Hennessey's HPE850 upgrade for the 2020 Chevrolet Camaro ZL1 1LE takes the muscle car's power up to 735 rear-wheel horsepower and 706 rear-wheel lb-ft of torque. This upgrade includes a long list of components, including high-flow cylinder heads, upgraded intake and exhaust valves, high-flow air induction system and a whole lot more.

So what does this upgrade get you, aside from a 0 to 60 mph time of 2.7 seconds? An insanely brutal-sounding Camaro, that's for sure. Putting the enhanced Camaro's sound front and center is a new video from Hennessey Performance where you can hear it in action. No voiceover or talking in general, just the raw sound of the car.
