A man like Saleen , will first tune the engine, so he did. The standard SMS Challenger gets 500hp in the 570 model, but add a turbo or a super charger, and it jumps up to 700hp in the 570X model. And this amazing power connected to a 6-speed TREMEC manual gearbox, so it could hit 60 mph in under 4 seconds. And if there's enough space, it'll be going all the way to 200 mph!
Moving on to the exterior part, including: re-designed grill, 20-inch rims, re-designed brake-lights, new front & rear bumpers and finally aero-dynamic front & rear splitters. As a result, this tuned Challenger looks brutal. That's fantastic for a muscle car.
As for the price, it starts from $50,000, with the added power, it rockets to $70,000. That's a lot for a Challenger, and they're a lot of competitors out their. But none, with this price, has 700hp.
