The two slabs of America battled during a half-mile drag racing event, one that took place on an airstrip in California, so the drivers could easily focus on their velocity taks.
Even so, the guy behind the wheel of the Caddy wasn't exactly sharp when it came to the reaction time, thus allowing the Dodge to grab the lead. It's worth noting that this is one of those race using a human Christmas Tree.
Nevertheless, as the half-mile mark approached, the GM machine started making up for that slow take-off and you can see how the rest of the fight went in the clip below.
Fortunately, the piece of footage at the bottom of the page allows you to check out the MPH values delivered by the blown sedans at the end of the run, so you can get a clear idea on the speed difference between the two.
P.S.: It might seem like the Cadillac CTS-V that pulled the burnout at the beginning of the speed battle wasn't the same car as the one that raced the Hellcat, but that's not true. In fact, the Caddy driver decided to change the wheels between the two moments.
