Fiat Chrysler is getting back into the muscle car business — and in a big way. The company is launcing the 840-horsepower 2018 Dodge Challenger SRT Demon at a cool sticker price of $84,995.

The power plant is a supercharged 6.2-liter HEMI V8 engine mated to an eight-speed automatic transmission. On the drag strip, the beast has already delivered a production-car-record 9.65-second quarter-mile.
