Hennessey is bragging that its tuned 6.2 supercharged GMC Yukon- 665 hp (658 lb/ft torque)- beat a Hellcat in the 1/4 mile. If you watch the video, the GMC red-lighted but the Hellcat pulled hard on the GMC at the top end. If the GMC hadn't red-lighted, there's no way that it would lose to a heavy GMC that turns the quarter in 13.4 mph at 110 mph. The GMC also had an advantage because of its 4-wheel drive. Just think how a Jeep Grand Cherokee SRT launches. https://www.youtube.com/watch?v=gjBiVEzr7dg
