We first heard of Hennessey’s wild idea to add an extra axle to the already bonkers Ram TRX in 2020. That’s when the tuner teased the Mammoth 1000 TRX 6x6 – a six-wheeled, 1,000-horsepower monster truck monstrosity. This isn’t the company’s first six-wheeled machine, so the announcement wasn’t a surprise. Today, Hennessey has announced that the TRX 6x6 is finally rolling off the production line.
That’s an eye-watering price, though there is likely nothing comparable to it on the road right now. The truck is massive, measuring 88 inches (223.52 centimeters) wide and nearly 7 feet (2.1 meters) tall. However, those numbers pale compared to the length, which is 283 inches (719 cm).
