If you can't afford a Demon or a Hellcat, the Scat Pack is a suitably performant variant of the Charger or the Challenger. They all share the same V8 engine, which can output 485hp, with peak power at 6,100RPM. And, another 475 lb-ft of torque, with peak torque at 4,100RPM. In its earliest model years, the Charger and Challenger Scat Pack cars had around 432hp. The 392 Scat Pack trim was then upgraded over the years, raising the horsepower to 470hp. And as of late, 485hp. This accompanied a newer transmission, too. The earlier Scat Pack cars came with a Mercedes-sourced 5-speed automatic, while the later ones had an 8-speed automatic, with paddle shifters on the steering wheel.
