenger SRT8 ACR is born.  This Challenger features a high performance braking and suspension package, a variety of weight reduction items and an exterior design theme that pays homage to the Viper ACR.  Unfortunately, this is only a “design study” so it may not see production…although it would certainly complicate the battle for the super muscle car title currently being fought between the Camaro ZL1 and the Shelby Mustang GT500.
