We are about to see a quarter mile drag race between a Dodge Challenger Hellcat and a Corvette ZR1. As we already know, the Hellcat is powered by a 6.2L HEMI engine delivering 707 hp and a 650 lb-ft of torque. The ZR1 is powered by a 6.2L Supercharged OHV V8 engine delivering 638 hp and a 604 lb-ft of torque. Chevy calls this engine the LS9, it is loud on the track, quiet on the streets and it can offer a tremendous power. Let’s watch the video below to see how powerful it is compared to the Hellcat.
