Gray Design is looking to end the debate, creating what could be the absolute best vehicle for the zombie apocalypse. Meet the Sidewinder, an insane dune buggy designed for whatever you can throw at it. The project was spearheaded by the folks at Grey Design, who chose an LSX Bowtie big block engine as the power plant. The end result is a setup that pumps out 630 horsepower and 442 lb-ft of torque, helping this beast sprint to 60 mph in just 4.2 seconds, with a top speed of 93mph.
