The 2018 Dodge Challenger SRT Demon is the world's fastest quarter mile production car. But how does it do that? How does it hit 1.8 g's of acceleration when powered by only the rear wheels? Rear wheel drive!? Physics tells us that the maximum force a wheel can apply to the ground is equal to the normal force acting on the tire multiplied by the frictional coefficient of the tire (F=u*N). So the car needs to be able to transfer all the weight to the rear tires, and have super stick tires. This video explains how the vehicle does just that!

*IMPORTANT CORRECTION!* The 2.3 second 0-60 time is indeed from 0 mph, not after 1 ft of rollout. This is faster than the Tesla P100D to 30 mph (incorrectly stated in video). My apologies for the confusion. When I asked Dodge PR directly about the car, they told me this: ""The Demon 0-30, 0-60 and 0-100 times do NOT include the 1 ft of roll out." I interpreted this as the times did not include the time for 1 foot of rollout, however from Detroit News: "Roll-outs aren’t a fair way to do zero-60, honestly. A real zero-60 is from a dead stop. But we included (a roll-out) anyway because we knew that question would come up,” said Kuniskis in the Big Apple. “You include roll-outs in our times and it’s 2.1 seconds.”
