Surprised this hasn't been posted yet. Due to premier at SEMA, this is the concept for the 2015 Viper ACR, damn hot! For the record, I believe that this concept has the standard hp 8.4 V10 in it, hopefully the production version gets something with a little more bite. "This yearâs SEMA show is just a couple of weeks away but weâve been given an early look at whatâs destined to be one of the stars of the upcoming tuning fest. Revealed today is the Dodge Viper ACR Concept, which unashamedly previews the ultimate track-focused but street legal version of the fifth-generation model. The last Dodge Viper ACR (for American Club Racing) rolled off the assembly line in 2010, boasting a stock engine but weight savings of around 90 pounds and an aero package that could produce upwards of 1,200 lbs of downforce. It also turned a lap time of 7:12.13 on Germanyâs fabled NÃ¼rburgring circuit in 2011, a production car record at the time. Dodge is yet to confirm a new Viper ACR for production but the thinly-veiled concept hints strongly at its imminent arrival. The vehicle features an aggressive carbon fiber splitter and a set of dive planes up front, and these work in conjunction with a competition rear wing to maximize downforce. Also new are the front fender vents and satin black 19-inch light alloy wheels. Another vital upgrade is the massive 15.4-inch carbon ceramic rotors, clamped by Brembo six-piston calipers. These are kept cool by carbon fiber brake duct openings in the front fascia, while additional cooler ducts rearward of the side windows supply fresh cool air to the limited-slip differential for optimal performance. Inside is a race-inspired design that puts an emphasis on weight reduction. Only the bare necessities remain as radio amplifier, speakers, carpet and NVH treatments have been removed to take advantage of every ounce. Much of what remains has also been swapped out for lighter carbon fiber pieces, and many of the surfaces have been trimmed in Alcantara. Of course, there will be plenty of other Fiat Chrysler Automobiles [NYSE:FCAU] products present at SEMA. As previously reported, they will include a Poison Dart R/T Concept, Challenger T/A Concept, Fiat 500 Abarth Scorpion, Chrysler 200S Mopar Concept, Dodge Charger Mopar Concept, Fiat 500L Custom, Jeep Renegade Trailhawk Frostbite, Renegade Limited Rip Tide, Ram ProMaster, and Ram 2500 Outdoorsman. http://www.motorauthority.com/news/1095111_dodge-viper-acr-concept-headlines-mopars-2014-sema-fleet "
