Transformer - GMC TopKick 4500

Even without the big Road Armor front bumper, big tires and tall exhaust stack, the GMC TopKick 4500 is a beast of a rig. It would be intimidating painted lavender.



Ironhide is powered by a stock 6.6-liter Duramax turbodiesel V8 as found in GM's heavy-duty pickups. But the HD pickups don't get the cool tilt front end.



The standard TopKick has massive side mirrors in order to see around utility beds and trailers. Those were swapped out for side mirrors from a Yukon for a cleaner look on Ironhide.



Since Ironhide's interior isn't seen on camera, it was left stock. For stunt drivers working during the summer of 2006 in the New Mexico desert, the best thing about Ironhide was that the A/C worked.



It's a face for Hasbro to love. Millions of kids will soon be playing with toys that look like this.



Here's GM's favorite view of Ironhide.
