I'm just finishing up the artwork for the new 2016 Dodge Viper ACR and this thing is cool. While I'm usually not a fan of huge wings, the ACR pulls it off and with 645 hp I'm sure it can use the downforce. If you have a Dodge viper enthusiast in the family and you are looking to give a gift, we have just the thing! 

As always here are all the specs,
