Even though it was announced in May last year, the SMS 570X Dodge Challenger has been unveiled over the last weekend. This Challenger has a SMS Red Butterfly induction hood, improved drivetrain, suspension, aerodynamics, new tires, wheels and interior. The car is based on the R/T platform and it’s equipped with a 5.7L Hemi engine with supercharger that delivers more than 700 HP. It’s price starts at $70,000 but customers could also choose the SMS 570 which is a bit slower for $60,000. These new models will start to be produced at the end of this month and each ride will be signed by Steve Saleen as a part of the Signature Series and will have unique badges and graphics.
