 | Dodge has unleashed the Demon. The Fiat Chrysler brand is laying claim to the fastest production car in the U.S. The Demon Challenger is a 840-horsepower 770 pound-feet of torque monster. It can go from zero to 60 (97 kilometres per hour) in 2.3 seconds. The street-legal Demon also can hit 140 mph while running a quarter mile in 9.65 seconds, about two seconds faster than a typical muscle car.  |
 | Dodge turned up the juice on the Challenger SRT Hellcat’s 707 hp 6.2-liter supercharged engine. It updated more than half of its parts and added a laundry list of production-first and high tech features. |  |
 | Instead of a simple cold air intake, the Demon cools things down by routing refrigerant from its air conditioner system through a chilling unit that helps drop the temperature of the ambient air by up to 45 degrees before the supercharger stuffs it into the cylinder. |  |
 | The Demon gets a dedicated High Octane mode to take advantage of 100+ octane unleaded race gas. Power is delivered to the rear wheels through an 8-speed automatic transmission that’s been re-engineered to handle the torque, a stronger drive shaft, and a beefed-up rear axle. |  |
