Hennessey Mammoth 6×6

Because the 702 horsepower Ram 1500 TRX isn’t enough, Hennessey Performance Engineering has taken the pickup and bestowed it with an extra set of wheels, and a tuned 7.0-liter Hellephant engine that makes more than 1200 hp. Hennessey will build just three of the $500,000 trucks, which go on sale 9.4.2020 at noon CST.
