Hold on to your seats: Dodge has revealed what it says is the fastest production car in the world, the 2018 Challenger SRT Demon. This street-legal muscle car has 808 horsepower (!!!!) and 717 lb-ft of torque on 91 octane gas. The track version has 840 hp and 770 lb-ft of torque on 100-plus high-octane race fuel. It gets from 0 to 60 mph in 2.3 seconds, thanks to its supercharged 6.2L HEMI Demon V8 engine. To get from 0 to 30 mph, it takes 1 second. The Challenger SRT Demon has enough power that it can do a wheelie when it takes off. The Guinness World Records certified it as the first front-wheel lift in a production car — the front tires were 2.92 fee
