The Dodge Demon is a car of impressive numbers. It has 808 horsepower (which climbs to 840 on race fuel), it can complete the quarter-mile in 9.65 seconds and can hustle from 0-60 mph in 2.3 seconds. One of the more awe-inspiring figures related to the Demon doesn’t pertain to how fast the vehicle is, though, but to how well it slows down.
The Demon’s brake system consists of steel- two-piece vented and slotted rotors measuring 14.2 inches up front and 13.8 inches in the rear with four-piston Brembo front calipers and two-piston Brembo rear calipers. That system slows the Demon from 60 mph to 0 in just 97-feet, which is impressive considering the Demon weighs a significant 4,280 lbs.
Compare the Demon’s braking distance with the Viper ACR’s, as Motor Authority has done, and you’ll see it slows from 60 to 0 in 101-feet. The Viper ACR’s braking system comprises 15.4-inch carbon ceramic front rotors with 6-piston Brembo calipers and 14.2-inch rear rotors with 4-piston Brembo calipers. Not only are the ACR’s brakes much more advanced, but the ACR weighs 3,374 pounds – nearly 1,000 lbs less than the Demon. So what gives?
Making the big differences here are the tires. The Demon boasts sticky Nitto drag radials measuring 315mm at all four corners, which help put the power down upon accelerating but also help stick to the Demon to the pavement under heavy braking. The ACR’s custom Kumho Ecsta tires are wide – measuring 295mm out front, but the Viper simply doesn’t have enough rubber to hang with the Demon when it comes to braking.
