This is the Ripsaw MS1, a scratch-built tracked vehicle created by Howe & Howe productions. It's very fast -- its 650-horsepower blown 427 CID V8 rockets it from 0-50 in 3.5 seconds and lets it run up to 80 mph. It's also very agile, sporting a suspension with fourteen inches of travel that lets it handle bumpy terrain with aplomb. In fact, the Howe & Howe guys say it's the fastest tracked vehicle anywhere. We can't verify that, but based on the video embedded after the jump, it's clear that the Ripsaw does indeed have some serious giddyup. Lastly, based on the photo above, it can probably be made to look like a Cobra H.I.S.S. tank with a some extra effort, increasing its awesome factor by an order of magnitude. Who do we write the check out to?
