Adam Carolla’s Car Cast got a behind the scenes look at Mike Ryan’s Freightliner rally/drifting truck. Mike Ryan has been the powerhouse in big rig racing up Pikes Peak and the Mt. Washington hill climb for the past several years. He also does most of big rig stunt driving you see in movies including the chase scene in Terminator 2. Some of Carolla’s commentary is kind of stupid and he goes off with a completely irrelevant and inappropriate story at the end, but they do get some good shots of the truck. It’s got a Detroit Diesel 60 series engine with a custom Borg-Warner compound turbo setup making 1950hp and 3400+ ft-lbs of torque. It weighs almost 10,000 pounds despite of the aluminum frame rails. The rear axle is a 3-link with a Watts link and the brakes have liquid cooling.
This is the big rig Gymkhana video that Mike released a while back if you want to see the truck in action:
He also competed in the Mt. Washington hill climb rally last year in the Freightliner. It’s a similar event to Pikes Peak in that part of the course is tarmac and part of it is dirt. The footage is pretty jaw-dropping.
