Unless you’ve been hiding under a proverbial rock for the last few weeks, you’re most likely familiar with the specs for the newly released Dodge Challenger SRT Demon. Just in case, here’s a quick refresher – 840 horsepower and 770 pound-feet of torque from a supercharged 6.2-liter V-8 running on 100-octane race fuel. 0-to-60 mph in 2.3 seconds. 200 pounds lighter than the Hellcat. 9.65 seconds at 140 mph in the quarter mile. 3-foot wheelies off the line. Dodge is quite clear on the matter – the Demon was built to do one job very, very well – traverse the quarter-mile run as quickly as possible while maintaining some semblance of street legality. At this point, it’s obvious this beast-mobile is quick, but there’s one tidbit of info Dodge has conveniently left out of the conversation thus far – how fast is it? To find out, we pulled out our calculator and did a little thought experiment.
