On 12/05/2012 Chrysler trademarked the ACRX name. While we all assumed it was only a matter of time before the Viper ACR was reborn on the new SRT Viper, the ACR-X one comes as a “tiny” bit of a surprise. The last ACR-X Vipers were basically ACR’s without any street equipment and weren’t street legal. They were marketed as being the best of the street legal Viper ACR combined with racing elements found on the Viper competition coupe. Back in 2010 they had 640 HP because of headers and low restriction exhaust, they had track tuned suspension and aerodynamics, racing seat, roll cage and fuel cell for racing use but mainly for use at the Viper cup racing series.
Even if a full-race Viper isn’t in the cards for you, the important part here will be what kinda horesepower the new ACR-X has, as it’ll be compounding on the 640 that the V10 already puts out.
